Substation voltage upgrading  

SciTech Connect

Substation voltage uprating, i.e., conversion of a substation from a lower rated voltage to a higher rated voltage without a complete substation rebuild, can lead to excellent economic benefits. Utilization of the old substation layout and/or the existing equipment, to some extent, is the practical objective of such an uprating. The objective of this project was to assess the opportunities for substation uprating in the industry, to establish feasibility for such uprating and to study methods for accomplishing it. The final aim of the project was to provide guidance to utilities interested in uprating. 56 refs., 41 figs., 18 tabs.

Substation voltage upgrading  

SciTech Connect

This report addresses specific issues to support sound yet not unduly conservative uprating practices for substations. The main parts of the report cover the insulation withstand and overvoltage protection aspects, environmental measurements, reliability criteria, and industry experience. First the insulation design concerns are addressed. Substation stress by a backflashover of the line insulation due to lightning in the vicinity of the substation is recognized as a critical stress. A representative part of a 550 kV BIL substation was erected at the EPRI High Voltage Transmission Research Center, where also a special test circuit was assembled to produce a fast front, slow tail (0.2/200 {mu}s) wave. The substation as well as some special configurations were tested for line-to-ground and line-to-line withstand. Computer studies were performed to complement the test results. A number of important conclusions was reached. The most prominent result in that the high frequency oscillations, as caused by reflections within the substation, do not effect the Critical Flashover Voltage (CFO). The present practice, based on the highest peak is therefore very conservative. The slow tail of the wave appears to dictate the CFO. An arrester model for computer studies to represent very fast as well as slow phenomena was derived. It is based on full scale arrester test data, made available in this project. The computer program to calculate arrester model parameters is also a part of the report. The electric environmental measurements are reported for the tested substation at the HVTRC and for the uprated substation of Public Service Company of Colorado, both before and after the uprating. The performance is satisfactory when corona free hardware is used. Insulation design criteria are analyzed based on substation reliability, the system viewpoint and consequences of the failure. Utility experience with uprated substations is reviewed.

Bidirectional buck boost converter  

DOE Patents (OSTI)

A bidirectional buck boost converter and method of operating the same allows regulation of power flow between first and second voltage sources in which the voltage level at each source is subject to change and power flow is independent of relative voltage levels. In one embodiment, the converter is designed for hard switching while another embodiment implements soft switching of the switching devices. In both embodiments, first and second switching devices are serially coupled between a relatively positive terminal and a relatively negative terminal of a first voltage source with third and fourth switching devices serially coupled between a relatively positive terminal and a relatively negative terminal of a second voltage source. A free-wheeling diode is coupled, respectively, in parallel opposition with respective ones of the switching devices. An inductor is coupled between a junction of the first and second switching devices and a junction of the third and fourth switching devices. Gating pulses supplied by a gating circuit selectively enable operation of the switching devices for transferring power between the voltage sources. In the second embodiment, each switching device is shunted by a capacitor and the switching devices are operated when voltage across the device is substantially zero. 20 figs.

Substation grounding programs  

SciTech Connect

This document is a users manual and applications guide for the software package SGA. This package comprises four computer programs, namely SOMIP, SMECC, SGSYS, and TGRND. The first three programs are analysis models which are to be used in the design process of substation grounding systems. The fourth program, TGRND, is an analysis program for determining the transient response of a grounding system. This report, Volume 5, is an applications guide of the three computer programs. SOMIP, SMECC, and SGSYS, for the purpose of designing a safe substation grounding system. The applications guide utilizes four example substation grounding systems for the purpose of illustrating the application of the programs, SOMIP, SMECC, and SGSYS. The examples are based on data provided by four contributing utilities, namely, Houston Lighting and Power Company, Southern Company Services, Puget Sound Power and Light Company, and Arizona Public Service Company. For the purpose of illustrating specific capabilities of the computer programs, the data have been modified. As a result, the final designs of the four systems do not necessarily represent actual grounding system designs by these utilities. The example system 1 is a 138 kV/35 kV distribution substation. The example system 2 is a medium size 230 kV/115 kV transmission substation. The third example system is a generation substation while the last is a large 525 kV/345 kV/230 kV transmission substation. The four examples cover most of the practical problems that a user may encounter in the design of substation grounding systems.

Cutting costs through substation ownership  

SciTech Connect

The term applied to service through a customer-owned main substation is primary service, and such customers are billed at primary metering rates. These terms denote that the customer accepts service (and billing metering is located) on the primary, rather than secondary, side of the main transformer. Some electric utilities are prepared to offer extremely attractive billing reductions to those customers willing to invest in their own main substations instead of renting a substation purchased with utility company capital. Depending on the utility and the particular circumstances, some plants can recover their investment in primary substation equipment in as little as 1 or 2 years.

Substation Reliability Centered Maintenance  

SciTech Connect

Substation Reliability Centered Maintenance (RCM) is a technique that is used to develop maintenance plans and criteria so the operational capability of substation equipment is achieved, restored, or maintained. The objective of the RCM process is to focus attention on system equipment in a manner that leads to the formulation of an optimal maintenance plan. The RCM concept originated in the airline industry in the 1970s and has been used since 1985 to establish maintenance requirements for nuclear power plants. The RCM process is initially applied during the design and development phase of equipment or systems on the premise that reliability is a design characteristic. It is then reapplied, as necessary, during the operational phase to sustain a more optimal maintenance program based on actual field experiences. The purpose of the RCM process is to develop a maintenance program that provides desired or specified levels of operational safety and reliability at the lowest possible overall cost. The objectives are to predict or detect and correct incipient failures before they occur or before they develop into major defects, reduce the probability of failure, detect hidden problems, and improve the cost-effectiveness of the maintenance program. RCM accomplishes two basic purposes: (1) It identifies in real-time incipient equipment problems, averting potentially expensive catastrophic failures by communicating potential problems to appropriate system operators and maintenance personnel. (2) It provides decision support by recommending, identifying, and scheduling preventive maintenance. Recommendations are based on maintenance criteria, maintenance history, experience with similar equipment, real-time field data, and resource constraints. Hardware and software are used to accomplish these two purposes. The RCM system includes instrumentation that monitors critical substation equipment as well as computer software that helps analyze equipment data.

Fault diagnosis using substation computer  

SciTech Connect

A number of substation integrated control and protection systems (ICPS) are being developed around the world, where the protective relaying, control, and monitoring functions of a substation are implemented using microprocessors. In this design, conventional relays and control devices are replaced by clusters of microprocessors, interconnected by multiplexed digital communication channels using fibre optic, twisted wire pairs or coaxial cables. The ICPS incorporates enhanced functions of value to the utility and leads to further advancement of the automation of transmission substations. This paper presents an automated method of fault diagnosis which can be incorporated in the station computer of an integrated control and protection system. The effectiveness of this method is demonstrated using a transmission-level substation as an example.

Electric power substation capital costs  

SciTech Connect

The displacement or deferral of substation equipment is a key benefit associated with several technologies that are being developed with the support of the US Department of Energy`s Office of Utility Technologies. This could occur, for example, as a result of installing a distributed generating resource within an electricity distribution system. The objective of this study was to develop a model for preparing preliminary estimates of substation capital costs based on rudimentary conceptual design information. The model is intended to be used by energy systems analysts who need ``ballpark`` substation cost estimates to help establish the value of advanced utility technologies that result in the deferral or displacement of substation equipment. This cost-estimating model requires only minimal inputs. More detailed cost-estimating approaches are recommended when more detailed design information is available. The model was developed by collecting and evaluating approximately 20 sets of substation design and cost data from about 10 US sources, including federal power marketing agencies and private and public electric utilities. The model is principally based on data provided by one of these sources. Estimates prepared with the model were compared with estimated and actual costs for the data sets received from the other utilities. In general, good agreement (for conceptual level estimating) was found between estimates prepared with the cost-estimating model and those prepared by the individual utilities. Thus, the model was judged to be adequate for making preliminary estimates of typical substation costs for US utilities.

Scoping study: Substation design workstation  

SciTech Connect

This project conducted a survey, consisting of a written questionaire, a workshop, and site visits to determine what facets of substation engineering would benefit from incorporation into a workstation environment. Based on the needs expressed by the respondents, a program for the staged development of a Substation Workstation is recommended. Six analytical function modules for assisting in substation engineering were identified for potential inclusion in the workstation: Initial Planning Activities; Physical Plant Design; Analytical Functions; Civil/Structural Design; Environmental Design; and Project Management. The initial release of the Substation Workstation is recommended to include the workstation environment (including MENTOR -- a concept for on-line help, tutorials, notepad, a minor spreadsheet, and interfaces to other regular desktop functions) and portions of the first three functional modules listed above. Recommendations for progress beyond this first release of the workstation included the development of additional capabilities within the initial functional modules, as well as the development of the remaining modules. An overlap exists between the analytical requirements for this workstation and those already included in the EPRI TLWorkstation and the ICWorkstation. In some cases, elements of these other workstations are also suggested for incorporation into the Substation Workstation (such as the foundation analyses from the TLWorkstation), and in others, an assimilation of the other workstation into the Substation Workstation is recommended (as with the ICWorkstation). Estimated resources for implementing the recommended program, including both costs and development time, are also provided.

Ashland Area Support Substation Project  

Science Conference Proceedings (OSTI)

The Bonneville Power Administration (BPA) provides wholesale electric service to the City of Ashland (the City) by transferring power over Pacific Power Light Company's (PP L) 115-kilovolt (kV) transmission lines and through PP L's Ashland and Oak Knoll Substations. The City distributes power over a 12.5-kV system which is heavily loaded during winter peak periods and which has reached the limit of its ability to serve peak loads in a reliable manner. Peak loads under normal winter conditions have exceeded the ratings of the transformers at both the Ashland and Oak Knoll Substations. In 1989, the City modified its distribution system at the request of PP L to allow transfer of three megawatts (MW's) of electric power from the overloaded Ashland Substation to the Oak Knoll Substation. In cooperation with PP L, BPA installed a temporary 6-8 megavolt-amp (MVA) 115-12.5-kV transformer for this purpose. This additional transformer, however, is only a temporary remedy. BPA needs to provide additional, reliable long-term service to the Ashland area through additional transformation in order to keep similar power failures from occurring during upcoming winters in the Ashland area. The temporary installation of another 20-MVA mobile transformer at the Ashland Substation and additional load curtailment are currently being studied to provide for sustained electrical service by the peak winter period 1992. Two overall electrical plans-of-service are described and evaluated in this report. One of them is proposed for action. Within that proposed plan-of-service are location options for the substation. Note that descriptions of actions that may be taken by the City of Ashland are based on information provided by them.

East Grangeville Substation : Environmental Assessment.  

