Hayden-Blue River 345-kV transmission line project, Colorado  

SciTech Connect

Tri-State Generation and Transmission Association, Inc., Colorado-Ute Electric Association, Inc., Platte River Power Authority, and Western Area Power Administration propose to construct and operate approximately 90 miles of 345-kilovolt (kV) transmission line between Hayden and the Blue River Valley in Colorado. The project would involve expansion of existing substation facilities at Hayden and construction of two new substations. The line would be operated at 230 kV initially. Estimated cost of the project is $37.8 million. The new line and substation facilities would provide a backup transmission path, satisfy the long-term needs in meeting the energy requirements, improve system reliability, improve system stability for the Craig and Hayden generating stations, and leave the existing 115-kV and 138-kV lines in operation to provide additional transmission capacity that would function as backup transmission during an outage on another line. Minute amounts of lands would be displaced. Construction activities would disturb critical ranges for elk and mule deer, elk calving areas, and the mating and nesting areas of greater sandhill cranes, great blue herons, sage grouse, golden eagles, and prairie falcons. Management of timberland would damage natural vegetation. The line would traverse 3.1 miles of flood-prone area, and as many as three transmission towers would lie within the floodplain of the Colorado River. The visual quality of land crossed by the line would be degraded somewhat.

Low cost Image Transmission System  

SciTech Connect

Throughout the Department of Energy (DOE) complex, sites protect themselves with intrusion detection systems. Some of these systems have sensors in remote areas. These sensors frequently alarm -- not because they have detected a terrorist skulking around the area, but because they have detected a horse, or a dog, or a bush moving in the breeze. Even though the local security force is 99% sure there is no real threat, they must assess each of these nuisance or false alarms. Generally, the procedure consists of dispatching an inspector to drive to the area and make an assessment. This is expensive in terms of manpower and the assessment is not timely. Often, by the time the inspector arrives, the cause of the alarm has vanished. A television camera placed to view the area protected by the sensor could be used to help in this assessment, but this requires the installation of high-quality cable, optical fiber, or a microwave link. Further, to be of use at the present time, the site must have had the foresight to have installed these facilities in the past and have them ready for use now. What is needed is a device to place between the television camera and a modem connecting to a low-bandwidth channel such as radio or a telephone line. This paper discusses the development of such a device: an Image Transmission System, or ITS.

The Columbia River System : the Inside Story.  

DOE Green Energy (OSTI)

The Columbia Ricer is one of the greatest natural resources in the western United States. The river and its tributaries touch the lives of nearly every resident of the Northwest-from providing the world-famous Pacific salmon to supplying the clean natural fuel for over 75 percent of the region's electrical generation. Since early in the century, public and private agencies have labored to capture the benefits of this dynamic river. Today, dozens of major water resource projects throughout the region are fed by the waters of the Columbia Basin river system. And through cooperative efforts, the floods that periodically threaten developments near the river can be controlled. This publication presents a detailed explanation of the planning and operation of the multiple-use dams and reservoirs of the Columbia River system. It describes the river system, those who operate and use it, the agreements and policies that guide system operation, and annual planning for multiple-use operation.

RIVER PROTECTION PROJECT SYSTEM PLAN  

SciTech Connect

The U.S. Department of Energy (DOE), Office of River Protection (ORP) manages the River Protection Project (RPP). The RPP mission is to retrieve and treat Hanford's tank waste and close the tank farms to protect the Columbia River. As a result, the ORP is responsible for the retrieval, treatment, and disposal of the approximately 57 million gallons of radioactive waste contained in the Hanford Site waste tanks and closure of all the tanks and associated facilities. The previous revision of the System Plan was issued in September 2003. ORP has approved a number of changes to the tank waste treatment strategy and plans since the last revision of this document, and additional changes are under consideration. The ORP has established contracts to implement this strategy to establish a basic capability to complete the overall mission. The current strategy for completion of the mission uses a number of interrelated activities. The ORP will reduce risk to the environment posed by tank wastes by: (1) Retrieving the waste from the single-shell tanks (SST) to double-shell tanks (DST) for treatment and disposal; (2) Constructing and operating the WTP, which will safely treat all of the high-level waste (HLW) and about half of the low-activity waste (LAW) contained in the tank farms, and maximizing its capability and capacity; (3) Developing and deploying supplemental treatment capability or a second WTP LAW Facility that can safely treat about half of the LAW contained in the tank farms; (4) Developing and deploying treatment and packaging capability for transuranic (TRU) tank waste for shipment to and disposal at the Waste Isolation Pilot Plant (WIPP); (5) Deploying interim storage capacity for the immobilized HLW and shipping that waste to Yucca Mountain for disposal; (6) Operating the Integrated Disposal Facility for the disposal of immobilized LAW, along with the associated secondary waste, (7) Closing the SST and DST tank farms, ancillary facilities, and al1 waste management and treatment facilities, (8) Developing and implementing technical solutions to mitigate the impact from substantial1y increased estimates of Na added during the pretreatment of the tank waste solids, This involves a combination of: (1) refining or modifying the flowsheet to reduce the required amount of additional sodium, (2) increasing the overall LAW vitrification capacity, (3) increasing the incorporation of sodium into the LAW glass, or (4) accepting an increase in mission duration, ORP has made and continues to make modifications to the WTP contract as needed to improve projected plant performance and address known or emerging risks, Key elements of the implementation of this strategy are included within the scope of the Tank Operations Contract, currently in procurement Since 2003, the ORP has conducted over 30 design oversight assessments of the Waste Treatment and Immobilization Plant (WTP). The estimated cost at completion has increased and the schedule for construction and commissioning of the WTP has extended, The DOE, Office of Environmental Management (EM), sanctioned a comprehensive review of the WTP flowsheet, focusing on throughput. In 2005, the TFC completed interim stabilization of the SSTs and as of March 2007, has completed the retrieval of seven selected SSTs. Demonstration of supplemental treatment technologies continues. The ongoing tank waste retrieval experience, progress with supplemental treatment technologies, and changes in WTP schedule led to the FY 2007 TFC baseline submittal in November 2006. The TFC baseline submittal was developed before the WTP schedule was fully understood and approved by ORP, and therefore reflects an earlier start date for the WTP facilities. This System Plan is aligned with the current WTP schedule with hot commissioning beginning in 2018 and full operations beginning in 2019. Major decisions regarding the use of supplemental treatment and the associated technology, the ultimate needed capacity, and its relationship to the WTP have not yet been finalized.

The RPP mission is to retrieve and treat Hanford's tank waste and close the tank farms to protect the Columbia River. As a result, ORP is responsible for the retrieval, treatment, and disposal of approximately 57 million gallons 1 of radioactive waste contained in the Hanford Site waste tanks and closure2 of all the tanks and associated facilities. The previous revision of the System Plan was issued in May 2008. ORP has made a number of changes to the tank waste treatment strategy and plans since the last revision of this document, and additional changes are under consideration. ORP has contracts in place to implement the strategy for completion of the mission and establish the capability to complete the overall mission. The current strategl involves a number of interrelated activities. ORP will reduce risk to the environment posed by tank wastes by the following: (1) Retrieving the waste from the single-shell tanks (SST) to double-shell tanks (DST) and delivering the waste to the Waste Treatment and Immobilization Plant (WTP). (2) Constructing and operating the WTP, which will safely treat all of the high-level waste (HLW) fraction contained in the tank farms. About one-third of the low-activity waste (LAW) fraction separated from the HLW fraction in the WTP will be immobilized in the WTP LAW Vitrification Facility. (3) Developing and deploying supplemental treatment capability assumed to be a second LAW vitrification facility that can safely treat about two-thirds of the LAW contained in the tank farms. (4) Developing and deploying supplemental pretreatment capability currently assumed to be an Aluminum Removal Facility (ARF) using a lithium hydrotalcite process to mitigate sodium management issues. (5) Developing and deploying treatment and packaging capability for contact-handled transuranic (CH-TRU) tank waste for possible shipment to and disposal at the Waste Isolation Pilot Plant (WIPP) in New Mexico. (6) Deploying interim storage capacity for the immobilized high-level waste (IHLW) pending determination of the final disposal pathway. (7) Closing the SST and DST tank farms, ancillary facilities, and all associated waste management and treatment facilities. (8) Optimizing the overall mission by resolution of technical and programmatic uncertainties, configuring the tank farms to provide a steady, well-balanced feed to the WTP, and performing trade-offs of the required amount and type of supplemental treatment and of the amount of HLW glass versus LAW glass. ORP has made and continues to make modifications to the WTP contract as needed to improve projected plant performance and address known or emerging risks. Key elements needed to implement the strategy described above are included within the scope of the Tank Operations Contract (TOC). Interim stabilization of the SSTs was completed in March 2004. As of April 2009, retrieval of seven SSTs has been completed and retrieval of four additional SSTs has been completed to the limits of technology. Demonstration of supplemental LAW treatment technologies has stopped temporarily pending revision of mission need requirements. Award of a new contract for tank operations (TOC), the ongoing tank waste retrieval experience, HLW disposal issues, and uncertainties in waste feed delivery and waste treatment led to the revision of the Performance Measurement Baseline (PM B), which is currently under review prior to approval. 6 This System Plan is aligned with the current WTP schedule, with hot commissioning beginning in 2018, and full operations beginning in late 2019. Major decisions regarding the use of supplemental treatment and the associated technology, the ultimate needed capacity, and its relationship to the WTP have not yet been finalized. This System Plan assumes that the outcome of these decisions will be to provide a second LAW vitrification facility. No final implementation decisions regarding supplemental technology can be made until the Tank Closure and

The ORP will reduce risk to the environment posed by tank wastes by: (1) Retrieving the waste from the single-shell tanks (SST) to double-shell tanks (DST) for treatment and disposal; (2) Constructing and operating the WTP, which will safely treat all of the high-level waste (HLW) and about half of the low-activity waste (LAW) contained in the tank farms, and maximizing its capability and capacity; (3) Developing and deploying supplemental treatment capability or a second WTP LAW Facility that can safely treat about half of the LAW contained in the tank farms; (4) Developing and deploying treatment and packaging capability for transuranic (TRU) tank waste for shipment to and disposal at the Waste Isolation Pilot Plant (WIPP); (5) Deploying interim storage capacity for the immobilized HLW and shipping that waste to Yucca Mountain for disposal; (6) Operating the Integrated Disposal Facility for the disposal of immobilized LAW, along with the associated secondary waste, (7) Closing the SST and DST tank farms, ancillary facilities, and al1 waste management and treatment facilities, (8) Developing and implementing technical solutions to mitigate the impact from substantial1y increased estimates of Na added during the pretreatment of the tank waste solids, This involves a combination of: (1) refining or modifying the flowsheet to reduce the required amount of additional sodium, (2) increasing the overall LAW vitrification capacity, (3) increasing the incorporation of sodium into the LAW glass, or (4) accepting an increase in mission duration, ORP has made and continues to make modifications to the WTP contract as needed to improve projected plant performance and address known or emerging risks, Key elements of the implementation of this strategy are included within the scope of the Tank Operations Contract, currently in procurement Since 2003, the ORP has conducted over 30 design oversight assessments of the Waste Treatment and Immobilization Plant (WTP). The estimated cost at completion has increased and the schedule for construction and commissioning of the WTP has extended, The DOE, Office of Environmental Management (EM), sanctioned a comprehensive review of the WTP flowsheet, focusing on throughput. In 2005, the TFC completed interim stabilization of the SSTs and as of March 2007, has completed the retrieval of seven selected SSTs. Demonstration of supplemental treatment technologies continues. The ongoing tank waste retrieval experience, progress with supplemental treatment technologies, and changes in WTP schedule led to the FY 2007 TFC baseline submittal in November 2006. The TFC baseline submittal was developed before the WTP schedule was fully understood and approved by ORP, and therefore reflects an earlier start date for the WTP facilities. This System Plan is aligned with the current WTP schedule with hot commissioning beginning in 2018 and full operations beginning in 2019. Major decisions regarding the use of supplemental treatment and the associated technology, the ultimate needed capacity, and its relationship to the WTP have not yet been finalized. This System Plan assumes that the outcome of

RIVER PROTECTION PROJECT SYSTEM PLAN  

Science Conference Proceedings (OSTI)

The U.S. Department of Energy (DOE), Office of River Protection (ORP) manages the River Protection Project (RPP). The RPP mission is to retrieve and treat Hanford's tank waste and close the tank farms to protect the Columbia River. As a result, ORP is responsible for the retrieval, treatment, and disposal of approximately 57 million gallons 1 of radioactive waste contained in the Hanford Site waste tanks and closure2 of all the tanks and associated facilities. The previous revision of the System Plan was issued in May 2008. ORP has made a number of changes to the tank waste treatment strategy and plans since the last revision of this document, and additional changes are under consideration. ORP has contracts in place to implement the strategy for completion of the mission and establish the capability to complete the overall mission. The current strategl involves a number of interrelated activities. ORP will reduce risk to the environment posed by tank wastes by the following: (1) Retrieving the waste from the single-shell tanks (SST) to double-shell tanks (DST) and delivering the waste to the Waste Treatment and Immobilization Plant (WTP). (2) Constructing and operating the WTP, which will safely treat all of the high-level waste (HLW) fraction contained in the tank farms. About one-third of the low-activity waste (LAW) fraction separated from the HLW fraction in the WTP will be immobilized in the WTP LAW Vitrification Facility. (3) Developing and deploying supplemental treatment capability assumed to be a second LAW vitrification facility that can safely treat about two-thirds of the LAW contained in the tank farms. (4) Developing and deploying supplemental pretreatment capability currently assumed to be an Aluminum Removal Facility (ARF) using a lithium hydrotalcite process to mitigate sodium management issues. (5) Developing and deploying treatment and packaging capability for contact-handled transuranic (CH-TRU) tank waste for possible shipment to and disposal at the Waste Isolation Pilot Plant (WIPP) in New Mexico. (6) Deploying interim storage capacity for the immobilized high-level waste (IHLW) pending determination of the final disposal pathway. (7) Closing the SST and DST tank farms, ancillary facilities, and all associated waste management and treatment facilities. (8) Optimizing the overall mission by resolution of technical and programmatic uncertainties, configuring the tank farms to provide a steady, well-balanced feed to the WTP, and performing trade-offs of the required amount and type of supplemental treatment and of the amount of HLW glass versus LAW glass. ORP has made and continues to make modifications to the WTP contract as needed to improve projected plant performance and address known or emerging risks. Key elements needed to implement the strategy described above are included within the scope of the Tank Operations Contract (TOC). Interim stabilization of the SSTs was completed in March 2004. As of April 2009, retrieval of seven SSTs has been completed and retrieval of four additional SSTs has been completed to the limits of technology. Demonstration of supplemental LAW treatment technologies has stopped temporarily pending revision of mission need requirements. Award of a new contract for tank operations (TOC), the ongoing tank waste retrieval experience, HLW disposal issues, and uncertainties in waste feed delivery and waste treatment led to the revision of the Performance Measurement Baseline (PM B), which is currently under review prior to approval. 6 This System Plan is aligned with the current WTP schedule, with hot commissioning beginning in 2018, and full operations beginning in late 2019. Major decisions regarding the use of supplemental treatment and the associated technology, the ultimate needed capacity, and its relationship to the WTP have not yet been finalized. This System Plan assumes that the outcome of these decisions will be to provide a second LAW vitrification facility. No final implementation decisions regarding supplemental technology can be made until the Tank Closure and

Multi-transmission-line-beam interactive system  

E-Print Network (OSTI)

We construct here a Lagrangian field formulation for a system consisting of an electron beam interacting with a slow-wave structure modeled by a possibly non-uniform multiple transmission line (MTL). In the case of a single line we recover the linear model of a traveling wave tube (TWT) due to J.R. Pierce. Since a properly chosen MTL can approximate a real waveguide structure with any desired accuracy, the proposed model can be used in particular for design optimization. Furthermore, the Lagrangian formulation provides for: (i) a clear identification of the mathematical source of amplification, (ii) exact expressions for the conserved energy and its flux distributions obtained from the Noether theorem. In the case of uniform MTLs we carry out an exhaustive analysis of eigenmodes and find sharp conditions on the parameters of the system to provide for amplifying regimes.

Flood Forecasting in River System Using ANFIS  

Science Conference Proceedings (OSTI)

The aim of the present study is to investigate applicability of artificial intelligence techniques such as ANFIS (Adaptive Neuro-Fuzzy Inference System) in forecasting flood flow in a river system. The proposed technique combines the learning ability of neural network with the transparent linguistic representation of fuzzy system. The technique is applied to forecast discharge at a downstream station using flow information at various upstream stations. A total of three years data has been selected for the implementation of this model. ANFIS models with various input structures and membership functions are constructed, trained and tested to evaluate efficiency of the models. Statistical indices such as Root Mean Square Error (RMSE), Correlation Coefficient (CORR) and Coefficient of Efficiency (CE) are used to evaluate performance of the ANFIS models in forecasting river flood. The values of the indices show that ANFIS model can accurately and reliably be used to forecast flood in a river system.

This system allows for selective power transmission among terminals in an interconnected system, and is enabled by power electronic technology. The dissertation starts with a presentation of some of the challenges faced by modern power systems, and includes a description of various power system technologies developed in an attempt to solve them. Then, our proposed solution is presented as an alternative to electric power transmission, and the fundamental concepts are explained. A version of the MFPS is developed, which has relevance to the problem of renewable sources integration. This AC DC Power System is further explored, and the topology of the system and the converters is presented, as well as the control techniques used in its operation. The dissertation also presents a performance study of the AC DC system, which was done in Simulink, and it demonstrates the robustness of the system under various dynamic and fault conditions. Finally, a summary of the work is given in the last section of the dissertation. The contributions of our research to the state of technology are discussed. These contributions include: the demonstration of power selectivity based on frequency identification, the development of a novel transmission system and a AC DC integrated implementation of it, and the development of a control and converter that enables selective power transmission. Also, some of the most relevant future research initiatives related to this topic are presented.

Large hydrofoil transmission system study. Final report  

SciTech Connect

This report presents the results of a study to determine the performance and physical characteristics of an ac electrical system intended for use as the propulsion system of large hydrofoils. Section I provides a technical description of the system in terms of performance, weight and component characteristics. Section II describes anticipated problems associated with development of the system and its components, and includes activities through design and fabrication, and qualification of an integrated system. Two system configurations are considereed in this study. Configuration I which is the preferred one, consists of two direct-turbine-driven ac generators supplying electrical power to either foilborne or hullborne propeller induction drive motors. Conventional switchgear is used for connecting the generator to either the foil or hull drive motors. Each induction motor supplies power to a fixed pitch propeller via a planetary type gearbox. Speed and power output of each induction motor is controlled by fuel to the turbine. Configuration II consists of independent foilborne and hullborne propulsion systems. For takeoff and foilborne operation, two direct LM2500 turbine-drive ac generators supply electrical power to the foil propeller induction motors. Operation in this mode is identical to Configuration I. Configuration II provides a trade off between greater system weight, against a lower hullborne fuel consumption rate obtained by operating smaller turbines in hullborne mode. This provides, potentially, a greater hullborne range.

Recent progress on system studies for long distance power transmission  

SciTech Connect

Two possible applications of helium-cooled underground cables for power transmission were studied to determine network characteristics and estimated costs. The first involved power transmission at 345 kV from a Long Island nuclear power plant to a substation 43 miles away. The second appication examined the feasibility of a 350 mi-long 550 kV transmission line from Western Pennsylvania to Allentown and Philadelphia. For both systems computer simulations were used to study operating characteristics. A detailed cost analysis was made. The Long Island study concluded that helium-cooled cables were well suited for high-power transmission in a suburban area, that such a system using two trenches and separate refrigerator stations would be more reliable than a single trench system, and that cost could be optimized by using a less expensive cryogenic envelope. The Pennsylvania study showed that the helium-cooled cable was technically capable of performing as well as overhead power lines, but the cost of the underground cryogenic system is so much greater that such a system could not be economically justified for long distance transmission across open country-side.

Comparative Evaluation of Generalized River/Reservoir System Models  

E-Print Network (OSTI)

This report reviews user-oriented generalized reservoir/river system models. The terms reservoir/river system, reservoir system, reservoir operation, or river basin management "model" or "modeling system" are used synonymously to refer to computer modeling systems that simulate the storage, flow, and diversion of water in a system of reservoirs and river reaches. Generalized means that a computer modeling system is designed for application to a range of concerns dealing with river basin systems of various configurations and locations, rather than being site-specific customized to a particular system. User-oriented implies the modeling system is designed for use by professional practitioners (model-users) other than the original model developers and is thoroughly tested and well documented. User-oriented generalized modeling systems should be convenient to obtain, understand, and use and should work correctly, completely, and efficiently. Modeling applications often involve a system of several simulation models, utility software products, and databases used in combination. A reservoir/river system model is itself a modeling system, which often serves as a component of a larger modeling system that may include watershed hydrology and river hydraulics models, water quality models, databases and various software tools for managing time series, spatial, and other types of data. Reservoir/river system models are based on volume-balance accounting procedures for tracking the movement of water through a system of reservoirs and river reaches. The model computes reservoir storage contents, evaporation, water supply withdrawals, hydroelectric energy generation, and river flows for specified system operating rules and input sequences of stream inflows and net evaporation rates. The hydrologic period-of-analysis and computational time step may vary greatly depending on the application. Storage and flow hydrograph ordinates for a flood event occurring over a few days may be determined at intervals of an hour or less. Water supply capabilities may be modeled with a monthly time step and several decade long period-of-analysis capturing the full range of fluctuating wet and dry periods including extended drought. Stream inflows are usually generated outside of the reservoir/river system model and provided as input to the model. However, reservoir/river system models may also include capabilities for modeling watershed precipitation-runoff processes to generate inflows to the river/reservoir system. Some reservoir/river system models simulate water quality constituents along with water quantities. Some models include features for economic evaluation of system performance based on cost and benefit functions expressed as a function of flow and storage.

Analysis of the ITER LFS Reflectometer Transmission Line System  

Science Conference Proceedings (OSTI)

A critical issue in the design of the ITER Low Field Side (LFS) reflectometer is the transmission line (TL) system. A TL connects each launcher to a diagnostic instrument. Each TL will typically consist of ~42 m of corrugated waveguide and up to 10 miter bends. Important issues for the performance of the TL system are mode conversion and reflections. Minimizing mode conversion and reflections in the waveguide are critical to minimizing standing waves and phase errors in the reflectometer-measured phase. The performance of the corrugated waveguide and miter bends is analyzed and recommendations given.

A WWW interactive progressive local image transmission system  

E-Print Network (OSTI)

We present a JAVA-based Interactive Progressive Local Image Transmission (IPLIT) system for viewing large images over the bandwidth-limited World Wide Web (WWW) in "reasonable (i.e. usable) time". One motivation behind this research is the need for medical specialists to remotely view medical images, in reasonable time, over the WWW. In our IPLIT system, the user employs a JAVA-enabled Internet browser to view and browse a low resolution image. The identification of features or regions of interest before observing those regions in detail is performed by either selecting a particular region manually via mouse or by utilizing an automatic feature-detection mode. The automatic feature-detection displays high-resolution subimages along a trajectory determined by the user-specified feature of interest. Our program handles 3D image data as a sequence of 2D images. Our IPLIT system is tested on actual MRI, CT and Ultrasound medical images obtained from the Robarts Research Institute at the Un...

In particular, instrumental design and engineering is oriented towards protection of human health in the Arctic, and with the additional goal of advancing Arctic education and research. POLARATS will obtain and transmit environmental data from hardened monitoring devices deployed in locations important to understanding atmospheric and aquatic pollutant migration as it is biomagnified in Arctic food chains. An Internet- and personal computer (PC)-based educational module will provide real time sensor data, on-line educational content, and will be integrated with workbooks and textbooks for use in middle and high school science programs. The educational elements of POLARATS include an Internet-based educational module that will instruct students in the use of the data and how those data fit into changing Arctic environments and food chains. POLARATS will: (1) Enable students, members of the community, and scientific researchers to monitor local environmental conditions in real time over the Internet; and (2) Provide additional educational benefits through integration with middle- and high-school science curricula. Information will be relayed from POLARATS devices to classrooms and libraries along with custom-designed POLARATS teaching materials that will be integrated into existing curricula to enhance the educational benefits realized from the information obtained.

Water geochemistry of hydrothermal systems, Wood River District, Idaho  

DOE Green Energy (OSTI)

Hydrothermal systems of the Wood River District, central Idaho, have been studied by geologic mapping of thermal spring areas and geochemical investigations of thermal and non-thermal waters. This report summarizes the new geochemical data gathered during the study. Integration of the results of geological and geochemical studies has led to development of a target model for hydrothermal resources on the margin of the Idaho Batholith. Warfield Hot Springs, with temperatures up to 58/sup 0/C, flow from a major shear zone along the margin of an apophysis of the batholith.

Virtual Pipeline System Testbed to Optimize the U.S. Natural Gas Transmission Pipeline System  

SciTech Connect

The goal of this project is to develop a Virtual Pipeline System Testbed (VPST) for natural gas transmission. This study uses a fully implicit finite difference method to analyze transient, nonisothermal compressible gas flow through a gas pipeline system. The inertia term of the momentum equation is included in the analysis. The testbed simulate compressor stations, the pipe that connects these compressor stations, the supply sources, and the end-user demand markets. The compressor station is described by identifying the make, model, and number of engines, gas turbines, and compressors. System operators and engineers can analyze the impact of system changes on the dynamic deliverability of gas and on the environment.

System for computer controlled shifting of an automatic transmission  

DOE Patents (OSTI)

In an automotive vehicle having an automatic transmission that driveably connects a power source to the driving wheels, a method to control the application of hydraulic pressure to a clutch, whose engagement produces an upshift and whose disengagement produces a downshift, the speed of the power source, and the output torque of the transmission. The transmission output shaft torque and the power source speed are the controlled variables. The commanded power source torque and commanded hydraulic pressure supplied to the clutch are the control variables. A mathematical model is formulated that describes the kinematics and dynamics of the powertrain before, during and after a gear shift. The model represents the operating characteristics of each component and the structural arrangement of the components within the transmission being controlled. Next, a close loop feedback control is developed to determine the proper control law or compensation strategy to achieve an acceptably smooth gear ratio change, one in which the output torque disturbance is kept to a minimum and the duration of the shift is minimized. Then a computer algorithm simulating the shift dynamics employing the mathematical model is used to study the effects of changes in the values of the parameters established from a closed loop control of the clutch hydraulic and the power source torque on the shift quality. This computer simulation is used also to establish possible shift control strategies. The shift strategies determine from the prior step are reduced to an algorithm executed by a computer to control the operation of the power source and the transmission.

Transmission needs across a fully renewable European power system  

E-Print Network (OSTI)

The residual load and excess power generation of 27 European countries with a 100% penetration of variable renewable energy sources are explored in order to quantify the benefit of power transmission between countries. Estimates are based on extensive weather data, which allows for modelling of hourly mismatches between the demand and renewable generation from wind and solar photovoltaics. For separated countries, balancing is required to cover around 24% of the total annual energy consumption. This number can be reduced down to 15% once all countries are networked together with uncon- strained interconnectors. The reduction represents the maximum possible benefit of transmission for the countries. The total Net Transfer Capacity of the unconstrained interconnectors is roughly twelve times larger than current values. However, constrained interconnector capacities six times larger than the current values are found to provide 97% of the maximum possible benefit of cooperation. This motivates a detailed investig...

The integration of renewable energy sources into electric power transmission systems  

DOE Green Energy (OSTI)

Renewable energy technologies such as photovoltaics, solar thermal power plants, and wind turbines are nonconventional, environmentally attractive sources of energy that can be considered for electric power generation. Many of the areas with abundant renewable energy resources (very sunny or windy areas) are far removed from major load centers. Although electrical power can be transmitted over long distances of many hundreds of miles through high-voltage transmission lines, power transmission systems often operate near their limits with little excess capacity for new generation sources. This study assesses the available capacity of transmission systems in designated abundant renewable energy resource regions and identifies the requirements for high-capacity plant integration in selected cases. In general, about 50 MW of power from renewable sources can be integrated into existing transmission systems to supply local loads without transmission upgrades beyond the construction of a substation to connect to the grid. Except in the Southwest, significant investment to strengthen transmission systems will be required to support the development of high-capacity renewable sources of 1000 MW or greater in areas remote from major load centers. Cost estimates for new transmission facilities to integrate and dispatch some of these high-capacity renewable sources ranged from several million dollars to approximately one billion dollars, with the latter figure an increase in total investment of 35%, assuming that the renewable source is the only user of the transmission facility.