SciTech Connect

BPA proposes to build a 6/8 MVA, 115/13.8-kV substation about 0.7 mile (1.2 km) east of Grangeville, Idaho. BPA's substation yard would comprise an area of 70 by 72 feet (21 by 22 m) containing a 115/13.8-kV transformer. Energization for the substation is scheduled for September 1983. In connected actions the Co-op would build a 13.8-kV switching station and a 13.8/34.5-kV step-up station. The Co-op would require an area of 100 by 55 feet (31 by 17 m) in addition to the BPA yard. The total area needed for the combined BPA/Co-op substation would be approximately 170 by 127 feet (52 by 40 m) or one-half of an acre (0.20 ha). The Co-op would also build two 13.8-kV feeders and one 34.5-kV feeder underground south of the substation to overhead distribution lines along State Highway 13 with space for one future feeder. Another 13.8-kV feeder would exit the substation underground and loop around to the north to reconnect to the existing 13.8-kV overhead line. TWWP would build a tapline from their Grangeville-Kamiah-Nez Perce (Grangeville-Nez Perce No. 2) 115-kV transmission line to the substation. This line would be approximately 0.75 mile (1.2 km) long and would consist of single wood pole structures built on the route of an existing Co-op distribution line. The new and existing lines would use the same poles. A temporary access road would be built for 0.25 mile (0.4 km). The remaining 0.5 mile (0.8 km) section would be adjacent to a county road and would not require an access road. Two sites were identified as meeting the technical requirements. Site 2 is recommended.

MOV surge arresters: improved substation equipment protection  

Science Conference Proceedings (OSTI)

The introduction of metal-oxide-varistor (MOV) surge arresters has added a new dimension to substation equipment protection. Through the optimal use of these arresters, it is possible to lower surge arrester ratings and thereby improve protective margins, resulting in a possible reduction of the insulation levels (BIL) of substation equipment. This reduction in BIL can lead to a significant reduction in the cost of substation equipment. General methods are delineated for selecting MOV surge arresters for substation protection and the resulting effect on substation equipment insulation levels.

Wolf Point Substation, Roosevelt County, Montana  

Science Conference Proceedings (OSTI)

The Western Area Power Administration (Western), an agency of the United States Department of Energy, is proposing to construct the 115-kV Wolf Point Substation near Wolf Point in Roosevelt County, Montana (Figure 1). As part of the construction project, Western's existing Wolf Point Substation would be taken out of service. The existing 115-kV Wolf Point Substation is located approximately 3 miles west of Wolf Point, Montana (Figure 2). The substation was constructed in 1949. The existing Wolf Point Substation serves as a Switching Station'' for the 115-kV transmission in the region. The need for substation improvements is based on operational and reliability issues. For this environmental assessment (EA), the environmental review of the proposed project took into account the removal of the old Wolf Point Substation, rerouting of the five Western lines and four lines from the Cooperatives and Montana-Dakota Utilities Company, and the new road into the proposed substation. Reference to the new proposed Wolf Point Substation in the EA includes these facilities as well as the old substation site. The environmental review looked at the impacts to all resource areas in the Wolf Point area. 7 refs., 6 figs.

Probabilistic economic evaluation of substation seismic upgrade  

SciTech Connect

This paper presents a methodology for deciding whether or not to implement seismic design modifications at Southern California Edison's (SCE) Substation facilities. The method considers the potential for substation capability loss resulting from earthquake damage, cost of seismic modification made today, the cost of damage restoration after that modification is made, the cost of doing nothing now, and the site specific earthquake probability. Based on these findings, recommendations for seismic modifications of substation facilities could be made.

Substation evaluation using Diagnostic Logic System (DIALOG)  

Science Conference Proceedings (OSTI)

This project investigated the feasibility of applying a Diagnostic Logic System (DIAGLOG) to evaluate substation operation. The purpose was to see if a determination can be made as to whether the equipment in a substation operated correctly or not when an operating event occurred. The work was directed toward modifying an already proven diagnostic system to create a simplified procedure for describing the operation of substation equipment. Special operating tables or modules of logic were identified for describing relay and breaker operations. The resulting model composed of all the modules connected together is used to evaluate the actual observations available at the substation, and to compare them with what the substation should have produced. The report covers the diagnostic approach used, information on how to construct the modules and examples of diagnosis. Also covered are discussions on the special features of substations that offer a challenge to performing diagnostics. Included in the report are the results of modeling a typical substation and several notes are provided along with an initial library of typical modules which were developed in modeling one of the substations belonging to the Pacific Gas and Electric Company. This substation served as a feasibility demonstrator. 15 figs.

Investigation of electric fields of EHV substations  

SciTech Connect

60-Hz and 24-kHz capacitive and monopole probes and testing techniques were developed for full-scale and model ground level electric field strength measurements for EHV substations. A model of an existing 345-kV substation was designed and built. The model was energized using a three phase 24-kHz regulated source. Comparison of corresponding test points shows that the agreement between substation and model measurements is good. Large amounts of model test data can be taken in a short time. Energized scale models can be used in a substation design tool so that the electric field may be mapped and, if necessary, modified. A successful and useful predictive tool has been developed that can handle the three-dimensional complex substation electric fields. Further development will result in a widely available and flexible analog design tool.

Single Inductor Dual Output Buck Converter  

E-Print Network (OSTI)

The portable electronics market is rapidly migrating towards more compact devices with multiple functionalities. Form factor, performance, cost and efficiency of these devices constitute the factors of merit of devices like cell phones, MP3 players and PDA's. With advancement in technology and more intelligent processors being used, there is a need for multiple high integrity voltage supplies for empowering the systems in portable electronic devices. Switched mode power supplies (SMPS's) are used to regulate the battery voltage. In an SMPS, maximum area is taken by the passive components such as the inductor and the capacitor. This work demonstrates a single inductor used in a buck converter with two output voltages from an input battery with voltage of value 3V. The main focus areas are low cross regulation between the outputs and supply of completely independent load current levels while maintaining desired values (1.2V,1.5V) within well controlled ripple levels. Dynamic hysteresis control is used for the single inductor dual output buck converter in this work. Results of schematic and post layout simulations performed in CADENCE prove the merits of this control method, such as nil cross regulation and excellent transient response.

A Dual Supply Buck Converter with Improved Light Load Efficiency  

E-Print Network (OSTI)

Power consumption is the primary concern in battery-operated portable applications. Buck converters have gained popularity in powering portable devices due to their compact size, good current delivery capability and high efficiency. However, portable devices are operating under light load condition for the most of the time. Conventional buck converters suffer from low light-load efficiency which severely limits battery lifetime. In this project, a novel technique for buck converter is proposed to reduce the switching loss by reducing the effective input supply voltage at light load. This is achieved by switching between two different input voltages (3.3V and 1.65V) depending on the output current value. Experimental results show that this technique improves the efficiency at light loads by 18.07%. The buck voltage possesses an output voltage of 0.9V and provides a maximum output current of 400mA. The buck converter operates at a switching frequency of 1MHz. The prototype was fabricated using 0.18µm CMOS technology, and occupies a total active area of 0.6039mm^2.

Ashland Area Support Substation Project : Environmental Assessment.  

SciTech Connect

The Bonneville Power Administration (BPA) provides wholesale electric service to the City of Ashland (the City) by transferring power over Pacific Power & Light Company`s (PP&L) 115-kilovolt (kV) transmission lines and through PP&L`s Ashland and Oak Knoll Substations. The City distributes power over a 12.5-kV system which is heavily loaded during winter peak periods and which has reached the limit of its ability to serve peak loads in a reliable manner. Peak loads under normal winter conditions have exceeded the ratings of the transformers at both the Ashland and Oak Knoll Substations. In 1989, the City modified its distribution system at the request of PP&L to allow transfer of three megawatts (MW`s) of electric power from the overloaded Ashland Substation to the Oak Knoll Substation. In cooperation with PP&L, BPA installed a temporary 6-8 megavolt-amp (MVA) 115-12.5-kV transformer for this purpose. This additional transformer, however, is only a temporary remedy. BPA needs to provide additional, reliable long-term service to the Ashland area through additional transformation in order to keep similar power failures from occurring during upcoming winters in the Ashland area. The temporary installation of another 20-MVA mobile transformer at the Ashland Substation and additional load curtailment are currently being studied to provide for sustained electrical service by the peak winter period 1992. Two overall electrical plans-of-service are described and evaluated in this report. One of them is proposed for action. Within that proposed plan-of-service are location options for the substation. Note that descriptions of actions that may be taken by the City of Ashland are based on information provided by them.

Planning substation capacity under the single-contingency scenario  

Science Conference Proceedings (OSTI)

Florida Power and Light (FPL) adopts the single contingency emergency policy for its planning of substation capacity. This paper provides an approach to determine the maximum load which a substation can take on under such a policy. The approach consists of two LP models which determine: (1) the maximum substation load capacity, and (2) the reallocation of load when a substation`s demand cannot be met. Both models are formulated under the single-contingency scenario, an issue which had received little attention in the literature. Not only does the explicit treatment of the scenario provide an exact measure of a substation`s load limit, it also raises several important issues which previous works omit. These two models have been applied to the substation network of the Fort Myers District of the State of Florida.

Demonstration Assessment of LED Roadway Lighting: NE Cully Boulevard Portland, OR  

Science Conference Proceedings (OSTI)

A new roadway lighting demonstration project was initiated in late 2010, which was planned in conjunction with other upgrades to NE Cully Boulevard, a residential collector road in the northeast area of Portland, OR. With the NE Cully Boulevard project, the Portland Bureau of Transportation hoped to demonstrate different light source technologies and different luminaires side-by-side. This report documents the initial performance of six different newly installed luminaires, including three LED products, one induction product, one ceramic metal halide product, and one high-pressure sodium (HPS) product that represented the baseline solution. It includes reported, calculated, and measured performance; evaluates the economic feasibility of each of the alternative luminaires; and documents user feedback collected from a group of local Illuminating Engineering Society (IES) members that toured the site. This report does not contain any long-term performance evaluations or laboratory measurements of luminaire performance. Although not all of the installed products performed equally, the alternative luminaires generally offered higher efficacy, more appropriate luminous intensity distributions, and favorable color quality when compared to the baseline HPS luminaire. However, some products did not provide sufficient illumination to all areas—vehicular drive lanes, bicycle lanes, and sidewalks—or would likely fail to meet design criteria over the life of the installation due to expected depreciation in lumen output. While the overall performance of the alternative luminaires was generally better than the baseline HPS luminaire, cost remains a significant barrier to widespread adoption. Based on the cost of the small quantity of luminaires purchased for this demonstration, the shortest calculated payback period for one of the alternative luminaire types was 17.3 years. The luminaire prices were notably higher than typical prices for currently available luminaires purchased in larger quantities. At prices that are more typical, the payback would be less than 10 years. In addition to the demonstration luminaires, a networked control system was installed for additional evaluation and demonstration purposes. The capability of control system to measure luminaire input power was explored in this study. A more exhaustive demonstration and evaluation of the control system will be the subject of future GATEWAY report(s).

Modeling and Simulating Blast Effects on Electric Substations  

Science Conference Proceedings (OSTI)

A software simulation tool was developed at the Idaho National Laboratory to estimate the fragility of electric substation components subject to an explosive blast. Damage caused by explosively driven fragments on a generic electric substation was estimated by using a ray-tracing technique to track and tabulate fragment impacts and penetrations of substation components. This technique is based on methods used for assessing vulnerability of military aircraft and ground vehicles to explosive blasts. An open-source rendering and ray-trace engine was used for geometric modeling and interactions between fragments and substation components. Semi-empirical material interactions models were used to calculate blast parameters and simulate high-velocity material interactions between explosively driven fragments and substation components. Finally, a Monte Carlo simulation was added to model the random nature of fragment generation allowing a skilled analyst to predict failure probabilities of substation components.