Columbia River Hatchery Reform System-Wide Report.  

SciTech Connect

The US Congress funded the Puget Sound and Coastal Washington Hatchery Reform Project via annual appropriations to the US Fish and Wildlife Service (USFWS) beginning in fiscal year 2000. Congress established the project because it recognized that while hatcheries have a necessary role to play in meeting harvest and conservation goals for Pacific Northwest salmonids, the hatchery system was in need of comprehensive reform. Most hatcheries were producing fish for harvest primarily to mitigate for past habitat loss (rather than for conservation of at-risk populations) and were not taking into account the effects of their programs on naturally spawning populations. With numerous species listed as threatened or endangered under the Endangered Species Act (ESA), conservation of salmon in the Puget Sound area was a high priority. Genetic resources in the region were at risk and many hatchery programs as currently operated were contributing to those risks. Central to the project was the creation of a nine-member independent scientific review panel called the Hatchery Scientific Review Group (HSRG). The HSRG was charged by Congress with reviewing all state, tribal and federal hatchery programs in Puget Sound and Coastal Washington as part of a comprehensive hatchery reform effort to: conserve indigenous salmonid genetic resources; assist with the recovery of naturally spawning salmonid populations; provide sustainable fisheries; and improve the quality and cost-effectiveness of hatchery programs. The HSRG worked closely with the state, tribal and federal managers of the hatchery system, with facilitation provided by the non-profit organization Long Live the Kings and the law firm Gordon, Thomas, Honeywell, to successfully complete reviews of over 200 hatchery programs at more than 100 hatcheries across western Washington. That phase of the project culminated in 2004 with the publication of reports containing the HSRG's principles for hatchery reform and recommendations for Puget Sound/Coastal Washington hatchery programs, followed by the development in 2005 of a suite of analytical tools to support application of the principles (all reports and tools are available at www.hatcheryreform.us). In 2005, Congress directed the National Oceanic and Atmospheric Administration-Fisheries (NOAA Fisheries) to replicate the Puget Sound and Coastal Washington Hatchery Reform Project in the Columbia River Basin. The HSRG was expanded to 14 members to include individuals with specific knowledge about the Columbia River salmon and steelhead populations. This second phase was initially envisioned as a one-year review, with emphasis on the Lower Columbia River hatchery programs. It became clear however, that the Columbia River Basin needed to be viewed as an inter-connected ecosystem in order for the review to be useful. The project scope was subsequently expanded to include the entire Basin, with funding for a second year provided by the Bonneville Power Administration (BPA) under the auspices of the Northwest Power and Conservation Council's (NPCC) Fish and Wildlife Program. The objective of the HSRG's Columbia River Basin review was to change the focus of the Columbia River hatchery system. In the past, these hatchery programs have been aimed at supplying adequate numbers of fish for harvest as mitigation primarily for hydropower development in the Basin. A new, ecosystem-based approach is founded on the idea that harvest goals are sustainable only if they are compatible with conservation goals. The challenge before the HSRG was to determine whether or not conservation and harvest goals could be met by fishery managers and, if so, how. The HSRG determined that in order to address these twin goals, both hatchery and harvest reforms are necessary. The HSRG approach represents an important change of direction in managing hatcheries in the region. It provides a clear demonstration that current hatchery programs can indeed be redirected to better meet both conservation and harvest goals. For each Columbia River Basin Environmentally Si

Evaluation of power system security and development of transmission pricing method  

E-Print Network (OSTI)

The electric power utility industry is presently undergoing a change towards the deregulated environment. This has resulted in unbundling of generation, transmission and distribution services. The introduction of competition into unbundled electricity services may lead system operation closer to its security boundaries resulting in smaller operating safety margins. The competitive environment is expected to lead to lower price rates for customers and higher efficiency for power suppliers in the long run. Under this deregulated environment, security assessment and pricing of transmission services have become important issues in power systems. This dissertation provides new methods for power system security assessment and transmission pricing. In power system security assessment, the following issues are discussed 1) The description of probabilistic methods for power system security assessment 2) The computation time of simulation methods 3) on-line security assessment for operation. A probabilistic method using Monte-Carlo simulation is proposed for power system security assessment. This method takes into account dynamic and static effects corresponding to contingencies. Two different Kohonen networks, Self-Organizing Maps and Learning Vector Quantization, are employed to speed up the probabilistic method. The combination of Kohonen networks and Monte-Carlo simulation can reduce computation time in comparison with straight Monte-Carlo simulation. A technique for security assessment employing Bayes classifier is also proposed. This method can be useful for system operators to make security decisions during on-line power system operation. This dissertation also suggests an approach for allocating transmission transaction costs based on reliability benefits in transmission services. The proposed method shows the transmission transaction cost of reliability benefits when transmission line capacities are considered. The ratio between allocation by transmission line capacity-use and allocation by reliability benefits is computed using the probability of system failure.

Systems and methods that provide up to complete transmission of ions between coupled stages with low effective ion losses. An "interfaceless" electrospray ionization system is further described that operates an electrospray at a reduced pressure such that standard electrospray sample solutions can be directly sprayed into an electrodynamic ion funnel which provides ion focusing and transmission of ions into a mass analyzer. Furthermore, chambers maintained at different pressures can allow for more optimal operating conditions for an electrospray emitter and an ion guide.

Improved neutron monitor systems for Savannah River Site separations facilities  

Science Conference Proceedings (OSTI)

The Savannah River Laboratory (SRL), in conjunction with Savannah River Site (SRS) Separations Technology personnel, has developed and implemented a comprehensive program to improve the performance and reliability of neutron detector systems (neutron monitors) in the SRS separations areas. The neutron monitors, which monitor the buildup of fissile material in the mixer-settler banks of the solvent extraction process, are important nuclear safety control devices. A review of the performance history of the neutron monitors reveals that many of the systems exhibit problems arising from several causes, including: low neutron sensitivity, high susceptibility to electromagnetic interferences (due to long cable runs between detectors and their electronics), and high maintenance requirements. To address these problems, the neutron monitor improvement program encompasses both technical and administrative improvements, including: substitution of more sensitive neutron monitors at many locations in the solvent extraction areas, the development of an integrated preamplifier/amplifier package to eliminate long cable runs, and improvements in the neutron monitor functional test procedures to reduce maintenance requirements. The implementation of these improvements, already partially complete, is expected to provide enhanced operation and reliability for the neutron monitors. This paper will present a description of the solvent neutron monitors as well as technical details of the improvement program. 2 refs., 5 figs., 1 tab.

With regard to the workshop questions posed on physical limits of existing transmission facilities and methods to facilitate access to renewable resources, we wish to call your attention to some actual results observed at a utility in the southwest U.S. using Dynamic Line Rating technology to optimize access to wind farm energy production while ensuring transmission grid reliability, all at minimal cost to the utility and its ratepayers. The bottom line is that Dynamic Line Rating technology enables transmission system operators to utilize the natural correlation that exists between wind farm output and real (not assumed) transmission line capacity. This is not theorized, but rather has been proven and successfully implemented. We strongly recommend that CEC and CPUC take the time to fully understand Dynamic Line Rating

Particle trap for compressed gas insulated transmission systems  

DOE Patents (OSTI)

A particle trap is provided for gas insulated transmission lines having a central high voltage conductor supported within an outer coaxial conductive sheath by a dielectric support member. A cavity between the inner conductor and outer sheath is filled with a dielectric insulating gas. A cone-like particle deflector, mounted to the inner conductor, deflects moving particles away from the support member, to radially outer portions of the cavity. A conductive shield is disposed adjacent the outer sheath to form a field-free region in radially outer portions of the cavity, between the shield and the sheath. Particles traveling along the cavity are deflected by the cone-like deflector into the field-free region where they are held immobile. In a vertical embodiment, particles enter the field-free region through an upper end of a gap formed between shield and sheath members. In a horizontal embodiment, the deflector cone has a base which is terminated radially internally of the shield. Apertures in the shield located adjacent the deflector allow passage of deflected particles into the field-free region. The dielectric support member is thereby protected from contaminating particles that may otherwise come to rest thereon.

Combined transmission distribution load flow model employing system reduction and voltage variable load representation  

SciTech Connect

In the few decades since its introduction the digital computer has found widespread application within the electric power industry. One of the more fruitful areas for its utilization has been in the determination of the steady-state voltage conditions throughout the system. A power system naturally breaks down into two very distinct parts: transmission and distribution, and traditionally, the voltage problem has been separated the same way. In the transmission system it is referred to as a load flow problem, and in the distribution part it is called a voltage profile. In addition, the loads are often treated differently. Transmission loads are usually considered to be constant power, and the equations that result are therefore nonlinear. In the distribution portion the loads, though specified in terms of power, are sometimes handled as constant impedances, with linear equations. This work produced a new model wherein a mesh transmission system is combined with a radial distribution system and they are solved simultaneously. A system reduction technique is used to eliminate part of the transmission system from consideration, and thereby keep the problem at a manageable size. The solution algorithm incorporates a voltage variable load model which approximates the behavior of real loads more nearly than the common representations.

Electric power transmission and distribution systems: costs and their allocation. Research report  

SciTech Connect

Transmission and distribution costs contribute significantly to the total costs of providing electrical service. The costs derived from the transmission and distribution (TandD) system have historically comprised about 2/3 the costs of producing and delivering electricity to residential-commercial customers, and over 1/3 the total costs supplying electricity to large industrial customers. This report: (1) estimates the differences in transmission and distribution equipment required to serve industrial and residential-commercial customers and allocates to the above two customer classes the average costs of installing this equipment; (2) estimates the costs of operation and maintenance of the transmission and distribution system, and allocates these costs to the customer classes; and (3) calculates the TandD derived average costs for the two customer classes.

The Reliability Investigation on ACSR Splice Connector Systems Used in Overhead Power transmission Lines  

SciTech Connect

Due to material discontinuity and inherited forming mechanism from a crimped-type splice connector, the associated conductor-connector system is highly sensitive to system components aging, especially during high-temperature operations. Furthermore, due to the increase in power demand and limited investment in new infrastructure, existing overhead power transmission lines often need to operate at temperatures higher than the original designed values. This has led to the accelerated aging and degradation of conductor-connector systems. The implications of connector aging are two-fold: (1) significant increase in resistivity of the splice connector and (2) significant reduction in the connector clamping strength. Therefore, splice connectors are one of the weakest links in the electric power transmission infrastructure. In this paper we will discuss the reliability of splice connector systems, including both single stage and two stage splice connectors, used in ACSR conductor of transmission lines under high temperature operations.

Stabilizing control of parallel AC-DC power transmission systems by approximate switching curve  

SciTech Connect

A method to improve the transient stability of bulk power transmission system is presented. The method stabilizes the control of parallel ac-dc transmission systems using an approximate switching curve. The optimal switching curve is approximated by a power series and the resulting switching curve is determined independent of type and duration of faults that occur to the system. In addition, coefficients of the switching curve can be calculated on a off-line basis which allows use of simple on-line algebraic calculations in emergency conditions.

Sensor, method and system of monitoring transmission lines  

SciTech Connect

An apparatus, method, and system for measuring the magnetic field produced by phase conductors in multi-phase power lines. The magnetic field measurements are used to determine the current load on the conductors. The magnetic fields are sensed by coils placed sufficiently proximate the lines to measure the voltage induced in the coils by the field without touching the lines. The x and y components of the magnetic fields are used to calculate the conductor sag, and then the sag data, along with the field strength data, can be used to calculate the current load on the line and the phase of the current. The sag calculations of this invention are independent of line voltage and line current measurements. The system applies a computerized fitter routine to measured and sampled voltages on the coils to accurately determine the values of parameters associated with the overhead phase conductors.

Environmental data management system at the Savannah River Site  

SciTech Connect

The volume and complexity of data associated with escalating environmental regulations has prompted professionals at the Savannah River Site to begin taking steps necessary to better manage environmental information. This paper describes a plan to implement an integrated environmental information system at the site. Nine topic areas have been identified. They are: administrative, air, audit & QA, chemical information/inventory, ecology, environmental education, groundwater, solid/hazardous waste, and surface water. Identification of environmental databases that currently exist, integration into a ``friendly environment,`` and development of new applications will all take place as a result of this effort. New applications recently completed include Groundwater Well Construction, NPDES (Surface Water) Discharge Monitoring, RCRA Quarterly Reporting, and Material Safety Data Sheet Information. Database applications are relational (Oracle RDBMS) and reside largely in DEC VMS environments. In today`s regulatory and litigation climate, the site recognizes they must have knowledge of accurate environmental data at the earliest possible time. Implementation of this system will help ensure this.

Study of transmission and protection elements for wind energy generating systems. Volume 1  

DOE Green Energy (OSTI)

Results are reported of a study at Cornell University on transmission, distribution, and protection systems for large wind-energy generators (WEG) connected to an electric utility grid. Configurations for wind farms on flat terrain, mountain-peak clusters, and installations along a ridge were examined. Computer studies of load-flow and short-circuit behavior confirmed the technical feasibility of the proposed systems. Realistic unit costs for the projected transmission and protection schemes range from $109 to $317 per Kw, depending upon choice of configuration and distance from the grid. Cost of protective equipment is found to be a major factor in most cases, tending to be equal or greater than transmission line costs when the WEG units are located five miles or less from the grid. Several alternatives are suggested for future study.

Corrosion of Buried Steel Pipes Used With Transmission Pipe-Type Cable Systems  

Science Conference Proceedings (OSTI)

Although pipe-type underground transmission cables were designed with a life expectancy of 40 years, many of these cables have reached this threshold and are still performing satisfactorily. The buried steel pipes that surround the cables are protected by coatings and cathodic-protection systems. These protective systems need to be routinely inspected and maintained in order to extend their own life expectancy and thereby protect the cables within the steel pipes. This report provides research results an...

The design of high-speed data transmission method for a small nuclear physics DAQ system  

E-Print Network (OSTI)

A large number of data need to be transmitted in high-speed between Field Programmable Gate Array (FPGA) and Advanced RISC Machines 11 micro-controller (ARM11) when we design a small data acquisition (DAQ) system for nuclear experiments. However, it is a complex problem to beat the target. In this paper, we will introduce a method which can realize the high-speed data transmission. By this way, FPGA is designed to acquire massive data from Front-end electronics (FEE) and send it to ARM11, which will transmit the data to other computer through the TCP/IP protocol. This paper mainly introduces the interface design of the high-speed transmission between FPGA and ARM11, the transmission logic of FPGA and the driver program of ARM11. The research shows that the maximal transmission speed between FPGA and ARM11 by this way can reach 50MB/s theoretically, while in nuclear physics experiment, the system can acquire data with the speed of 2.2MB/s.

Transmission Line Inspires A New Distributed Algorithm to Solve the Nonlinear Dynamical System of Physical Circuit  

E-Print Network (OSTI)

As known, physical circuits, e.g. integrated circuits or power system, work in a distributed manner, but these circuits could not be easily simulated in a distributed way. This is mainly because that the dynamical system of physical circuits is nonlinear and the linearized system of physical circuits is non-symmetrical. This paper proposes a simple and natural strategy to simulate the physical circuit in parallel, by mimicking the internal wires or interconnects inside the circuits by distributed numerical algorithm. Mimic Transmission Method (MTM) is a new distributed numerical algorithm to solve the nonlinear ordinary differential equations extracted from physical circuits. It maps the transmission delay of interconnects between subcircuits to the communication delay of digital data link between processors. MTM is not a global iterative algorithm, and it does only one distributed computation at each time window to obtain accurate result, so unconvergence issues do not need to be worried about.

DOE Green Energy (OSTI)

Variable generation is on track to become a significant contributor to electric power systems worldwide. Thus, it is important to analyze the effect that renewables will have on the reliability of systems. In this paper we present a new tool being implemented at the National Renewable Energy Laboratory, which allows the inclusion of variable generation in the power system resource adequacy. The tool is used to quantify the potential contribution of transmission to reliability in highly interconnected systems and an example is provided using the Western Interconnection footprint.

Model documentation: Natural gas transmission and distribution model of the National Energy Modeling System. Volume 1  

SciTech Connect

The Natural Gas Transmission and Distribution Model (NGTDM) is the component of the National Energy Modeling System (NEMS) that is used to represent the domestic natural gas transmission and distribution system. NEMS was developed in the Office of integrated Analysis and Forecasting of the Energy information Administration (EIA). NEMS is the third in a series of computer-based, midterm energy modeling systems used since 1974 by the EIA and its predecessor, the Federal Energy Administration, to analyze domestic energy-economy markets and develop projections. The NGTDM is the model within the NEMS that represents the transmission, distribution, and pricing of natural gas. The model also includes representations of the end-use demand for natural gas, the production of domestic natural gas, and the availability of natural gas traded on the international market based on information received from other NEMS models. The NGTDM determines the flow of natural gas in an aggregate, domestic pipeline network, connecting domestic and foreign supply regions with 12 demand regions. The methodology employed allows the analysis of impacts of regional capacity constraints in the interstate natural gas pipeline network and the identification of pipeline capacity expansion requirements. There is an explicit representation of core and noncore markets for natural gas transmission and distribution services, and the key components of pipeline tariffs are represented in a pricing algorithm. Natural gas pricing and flow patterns are derived by obtaining a market equilibrium across the three main elements of the natural gas market: the supply element, the demand element, and the transmission and distribution network that links them. The NGTDM consists of four modules: the Annual Flow Module, the Capacity F-expansion Module, the Pipeline Tariff Module, and the Distributor Tariff Module. A model abstract is provided in Appendix A.

Modeling Interregional Transmission Congestion in the NationalEnergy Modeling System  

SciTech Connect

Congestion analysis using National Energy Modeling National Energy Modeling System (NEMS) or NEMS-derivatives, such as LBNL-NEMS, is subject to significant caveats because the generation logic inherent in NEMS limits the extent to which interregional transmission can be utilized and intraregional transmission is not represented at all. The EMM is designed primarily to represent national energy markets therefore regional effects may be simplified in ways that make congestion analysis harder. Two ways in particular come to mind. First, NEMS underutilizes the capability of the traditional electric grid as it builds the dedicated and detached grid. Second, it also undervalues the costs of congestion by allowing more transmission than it should, due to its use of a transportation model rather than a transmission model. In order to evaluate benefits of reduced congestion using LBNL-NEMS, Berkeley Lab identified three possible solutions: (1) implement true simultaneous power flow, (2) always build new plants within EMM regions even to serve remote load, and (3) the dedicated and detached grid should be part of the known grid. Based on these findings, Berkeley Lab recommends the following next steps: (1) Change the build logic that always places new capacity where it is needed and allow the transmission grid to be expanded dynamically. (2) The dedicated and detached grid should be combined with the traditional grid. (3) Remove the bias towards gas fired combine cycle and coal generation, which are the only types of generation currently allowed out of region. (4) A power flow layer should be embedded in LBNL-NEMS to appropriately model and limit transmission.

Supplement Analysis for the Transmission System Vegetation Management Program FEIS (DOE/EIS-0285/SA-15)  

SciTech Connect

BPA proposes to clear unwanted vegetation in the rights-of-ways and around tower structures that may impede the operation and maintenance of the subject transmission lines. Work also includes clearing of a small (<1/4 mile) section of access road. All work will be in accordance with the National Electrical Safety Code and BPA standards. See Section 1.1 of the attached checklist for detailed information on each section of the referenced transmission lines. BPA will conduct the vegetation control with the goal of removing tall-growing vegetation that is currently or will soon be a hazard to the transmission lines and where possible to promote low-growing plant communities in the right-of-way. This project meets the standards and guidelines for the Transmission System Vegetation Management Program Final Environmental Impact Statement (FEIS) and Record of Decision (ROD). The vegetation needing control is mainly Douglas Fir, Alder, and blackberries as indicated in Section 1.2 of the attached checklist. The work involved in the ROW includes: clearing tall growing vegetation that is currently or will soon pose a hazard to the lines; treating the associated stumps and re-sprouts with herbicide to ensure that the roots are killed preventing new sprouts; and selectively eliminating tall growing vegetation before it reaches a height or density to begin competing with low-growing vegetation. All work will take place in existing rights-of-ways and around transmission structures. All work will be accomplished by selective vegetation control methods to assure that there is little potential harm to non-target vegetation and to low-growing plants. The work will provide system reliability and fire protection. Also, all off right-of-way trees that are potentially unstable and will fall within a minimum distance or into the zone where the conductors swing will be removed. Access roads will be treated using mowing and herbicide applications. The work will provide system reliability. The subject transmission lines range from 115kV to 230kV and are made up of accompanying access roads, steel and wooden transmission line structures and associated switching platforms. The minimum clearance ranges from 21 feet for 115kV lines to 23 feet for 230kV lines. ROW easement widths vary along the length of the project. Vegetation control for this project is designed to provide a 3 year maintenance free interval. In summary, the overall vegetation management scheme will be to selectively remove tall growing vegetation then apply selective herbicide treatment using cut stump applications.

Regional Transmission Projects: Finding Solutions  

Science Conference Proceedings (OSTI)

The Keystone Center convened and facilitated a year-long Dialogue on "Regional Transmission Projects: Finding Solutions" to develop recommendations that will help address the difficult and contentious issues related to expansions of regional electric transmission systems that are needed for reliable and economic transmission of power within and across regions. This effort brought together a cross-section of affected stakeholders and thought leaders to address the problem with the collective wisdom of their experience and interests. Transmission owners sat at the table with consumer advocates and environmental organizations. Representatives from regional transmission organizations exchanged ideas with state and federal regulators. Generation developers explored common interests with public power suppliers. Together, the Dialogue participants developed consensus solutions about how to begin unraveling some of the more intractable issues surrounding identification of need, allocation of costs, and reaching consensus on siting issues that can frustrate the development of regional transmission infrastructure. The recommendations fall into three broad categories: 1. Recommendations on appropriate institutional arrangements and processes for achieving regional consensus on the need for new or expanded transmission infrastructure 2. Recommendations on the process for siting of transmission lines 3. Recommendations on the tools needed to support regional planning, cost allocation, and siting efforts.

Pulse-excited, auto-zeroing multiple channel data transmission system

A multiple channel data transmission system is provided in which signals from a plurality of pulse operated transducers and a corresponding plurality of pulse operated signal processor channels are multiplexed for single channel FM transmission to a receiving station. The transducers and corresponding channel amplifiers are powered by pulsing the dc battery power to these devices to conserve energy and battery size for long-term data transmission from remote or inaccessible locations. Auto zeroing of the signal channel amplifiers to compensate for drift associated with temperature changes, battery decay, component aging, etc., in each channel is accomplished by means of a unique auto zero feature which between signal pulses holds a zero correction voltage on an integrating capacitor coupled to the corresponding channel amplifier output. Pseudo-continuous outputs for each channel are achieved by pulsed sample-and-hold circuits which are updated at the pulsed operation rate. The sample-and-hold outputs are multiplexed into an FM/FM transmitter for transmission to an FM receiver station for demultiplexing and storage in separate channel recorders.

Water has many properties that make it a favorable medium for heat extraction, but it also has serious drawbacks. The use of supercritical CO2 (scCO2) instead of water as heat extraction fluid was suggested by Donald Brown of Los Alamos National Laboratory as a "game changing" alternative that can avoid the problems of aqueous fluids, make heretofore inaccessible energy resources available for human use, and provide ancillary benefits by using and storing CO2.

Stress transmission and isostatic states of non-rigid particulate systems  

E-Print Network (OSTI)

The isostaticity theory for stress transmission in macroscopic planar particulate assemblies is extended here to non-rigid particles. It is shown that, provided that the mean coordination number in $d$ dimensions is $d+1$, macroscopic systems can be mapped onto equivalent assemblies of perectly rigid particles that support the same stress field. The error in the stress field that the compliance introduces for finite systems is shown to decay with size as a power law. This leads to the conclusion that the isostatic state is not limited to infinitely rigid particles both in two and in three dimensions, and paves the way to an application of isostaticity theory to more general systems.

Natural gas transmission and distribution model of the National Energy Modeling System  

SciTech Connect

The Natural Gas Transmission and Distribution Model (NGTDM) is the component of the National Energy Modeling System (NEMS) that is used to represent the domestic natural gas transmission and distribution system. NEMS was developed in the Office of Integrated Analysis and Forecasting of the Energy Information Administration (EIA). NEMS is the third in a series of computer-based, midterm energy modeling systems used since 1974 by the EIA and its predecessor, the Federal Energy Administration, to analyze domestic energy-economy markets and develop projections. From 1982 through 1993, the Intermediate Future Forecasting System (IFFS) was used by the EIA for its analyses, and the Gas Analysis Modeling System (GAMS) was used within IFFS to represent natural gas markets. Prior to 1982, the Midterm Energy Forecasting System (MEFS), also referred to as the Project Independence Evaluation System (PIES), was employed. NEMS was developed to enhance and update EIA`s modeling capability by internally incorporating models of energy markets that had previously been analyzed off-line. In addition, greater structural detail in NEMS permits the analysis of a broader range of energy issues. The time horizon of NEMS is the midterm period (i.e., through 2015). In order to represent the regional differences in energy markets, the component models of NEMS function at regional levels appropriate for the markets represented, with subsequent aggregation/disaggregation to the Census Division level for reporting purposes.

Bang-bang-type optimal constant current control of parallel ac-dc power transmission systems  

SciTech Connect

The transient stability of an ac-dc hybrid system can be improved greatly by controlling the power flow of the dc transmission line. In this study the optimal changeover curve of dc current setting value on the phase plane with a quadratic curve are approximated. The coefficients of this curve are calculated in advance taking into account the loading condition of the power system and hence the proposed control scheme can be used for emergency control of the power system. The main conclusions from this study were that: to facilitate transient stability analysis, the dc transmission line is represented by equivalent load admittances, which vary every second with the operating condition of the transmission line; the action of the speed governor increases the damping coefficient of the power system and reduces the control time which means that the admissible range of the dc current setting value can be reduced by increasing the governor gain; and the optimal change-over curve of the dc current setting value is approximated by a quadratic curve, whose coefficients can be calculated in advance taking into account the loading condition of the power system. The suboptimal changeover curve thus obtained makes it possible to change the setting value of dc current without time delay in emergency condition. While the case of three-phase short-circuit fault was specifically discussed, it is possible to extend the results obtained to the case of successful or unsuccessful reclosing. The proposed method could also be applied to multimachine systems by using equivalent network reduction methods.

Columbia River System Operation Review : Final Environmental Impact Statement, Appendix D: Exhibits.  

DOE Green Energy (OSTI)

The Columbia River and its tributaries are the primary water system in the Pacific Northwest, draining some 219,000 square miles in seven states and another 39,500 square miles in British Columbia. Beginning in the 1930`s, the Columbia River has been significantly modified by construction of 30 major dams on the river and its tributaries, along with dozens of non-Federal projects. Construction and subsequent operation of these water development projects have contributed to eight primary uses of the river system, including navigation, flood control, irrigation, electric power generation, fish migration, fish and wildlife habitat, recreation, and water supply and quality considerations. Increasing stress on the water development of the Columbia River and its tributaries has led primary Federal agencies to undertake intensive analysis and evaluation of the operation of these projects. These agencies are the U.S. Army Corps of Engineers and the Bureau of Reclamation, who operate the large Federal dams on the river, and the Bonneville Power Administration who sells the power generated at the dams. This review, termed the System Operation Review (SOR), has as its ultimate goal to define a strategy for future operation of the major Columbia River projects which effectively considers the needs of all river uses. This volume, Appendix D: Cultural resources appendix, Technical imput includes the following: Development of geomorphology based framework for cultural resources management, Dworshak Reservoir, Idaho; Impact profiles for SOR reservoirs; comments from the following Native American tribes: Burns Paiute Tribe; Coville Confederated Tribes; Confederated Tribes of the Warm Springs Indian Reservation; Confederated Tribes and bands of the Yakama Indian Nation (comments); Nez Perce Tribe; Coeur D`Alene Tribe; Spokane Tribe of Indians; The confederated Tribes of the Umatilla Indian Reservation.

Analysis of operations and cyber security policies for a system of cooperating Flexible Alternating Current Transmission System (FACTS) devices.  

SciTech Connect

Flexible Alternating Current Transmission Systems (FACTS) devices are installed on electric power transmission lines to stabilize and regulate power flow. Power lines protected by FACTS devices can increase power flow and better respond to contingencies. The University of Missouri Rolla (UMR) is currently working on a multi-year project to examine the potential use of multiple FACTS devices distributed over a large power system region in a cooperative arrangement in which the FACTS devices work together to optimize and stabilize the regional power system. The report describes operational and security challenges that need to be addressed to employ FACTS devices in this way and recommends references, processes, technologies, and policies to address these challenges.