Data collecting and processing for substation integration enhancement  

E-Print Network (OSTI)

The issue of substation integration is recognized as a very important one ever since the process of technological development brought a multitude of new computer-based devices and functions into substation operation. During the relatively short time period after the first microprocessors were invented, a myriad of computer-based devices found their application in power engineering. Those devices had a variety of input and output data formats, which hampered exchange of data among different devices. Recent initiatives for standardization of substation data formats and communication protocols have progressed to facilitate production of devices with standardized data formats and data exchange capabilities. Central substation computers now have an opportunity to collect and process data from such computer-based devices. An advanced data collecting and processing solution is developed and implemented as Integrated Substation Software in an effort to enhance substation integration. This report describes a solution that comprises data generation using a substation model, data collecting from modeled apparatus and instruments and finally application of data processing and consistency checking algorithms for creating outputs. The process of data collecting and processing is automated and repeated in equidistant time intervals. Results of processing and related reports are concisely displayed on the user interface screen and exported through data files. The Substation Integration Software was tested through the set of scenarios where each scenario is used to test one of the processing and consistency checking algorithms. The results show that measurements are improved and applicable for usage by other substation and system-wide applications.

Environmental Assessment of Proposed Filbert Substation and Tap Project.  

SciTech Connect

The proposal is a cooperative (jointly funded and owned) action between Bonneville Power Administration (BPS) and FGLandP involving construction of the 115/12.5-kV Filbert Substation. BPA would also build a 0.8-mile overhead 115-kV tapline from BPA's Forest Grove-McMinnville 115-kV line to the proposed substation. The Forest Grove-McMinnville transmission line has available capacity to support the proposed substation. The FGLandP would build four underground distribution circuits to connect the substation to its existing distribution system. It is normally BPA's practice to consider several substation location alternatives as a part of its facility siting process. The proposed substation site was recommended after a preliminary field evaluation by BPA determined that building on the proposed site was preferable because available sites south of the Tualatin Valley Highway and Southern Pacific Railroad were either on presently cultivated farmland, were in a floodplain, or were inaccessible without extensive access road construction. The proposed substation site is owned by FGLandP, is designated for use as a utility substation in the Forest Grove Comprehensive Plan, and was purchased by FGLandP in anticipation of a need for its use as a substation site because of its central location in relation to existing and forecasted loads. The site is accessible from Filbert Street (city road), and is gently sloping. This report describes potential environmental impacts of the proposed actions.

Screening level characterization of electrical Substation 411  

SciTech Connect

Substation 411 transformer dielectric fluids were sampled for uranium and PCBs. The exterior surfaces of the metal transformers were measured for radioactivity. Results of the sampling revealed that some transformer fluid contained PCBs, but no uranium in excess of naturally occurring amounts was detected. In addition, the exterior surface of the transformers were uncontaminated. Subject to measurement of the base of the transformers (which were inaccessible during the surface scans for radioactivity), the transformers and dielectric fluids may be removed from the site for disposal. Two appendices are included: (a) a sampling plan, and (b) soil lab reports.

Grizzly Substation Fiber Optics : Environmental Assessment.  

SciTech Connect

This notice announces BPA`s decision to construct, operate, and maintain the Grizzly Substation Fiber Optic Project (Project). This Project is part of a continuing effort by BPA to complete a regionwide upgrade of its existing telecommunications system. The US Forest Service and BPA jointly prepared the Grizzly Substation Fiber Optic Project Environmental Assessment (EA) (DOE/EA-1241) evaluating the potential environmental impacts of the Proposed Action, the Underground Installation Alternative, and the No Action Alternative. Based on the analysis in the EA, the US Forest Service and BPA have determined that the Proposed Action is not a major Federal action significantly affecting the quality of the human environment, within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an Environmental Impact Statement (EIS) is not required and BPA is issuing this FONSI. The US Forest Service has separately issued a FONSI and Decision Notice authorizing BPA to construct, operate, and maintain the Project within the Crooked River National Grassland (Grassland).

APS team works smarter, cuts substation construction costs by 36%  

SciTech Connect

An aggressive, cost-cutting, team of T D employees at Arizona Public Service Co (APS) is building a new distribution substation in Phoenix for less than half the original cost that APS planners had calculated for the project's land, labor and materials. Scheduled for service in June of this year, APS analysts had originally projected land, labor and materials costs for the 20-MVA Bell substation at nearly $1.7-million-not including major equipment such as transformers, circuit breakers, and switches. However, after studying the project, an empowered APS crew was able to slash 36% off the original estimate-more than $610,000. What's more, APS spokesmen say that its new approach to substation construction and design has given its engineers and construction crews a laundry list of additional ideas to try out on future substation ventures. 4 figs., 1 tab.

National SCADA Test Bed Substation Automation Evaluation Report  

Science Conference Proceedings (OSTI)

Increased awareness of the potential for cyber attack has recently resulted in improved cyber security practices associated with the electrical power grid. However, the level of practical understanding and deployment of cyber security practices has not been evenly applied across all business sectors. Much of the focus has been centered on information technology business centers and control rooms. This report explores the current level of substation automation, communication, and cyber security protection deployed in electrical substations throughout existing utilities in the United States. This report documents the evaluation of substation automation implementation and associated vulnerabilities. This evaluation used research conducted by Newton-Evans Research Company for some of its observations and results. The Newton Evans Report aided in the determination of what is the state of substation automation in North American electric utilities. Idaho National Laboratory cyber security experts aided in the determination of what cyber vulnerabilities may pose a threat to electrical substations. This report includes cyber vulnerabilities as well as recommended mitigations. It also describes specific cyber issues found in typical substation automation configurations within the electric utility industry. The evaluation report was performed over a 5-month period starting in October 2008

Measurement and characterization of substation electromagnetic transients. Final report  

SciTech Connect

Little quantitative data exists on radiated electromagnetic interference in substations arising from substation transients. The electromagnetic transient noise produced by normal substation activity such as opening switches and breakers can be significant. Additionally, abnormal events such as faults cause similar electromagnetic noise. The lack of data is in part because suitable measurement equipment techniques have not been generally available to utilities. A new approach to the measurement and characterization of electromagnetic interference caused by substation transients has been developed. A data acquisition system for measurements has been designed and constructed for field use with a bandwidth capability exceeding 100 MHz. Measurements have been taken from staged operations in substations and the resulting data analyzed using specialized computer programs developed for this project. The measurement techniques are presented and the analysis procedures explained in detail. The transients caused by equipment operations in several substations have been studied resulting in an understanding of the expected or typical amplitudes and frequencies of the resulting noise. Suggestions as to equipment tests and withstand levels have been made. An appendix includes raw and analyzed data for research use.

Cyber Security in Smart Grid Substations  

E-Print Network (OSTI)

Abstract. This report describes the state of smart grid security in Europe, specifically the Netherlands, and the cyber security of substations in particular. The focus of this study is the perception of risks and threats in smart grid cyber security and the international standards implemented in smart grids. The created overview is based on semi-structured interviews with 13 experts originating from eight different European countries. These participants are employed at electricity producers, grid operators, technology consultants and technology providers in the utilities sector. Their expertise ranges from information security to electricity grids, specifically smart grid security. Some of them are members of smart grid security related standard committees. The key results of the state of practice are the following: 1. The interconnectivity of the smart grid with multiple stakeholders and European colleagues is indicated as the biggest threat to the security of the smart grid. 2. Another often mentioned threat is awareness. The experts generally indicate that awareness within top management is high. However, personnel on lower levels are reluctant to incorporate security in their processes. 3. All organizations are in a certain stage of implementing standards, the ISO27000 series

Feasibility of thyristor controlled series capacitor for distribution substation enhancements  

Science Conference Proceedings (OSTI)

While Thyristor Controlled Series Capacitors (TCSCs) are already being used for control of transmission system power flows, the dynamic adjustment of transmission infeed impedances presents other system enhancement opportunities. In the case of the Con Edison system, distribution substation upgrades are severely constrained by limits to existing circuit breaker interrupting capabilities. Because additional transmission line infeeds cannot be provided without increasing fault current levels, a TCSC was investigated for use as a fault current limiter. In order to demonstrate proper operation in the current limiting mode, Electromagnetic Transients Program (EMTP) simulations were conducted. Three TCSC configurations are presented to illustrate that additional power can be provided during normal operation without increasing fault currents at the substation: (1) series compensation of existing 138 kV infeeds (to allow higher substation MVA uprates), (2) series compensation of new 138 kV infeeds (without fault current increases), and (3) a 13.8 kV TCSC compensated link between two substations (to allow regulated power transfer between substation buses).

Transient performance of substation structures and associated grounding systems  

Science Conference Proceedings (OSTI)

When lightning strikes an electric substation, large currents generated by the stroke flow in the above ground structures and grounding system and dissipate in the soil. The electromagnetic fields generated by such high currents may cause damage to equipment and may be dangerous to personnel working nearby. In this paper, the frequency and time domain performance of a substation subjected to a lightning strike is described and discussed. The computed scalar potentials, electric fields, and magnetic fields are presented graphically as a function of spatial coordinates, as a function of time and as a function of both. Two cases are considered. The first case examines the substation grounding system only, while the second case includes an above-ground structure as well. It is believed that the results of the second case have not been published before. A double exponential lightning surge current is injected at one corner of the substation. The response of the grounding system to the frequency domain electromagnetic spectrum of this signal is computed by a frequency domain electromagnetic field analysis software package. The temporal and spatial distributions of the electromagnetic fields inside and near the substation are obtained by an inverse Fourier transformation of all these responses. The presence of a soil with an arbitrary resistivity and permittivity is accurately taken into account. The analysis sheds some new light on the understanding of the effects which take place at the higher frequencies.

Integrated substation looks like one RTU to dispatchers  

SciTech Connect

Traditionally, supervisory control and data acquisition systems (Scada) use a master/slave arrangement. The master Scada computer polls individual circuit devices for information, or the devices may report (by exception) to the computer. The substation engineering department of Portland General Electric Co (PCE) is now pioneering a new arrangement in which all devices in a substation communicate with each other and a local computer over a data bus. A single communications line connects the Scada master to the same bus for control and/or monitoring. The new approach is known as a substation integration system (SIS). Thus, for a lower initial cost, substation integration: eliminates the need for redundant equipment - such as panel meters, annunciators, transducers, sequence-of-event recorders, auxiliary tripping relays. Scada RTU, control, and transfer switches; reduces control house size by 25% by reducing wiring and using panel space more efficiently; provides a standardized user interface for easy data access, both locally and remotely; is flexible and expandable because of its modularity and use of non-proprietary hardware and software; improves operability, maintainability and reliability through immediate access to key data; and, reduces overall life-cycle costs by reducing travel and outage time through remote access to substation information. 5 figs.

PROBE: a feasibility demonstration of substation and distribution automation  

SciTech Connect

Substation and distribution automation has existed for a number of years with varying degrees of sophistication. Recently trial installations have been initiated utilizing digital computer technology and advanced electronics to accomplish automation of certain substation functions. Investigations are also under way of remote meter reading and customer load management. The PROBE project is a research investigation to determine the feasibility of sampling data and creation of a data base to achieve these functions using digital techniques. A key objective of PROBE is to demonstrate the feasibility of utilizing data base information to make sophisticated decisions automatically and achieve a degree of coordination between functions not hitherto attainable. The equipment used, test procedures and results are described. Experience from the PROBE feasibility demonstration and Phase 1 tests show that the described substation and distribution automation implementation techniques are viable.