Competitive Ratio Analysis of Online Algorithms to Minimize Data Transmission Time in Energy Harvesting Communication System  

E-Print Network (OSTI)

We consider the optimal online packet scheduling problem in a single-user energy harvesting wireless communication system, where energy is harvested from natural renewable sources, making future energy arrivals instants and amounts random in nature. The most general case of arbitrary energy arrivals is considered where neither the future energy arrival instants or amount, nor their distribution is known. The problem considered is to adaptively change the transmission rate according to the causal energy arrival information, such that the time by which all packets are delivered is minimized. We assume that all bits have arrived and are ready at the source before the transmission begins. For a minimization problem, the utility of an online algorithm is tested by finding its competitive ratio or competitiveness that is defined to be the maximum of the ratio of the gain of the online algorithm with the optimal offline algorithm over all input sequences. We derive a lower and upper bound on the competitive ratio of...

STATE RESEARCH, OUTREACH AND TECHNICAL ASSISTANCE TO IMPROVE THE NATIONS TRANSMISSION AND DISTRIBUTION SYSTEMS  

SciTech Connect

The goal of the project 'State Research, Outreach and Technical Assistance to Improve the Nation's Transmission and Distribution Systems' was for the National Association of State Energy Officials (NASEO) to partner with the National Governors Association (NGA) Center for Best Practices, the National Conference of State Legislators (NCSL), and the National Association of Regulatory Utility Commissioners (NARUC) to assist DOE's Office of Electricity Delivery and Energy Reliability (OE) in its effort to modernize and expand America's electric delivery system. NASEO focused on key transmission and distribution issues where coordination between the federal and state governments was critical. Throughout the duration of this program, NASEO engaged in monthly coordination - occasionally more often - with NGA, NCSL and NARUC. NASEO staff and General Counsel Jeff Genzer also had regular face-to-face meetings, phone calls and emails with OE staff to learn from DOE and share information and feedback from the state energy offices on transmission and distribution. To commence work on this project, NASEO met with OE, NGA, NCSL and NARUC in January 2005 and remained committed to regular communications with all involved entities throughout the duration of this project. NASEO provided comments and analysis to the other partners on deliverable reports under this award. This award provided support to NASEO's Energy Production Committee (chaired by Dub Taylor of Texas, followed by Tom Fuller of Wyoming) to plan and host sessions at NASEO's Annual Meeting and Energy Outlook Conferences. Sessions included presentations from state, DOE, national laboratory and private sector experts on transmission, distribution, distributed energy resources, integrating renewable resources into the electricity grid. NASEO disseminated information to its members through emails and its website on transmission and distribution technology and policy. NASEO was an active member of the National Council on Electricity Policy as part of its transmission and distribution work. The National Council on Electricity Policy (National Council) is a venture between NASEO, NARUC, NCSL, National Association of Clean Air Agencies (NACAA) and the National Governors Association (NGA). The National Council also includes several federal members including FERC, DOE, and the U.S. Environment Protection Agency (EPA). NASEO members serve on the policy committee and NASEO General Council Jeff Genzer is a member of the National Council's Executive Committee. NASEO staff participated on regularly scheduled policy committee and executive committee calls and helped to plan agendas and publications for various state decision-makers. Specifically, NASEO organized state energy officials and participating in formulating the agenda for meetings, including the Mid-Atlantic Distributed Generation Workshop in New Jersey in September 2007. NASEO shared the results of these meetings through its website, email communications and direct conversations with state energy officials. NASEO participated as a member of the National Action Plan for Energy Efficiency (NAPEE) Leadership Committee, representing the interests and expertise of the state energy offices. In addition, NASEO was part of the Long-Term Vision Committee. NASEO members also participated in these activities and NASEO has encouraged further efforts of its membership with regards to NAPEE. NASEO has worked to ensure that its membership has the most timely and accurate information about transmission and distribution technology and policy. Its work with other associations has facilitated greater partnerships to enhance activities across the nation and encourage state energy offices to collaborate with public utility commissions, legislatures and executives to improve modern transmission and distribution. NASEO has identified transmission and distribution as a key area for further action.

Magnetohydrodynamic electromagnetic pulse (MHD-EMP) interaction with power transmission and distribution systems  

SciTech Connect

This report discusses the effects of the late-time high-altitude electromagnetic pulse (HEMP) on electrical transmission and distribution (T D) systems. This environment, known as the magnetohydrodynamic electromagnetic pulse (MHD-EMP), is a very slowly varying electric field induced in the earth's surface, similar to the field induced by a geomagnetic storm. It can result in the flow of a quasi-dc current in grounded power lines and in the subsequent magnetic saturation of transformers. This saturation, in turn, causes 6-Hz harmonic distortion and an increase in the reactive power required by generation facilities. This report analyzes and discusses these phenomena. The MHD-EMP environment is briefly discussed, and a simplified form of the earth-induced electric field is developed for use in a parametric study of transmission line responses. Various field coupling models are described, and calculated results for the responses of both transmission- and distribution-class power lines are presented. These calculated responses are compared with measurements of transformer operation under dc excitation to infer the MHD-EMP response of these power system components. It is found that the MHD-EMP environment would have a marked effect on a power system by inducing up to several hundreds of amperes of quasi-dc current on power lines. These currents will cause transformers to saturate which could result in excessive harmonic generation, voltage swings, and voltage suppression. The design of critical facilities which are required to operate during and after MHD-EMP events will have to be modified in order to mitigate the effects of these abnormal power system conditions.

Modeling the System: How Computers are Used in Columbia River Planning.  

DOE Green Energy (OSTI)

This publication describes the three computer models Federal agencies and the Northwest Power Pool use regularly to help plan hydro operations in the Columbia River Basin: HYSSR, HYDROSIM, and HYDREG. It is one of a series of booklets written for participants in the System Operation Review (SOR) being conducted jointly by the US Army Corps of Engineers (Corps), the US Bureau of Reclamation (Reclamation), and theBonneville Power Administration (BPA). A list of the other publications appears on the inside front cover. The SOR is the environmental analysis required to consider changes in Columbia River system operations related contract arrangements. Over the next few years, the agencies will develop a new multiple-use operation for the Columbia River. At the time, the Pacific Northwest Coordination Agreement (PNCA) and other contracts related to the Columbia River Treaty between the United States and Canada will be renegotiated and renewed. Many alternative ways of operating individual projects and the river system as a whole will be considered in the SOR. To analyze how these changes would affect the system's ability to meet its multiple-use goals, various operating scenarios will be thoroughly evaluated. The three computer models, HYSSR, HYDROSIM, and HYDREG, will play an important role in this evaluation.

Biogeochemistry of mercury in a river-reservoir system: impact of an inactive chloralkali plant on the Holston River-Cherokee Reservoir, Virginia and Tennessee  

SciTech Connect

Elevated mercury concentrations in fish species from the North Fork of the Holston River were observed in the early 1970's. The source of the mercury was a chloralkali plant which had ceased operation in 1972. Mercury continues to be released to the river from two large (approx. 40-ha) waste disposal ponds at the plant site. This report presents results of a study of the emission of mercury to the environment from the abandoned waste ponds and of the distribution of mercury in water, sediment, and biota of the Holston River-Cherokee Reservoir System in Virginia and eastern Tennessee.

Closed loop chemical systems for energy storage and transmission (chemical heat pipe). Final report  

DOE Green Energy (OSTI)

The work documents the anlaysis of closed loop chemical systems for energy storage and transmission, commonly referred to as the Chemical Heat Pipe (CHP). Among the various chemical reaction systems and sources investigated, the two best systems were determined to be the high temperature methane/steam reforming reaction (HTCHP) coupled to a Very High Temperature Gas Cooled Reactor (VHTR) and the lower temperature, cyclohexane dehydrogenation reaction (LTCHP) coupled to existing sources such as coal or light water reactors. Solar and other developing technologies can best be coupled to the LTCHP. The preliminary economic and technical analyses show that both systems could transport heat at an incremental cost of approximately $1.50/GJ/160 km (in excess of the primary heat cost of $2.50/GJ), at system efficiencies above 80%. Solar heat can be transported at an incremental cost of $3/GJ/160 km. The use of the mixed feed evaporator concept developed in this work contributes significantly to reducing the transportation cost and increasing the efficiency of the system. The LTCHP shows the most promise of the two systems if the technical feasibility of the cyclic closed loop chemical reaction system can be established. An experimental program for establishing this feasibility is recommended. Since the VHTR is several years away from commercial demonstration and the HTCHP chemical technology is well developed, future HTCHP programs should be aimed at VHTR and interface problems.

On adaptive transmission, signal detection and channel estimation for multiple antenna systems  

E-Print Network (OSTI)

This research concerns analysis of system capacity, development of adaptive transmission schemes with known channel state information at the transmitter (CSIT) and design of new signal detection and channel estimation schemes with low complexity in some multiple antenna systems. We first analyze the sum-rate capacity of the downlink of a cellular system with multiple transmit antennas and multiple receive antennas assuming perfect CSIT. We evaluate the ergodic sum-rate capacity and show how the sum-rate capacity increases as the number of users and the number of receive antennas increases. We develop upper and lower bounds on the sum-rate capacity and study various adaptive MIMO schemes to achieve, or approach, the sum-rate capacity. Next, we study the minimum outage probability transmission schemes in a multiple-input-single-output (MISO) flat fading channel assuming partial CSIT. Considering two special cases: the mean feedback and the covariance feedback, we derive the optimum spatial transmission directions and show that the associated optimum power allocation scheme, which minimizes the outage probability, is closely related to the target rate and the accuracy of the CSIT. Since CSIT is obtained at the cost of feedback bandwidth, we also consider optimal allocation of bandwidth between the data channel and the feedback channel in order to maximize the average throughput of the data channel in MISO, flat fading, frequency division duplex (FDD) systems. We show that beamforming based on feedback CSI can achieve an average rate larger than the capacity without CSIT under a wide range of mobility conditions. We next study a SAGE-aided List-BLAST detection scheme for MIMO systems which can achieve performance close to that of the maximum-likelihood detector with low complexity. Finally, we apply the EM and SAGE algorithms in channel estimation for OFDM systems with multiple transmit antennas and compare them with a recently proposed least-squares based estimation algorithm. The EM and SAGE algorithms partition the problem of estimating a multi-input channel into independent channel estimation for each transmit-receive antenna pair, therefore avoiding the matrix inversion encountered in the joint least-squares estimation.

UNDERSTANDING METHANE EMISSIONS SOURCES AND VIABLE MITIGATION MEASURES IN THE NATURAL GAS TRANSMISSION SYSTEMS: RUSSIAN AND U.S. EXPERIENCE  

Science Conference Proceedings (OSTI)

This article will compare the natural gas transmission systems in the U.S. and Russia and review experience with methane mitigation technologies in the two countries. Russia and the United States (U.S.) are the world's largest consumers and producers of natural gas, and consequently, have some of the largest natural gas infrastructure. This paper compares the natural gas transmission systems in Russia and the U.S., their methane emissions and experiences in implementing methane mitigation technologies. Given the scale of the two systems, many international oil and natural gas companies have expressed interest in better understanding the methane emission volumes and trends as well as the methane mitigation options. This paper compares the two transmission systems and documents experiences in Russia and the U.S. in implementing technologies and programs for methane mitigation. The systems are inherently different. For instance, while the U.S. natural gas transmission system is represented by many companies, which operate pipelines with various characteristics, in Russia predominately one company, Gazprom, operates the gas transmission system. However, companies in both countries found that reducing methane emissions can be feasible and profitable. Examples of technologies in use include replacing wet seals with dry seals, implementing Directed Inspection and Maintenance (DI&M) programs, performing pipeline pump-down, applying composite wrap for non-leaking pipeline defects and installing low-bleed pneumatics. The research methodology for this paper involved a review of information on methane emissions trends and mitigation measures, analytical and statistical data collection; accumulation and analysis of operational data on compressor seals and other emission sources; and analysis of technologies used in both countries to mitigate methane emissions in the transmission sector. Operators of natural gas transmission systems have many options to reduce natural gas losses. Depending on the value of gas, simple, low-cost measures, such as adjusting leaking equipment components, or larger-scale measures, such as installing dry seals on compressors, can be applied.

Model documentation: Natural Gas Transmission and Distribution Model of the National Energy Modeling System; Volume 1  

SciTech Connect

The Natural Gas Transmission and Distribution Model (NGTDM) is a component of the National Energy Modeling System (NEMS) used to represent the domestic natural gas transmission and distribution system. NEMS is the third in a series of computer-based, midterm energy modeling systems used since 1974 by the Energy Information Administration (EIA) and its predecessor, the Federal Energy Administration, to analyze domestic energy-economy markets and develop projections. This report documents the archived version of NGTDM that was used to produce the natural gas forecasts used in support of the Annual Energy Outlook 1994, DOE/EIA-0383(94). The purpose of this report is to provide a reference document for model analysts, users, and the public that defines the objectives of the model, describes its basic design, provides detail on the methodology employed, and describes the model inputs, outputs, and key assumptions. It is intended to fulfill the legal obligation of the EIA to provide adequate documentation in support of its models (Public Law 94-385, Section 57.b.2). This report represents Volume 1 of a two-volume set. (Volume 2 will report on model performance, detailing convergence criteria and properties, results of sensitivity testing, comparison of model outputs with the literature and/or other model results, and major unresolved issues.) Subsequent chapters of this report provide: (1) an overview of the NGTDM (Chapter 2); (2) a description of the interface between the National Energy Modeling System (NEMS) and the NGTDM (Chapter 3); (3) an overview of the solution methodology of the NGTDM (Chapter 4); (4) the solution methodology for the Annual Flow Module (Chapter 5); (5) the solution methodology for the Distributor Tariff Module (Chapter 6); (6) the solution methodology for the Capacity Expansion Module (Chapter 7); (7) the solution methodology for the Pipeline Tariff Module (Chapter 8); and (8) a description of model assumptions, inputs, and outputs (Chapter 9).

Daily/Hourly Hydrosystem Operation : How the Columbia River System Responds to Short-Term Needs.  

SciTech Connect

The System Operation Review, being conducted by the Bonneville Power Administration, the US Army Corps of Engineers, and the US Bureau of Reclamation, is analyzing current and potential future operations of the Columbia River System. One goal of the System Operations Review is to develop a new System Operation Strategy. The strategy will be designed to balance the many regionally and nationally important uses of the Columbia River system. Short-term operations address the dynamics that affect the Northwest hydro system and its multiple uses. Demands for electrical power and natural streamflows change constantly and thus are not precisely predictable. Other uses of the hydro system have constantly changing needs, too, many of which can interfere with other uses. Project operators must address various river needs, physical limitations, weather, and streamflow conditions while maintaining the stability of the electric system and keeping your lights on. It takes staffing around the clock to manage the hour-to-hour changes that occur and the challenges that face project operators all the time.

Probabilistic Approach to Quantifying the Contribution of Variable Generation and Transmission to System Reliability: Preprint  

DOE Green Energy (OSTI)

The increasing electrical load served by variable generation (VG), such as wind and solar energy, in the United States and many other countries has stimulated an interesting line of research to better quantify the capacity value of these resources. Methods applied traditionally to thermal units based on their average outage rates do not apply to VG because of their uncertain and non-dispatchable nature. The North American Electric Reliability Corporation's Integration of Variable Generation Task Force recently released a report that highlighted the need to develop and benchmark underlying loss-of-load expectation and related metrics that reasonably and fairly calculate the contribution to planning reserves, or capacity value, of solar and wind power. As the fraction of generation coming from VG becomes more significant, their estimated capacity value will have a larger impact on system planning. In this paper, we provide a method to include VG in traditional probabilistic-based adequacy methods. This method has been implemented in the Renewable Energy Probabilistic Resource Assessment tool developed at the National Renewable Energy Laboratory. Through an example based on the U.S. Western Interconnection, this method is applied to assess the effect that transmission can have on resource adequacy. We also analyze the interactions between available transmission and capacity value for VG.

Supplement Analysis for the Transmission System Vegetation Management Program FEIS DOE/EIS-0285/SA-08  

Science Conference Proceedings (OSTI)

Clearing C-trees along the south side of the right-of-way. This project meets the standards and guidelines for the Transmission System Vegetation Management Program Final Environmental Impact Statement (FEIS) and Record of Decision (ROD). The project involves controlling all tall growing trees (C-Trees) within the right-of-way. All work is to be done on the south side of centerline. Target vegetation is the tall growing Firs along the edge of the ROW, all of which is located within the back yards of the property owners along the right-of-way. The density of vegetation is low and consists of C-Trees located within backyards, with the branches growing towards the lines. Due to lack of access and past verbal agreements with the landowners, permission/agreement has been difficult to obtain from the property owners. Permission has now been obtained to remove the C-Trees within their back yards which, will soon be a hazard to our transmission line facility. We are working with the landowners to get them to plant low growing scrubs and ornamentals within the right-of-way and adjacent to the right-of-way. A follow up herbicide treatment is not planned because the trees being cut will not re-sprout. This right-of-way or project area is on a three to four year maintenance schedule. Little or no treatment should be required in the immediate future.

30 MJ superconducting magnetic energy storage performance on the Bonneville Power Administration utility transmission system*  

DOE Green Energy (OSTI)

The 30 MJ, 10 MW superconducting magnetic energy storage (SMES) system was devised to interact in the Western U.S. Power System as an alternate means to damp unstable oscillations at 0.35 Hz on the Pacific HVAC Intertie. The SMES unit was installed at the Tacoma Substation of the Bonneville Power Administration (BPA). The operating limits of the 30 MJ SMES unit were established, and different means of controlling real and reactive power were tested. The unit can follow a sinusoidal power demand signal with an amplitude of up to 8.6 MW with the converter working in a 12 pulse mode. When the converter operates in the constant VAR mode, a time varying real power demand signal of up to 5 MW can be met. Experiments showed that the Pacific AC Intertie has current and reactive power variations of the same frequency as the modulating frequency of the SMES device. Endurance tests were run to assess the reliability of the SMES subsystems with a narrow band noise input, which is characteristic of the modulation signal for stabilizer operation. In this mode, the energy of the power spectrum is not concentrated at one frequency to avoid exciting a resonance frequency of the ac transmission system. During the endurance tests, parameters of the ac power system were determined. Accurate power system data are necessary for tuning the control algorithm so that the SMES unit can operate in the closed loop stabilizer mode.

DOE Green Energy (OSTI)

The goal of the Coordinated Information System (CIS) is to develop and provide an efficient system for obtaining and exchanging information needed to plan, monitor, and evaluate the protection, mitigation, and enhancement of anadromous salmonid populations in the Columbia River Basin. Since its inception, the development of CIS consisted of building a team of people representing agencies that manage fisheries and natural resources in the Columbia River Basin, and developing an administrative framework to maintain, enhance, and distribute anadromous salmonid information to public and private resource managers and researchers; assembling biological information on anadromous salmonids that could be used to evaluate system wide population dynamics; and developing the technology to deliver the information provided by CIS. This report summarizes the services that are now available to information users, and describes the administration through which services are delivered. Services and features that will be further developed during the 1994 fiscal year are also described.

Columbia River System Operation Review : Final Environmental Impact Statement, Appendix R: Pacific Northwest Coordination agreement (PNCA).  

DOE Green Energy (OSTI)

Currently, the Federal government coordinates the planning and operation of the Federal Columbia River Power System (FCRPS) with projects owned and operated by the region`s non-Federal hydrogenerating utilities pursuant to the Pacific North-west Coordination Agreement (PNCA). The Bureau of Reclamation (Reclamation), the Corps of Engineers (Corps), and the Bonneville Power Administration (BPA) are parties to the PNCA on behalf of the government of the United States. The PNCA is a complex agreement that provides an opportunity for the region`s power producers to maximize the power system`s reliability and economy while meeting their multiple-use objectives. The PNCA does not dictate the operation of the resources it coordinates. It is essentially an accounting mechanism that exchanges the power produced among the parties in order to improve the reliability of the system and reduce regional power costs. Project owners retain complete autonomy to operate as needed to meet their multiple-use requirements. The PNCA was executed in 1964 as an important component of regional plans to maximize the Northwest`s hydro resource capability. Maximization also included the development of storage projects on the Columbia River in Canada pursuant to the terms of the 1964 Columbia River Treaty. Because of the link between power coordination and Treaty issues, the current parties to the PNCA, currently are contemplating entering into a replacement or renewed power coordination agreement. Because the power coordination agreement is a consensual arrangement, its ultimate provisions must be acceptable to all of its signatories. This Appendix R to the Final Environmental Impact Statement of the Columbia River System is a presentation of the Pacific North-west Coordination Agreement.

Preliminary subsurface hydrologic considerations: Columbia River Plateau Physiographic Province. Assessment of effectiveness of geologic isolation systems  

SciTech Connect

This report contains a discussion of the hydrologic conditions of the Columbia River Plateau physiographic province. The Columbia River Plateau is underlain by a thick basalt sequence. The Columbia River basalt sequence contains both basalt flows and sedimentary interbeds. These sedimentary interbeds, which are layers of sedimentary rock between lava flows, are the main aquifer zones in the basalt sequence. Permeable interflow zones, involving the permeable top and/or rubble bottom of a flow, are also water-transmitting zones. A number of stratigraphic units are present in the Pasco Basin, which is in the central part of the Columbia River Plateau. At a conceptual level, the stratigraphic sequence from the surface downward can be separated into four hydrostratigraphic systems. These are: (1) the unsaturated zone, (2) the unconfined aquifer, (3) the uppermost confined aquifers, and (4) the lower Yakima basalt hydrologic sequence. A conceptual layered earth model (LEM) has been developed. The LEM represents the major types of porous media (LEM units) that may be encountered at a number of places on the Columbia Plateau, and specifically in the Pasco Basin. The conceptual LEM is not representative of the actual three-dimensional hydrostratigraphic sequence and hydrologic conditions existing at any specific site within the Columbia Plateau physiographic province. However, the LEM may be useful for gaining a better understanding of how the hydrologic regime may change as a result of disruptive events that may interact with a waste repository in geologic media.

Individual Dose Calculations with Use of the Revised Techa River Dosimetry System TRDS-2009D  

SciTech Connect

An updated deterministic version of the Techa River Dosimetry System (TRDS-2009D) has been developed to estimate individual doses from external exposure and intake of radionuclides for residents living on the Techa River contaminated as a result of radioactive releases from the Mayak plutonium facility in 19491956. The TRDS-2009D is designed as a flexible system that uses, depending on the input data for an individual, various elements of system databases to provide the dosimetric variables requested by the user. Several phases are included in the computation schedule. The first phase includes calculations with use of a common protocol for all cohort members based on village-average-intake functions and external dose rates; individual data on age, gender and history of residence are included in the first phase. This phase results in dose estimates similar to those obtained with system TRDS-2000 used previously to derive risks of health effects in the Techa River Cohort. The second phase includes refinement of individual internal doses for those persons who have had body-burden measurements or exposure parameters specific to the household where he/she lived on the Techa River. The third phase includes summation of individual doses from environmental exposure and from radiological examinations. The results of TRDS-2009D dose calculations have demonstrated for the ETRC members on average a moderate increase in RBM dose estimates (34%) and a minor increase (5%) in estimates of stomach dose. The calculations for the members of the ETROC indicated similar small changes for stomach, but significant increase in RBM doses (400%). Individual-dose assessments performed with use of TRDS-2009D have been provided to epidemiologists for exploratory risk analysis in the ETRC and ETROC. These data provide an opportunity to evaluate the possible impact on radiogenic risk of such factors as confounding exposure (environmental and medical), changes in the Techa River source-term data and the change of the approach to individual internal dose estimation (90Sr-body burden measurements and family correlations vs. village averages). Our further plan is to upgrade the TRDS-2009D and to complete a stochastic version of the dosimetry system.

Columbia River Coordinated Information System (CIS); Phase II Cooperative Agreement, 1992 Technical Report.  

DOE Green Energy (OSTI)

Anadromous salmon in the Columbia River Basin are presently far below historic level of production, due to the impacts of development in the basin. To halt the downward trend in production and ultimately increase returns, the Northwest Power Planning Council developed the Columbia River Basin Fish and Wildlife Program. The Program outlines a coordinated plan for restoring anadromous salmonid runs to the basin. The goals and objectives outlined in the Program require addressing a complex set of problems that encompass a broad range of social, political, economic and biological issues. Resolution of these problems will require the efforts of a number of federal, state, and tribal agencies that have regulatory authority over activities that either directly or indirectly affect anadromous salmonids in the basin. Resource managers have realized the need for coordination in these efforts. The Coordinated Information System is designed to share information critical to Program development and evaluation efficiently among the numerous participants in the restoration process.

INTELLIGENT COMPUTING SYSTEM FOR RESERVOIR ANALYSIS AND RISK ASSESSMENT OF THE RED RIVER FORMATION  

SciTech Connect

Integrated software has been written that comprises the tool kit for the Intelligent Computing System (ICS). The software tools in ICS have been developed for characterization of reservoir properties and evaluation of hydrocarbon potential using a combination of inter-disciplinary data sources such as geophysical, geologic and engineering variables. The ICS tools provide a means for logical and consistent reservoir characterization and oil reserve estimates. The tools can be broadly characterized as (1) clustering tools, (2) neural solvers, (3) multiple-linear regression, (4) entrapment-potential calculator and (5) file utility tools. ICS tools are extremely flexible in their approach and use, and applicable to most geologic settings. The tools are primarily designed to correlate relationships between seismic information and engineering and geologic data obtained from wells, and to convert or translate seismic information into engineering and geologic terms or units. It is also possible to apply ICS in a simple framework that may include reservoir characterization using only engineering, seismic, or geologic data in the analysis. ICS tools were developed and tested using geophysical, geologic and engineering data obtained from an exploitation and development project involving the Red River Formation in Bowman County, North Dakota and Harding County, South Dakota. Data obtained from 3D seismic surveys, and 2D seismic lines encompassing nine prospective field areas were used in the analysis. The geologic setting of the Red River Formation in Bowman and Harding counties is that of a shallow-shelf, carbonate system. Present-day depth of the Red River formation is approximately 8000 to 10,000 ft below ground surface. This report summarizes production results from well demonstration activity, results of reservoir characterization of the Red River Formation at demonstration sites, descriptions of ICS tools and strategies for their application.

Number of lightning discharges causing damage to lightning arrester cables for aerial transmission lines in power systems  

SciTech Connect

Damage by lightning discharges to lightning arrester cables for 110-175 kV aerial transmission lines is analyzed using data from power systems on incidents with aerial transmission lines over a ten year operating period (1997-2006). It is found that failures of lightning arrester cables occur when a tensile force acts on a cable heated to the melting point by a lightning current. The lightning currents required to heat a cable to this extent are greater for larger cable cross sections. The probability that a lightning discharge will develop decreases as the amplitude of the lightning current increases, which greatly reduces the number of lightning discharges which damage TK-70 cables compared to TK-50 cables. In order to increase the reliability of lightning arrester cables for 110 kV aerial transmission lines, TK-70 cables should be used in place of TK-50 cables. The number of lightning discharges per year which damage lightning arrester cables is lowered when the density of aerial transmission lines is reduced within the territory of electrical power systems. An approximate relationship between these two parameters is obtained.

Energy-Efficient Delay-Constrained Transmission and Sensing for Cognitive Radio Systems  

E-Print Network (OSTI)

In this work we study energy-efficient transmission for Cognitive Radio (CR) which opportunistically operates on Primary User's (PU's) channel through spectrum sensing. Spectrum sensing and compulsory idling (for incumbent protection) introduce energy-overheads for Secondary User's (SU's) operations, and thus an appropriate balance between energy consumption in data transmission and energy-overheads is required. We formulate this problem as a discrete-time Markov Decision Process (MDP) in which the SU aims at minimizing its average cost (including both energy consumption and delay cost) to finish a target traffic payload through an appropriate rate allocation. Based on Certainty Equivalent Control, we propose a low-complexity rate-adaptation policy that achieves comparable performance as the optimal policy. With the low-complexity policy, we quantify the impact of energy-overheads (including the power consumption for spectrum sensing and compulsory idling) on the SU transmission strategy. Specifically, the SU...