Pepco's standard 80 MVa substation  

SciTech Connect

As a result of studies made prior to 1960, the Potomac Electric Power Company changes its distribution system from a 4.16 kV primary network to a 13.8 kV radial system, utilizing the 69 kV subtransmission system as the primary supply voltage. The 80 Mva substation design and arrangement were developed as an integral component of this system. Following the philosphy established in the 1930s, the electrical equipment would be completely enclosed within a building. This approach provided a functional as well as attractive substation which could be located in an existing community or in a developing area. The 80 Mva substation building was developed to provide maximum flexibility in appearance and electrical equipment arrangement as well as in engineering, drafting, and construction. Design details and future aspects are discussed.

Switching surge test results ehv substation bus configurations  

SciTech Connect

The industry has been actively engaged in, and has presented many results of, ehv switching surge test programs associated with transmission line designs. It would seem equally important that similar efforts be staged relative to ehv switching surge capabilities of the terminal equipment as it would normally be found in its variety of configurations. Toward this end, a series of switching surge test programs on a number of substation bus configurations was conducted. Particular emphasis was placed on the determination of switching surge characteristics of the air gaps found in ehv substation bus designs. The test data are presented with pertinent data evaluations in an attempt to provide a more refined basis for the application of final judgments to bus designs for 345, 500, and 750 kV substations.

Ground resistance of concrete foundations in substation yards  

SciTech Connect

The reinforced concrete foundations in a substation yard have extensive reinforcing steel which is in metallic connection with the laid ground conductor. The foundations may contribute significantly to the dissipation of the fault and leakage currents. Simple to use equations and graphs are presented in this paper to determine the ground resistance of various types of foundations encountered in substation yards. The validity of the analytical approach has been verified with scale model tests. The ground resistance of the foundations estimated as suggested in the paper can be used to evaluate the role of the foundations as grounding element.

Turnkey substations can make sense. even for large utilities  

SciTech Connect

Large utilities with well-trained engineering staffs seldom consider buying a substation on a turnkey basis, but there are good and justifiable reasons for them to do so. A turnkey substation can reduce manpower requirements and eliminate cash-flow problems, especially when a new technology is involved. The utility also gains the benefit of its supplier's expertise. A turnkey supplier can perform all the planning, design, engineering, and financing functions besides assuming the responsibility to correct any errors made by subcontractors. The turnkey supplier becomes the project manager during construction, installation, testing, and start-up.

Ehv substation equipment challenges both designer and manufacturer  

SciTech Connect

Huge equipment and structures necessary to operate substations at extra-high voltage (ehv) require special design innovations. Because of the phase spacing required more real estate and larger, stronger takeoff structures are necessary. Also, economics (and optimization) becomes a more-important factor in design because of the large investment involved. Because generating plants are increasing steadily in size and are being located more remote from load centers, ehv transmission is becoming more common. Some of the design criteria and costs for ehv-substation equipment that is necessary to terminate the transmission lines at 345 kV and higher voltages are discussed.

Evaluating the availability of electrical substations: A dynamic methodology  

Science Conference Proceedings (OSTI)

This paper proposes a technique for evaluating the availability of substations and switching stations including the average cost of repairs of damaged equipment (corrective maintenance), the impact of disturbances on equipment availability, and the impact of disturbances on the continuity of the service provided by the substation. The approach is based on the concept of disruptive events, sequence-based processes, state graphs and Markov techniques. The paper illustrates the technique by comparing the availability of two possible station layouts. The results clearly show the benefit that can be obtained using this objective method of comparison.

MFTF 230 kV pulsed power substation  

SciTech Connect

The Mirror Fusion Test Facility (MFTF) currently under construction at the Lawrence Livermore Laboratory includes a Sustaining Neutral Beam Power Supply System (SNBPSS) consisting of 24 power-supply sets. The System will operate in long pulses (initially .5 seconds and eventually 30 seconds) at high power (200 MW), which will necessitate a large source of ac power. To meet this requirement, a new 230-kV substation is also being built at LLL. The constraints of cost, equipment protection, short operating lifetime (10 years), and reliability dictated a unique substation design. Its unusual features include provisions for fast fault detection and tripping, a capability for limiting ground fault current, low impedance, and economical design.

The ground resistance of the foot is affected by the limited depth of the gravel layer usually spread over the surface of the soil in substation yards.Equations and graphs given in IEEE Standard 80 to determine this ground resistance are not accurate and give conservative results. This paper presents more accurate equations and graphs for determining the ground resistance of the foot in a substation having a thin surface layer of gravel. Analysis has been made with two models of the foot. In one model the foot is represented by an equivalent circular plate and in the other by an equivalent rectangular plate. Results obtained with these two models and with the IEEE Standard 80 method have been compared.

It makes no sense to perform costly, scheduled outage maintenance work when other equipment is failing because of undetected defects. The following should be included as major elements in an energized testing program: visual inspections; infrared inspection; corona inspection; percent oxygen in gas samples drawn from nitrogen-blanketed transformers; percent total combustible gas in gas samples drawn from nitrogen-blanketed transformers; dissolved gas analysis; oil quality tests; free water in the sample; dissolved water in oil; dissolved metals-in-oil analysis; furfural concentration analysis; SF[sub 6] analysis; battery testing; the substation grounding grid; and protective relays. 4 figs.

Electric Field Modeling of Polymer Insulators in Substations  

Science Conference Proceedings (OSTI)

The use of transmission line suspension class polymer insulators is increasing for a wide range of reasons including lower cost, availability, their lightweight nature, and contamination performance. The expected use of these polymer insulators is on transmission lines; thus this is the application for which manufacturers design and test the recommended corona rings. Numerous suspension polymer insulators are being applied in substations in configurations which have different geometries to the transmissi...

Substation based data interpretation techniques for improved power system management  

Science Conference Proceedings (OSTI)

There is now considerable pressure on electric utilities to operate their systems in the most efficient manner possible and to provide increased quality of service to customers. This pressure, coupled with the decreasing availability of reserve margins dictates that there is a requirement for comprehensive system operation support through, among other things, the provision of quality information relating to the behavior of the primary and secondary systems. This paper will show how the data available within modern substation control and management systems can be exploited in a cost-effective manner, through the implementation of advanced substation functions in an open systems environment. Certain functions which are presently carried out at the control center could be distributed (or partially distributed) to the substation. These functions may provide the utility staff with quality information, which can in turn be used to satisfy the objectives of increasing quality and security of supply, in addition to optimizing the utility`s information, maintenance and asset management functions.

An Integrative Approach to Reliability Analysis of an IEC 61850 Digital Substation  

E-Print Network (OSTI)

In recent years, reliability evaluation of substation automation systems has received a significant attention from the research community. With the advent of the concept of smart grid, there is a growing trend to integrate more computation and communication technology into power systems. This thesis focuses on the reliability evaluation of modern substation automation systems. Such systems include both physical devices (current carrying) such as lines, circuit breakers, and transformers, as well as cyber devices (Ethernet switches, intelligent electronic devices, and cables) and belong to a broader class of cyber-physical systems. We assume that the substation utilizes IEC 61850 standard, which is a dominant standard for substation automation. Focusing on IEC 61850 standard, we discuss the failure modes and analyze their effects on the system. We utilize reliability block diagrams for analyzing the reliability of substation components (bay units) and then use the state space approach to study the effects at the substation level. Case study is based on an actual IEC 61850 substation automation system, with different network topologies consideration concluded. Our analysis provides a starting point for evaluating the reliability of the substation and the effects of substation failures to the rest of the power system. By using the state space methods, the steady state probability of each failure effects were calculated in different bay units. These probabilities can be further used in the modeling of the composite power system to analyze the loss of load probabilities.

Insulation and radio influence dictate design of 650 kV substation  

SciTech Connect

The 650 kV North Substation of Project EHV is marked by three unusual features which differentiate it from the more familiar 230 and 345 kV substations. First, the sheer size of the apparatus, structures, and busses is striking. Second, is the amount of insulation. As represented by insulators and bushings it is proportionally much larger in lower voltage substations. Third, is the absence of sharp protrusions or angles anywhere in the substation, even on the roof of the house where corona loss is measured. Shielding is evident everywhere in the circles or ovals of smooth aluminum tubing.

Single-transformer substation for 500 kV and over  

SciTech Connect

At extra high voltage substations which must meet high reliability requirements, in particular, two autotransformer groups are often installed almost simultaneously independent of the load. As a result, significant capital investment is frozen for long periods, and scarce electrical equipment is utilized inefficiently. Thus, in a number of cases the construction of substations with a single group of single-phase autotransformers is desirable. In this case, on failure of one autotransformer phase the time of subnormal energy output due to disconnection of the substation may reach several hours. The efficiency of extra high voltage substations may be improved significantly by using a proposed circuit for connection of a group of single-phase transformers with a single reserve phase, permitting installation of one group of single-phase transformers at a substation without impairment of reliability. The installation, performance and cost of this transformer arrangement are discussed. It is concluded that the use of single-transformer 500 kV substations with the proposed circuit as distribution substations would, on the one hand, provide sufficient reliability for users and, on the other hand, would make them competitive with 220 to 330 kV substations. In this case the network reliability can be provided by sectionalizing the lines at the site of transformer connection. This circuit can be used with two-sided substation supply. (LCL)

230 kV operation of a substation designed for 115 kV by controlling voltage transients  

SciTech Connect

Arresters applied at the terminals of gas insulated substations have been used successfully for protection from switching and lightning surges. This arrester application for gas insulated substations permits the use of lower insulation levels and therefore more economical substations. In principle, the same technique can be applied to air insulated substations. This paper describes the analysis of transient voltages in a substation designed for 115 kV which is scheduled for operation at 230 kV. Both arrester rating and location are considered in this analysis. It is shown that complete substation protection is possible by addition of both arresters and capacitors.

The Alabama Power Company's power-installed streetlight foundation (SLF) saves 85% of labor costs and is practical as well as economical. After several foundation designs were tried, the multi-helix proved best for swampy terrain. A test of substation structure support began with soil testing to locate any rock on the site. Standard tubular-steel structures with modified baseplates were used. A truck-mounted derrick proved better for installation than a drill rig. Slight corrosive currents are not expected to cause appreciable deterioration to the foundation. (DCK)

A simplified method for calculating the substation grounding grid resistance  

SciTech Connect

A simple and accurate formula for calculating the grounding grid resistance is proposed in this paper. This method is based on a theoretical manipulation of the numerical moment method and of the current image. The formula is dependent on the substation grounding grid design, such as grid depth, grid size, number of meshes, grid-conductor diameter, etc. A comparison study is performed to check the accuracy of the proposed formula with respect to six different formulas and methods in the literature. An excellent agreement was found between the results of this formula and the results of a sophisticated computerized method.

Design, Simulation, and Analysis of Substation Automation Networks  

E-Print Network (OSTI)

Society depends on computer networks for communication. The networks were built to support and facilitate several important applications such as email, web browsing and instant messaging. Recently, there is a significant interest in leveraging modern local and wide area communication networks for improving reliability and performance in critical infrastructures. Emerging critical infrastructure applications, such as smart grid, require a certain degree of reliability and Quality of Service (QoS). Supporting these applications requires network protocols that enable delay sensitive packet delivery and packet prioritization. However, most of the traditional networks are designed to provide best effort service without any support for QoS. The protocols used in these networks do not support packet prioritization, delay requirements and reliability. In this thesis, we focus on the design and analysis of communication protocols for supporting smart grid applications. In particular, we focus on the Substation Automation Systems (SAS). Substations are nodes in the smart grid infrastructure that help the in transportation of power by connecting the transmission and distribution lines. The SAS applications are con figured to operate with minimal human intervention. The SAS monitors the line loads continuously. If the load values are too high and can lead to damage, the SAS declares those conditions as faults. On fault detection, the SAS must take care of the communication with the relay to open the circuit to prevent any damage. These messages are of high priority and require reliable, delay sensitive delivery. There is a threshold for the delay of these messages, and a slight increase in the delay above the threshold might cause severe damages. Along with such high priority messages, the SAS has a lot of background traffic as well. In spite of the background traffic, the substation network must take care of delivering the priority messages on time. Hence, the network plays a vital role in the operation of the substation. Networks designed for such applications should be analyzed carefully to make sure that the requirements are met properly. We analyzed and compared the performance of the SAS under di erent network topologies. By observing the characteristics of the existing architectures, we came up with new architectures that perform better. We have suggested several modi cations to existing solutions that allow significant improvement in the performance of the existing solutions.

A Dual-Supply Buck Converter with Improved Light-Load Efficiency  

E-Print Network (OSTI)

Power consumption and device size have been placed at the primary concerns for battery-operated portable applications. Switching converters gain popularity in powering portable devices due to their high efficiency, compact sizes and high current delivery capability. However portable devices usually operate at light loads most of the time and are only required to deliver high current in very short periods, while conventional buck converter suffers from low efficiency at light load due to the switching losses that do not scale with load current. In this research, a novel technique for buck converter is proposed to reduce the switching loss by reducing the effective voltage supply at light load. This buck converter, implemented in TSMC 0.18 micrometers CMOS technology, operates with a input voltage of 3.3V and generates an output voltage of 0.9V, delivers a load current from 1mA to 400mA, and achieves 54 percent ~ 91 percent power efficiency. It is designed to work with a constant switching frequency of 3MHz. Without sacrificing output frequency spectrum or output ripple, an efficiency improvement of up to 20 percent is obtained at light load.

Digital multimode buck converter control with loss-minimizing synchronous rectifier adaptation  

E-Print Network (OSTI)

Abstract—This paper develops a multimode control strategy which allows for efficient operation of the buck converter over a wide load range. A method for control of synchronous rectifiers as a direct function of the load current is introduced [1]. The function relating the synchronous-rectifier timing to the load current is optimized on-line with a gradient power-loss-minimizing algorithm. Only low-bandwidth measurements of the load current and a power-loss-related quantity are required, making the technique suitable for digital controller implementations. Compared to alternative loss-minimizing approaches, this method has superior adjustment speed and robustness to disturbances, and can simultaneously optimize multiple parameters. The proposed synchronous-rectifier control also accomplishes an automatic, optimal transition to discontinuous-conduction mode at light load. Further, by imposing a minimum duty-ratio, the converter automatically enters pulse-skipping mode at very light load. Thus, the same controller structure can be used in both fixed-frequency pulsewidth modulation and variable-frequency pulse-skipping modes. These techniques are demonstrated on a digitally-controlled 100-W buck converter. Index Terms—Adaptive control, dead-time, digital control, gradient methods, multimode control, optimization methods, pulse skipping, pulsewidth modulated (PWM) power converters, pulsewidth modulation (PWM), synchronous rectifier (SR), variable frequency control.

HEMP-induced transients in electric power substations. Final report  

SciTech Connect

A nuclear detonation in or above the earth`s atmosphere produces an intense electromagnetic pulse (EMP). A large portion of the EMP electromagnetic energy is within the RF spectrum. A detonation at high altitudes above 40 km produces an EMP called high-altitude EMP (HEMP). HEMP is a steep-front short duration transient with a rise time on the order of a few nanoseconds which decays to near zero in less than a microsecond. A single high-altitude burst can subject much of the continental United States to intense HEMP electric fields on the order of tens of kilovolts per meter. The intense transient HEMP will induce fast transients in high-voltage transmission lines and bus structures, instrumentation cables, and control wires in power transmission and distribution (T & D) substations. A system of traveling wave coupling models for a 500 kV substation, including models for the high voltage primary bus, components (circuit breakers, disconnect switches, power transformers, and current and voltage instrument transformers), low voltage control wiring circuits, and a number of conducted and radiated interference coupling modes, had been developed earlier by EPRI. These EPRI served as the baseline for the present HEMP coupling investigations. The HEMP effects on protective relays were assessed for a nominal HEMP environment using several new field coupling models merged with the switching transient data. It is found that a representative solid state relay is unlikely to be damaged or to misoperate by the nominal HEMP threat with a peak field strength of 50 kV/m. However, it is possible for both DC control wires to flash over to ground simultaneously, causing fuses to blow and placing the relay in an inoperative state.

These EPRI served as the baseline for the present HEMP coupling investigations. The HEMP effects on protective relays were assessed for a nominal HEMP environment using several new field coupling models merged with the switching transient data. It is found that a representative solid state relay is unlikely to be damaged or to misoperate by the nominal HEMP threat with a peak field strength of 50 kV/m. However, it is possible for both DC control wires to flash over to ground simultaneously, causing fuses to blow and placing the relay in an inoperative state.

Canby Area Service Project : Substation and Associated Transmission Line : Environmental Assessment.  

DOE Green Energy (OSTI)

Bonneville Power Administration (BPA) provides power to Surprise Valley Electrification Corporation (SVEC) in Modoc County, California. BPA uses PacificCorp's substation and transmission facilities between Alturas and Canby, California to transfer power to SVEC's Canby Substation. In the next year, SVEC expects increased industrial, agricultural, and residential electric loads on their 69-kV transmission system south of Canby. SVEC's substation can accommodate only about 10 percent of the expected additional electric load. BPA's proposed action is intended to meet SVEC's increasing electric load. BPA proposes to meet SVEC's increasing energy load by tapping into BPA's existing BPA Malin-Warner 230-kV transmission line, and building an 7.9-mile transmission line to a new BPA substation. BPA proposes to build the new substation next to the west side of SVEC's Canby Substation (Figure 1). This new substation will allow SVEC to move the additional power over their existing transmission or distribution lines. This report is the environmental assessment of the potential impact of the proposed project. The assessment determined that no environmental impact statement'' is not required.

Assessment of the risk of fatal electric shocks inside a substation and in nearby exposed areas  

SciTech Connect

A simulation approach is elaborated for the risk assessment of fatal electric shocks due to touch and step voltages that are caused inside and around substations by ground faults. The approach suggested takes into account specific effects of ground faults, depending on their location, and various exposures encountered in practice. The fibrillation thresholds and human body impedance values are modelled as random functions to match well with the available experimental data. Several typical cases are analyzed for a substation, as an illustration. The approach developed is intended to serve for a realistic analysis of risks implied by grounding system design of a substation surrounded by exposed areas.

An innovative scale model of a 345-kV substation that can be energized to produce representative electric fields has been developed. The purpose of the model is to determine how changes in substation design and operation affect ground-level voltage gradients. Recent tests of the field strengths predicted by the model and actual voltage gradients at the full-size substation at 150 different pairs of points showed excellent agreement. For 94 percent of the pairs the model error was less than 10 percent. The statistical mean of the absolute values of the discrepancies for all 150 points was only 4.6 percent.

Results of the radiological survey at the former Herring-Hall-Marvin Safe Company (3rd floor), 1550 Grand Boulevard, Hamilton, Ohio (HO001)  

SciTech Connect

At the request of the US Department of Energy (DOE), a group from the Oak Ridge National Laboratory conducted a radiological survey at the former Herring-Hall-Marvin Safe Company (third floor), 1550 Grand Boulevard, Hamilton, Ohio (HO001) in August 1993. The purpose of the survey was to determine whether the property was contaminated with radioactive residues, principally {sup 238}U, derived from the former Manhattan Engineer District project. The survey included gamma scans; direct and transferable measurements of alpha, beta, and gamma radiation levels; and debris sampling for radionuclide analyses. Results of the survey demonstrated {sup 238}U surface contamination in excess of the DOE criteria for surface contamination. The third floor was generally contaminated over 25 percent of its area with isolated spots in the remaining area. Although three isolated spots of contamination were found in areas other than on the third floor (in the same southeastern comer of the facility), they were remediated by sampling. Based on the survey results, this site is recommended for remediation.

Bucking Coil Implementation on PMT for Active Cancelling of Magnetic Field  

SciTech Connect

Aerogel and water Cerenkov detectors were employed to tag kaons for a lambda hypernuclear spectroscopic experiment which used the (e,e'K{sup +}) reaction in experimental Hall C at Jefferson Lab (JLab E05-115). Fringe fields from the kaon spectrometer magnet yielded ~5 Gauss at the photomultiplier tubes (PMT) for these detectors which could not be easily shielded. As this field results in a lowered kaon detection efficiency, we implemented a bucking coil on each photomultiplier tubes to actively cancel this magnetic field, thus maximizing kaon detection efficiency.

A simple approach to improve lightning performance of an uprated substation  

Science Conference Proceedings (OSTI)

This paper presents a simple method to minimize lightning surges entering an uprated or compact substation. A severe lightning stress is caused by a backflashover in close proximity to the substation. Feasibility of uprating is based on the surge arrester technology available at present. However, some aspects of line design offer opportunities in reducing frequency and severity of lightning surges imposed on the substation. The tower surge response adds an inductive overshoot only during the front of the stroke which reduces considerably during the tail. If backflashover does not occur before reflections from adjacent towers arrive, it is unlikely to occur at all. Use of guys and underbuilt ground wires in the limiting distance will produce reflections with larger magnitude and reduce the effective surge impedance of the tower. This would not only reduce backflashover frequency but will also minimize crest and duration of surges entering the substation.

Wood substation design beats out steel. [Conversion of 115-kV to 230 kV substations at Carolina Power and Light Co  

SciTech Connect

Construction plans for voltage conversion of substations can lead to new designs that are economical, reduce outage times, and result in minimum impacts on the environment. In fact, these factors prompted Carolina Power and Light Co. to make one such design its construction standard. Cost of converting a 115-kV distribution source substation to 230 kV is 20 percent less than that of replacing it with one of steel design. And because the conversion creates negligible environmental impact, getting government approval for the project is not a major problem. Steel is relegated to special situations.

Electrical substation service-area estimation using Cellular Automata: An initial report  

SciTech Connect

The service areas for electric power substations can be estimated using a Cellular Automata (CA) model. The CA model is a discrete, iterative process whereby substations acquire service area by claiming neighboring cells. The service area expands from a substation until a neighboring substation service area is met or the substation`s total capacity or other constraints are reached. The CA-model output is dependent on the rule set that defines cell interactions. The rule set is based on a hierarchy of quantitative metrics that represent real-world factors such as land use and population density. Together, the metrics determine the rate of cell acquisition and the upper bound for service area size. Assessing the CA-model accuracy requires comparisons to actual service areas. These actual service areas can be extracted from distribution maps. Quantitative assessment of the CA-model accuracy can be accomplished by a number of methods. Some are as simple as finding the percentage of cells predicted correctly, while others assess a penalty based on the distance from an incorrectly predicted cell to its correct service area. This is an initial report of a work in progress.