Solar energy system performance evaluation - final report for Honeywell OTS 45, Salt River Project, Phoenix, Arizona  

DOE Green Energy (OSTI)

This report describes the operation and technical performance of the Solar Operational Test Site (OTS 45) at Salt River Project in Phoenix, Arizona, based on the analysis of data collected between April 1981 and March 31, 1982. The following topics are discussed: system description, performance assessment, operating energy, energy savings, system maintenance, and conclusions. The solar energy system at OTS 45 is a hydronic heating and cooling system consisting of 8208 square feet of liquid-cooled flat-plate collectors; a 2500-gallon thermal storage tank; two 25-ton capacity organic Rankine-cycle-engine-assisted water chillers; a forced-draft cooling tower; and associated piping, pumps, valves, controls and heat rejection equipment. The solar system has eight basic modes of operation and several combination modes. The system operation is controlled automatically by a Honeywell-designed microprocessor-based control system, which also provides diagnostics. Based on the instrumented test data monitored and collected during the 8 months of the Operational Test Period, the solar system collected 1143 MMBtu of thermal energy of the total incident solar energy of 3440 MMBtu and provided 241 MMBtu for cooling and 64 MMBtu for heating. The projected net annual electrical energy savings due to the solar system was approximately 40,000 kWh(e).

Systems Engineering in the Development and Implementation of the Savannah River Site Transuranic Waste Disposition Program  

SciTech Connect

The use of systems engineering facilitated the strategic planning and implementation of the Savannah River Site (SRS) transuranic waste disposal program. This application represented the first SRS use of systems engineering in the pre-program planning stages during the development of a comprehensive strategic plan for the disposal of transuranic waste at the Department of Energy Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico. The use of systems engineering focused the efforts of the technical experts to devise a three initiative plan for the disposal of transuranic waste where previous efforts failed. Continued application of systems engineering facilitated the further development and implementation of the first initiative outlined in the strategic plan, i.e., set-up the program and process to begin to characterize and ship waste to the WIPP.This application of systems engineering to the transuranic waste program represented the first opportunity at the SRS for a comprehensive usage of systems engineering at all program levels. The application was initiated at the earliest possible point in the program development, i.e., strategic planning, and successively was used in detailed development and implementation of the program. Systems engineering successfully focused efforts to produce a comprehensive plan for the disposal of SRS transuranic waste at the WIPP, and facilitated development of the SRS capability and infrastructure to characterize, certify, and ship waste.

Automated manual transmission controller  

DOE Patents (OSTI)

A powertrain system for a hybrid vehicle. The hybrid vehicle includes a heat engine, such as a diesel engine, and an electric machine, which operates as both an electric motor and an alternator, to power the vehicle. The hybrid vehicle also includes a manual-style transmission configured to operate as an automatic transmission from the perspective of the driver. The engine and the electric machine drive an input shaft which in turn drives an output shaft of the transmission. In addition to driving the transmission, the electric machine regulates the speed of the input shaft in order to synchronize the input shaft during either an upshift or downshift of the transmission by either decreasing or increasing the speed of the input shaft. When decreasing the speed of the input shaft, the electric motor functions as an alternator to produce electrical energy which may be stored by a storage device. Operation of the transmission is controlled by a transmission controller which receives input signals and generates output signals to control shift and clutch motors to effect smooth launch, upshift shifts, and downshifts of the transmission, so that the transmission functions substantially as an automatic transmission from the perspective of the driver, while internally substantially functioning as a manual transmission.

INTELLIGENT COMPUTING SYSTEM FOR RESERVOIR ANALYSIS AND RISK ASSESSMENT OF THE RED RIVER FORMATION  

SciTech Connect

Integrated software has been written that comprises the tool kit for the Intelligent Computing System (ICS). Luff Exploration Company is applying these tools for analysis of carbonate reservoirs in the southern Williston Basin. The integrated software programs are designed to be used by small team consisting of an engineer, geologist and geophysicist. The software tools are flexible and robust, allowing application in many environments for hydrocarbon reservoirs. Keystone elements of the software tools include clustering and neural-network techniques. The tools are used to transform seismic attribute data to reservoir characteristics such as storage (phi-h), probable oil-water contacts, structural depths and structural growth history. When these reservoir characteristics are combined with neural network or fuzzy logic solvers, they can provide a more complete description of the reservoir. This leads to better estimates of hydrocarbons in place, areal limits and potential for infill or step-out drilling. These tools were developed and tested using seismic, geologic and well data from the Red River Play in Bowman County, North Dakota and Harding County, South Dakota. The geologic setting for the Red River Formation is shallow-shelf carbonate at a depth from 8000 to 10,000 ft.

Detecting internal corrosion of natural gas transmission pipelines: field tests of probes and systems for real-time corrosion measurement  

Science Conference Proceedings (OSTI)

A field study was conducted to evaluate the use of automated, multi-technique electrochemical corrosion-rate monitoring devices and probes for detecting corrosion in environments similar to those found in natural gas transmission pipelines. It involved measurement of real-time corrosion signals from operating pipelines. Results and interpretation were reported from four different field test locations. Standard flush-mount and custom flange probes were used in four different environments at a gas-gathering site and one environment but two different probe orientations at a natural gas site. These sites were selected to represent normal and upset conditions common in gas transmission pipelines. The environments consisted of two different levels of humidified natural gas, liquid hydrocarbon, and water from natural gas. Probe locations included the 6 and 12 o?clock positions of a natural gas pipeline carrying 2-phase gas/liquid flow. The probe data was monitored using completely remote solar powered systems that provided real-time data transmission via wireless back to a pipeline control station. Data are also presented comparing the ECR probe data to that for coupons used to determine corrosion rate and to detect the presence of microbiologically influenced corrosion (MIC).

Developed from the quantum bath based effective Hamiltonian method for single mode harmonic oscillator, the approach we presented in this article is a microscopic theory integrating quantum fluctuation-dissipation relation. To qualitatively check the condition under which the TLR can behave as a quantum object we study the classical-quantum boundary characterized by the standard quantum limit.

Overhead electric power transmission line jumpering system for bundles of five or more subconductors  

DOE Patents (OSTI)

Jumpering of electric power transmission lines at a dead end tower. Two transmission line conductor bundles each contain five or more spaced apart subconductors (5) arranged in the shape of a cylinder having a circular cross section. The ends of each bundle of subconductors are attached with insulators to a dead end tower (1). Jumpering allows the electric current to flow between the two bundles of subconductors using jumper buses, internal jumper conductors, and external jumper conductors. One or more current collecting jumper buses (37) are located inside each bundle of subconductors with each jumper bus being attached to the end of a subconductor. Small-diameter internal jumper conductors (33) are located in the inherently electrically shielded area inside each bundle of subconductors with each subconductor (except ones having an attached jumper bus) having one internal jumper conductor connected between that subconductor's end and a jumper bus. Large-diameter external jumper conductors (9) are located outside each bundle of subconductors with one or more external jumper conductors being connected between the jumper buses in one bundle of subconductors and the jumper buses in the other bundle.

Nanoparticle model systems on planar supports form a versatile platform for studying morphological and compositional changes of catalysts due to exposure to realistic reaction conditions. We review examples from our work on iron and cobalt catalysts, which can undergo significant rearrangement in the reactive environment of the Fischer-Tropsch synthesis. The use of specially designed, silicon based supports with thin film SiO{sub 2} enables the application of transmission electron microscopy, which has furnished important insight into e.g. the mechanisms of catalyst regeneration.

Columbia River System Operation Review : Final Environmental Impact Statement, Appendix F: Irrigation, Municipal and Industrial/Water Supply.  

DOE Green Energy (OSTI)

Since the 1930`s, the Columbia River has been harnessed for the benefit of the Northwest and the nation. Federal agencies have built 30 major dams on the river and its tributaries. Dozens of non-Federal projects have been developed as well. The dams provide flood control, irrigation, navigation, hydro-electric power generation, recreation, fish and wildlife, and streamflows for wildlife, anadromous fish, resident fish, and water quality. This is Appendix F of the Environmental Impact Statement for the Columbia River System, focusing on irrigation issues and concerns arrising from the Irrigation and Mitigation of impacts (M&I) working Group of the SOR process. Major subheadings include the following: Scope and process of irrigation/M&I studies; Irrigation/M&I in the Columbia Basin Today including overview, irrigated acreage and water rights, Irrigation and M&I issues basin-wide and at specific locations; and the analysis of impacts and alternative for the Environmental Impact Statement.

FOR ELECTRIC POWER TRANSMISSION  

E-Print Network (OSTI)

A contract network extends the concept of a contract path to address the problem of loop flow and congestion in electric power transmission systems. A contract network option provides a well defined, internally consistent framework for assigning long-term capacity rights to a complicated electric transmission network. The contract network respects the special conditions induced by Kirchoff's Laws; accommodates thermal, voltage and contingency constraints on transmission capacity; and can be adopted without disturbing existing methods for achieving an economic power dispatch subject to these constraints. By design, a contract network would maintain short-run efficiency through optimal spot price determination of transmission prices. Through payment of congestion rentals, the contract network makes a long-term capacityright holder indifferent between delivery of the power or receipt of payments in a settlement system. And the contract network framework can support allocation of transmission capacity rights through a competitive bidding process. CONTRACT NETWORKS

A Review of the . . . : The Possible Roles of TSOs in Monitoring for Market Power Issues in Congested Transmission Systems  

E-Print Network (OSTI)

The paper surveys the literature and publicly available information on market power monitoring in electricity wholesale markets. After briefly reviewing definitions, strategies and methods of mitigating market power we examine the various methods of detecting market power that have been employed by academics and market monitors/regulators. These techniques include structural and behavioural indices and analysis as well as various simulation approaches. The applications of these tools range from spot market mitigation and congestion management through to long-term market design assessment and merger decisions. Various market-power monitoring units already track market behaviour and produce indices. Our survey shows that these units collect a large amount of data from various market participants and we identify the crucial role of the transmission system operators with their access to dispatch and system information. Easily accessible and comprehensive data supports effective market power monitoring and facilitates market design evaluation. The discretion required for effective market monitoring is facilitated by institutional independence.

Columbia River Coordinated Information System (CIS); Data Catalog, 1992 Technical Report.  

DOE Green Energy (OSTI)

The Columbia River Coordinated Information system (CIS) Project started in 1989 to address regional data sharing. Coordinated exchange and dissemination of any data must begin with dissemination of information about those data, such as: what is available; where the data are stored; what form they exist in; who to contact for further information or access to these data. In Phase II of this Project (1991), a Data Catalog describing the contents of regional datasets and less formal data collections useful for system monitoring and evaluation projects was built to improve awareness of their existence. Formal datasets are described in a `Dataset Directory,` while collections of data are Used to those that collect such information in the `Data Item Directory.` The Data Catalog will serve regional workers as a useful reference which centralizes the institutional knowledge of many data contacts into a single source. Recommendations for improvement of the Catalog during Phase III of this Project include addressing gaps in coverage, establishing an annual maintenance schedule, and loading the contents into a PC-based electronic database for easier searching and cross-referencing.

Laboratory Evaluation of an Electrochemical Noise System for Detection of Localized and General Corrosion of Natural Gas Transmission Pipelines  

SciTech Connect

Gas transmission pipelines are susceptible to both internal (gas side) and external (soil side) corrosion attack. Internal corrosion is caused by the presence of salt laden moisture, CO{sub 2}, H{sub 2}S, and perhaps O{sub 2} in the natural gas. Internal corrosion usually manifests itself as general corrosion. However, the presence of chlorides in entrained water also can lead to pitting corrosion damage. The electrochemical noise technique can differentiate general from localized corrosion and provide estimates of corrosion rates without external perturbation of the corroding system. It is increasingly being applied to field and industrial installations for in situ corrosion monitoring. It has been used here to determine its suitability for monitoring internal and external corrosion damage on gas transmission pipelines. Corrosion measurements were made in three types of environments: (1) aqueous solutions typical of those found within gas pipelines in equilibrium with th e corrosive components of natural gas; (2) biologically-active soils typical of wetlands; and (3) a simulated, unpressurized, internal gas/liquid gas pipeline environment. Multiple sensor designs were evaluated in the simulated pipe environment. Gravimetric measurements were conducted in parallel with the electrochemical noise measurements to validate the results.

Bonneville Power Administration Transmission System Vegetation Management Program - Final Environmental Impact Statement  

SciTech Connect

Bonneville is responsible for maintaining a network of 24,000 kilometers (km) or 15,000 miles (mi.) of electric transmission lines and 350 substations in a region of diverse vegetation. This vegetation can interfere with electric power flow, pose safety problems for us and the public, and interfere with our ability to maintain these facilities. We need to (1) keep vegetation away from our electric facilities; (2) increase our program efficiency and consistency; (3) review herbicide use (under increased public scrutiny); and (4) maximize the range of tools we can use while minimizing environmental impact (Integrated Vegetation Management). This Final Environmental Impact Statement (FEIS) establishes Planning Steps for managing vegetation for specific projects (to be tiered to this Environmental Impact Statement (EIS)). In addition to No Action (current practice), alternatives are presented for Rights-of-way, Electric Yards, and Non-electric Facilities (landscaping, work yards). Four vegetation control methods are analyzed manual, mechanical, herbicide, and biological. Also evaluated are 23 herbicide active ingredients and 4 herbicide application techniques (spot, localized, broadcast, and aerial). For rights-of-way, we consider three sets of alternatives: alternative management approaches (time-driven or establishing low-growing plant communities); alternative method packages; and, if herbicides are in a methods package, alternative vegetation selections (noxious weeds, deciduous, or any vegetation). For electric yards, one herbicide-use alternative is considered. For non-electric facilities, two method package alternatives are considered. For rights-of-way, the environmentally preferred alternative(s) would use manual, mechanical, and biological control methods, as well as spot and localized herbicide applications for noxious and deciduous plant species; the BPA-preferred alternative(s) would add broadcast and aerial herbicide applications, and would use herbicides on any vegetation. Both would favor a management approach that fosters low-growing plant communities.

Tests with a line-commutated converter as a variable inductive load on the Bonneville Power Administration transmission system  

DOE Green Energy (OSTI)

A twelve-pulse, line-commutated converter, with a steady-state rating of 2.5 kV and 5.5 kA, formerly used for charging and discharging a superconducting magnet, was reconfigured as a static reactive power load. Tests staged at the Tacoma, WA, substation of the Bonneville Power Administration (BPA) revealed that the converter could be used as a variable inductive load, provided a stable current controller was installed. The unit was modulated as a variable VAR load following a sinusoidal VAR demand signal with an amplitude up to 14.8 MVAR. The total losses at maximum VAR output were 370 kW. This paper explains the necessary modifications of the converter to operate as a variable reactive load. Measured current waveshapes are analyzed. The effects of such a load on the BPA transmission system are presented.