Efficiency Analysis of a High Frequency Buck Converter for On-Chip Integration with a Dual-VDD  

E-Print Network (OSTI)

An analysis of the power characteristics of a buck converter is presented in this paper. A high switching frequency is the key design parameter that simultaneously permits monolithic integration and high efficiency. A parasitic model of the buck converter is developed. With this model, a design space is determined that allows integration of active and passive devices on the same die for a target technology. An efficiency of 88.4 % at a switching frequency of 477 MHz is demonstrated for a voltage conversion from 1.2 volts to 0.9 volts while supplying 9.5 amperes average current assuming an 80 nm CMOS technology. The area occupied by the buck converter is 12.6 mm 2. An analytic estimate of the efficiency is shown to be within 2.4 % of simulation at the target design point. Full integration of a high efficiency buck converter on the same die with a dual-VDD microprocessor is shown to be feasible. 1.

Ground potential rise characteristics of urban step-down substations fed by power cables - A practical example  

Science Conference Proceedings (OSTI)

This paper shows some special ground potential rise characteristics of substations fed by power cables. These characteristics were detected during the study of the interconnected ground system of 14 step-down urban substations fed by the 138 kV underground cable network serving the South Zone of Rio de Janeiro city in Brazil. As this type of system is very common in large cities, the subject can be of general interest for the industry. It was verified that when a fault occurs at a ''cable substation'' (a substation fed exclusively by power cables), almost no ground potential effects were detected at the faulted substation or at the other ''cable substations'' of the 138 kV network. However, high values of ground potential occurred at the ''transition substations'' (substations in which the power cables are connected to overhead 138 kV transmission lines, with steel groundwires). That ground potential was enough to produce shocks and equipment damage in certain ''transition substations''. It was verified that this problem has no relation with potential transfer. The paper shows also that the utilization of overhead lines with ACSR groundwires on the initial spans closer to the ''transition substation'' would be enough to avoid the problem. Even if the ACSR conductor is used only at the initial section of one of the lines, a reduction of the problem would be obtained. The paper shows also that the utilization of ACSR ground-wires near the ''transition substations'' contributes to reduce the amount of the copper necessary to control step, touch and mess potentials in these substations. Additional mitigation procedures are also examined in the paper.

Ground grid design changes due to potential rise limits outside substations  

SciTech Connect

To ensure safe grounding for personnel and to provide for correct operation of relays, several design factors are critical to assessing the adequacy of a station ground grid design. These difficult to alter parameters are soil resistivity, clearing times for single line to ground station faults, size and location of the substation, and the magnitude of the single line to ground fault current. These are the critical parameters for the grounding system, leaving the designer with the grid area, grid geometry, wire size, surface material, number of ground rods, and burial depth as the tools for reducing step and touch potentials to adequate levels. Grounding practices for substations are based on maintaining step and touch potentials below the limits described in IEEE-80. Guide for AC Substation Grounding. Recently, requirements to limit step and touch potentials outside the substation perimeter were proposed by particular government agencies in Commonwealth Edison's service territory. This limit imposes design changes that would increase construction costs and prevent locating substation at existing sites. This paper compares the design changes needed to meet lower limits with a standard installation designed according to the IEEE-80 guide.

E-Print Network (OSTI)

Abstract — This paper describes a dual-mode digitallycontrolled buck converter IC for cellular phone applications. An architecture employing internal power management is introduced to ensure voltage compatibility between a singlecell lithium-ion battery voltage and a low voltage integrated circuit technology. Special purpose analog and digital interface elements are developed. These include a ring-oscillator based ADC (ring-ADC), which is nearly entirely synthesizable, robust against switching noise, and has flexible resolution control, and a very low power ring oscillator-multiplexer based Digital PWM generation module (ring-MUX DPWM). The chip, which includes an output power stage rated for 400 mA, occupies 2mm 2 active area in 0.25-µm CMOS. Very high efficiencies are achieved over a load range of 0.1 to 400 mA. Measured quiescent current in PFM mode is 4 µA. I.

Use of standard distribution substation transformers can lead to early failures  

SciTech Connect

Unnecessary outages and transformer failures may result from the use of traditional substation transformers as an economy measure because design variations do not always specify the through-fault and overload characteristics of equipment. Efforts to keep costs down can overlook variations in the strengths and weaknesses of units. Research results at RTE-ASEA here and in Sweden show that previous faults determine a unit's ability to tolerate new failures and that periodic overloading of substation transformers hastens aging and failure. 1 figure, 2 tables.

Discrete-Time Poles and Dynamics of Discontinuous Mode Boost and Buck Converters Under Various Control Schemes  

E-Print Network (OSTI)

Nonlinear systems, such as switching DC-DC boost or buck converters, have rich dynamics. A simple one-dimensional discrete-time model is used to analyze the boost or buck converter in discontinuous conduction mode. Seven different control schemes (open-loop power stage, voltage mode control, current mode control, constant power load, constant current load, constant-on-time control, and boundary conduction mode) are analyzed systematically. The linearized dynamics is obtained simply by taking partial derivatives with respect to dynamic variables. In the discrete-time model, there is only a single pole and no zero. The single closed-loop pole is a linear combination of three terms: the open-loop pole, a term due to the control scheme, and a term due to the non-resistive load. Even with a single pole, the phase response of the discrete-time model can go beyond -90 degrees as in the two-pole average models. In the boost converter with a resistive load under current mode control, adding the compensating ramp has no effect on the pole location. Increasing the ramp slope decreases the DC gain of control-to-output transfer function and increases the audio-susceptibility. Similar analysis is applied to the buck converter with a non-resistive load or variable switching frequency. The derived dynamics agrees closely with the exact switching model and the past research results.

Coordination of a distribution level continuously controlled compensation device with existing substation equipment for long term VAR management  

SciTech Connect

The implementation of a continuously controlled reactive compensation device, such as an SVC or a static condenser'' (STATCON), in a distribution-level substation provides opportunities to improve power quality and reliability due to the speed of response of such a device. Further benefits can be gained by coordinating the reactive compensation device and its related controls with other substation voltage control equipment, such as load tap changing (LTC) transformers and mechanically-switched capacitors. The results presented in this paper illustrate the impact that a [+-] 12 Mvar STATCON can have on a 150 MW, 12.5 kV load bus, in the Commonwealth Edison power system. Three control concepts for various levels of integration of the substation STATCON, LTCs, and mechanically-switched capacitors are presented. With broader application of SVCs and STATCONs at distribution substations, various other control strategies may also evolve.

A procedure for derating a substation transformer in the presence of widespread electric vehicle battery charging  

Science Conference Proceedings (OSTI)

This paper studies the effect of electric vehicle (EV) battery charging on a substation transformer that supplies commercial, residential, industrial, and EV load on a peak summer day. The analysis begins on modeling non-EV load with typical utility load shapes. EV load is modeled using the results from an analytical solution technique that predicts the net power and harmonic currents generated by a group of EV battery chargers. The authors evaluate the amount of transformer derating by maintaining constant daily transformer loss-of-life, with and without EV charging. This analysis shows that the time of day and the length of time during which the EVs begin charging are critical in determining the amount of transformer derating required. The results show that with proper control, EV charging may have very little effect on power system components at the substation level.

Lightning overvoltage protection of the paddock 362-145 kV Gas-Insulated Substation  

SciTech Connect

Backflashovers close to the Paddiock 362-145 kV Gas-Insulated Substation (GIS) have been analyzed with the Electro-Magnetic Transient Program (EMTP) using a frequency dependent multi-conductor system. The severity of the lightning stroke currents were derived based on recent recordings in the eastern United States. Impacts of corona attenuation and distortion were accounted for using a shunt linear model approach. Turn-up effects of both line insulator flashover voltages and surge arrester protective characteristics were represented based on manufacturer's volt-time curves. Wave shaping effects of substation capacitances (ie., PT's transformers, CCPD's) were also modeled. Results show the importance of various modeling details in determining the overvoltages inside the GIS due to close backflashovers, which are caused by lightning strokes with varying intensity. These results are aimed at better evaluation of lightning protection requirements for GIS protected by metal-oxide surge arresters.

Marys Lake 69/115-kV transmission line upgrade and substation expansion projects  

SciTech Connect

Western Area Power Administration (Western) and the Platte River Power Authority (Platte River) propose to upgrade portions of the existing electric transmission and substation system that serves the Town of Estes Park, Colorado. The existing transmission lines between the Estes Power Plant Switchyard and the Marys Lake Substation include a 115,000 volt (115-kV) line and 69,000 volt (69-kV) line. Approximately one mile is a double-circuit 115/69-kV line on steel lattice structures, and approximately two miles consists of separate single-circuit 115-kV and a 69-kV lines, constructed on wood H-Frame structures. Both lines were constructed in 1951 by the US Bureau of Reclamation. The existing transmission lines are on rights-of-way (ROW) that vary from 75 feet to 120 feet and are owned by Western. There are 48 landowners adjacent to the existing ROW. All of the houses were built adjacent to the existing ROW after the transmission lines were constructed. Upgrading the existing 69-kV transmission line between the Marys Lake Substation and the Estes Power Plant Switchyard to 115-kV and expanding the Marys Lake Substation was identified as the most effective way in which to improve electric service to Estes Park. The primary purpose and need of the proposed project is to improve the reliability of electric service to the Town of Estes Park. Lack of reliability has been a historical concern, and reliability will always be less than desired until physical improvements are made to the electrical facilities serving Estes Park.

Lightning protection requirements of SF/sub 6/ substation determined by hybrid simulator. [115/345 kv station  

SciTech Connect

The development of a hybrid computer simulation which can provide the type and quantity of data necessary for determining the behavior of lightning-caused surges traveling through substations is discussed. Results from a specific application on a 115-kV/345-kV station are presented. The results show that the simulation of SF/sub 6/ substations during lightning-caused surges is ideally accomplished by hybrid computer. The quantity of data for complete substation analysis may be gathered efficiently. In addition, digital graphical summaries provide quick insight into substation behavior. The application of this method to simple configurations has shown the previous assumptions must be carefully reviewed. For example, it is shown by computer simulation and analytical hand calculation that the surges with the steepest wave fronts may not produce the highest substation voltages. It is concluded that this hybrid simulation is an excellent tool in the determination of SF/sub 6/ substation response to lightning-caused surges. (LCL)

Substate Tying With Combined Parameter Training and Reduction in Tied-Mixture HMM Design  

E-Print Network (OSTI)

Two approaches are proposed for the design of tied-mixture hidden Markov models (TMHMM). One approach improves parameter sharing via partial tying of TMHMM states. To facilitate tying at the substate level, the state emission probabilities are constructed in two stages or, equivalently, are viewed as a "mixture of mixtures of Gaussians." This paradigm allows, and is complemented with, an optimization technique to seek the best complexity-accuracy tradeoff solution, which jointly exploits Gaussian density sharing and substate tying. Another approach to enhance model training is combined training and reduction of model parameters. The procedure starts by training a system with a large universal codebook of Gaussian densities. It then iteratively reduces the size of both the codebook and the mixing coefficient matrix, followed by parameter re-training. The additional cost in design complexity is modest. Experimental results on the ISOLET database and its E-set subset show that substate tying reduces the classification error rate by over 15%, compared to standard Gaussian sharing and whole-state tying. TMHMM design with combined training and reduction of parameters reduces the classification error rate by over 20% compared to conventional TMHMM design. When the two proposed approaches were integrated, 25% error rate reduction over TMHMM with whole-state tying was achieved.