30-MJ superconducting magnetic energy storage system for electric utility transmission stabilization  

SciTech Connect

A superconducting magnetic energy storage (SMES) system has been built to damp power oscillations on the Western U.S. Power System, particularly on the Pacific AC Intertie that is used to transmit power from the Northwest to southern California. The 30-MJ superconducting inductor that stores energy for this purpose is contained in a nonconducting dewar and is supported by a helium refrigerator and a gas-handling system mounted on trailers. Energy flows in and out of the inductor at frequencies from 0.1 to 1.0 Hz with power amplitudes up to 11 MW. The principal oscillation to be damped has a characteristic frequency of 0.35 Hz. The superconducting coil maximum current is 5 kA with terminal voltages up to 2.2 kV. The coil interfaces with the Bonneville Power Administration 13.8-kV bus at the Tacoma Substation through a converter and transformers. The system can be operated with the converter either in parallel-bridge mode or for constant VAR control with the bridges in buck-boost mode. The program for the design, fabrication, installation, and the preliminary experimental operation of the system is reviewed.

Kootenai River Nutrient Dosing System and N-P Consumption: Year 2008.  

DOE Green Energy (OSTI)

In early 2006 we designed and built low energy consumption, pump-operated system, for dosing of the liquid nutrient in the summer 2006 season. This operated successfully, and the system was used again during the 2007 and 2008 seasons for dosing. During the early winter period, 2008, laboratory tests were made of the liquid nutrient pump system, and it was noted that small amounts of air were being entrained on the suction side of the pump, during conditions when the inlet pressure was low. It was believed that this was the cause of diurnal fluctuations in the flow supplied, characteristic of the 2007 year flow data. Replacement of '0' rings on the inlet side of the pumps was the solution to this problem, and when tested in the field during the summer season, the flow supplied was found to be stable. A decision was made by the IKERT committee at the meeting of 20th to 21st May 2008 (held in Coeur d'Alene, Idaho) to use an injection flow rate of liquid fertilizer (polyammonium phosphate 10-34-0) to achieve a target phosphorus concentration of 3.0 {micro}g/L, after complete mixing in the river. This target concentration was the same as that used in 2006 and 2007. The proposed starting date was as early as possible in June 2008. Plans were made to measure the dosing flow in three ways. Two of the three methods of flow measurement (1 and 2 below) are inter-dependent. These were: (1) Direct measurement of flow rate by diverting dosing flow into a 1000 mL volume standard flask. The flow rate was computed by dividing the flask volume by the time required to fill the flask. This was done a few times only during the summer period. (2) Adjusting the flow rate reading of the Gamma dosing pump using the 'calibration' function to achieve agreement with the flow rate computed by method 1 above. (3) Direct measurement by electrical signal from conductive fluid passing through a magnetic field (Seametrics meter, as used in previous years). Values were recorded every 4 minutes by a data-logger. This instrument has been shown to be reliable, and in agreement with method 1 to within the expected uncertainty (within 2%). Liquid nutrients were delivered to the site in late May, and system testing was done the same day. High concentrations of suspended sediment in the water column, as indicated by shallow Secchi depth readings, were present in the river in the last part of May, into June. A plan was made to delay the start up of nutrient addition to a date later than 1st June, because the aquatic productivity was almost certainly to be compromised by insufficient light availability. Daily monitoring of Secchi depths was done, showing declining turbidity in early June. A decision was made to start the system on 15th June, by which time conditions were good.

Brookhaven program to develop a helium-cooled power transmission system  

SciTech Connect

The particular system under design consists of flexible cables installed in a cryogenic enclosure at room temperature and cooled to the range 6 to 9$sup 0$K by supercritical helium, contraction of the cable is accommodated by proper choice of helix angles of the components of the cable. The superconductor is Nb$sub 3$Sn and at the present time the dielectric insulation is still the subject of intensive development. Two good choices appear to be forms of polyethylene and polycarbonate. Sample cables incorporating various dielectrics have been manufactured commercially in lengths of 1500 ft and tested in laboratory cryostats in shorter sections of about 70 ft. A test facility is under construction to evaluate cables and cryogenic components for this type of service, the first refrigerator uses a 350 H.P. screw compressor and three turbo- expander stages. It is hoped to achieve reliability of a very high order. The first three-phase tests will be conducted at 69 kV, although it appears that 230 to 345 kV is the most likely voltage range for future applications. (auth)

Raft River monitor well potentiometric head responses and water quality as related to the conceptual ground-water flow system  

DOE Green Energy (OSTI)

Ground-water monitoring near the Raft River site was initiated in 1974 by the IDWR. This effort consisted of semiannual chemical sampling of 22 irrigation wells near the Raft River geothermal development area. This program yielded useful baseline chemical data; however, several problems were inherent. For example, access to water pumped from the wells is limited to the irrigation season (April through September). All the wells are not continuously pumped; thus, some wells that are sampled one season cannot be sampled the next. In addition, information on well construction, completion, and production is often unreliable or not available. These data are to be supplemented by establishing a series of monitor wells in the proposed geothermal withdrawal and injection area. These wells were to be located and designed to provide data necessary for evaluating and predicting the impact of geothermal development on the Shallow Aquifer system.

Enhanced Geothermal System Potential for Sites on the Eastern Snake River Plain, Idaho  

SciTech Connect

The Snake River volcanic province overlies a thermal anomaly that extends deep into the mantle and represents one of the highest heat flow provinces in North America (Blackwell and Richards, 2004). This makes the Snake River Plain (SRP) one of the most under-developed and potentially highest producing geothermal districts in the United States. Elevated heat flow is typically highest along the margins of the topographic SRP and lowest along the axis of the plain, where thermal gradients are suppressed by the Snake River aquifer. Beneath this aquifer, however, thermal gradients rise again and may tap even higher heat flows associated with the intrusion of mafic magmas into the mid-crustal sill complex (e.g., Blackwell, 1989).

Digital Mapping and Environmental Characterization of National Wild and Scenic River Systems  

SciTech Connect

Spatially accurate geospatial information is required to support decision-making regarding sustainable future hydropower development. Under a memorandum of understanding among several federal agencies, a pilot study was conducted to map a subset of National Wild and Scenic Rivers (WSRs) at a higher resolution and provide a consistent methodology for mapping WSRs across the United States and across agency jurisdictions. A subset of rivers (segments falling under the jurisdiction of the National Park Service) were mapped at a high resolution using the National Hydrography Dataset (NHD). The spatial extent and representation of river segments mapped at NHD scale were compared with the prevailing geospatial coverage mapped at a coarser scale. Accurately digitized river segments were linked to environmental attribution datasets housed within the Oak Ridge National Laboratory s National Hydropower Asset Assessment Program database to characterize the environmental context of WSR segments. The results suggest that both the spatial scale of hydrography datasets and the adherence to written policy descriptions are critical to accurately mapping WSRs. The environmental characterization provided information to deduce generalized trends in either the uniqueness or the commonness of environmental variables associated with WSRs. Although WSRs occur in a wide range of human-modified landscapes, environmental data layers suggest that they provide habitats important to terrestrial and aquatic organisms and recreation important to humans. Ultimately, the research findings herein suggest that there is a need for accurate, consistent, mapping of the National WSRs across the agencies responsible for administering each river. Geospatial applications examining potential landscape and energy development require accurate sources of information, such as data layers that portray realistic spatial representations.

Effects of the Operation of Hungry Horse Dam on the Kokanee Fishery in the Flathead River System, 1984 Annual Progress Report.  

DOE Green Energy (OSTI)

This study assessed the effects of the operation of Hungry Horse Dam on the kokanee fishery in the Flathead River system. This report covers the 1983-84 field season concerning the effects of Hungry Horse operations on kokanee abundance and reproductive success in the upper Flathead River system. This report also addresses the projected recovery of the main stem kokanee run under the flow regime recommended by the Department of Fish, Wildlife and Parks and implemented by the Bureau of Reclamation and Bonneville Power Administration in 1982. An estimated 58,775 kokanee reached spawning grounds in the Flathead River System in 1983. The 1983 spawning run was composed of 92% age III + fish, as compared to an average of 80% from 1972-1983. A total of 6883 kokanee redds were enumerated in the main stem Flathead River in 1983. A total of 2366 man-days of angling pressure was estimated during the 1983 kokanee lure fishery in the Flathead River system. Estimated numbers of fry emigrating from McDonald Creek, the Whitefish River and Brenneman's Slough were 13,100,000, 66,254 and 37,198, yielding egg to fry survival rates of 76%, 10.4% and 19.2%.

Managing the Yellowstone River System with Place-based Cultural Data  

E-Print Network (OSTI)

This project aims to create new research tools within the human dimensions (HD) of the natural resources field to improve environmental policy decision making. It addresses problems that arise from the recent trend towards decentralized natural resource management (NRM) and planning (e.g., community-based planning, watershed-based and collaborative management, others). By examining one decentralized riparian management planning effort along the Yellowstone River (Montana), this study finds that decentralization forces new needs such as localized information requirements and a better understanding of the rationales behind local interests. To meet these new scale demands and to ensure that policy best fits the social and biophysical settings, this project argues that local cultural knowledge can serve as an organizing framework for delivering the kinds of understanding needed for decentralized planning. This was tested by interviewing 313 riverfront landowners, recreationalists, and civic managers to understand how residents conceptualize the rivers natural processes, its management, and their desires for the future of the river. Analysis of the transcribed in-depth interview textsthe Yellowstone River Cultural Inventory (YRCI)found that: (1) altering decision venues places more significance upon interpersonal working relationships between managers and citizens; (2) while local expertise can provide higher quality information to managers, local decision making cultures still retain power dynamics that can inhibit or advance conservation policies; (3) how natural resource places are symbolically communicated has a material impact upon resource uses; (4) how residents conceptualize the ownership of land is complicated along a dynamic river; and (5) this dynamism impacts planning efforts. In sum, this project argues that for social research to provide the data and analysis appropriate, a modification in scale and a commensurate shift in the lenses used for social inquiry is necessary. An in-depth understanding of local cultureslike the YRCIenables agencies to best manage in decentralized scales of planning by calling attention to site-specific nuances such as power dynamics and place representation which are often missed in traditional large-scale HD methods and lenses. This research also functions as a preemptive way to engage the public in environmental planning helping decision makers best fit policy to particular socio-cultural and ecological settings.

Automated manual transmission clutch controller  

DOE Patents (OSTI)

A powertrain system for a hybrid vehicle. The hybrid vehicle includes a heat engine, such as a diesel engine, and an electric machine, which operates as both an electric motor and an alternator, to power the vehicle. The hybrid vehicle also includes a manual-style transmission configured to operate as an automatic transmission from the perspective of the driver. The engine and the electric machine drive an input shaft which in turn drives an output shaft of the transmission. In addition to driving the transmission, the electric machine regulates the speed of the input shaft in order to synchronize the input shaft during either an upshift or downshift of the transmission by either decreasing or increasing the speed of the input shaft. When decreasing the speed of the input shaft, the electric motor functions as an alternator to produce electrical energy which may be stored by a storage device. Operation of the transmission is controlled by a transmission controller which receives input signals and generates output signals to control shift and clutch motors to effect smooth launch, upshift shifts, and downshifts of the transmission, so that the transmission functions substantially as an automatic transmission from the perspective of the driver, while internally substantially functioning as a manual transmission.

HVDC power transmission technology assessment  

SciTech Connect

The purpose of this study was to develop an assessment of the national utility system`s needs for electric transmission during the period 1995-2020 that could be met by future reduced-cost HVDC systems. The assessment was to include an economic evaluation of HVDC as a means for meeting those needs as well as a comparison with competing technologies such as ac transmission with and without Flexible AC Transmission System (FACTS) controllers. The role of force commutated dc converters was to be assumed where appropriate. The assessment begins by identifying the general needs for transmission in the U.S. in the context of a future deregulated power industry. The possible roles for direct current transmission are then postulated in terms of representative scenarios. A few of the scenarios are illustrated with the help of actual U.S. system examples. non-traditional applications as well as traditional applications such as long lines and asynchronous interconnections are discussed. The classical ``break-even distance`` concept for comparing HVDC and ac lines is used to assess the selected scenarios. The impact of reduced-cost converters is reflected in terms of the break-even distance. This report presents a comprehensive review of the functional benefits of HVDC transmission and updated cost data for both ac and dc system components. It also provides some provocative thoughts on how direct current transmission might be applied to better utilize and expand our nation`s increasingly stressed transmission assets.

Information retrieval system: impacts of water-level changes on uses of federal storage reservoirs of the Columbia River.  

DOE Green Energy (OSTI)

A project undertaken to provide the Bonneville Power Administration (BPA) with information needed to conduct environmental assessments and meet requirements of the National Environmental Policy Act (NEPA) and the Pacific Northwest Electric Power Planning and Conservation Act (Regional Act) is described. Access to information on environmental effects would help BPA fulfill its responsibilities to coordinate power generation on the Columbia River system, protect uses of the river system (e.g., irrigation, recreation, navigation), and enhance fish and wildlife production. Staff members at BPA identified the need to compile and index information resources that would help answer environmental impact questions. A computer retrieval system that would provide ready access to the information was envisioned. This project was supported by BPA to provide an initial step toward a compilation of environmental impact information. Scientists at Pacific Northwest Laboratory (PNL) identified, gathered, and evaluated information related to environmental effects of water level on uses of five study reservoirs and developed and implemented and environmental data retrieval system, which provides for automated storage and retrieval of annotated citations to published and unpublished information. The data retrieval system is operating on BPA's computer facility and includes the reservoir water-level environmental data. This project was divided into several tasks, some of which were conducted simultaneously to meet project deadlines. The tasks were to identify uses of the five study reservoirs, compile and evaluate reservoir information, develop a data entry and retrieval system, identify and analyze research needs, and document the data retrieval system and train users. Additional details of the project are described in several appendixes.

Data Management Plan and Functional System Design for the Information Management System of the Clinch River Remedial Investigation and Waste Area Grouping 6  

Science Conference Proceedings (OSTI)

The Data Management Plan and Functional System Design supports the Clinch River Remedial Investigation (CRRI) and Waste Area Grouping (WAG) 6 Environmental Monitoring Program. The objective of the Data Management Plan and Functional System Design is to provide organization, integrity, security, traceability, and consistency of the data generated during the CRRI and WAG 6 projects. Proper organization will ensure that the data are consistent with the procedures and requirements of the projects. The Information Management Groups (IMGs) for these two programs face similar challenges and share many common objectives. By teaming together, the IMGs have expedited the development and implementation of a common information management strategy that benefits each program.