Environmental Assessment of Proposed Lynch Creek Substation Project : Service to Eatonville and the Ohop Valley.  

SciTech Connect

Bonneville Power Administation (BPA) proposes to construct 3.2 miles of 115-kV transmission line from a tap point on Tacoma City Light's Cowlitz-LaGrande 115-kV line to a new 115/12.5-kV, 15/20/25 MVA substation to be located about 1 mile northwest of Eatonville, adjacent to the Eatonville cutoff road. This plan was selected following initial consideration of five alternative plans for satisfying electrical needs in the project area and following agreement with BPA's customers on a vicinity for the substation site. The vicinity selected is midway between the two load centers and would require the least construction of distribution line. Subsequently, four alternative line routes and two substation sites have been evaluated. These alternatives provide a range of costs, engineering solutions, and potential environmental impacts. This evaluation led to the selection of one line route. This document describes possible environmental impacts of the proposed actions. 7 refs, 9 figs., 5 tabs.

The effect of magnetic field on optimal design of a rigid-bus substation  

SciTech Connect

Substation rigid-bus design involves electrical, mechanical, and structural considerations. In order to integrate these considerations into one document, IEEE in cooperation with ANSI has issued a comprehensive guide for design of substation rigid-bus systems. The design process based on this guide involves substantial manual effort to integrate all types of calculations. This is particularly evident when the computations have to be repeated several times in order to arrive at a more economic design. In an earlier paper the authors presented a mathematical model and computer program which automates the design process. Recently there has been concern expressed about the possible biological effects of low level magnetic fields. In view of this, a new design constraint taking into account the limits imposed on the magnitude of the magnetic field can be added to the design guidelines. In this paper the authors introduce such a constraint and they show how the magnitude of allowable magnetic field at a specified distance from the station buses affects the optimal design of a rigid bus substation.

Investigation of Auxiliary Power Substation 95A4 fault and fire, Portsmouth Gaseous Diffusion Plant, March 24, 1982  

SciTech Connect

On March 24, 1982, an electrical fault and resultant fire in the 480 volt Auxiliary Power Substation 95A4 at the Portsmouth Gaseous Diffusion Plant destroyed that substation. There were no personal injuries, the overall loss was limited to the Substation, and the cost of replacing the Substation with repaired and new components has been estimated at $184,000. At the time of the incident, Goodyear was involved in a project to replace the obsolete 480 volt circuit breaker of the Auxiliary Power System. This project involved the disassembly, refurishing, and reassembly of 480 volt circuit breaker carriages by Goodyear personnel. The fault occurred in a circuit breaker upgraded under this project. The investigation of this accident is reported. The evidence suggests the fault resulted from the improper assembly of an upgraded 480 volt circuit breaker. Compounding the problem and leading to the extensive damage was the failure of the transformer secondary breaker to trip open as designed and interrupt the flow of power to the substation. It is surmised that inadequate testing during preventive maintenance contributed to this condition. Additional factors which may have contributed to the accident included: no requirements for assuring the competence of the electricians who installed the circuit breakers, no specific assembly instructions to the electricians, inadequate procedure instructions, and an inadequate procedure governing operational or load testing of the breaker.

Reduction factor for the ground resistance of the foot in substation yards  

SciTech Connect

Limited thickness of the surface layer of gravel in a substation yard decreases the ground resistance of the foot from its value for the infinite thickness of the surface layer, by reduction factor C. The foot is usually represented by an equivalent circular plate of radius 8 cm. This paper presents method and equations to accurately determine the reduction factor for the circular plate. The equations are valid for any depth of the upper layer. The data are presented in the form of graphs. A simple empirical equation for determining the value of C is also presented.

New fault locating system for air-insulated substations using optical current detector  

Science Conference Proceedings (OSTI)

This paper deals with a newly developed fault locating system. This fault locating system helps to shorten the time required for restoration of service after the occurrence of a busbar fault in an air-insulated distribution substation. Recent optical and electronic technologies allow highly accurate and compact fault locating system, which consists of optical current detectors using Faraday effect and a fault locating processor employing digital data processing technique. The fault location is made by discriminating the direction of zero-sequence currents. Through various tests and field operations it has been confirmed that the system has sufficient performance for practical application.

A formula for resistance of substation grounding grid in two-layer soil  

SciTech Connect

A simple and accurate formula for calculating the resistance of a grounding grid buried in two-layer soil, is proposed in this paper. The formula is derived from the image theory and a novel synthetic asymptote technique. The resulted formula is dependent on both the substation grounding grid design parameters (such as grid size, number of meshes, grid-conductor diameter, grid depth, etc.) and the soil parameters (such as the resistivities of the upper and lower soils). The resistances calculated using the proposed formula are compared to the resistances obtained from a detailed numerical method and the agreement between the results is very good.

Transient performance of substation grounding systems subjected to lightning and similar surge currents  

SciTech Connect

The frequency and time domain performance of a typical substation grounding system subjected to a lightning strike is described and discussed. The computed scalar potentials, electric fields and magnetic fields are presented graphically as a function of spatial coordinate, as a function of time and as a function of both. It is believed that these detailed results have not been published before. First, a double exponential lightning surge current is injected into the center of a square ground grid. This same surge current is then injected at one corner of the grid. The response of the grounding system to the frequency domain electromagnetic spectrum of this signal is computed by a frequency domain electromagnetic field analysis software package. Once all the frequency responses have been computed, the temporal and spatial distributions of the electromagnetic fields inside and near the substation are obtained by an inverse Fourier transformation of all these responses. The results are compared with some well known low frequency results and to recent published work in this area. These results indicate that the performance of the grounding system is significantly dependent on frequency and on the point of impact of the lightning strike.

Construction is proposed of a 115/12.5-kilovolt (kV), 10/12.5-megavolt-ampere (MVA) substation in the Tesuque area and of 9.02 miles of 115-kV overhead transmission line from the Norton Station to the new substation in an area approximately three miles north of Sante Fe, New Mexico. The project would involve the granting of a 100-foot width right-of-way by the Tesuque Pueblo, the construction of the substation on the Tesuque Pueblo Indian Reservation between the Rio Tesuque and New Mexico 85, the addition of a 115-kV breaker bay at Norton Station, and the installation of two underground 12.47-kV distribution feeders to connect to existing ones in the Tesuque area. In addition, the station would be designed to accommodate one future underground 12.47-kV feeder that would terminate at a future distribution line in the Tesuque area. The preferred transmission line route would originate at the Norton Station and proceed east-northeast up Calabasa Arroyo to a point approximately 1.1 miles north of the southwest corner of the Tesuque Pueblo boundary. From this point the route would proceed east to the proposed substation site.

Seminoe-Kortes transmission line/substation consolidation project, Carbon County, Wyoming  

DOE Green Energy (OSTI)

The existing switchyards at Western Area Power Administration's (WESTERN) Seminoe and Kortes facilities, located approximately 40 miles northeast of Rawlines, Carbon County, Wyoming, were constructed in 1939 and 1951, respectively. The circuit breakers at these facilities are beyond or approaching their service life and need to be replaced. In addition, the switchyards have poor access for maintenance and replacement of equipment, and their locations create potential for oil spills into the North Platte River. WESTERN is proposing to consolidate the switchyard facilities into one new substation to provide easier access, restore proper levels of system reliability, and decrease the potential for oil contamination of the river. This environmental assessment (EA) was prepared to evaluate the impacts of the proposed Seminoe-Kortes Consolidation Project. 57 refs., 12 figs., 8 tabs.

Experience in the installation of a microprocessor system for controlling converter units of the Vyborg substation  

SciTech Connect

The experience in the installation of modern digital systems for controlling converter units at the Vyborg converter substation on the basis of advanced microprocessor devices is considered. It is shown that debugging of a control and protection system on mathematical and physical models does not guarantee optimum control of actual converter devices. Examples of advancing the control and protection system are described, the necessity for which has become obvious in tests of actual equipment. Comparison of oscillograms of processes before optimization of the control system and after its optimization and adjustment shows that the digital control system makes it possible to improve substantially the algorithms of control and protection in the short term and without changing the hardware component.

Effects of deteriorated and contaminated substation surface covering layers on foot resistance calculations  

Science Conference Proceedings (OSTI)

ANSI/IEEE Standard 80 is widely used to determine electrical currents flowing through the human body as the result of touch and step voltages near transmission and distribution facilities. This paper shows, however, that significant inaccuracies can occur when the ANSI/IEEE Standard 80 proposed method to calculate foot resistances is applied in substations covered by a thin layer of crushed rock or similar covering layers. In particular, it is shown that the errors obtained by using the infinite series expression of the foot resistance are consistently larger than those produced by the simplified expression for clean and contaminated surface layers. This paper also compares its results with those proposed recently in the literature. It is shown that these recent proposed equations may be subject to major errors under certain conditions. Equivalent Thevenin foot resistances are plotted for various scenarios of clean and contaminated surface covering layers.

Final environmental assessment for vegetation control at VHF stations, microwave stations, electrical substations, and pole yards  

Science Conference Proceedings (OSTI)

Southwestern Power Adm. operates very high frequency (VHF) and microwave radio stations, electrical substations, and pole yards for electric power transmission throughout AR, MO, and OK. Vegetation growth at the stations must be suppressed for safety of operation and personnel. Southwestern has been using a combination of mechanical/manual and herbicide control for this purpose; Federally- mandated reductions in staff and budgetary resources require Southwestern to evaluate all potentially efficient methods for vegetation control. Three alternatives were examined: no action, mechanical/manual control, and (proposed) a combination of mechanical/manual and herbicide control. Environmental impacts on air and water quality, wetlands, wildlife, endangered species, archaeological and other resources, farmland, human health, transportation, etc. were evaluated.

A Bidirectional High-Power-Quality Grid Interface With a Novel Bidirectional Noninverted Buck Boost Converter for PHEVs  

Science Conference Proceedings (OSTI)

Plug-in hybrid electric vehicles (PHEVs) will play a vital role in future sustainable transportation systems due to their potential in terms of energy security, decreased environmental impact, improved fuel economy, and better performance. Moreover, new regulations have been established to improve the collective gas mileage, cut greenhouse gas emissions, and reduce dependence on foreign oil. This paper primarily focuses on two major thrust areas of PHEVs. First, it introduces a grid-friendly bidirectional alternating current/direct current ac/dc dc/ac rectifier/inverter for facilitating vehicle-to-grid (V2G) integration of PHEVs. Second, it presents an integrated bidirectional noninverted buck boost converter that interfaces the energy storage device of the PHEV to the dc link in both grid-connected and driving modes. The proposed bidirectional converter has minimal grid-level disruptions in terms of power factor and total harmonic distortion, with less switching noise. The integrated bidirectional dc/dc converter assists the grid interface converter to track the charge/discharge power of the PHEV battery. In addition, while driving, the dc/dc converter provides a regulated dc link voltage to the motor drive and captures the braking energy during regenerative braking.

Holbrook Substation Superconductor Cable System, Long Island, New York Final Report  

SciTech Connect

The LIPA Superconductor project broke ground on July 4, 2006, was first energized on April 22, 2008 (Earth Day) and was commissioned on June 25, 2008. Since commissioning, up until early March, 2009, there were numerous refrigeration events that impacted steady state operations. This led to the review of the alarms that were being generated and a rewrite of the program logic in order to decrease the hypersensitivity surrounding these alarms. The high temperature superconductor (HTS) cable was energized on March 5, 2009 and ran uninterrupted until a human error during a refrigeration system switchover knocked the cable out of the grid in early February 2010. The HTS cable was in the grid uninterrupted from March 5, 2009 to February 4, 2010. Although there have been refrigeration events (propagated mainly by voltage sags/surges) during this period, the system was able to automatically switch over from the primary to the backup refrigeration system without issue as required during this period. On February 4, 2010, when switching from the backup over to the primary refrigeration system, two rather than one liquid nitrogen pumps were started inadvertently by a human error (communication) causing an overpressure in the cable cooling line. This in turn activated the pressure relief valve located in the grounding substation. The cable was automatically taken out of the grid without any damage to the components or system as a result of signals sent from the AMSC control cabinet to the LIPA substation. The cable was switched back into the grid again on March 16, 2010 without incident and has been operational since that time. Since switching from the backup to the primary is not an automatic process, a recent improvement was added to the refrigeration operating system to allow remote commands to return the system from backup to primary cooling. This improvement makes the switching procedure quicker since travel to the site to perform this operation is no longer necessary and safer since it is now a programmed procedure versus the former written procedure that was still subject to human variation in the process.

The US CGI program has also included development of a power transformer, shunt reactor, voltage- and current-sensing instrumentation, and a line trap, all for 1200-kV application. This paper presents the overall status of development of CGI substation equipment for uhv application in the United States. It describes the major CGI components developed, highlights their key design aspects, indicates the present status of development and testing, and addresses the work remaining to establish final design consepts. The paper also includes 23 references, a number of which have not been widely distributed or included in any of the recently published bibliographies of uhv substation equipment.

A methodology for performance and compatibility evaluation of an all-digital substation protection system  

E-Print Network (OSTI)

A power system protection system consists, at least, of an instrument trans- former, a protective device (relay), and a circuit breaker. Conventional instrument transformers bring currents and voltages from power network levels to much lower scaled-down replicas that serve as input signals to protective relays. The relay's function is to measure input signals (or a relationship among them in some cases) and compare them to defined operating characteristic thresholds (relay settings) to quickly decide whether to operate associated circuit breaker(s). Existing protection systems within a substation are based on a hardwired interface between instrument transformers and protective relays. Recent development of electronic instrument transformers and the spread of digital relays allow the development of an all-digital protection system, in which the traditional analog interface has been replaced with a digital signal connected to digital relays through a digital communication link (process bus). Due to their design, conventional instrument transformers introduce distortions to the current and voltage signal replicas. These distortions may cause protective relays to misoperate. On the other hand, non-conventional instrument transformers promise distortion-free replicas, which, in turn, should translate into better relay performance. Replacing hardwired signals with a communication bus also reduces the significant cost associated with copper wiring. An all-digital system should provide compatibility and interoperability so that different electronic instrument transformers can be connected to different digital relays (under a multi-vendor connection) Since the novel all-digital system has never been implemented and/or tested in practice so far, its superior performance needs to be evaluated. This thesis proposes a methodology for performance and compatibility evaluation of an all-digital protection system through application testing. The approach defines the performance indices and compatibility indices as well as the evaluation methodology.

Results of the Bonneville Power Administration weatherization and tightening projects at the Midway substation residential community  

Science Conference Proceedings (OSTI)

As part of a regional conservation program, the Bonneville Power Administration retrofitted 18 houses at its Midway substation in central Washington and monitored the results for a three year period. The 18 houses were divided into three groups, or cells. During the first year of the project, energy consumption was monitored but no changes were made to the houses. Prior to the second year of the project, Cell 2 received attic and crawlspace insulation, foundation sill caulking, and increased attic ventilation. Cell 3 received these retrofits plus storm windows and doors, and Cell 1 served as the control group. Before the beginning of the project's third year, each house in Cell 1 received 22 hours of infiltration reduction weatherization or house tightening. Each house in Cell 3 received 10 hours of this same type of weatherization. Cell 2 served as the control group for the house doctoring phase of the project. Energy consumption and weather data were monitored for the entire three year period. Before and after each set of retrofits, leakage area measurements were made using blower door fan pressurization, thereby allowing calculation of heating season infiltration rates. An energy use model correlating energy consumption with outside temperature was developed in order to determine improvements to the thermal conductance of the building envelope as a result of the retrofits. Energy savings were calculated based on the results of the energy use model and, as a check on these findings, the Computerized Instrumented Residential Analysis (CIRA) load calculation program developed at Lawrence Berkeley Laboratory provided a theoretical estimate of the savings resulting from the retrofits.

Synchrophasor Measurement Using Substation Intelligent Electronic Devices: Algorithms and Test Methodology  

E-Print Network (OSTI)

This dissertation studies the performance of synchrophasor measurement obtained using substation Intelligent Electronic Devices (IEDs) and proposes new algorithms and test methodology to improve and verify their performance when used in power system applications. To improve the dynamic performance when exposed to sinusoidal waveform distortions, such as modulation, frequency drift, abrupt change in magnitude, etc, an adaptive approach for accurately estimating phasors while eliminating the effect of various transient disturbances on voltages and currents is proposed. The algorithm pre-analyzes the waveform spanning the window of observation to identify and localize the discontinuities which affect the accuracy of phasor computation. A quadratic polynomial signal model is used to improve the accuracy of phasor estimates during power oscillations. Extensive experimental results demonstrate the advantages. This algorithm can also be used as reference algorithm for testing the performance of the devices extracting synchronized phasor measurements. A novel approach for estimating the phasor parameters, namely frequency, magnitude and angle in real time based on a newly constructed recursive wavelet transform is developed. This algorithm is capable of estimating the phasor parameters in a quarter cycle of an input signal. It features fast response and achieves high accuracy over a wide range of frequency deviations. The signal sampling rate and data window size can be selected to meet desirable application requirements, such as fast response, high accuracy and low computational burden. In addition, an approach for eliminating a decaying DC component, which has significant impact on estimating phasors, is proposed using recursive wavelet transform. This dissertation develops test methodology and tools for evaluating the conformance to standard-define performance for synchrophasor measurements. An interleaving technique applied on output phasors can equivalently increase the reporting rate and can precisely depict the transient behavior of a synchrophasor unit under the step input. A reference phasor estimator is developed and implemented. Various types of Phasor Measurement Units (PMUs) and PMU-enabled IEDs (Intelligent Electronic Devices) and time synchronization options have been tested against the standards using the proposed algorithm. Test results demonstrate the effectiveness and advantages.

SciTech Connect

The statement describes the environmental impacts resulting from the construction of a new substation near Shelton, Washington. Land requirements for the new substation would be approximately 1.5 acres and, depending on the final site location chosen, an access road ranging from 200 to 3000 feet would also be required. Alternative sites 1 and 3 would be located on existing right-of-way and would remove 1.5 acres from other potential uses; alternate sites 2 and 4 would remove 1/4 acre of private timberland from production and 1 acre of existing right-of-way from other potential uses. Disturbance to wildlife during construction and loss of habitat associated with the above land requirements will occur. Grading for the substation site and access road will result in increased erosion and potential sedimentation in local streams may occur. Noise impacts will occur during construction.

Modulation and SSR tests performed on the BPA 500 kV thyristor controlled series capacitor unit at Slatt substation  

SciTech Connect

Field experience is reported for a thyristor controlled series capacitor (TCSC) recently commissioned at BPA`s Slatt substation. Subsynchronous resonance tests show that TCSC interactions with shaft dynamics of PGE`s Boardman steam generator are well understood and are effectively avoided by normal TCSC valve firing logic. Modulation tests, performed with the Boardman plant off line, show that the TCSC can be a powerful and responsive actuator for swing damping. Security considerations did not permit lightly damped operation of the controlled plant. Close analysis indicates that the TCSC damping contribution, though small, was measurable. The best estimate is that damping for the McNary mode is 7.33% and 8.55%, for the TCSC damper loop open and closed respectively. TCSC testing and monitoring is facilitated by an advanced interactive measurement network representing BPA`s approach to the information requirements of major control systems.

The value of distributed generation: The PVUSA grid-support project serving Kerman Substation. Interim report, April 1994  

DOE Green Energy (OSTI)

A common practice of electric utilities experiencing transmission and distribution (T and D) system overloads is to expand the substation, add lines, or upgrade equipment, all of which are capital intensive options. In 1988, it was hypothesized that strategically sited photovoltaics (PV) could benefit parts of T and D systems near or at overloaded conditions. An evaluation methodology was developed and applied to a test case (Kerman Substation near Fresno, California). Analytical results suggested that the value of PV to the T and D system could substantially exceed its energy and generation capacity value. The importance of this finding indicated the need for empirical validation. This led to the construction of a 0.5 MW PV demonstration plant by Pacific Gas and Electric Company (PG and E) at Kerman, California as part of the PVUSA (PV for Utility Scale Applications) project. PVUSA is a national public-private partnership that is assessing and demonstrating the viability of utility-scale photovoltaic electric generation systems. The Kerman PV plant, commissioned for commercial operation in June, 1993, is reported to be the first grid-support PV demonstration plant in the world. This Interim Report focuses on validating the technical aspects of grid-support PV. It provides interim validation results for four of the eight identified value components that stack up to make the ``value bar``, and compares them to 1992 Case Study estimates. Results are based on improved technical evaluation methodologies, measured plant performance under a variety of conditions, and long-term plant performance estimated using a validated computer simulation program. This report is not intended to be exhaustive in scope. It does, however, provide a thorough progress update of the validation project. Complete documentation of test procedures, data, and evaluation methods will be presented in the Final Report.

{open_quotes}Secure Bus{close_quotes} disturbance-free power at the utility substation level  

Science Conference Proceedings (OSTI)

Over the last 18 months Public Service Company of New Mexico (PNM), El Camino Real Engineering, Inc. (CRE), Los Alamos National Laboratory (LANL) and Sandia National Laboratories (SNL) have worked on the development of disturbance-free power at the medium voltage substation level. The work resulted in the Secure Bus concept, a system in which a medium voltage bus in a substation is immune to power outages and voltage sags on the utility source. The Secure Bus voltage is also immune to voltage sags resulting from faults on any distribution feeder connected to the bus. The Secure Bus concept originated from work conducted to improve power quality for large high-tech manufacturing facilities, in particular for large semiconductor manufacturing plants. For the demands on quality power of a modern facility conventional equipment is not adequate for protecting the end user. For example, the operation of conventional vacuum breakers during short circuit conditions on a feeder circuit, requiring 3 to 5 cycles for breaker opening, does not allow for fast enough current interruption to avoid a voltage dip on the main bus. A sever voltage sag could result in a shut down of sensitive equipment being supplied by the other feeder circuits, which are connected to the main bus. The circumvent the problem, a fast breaker was introduced which interrupts the short circuit before the current causes a significant voltage disturbance. To make the bus immune also to power disturbances caused by power outages, energy storage is introduced to provide the necessary energy back-up in case the primary source is not available.

Review and evaluation of the Department of Energy's Research and Development Program for 1200-kV transmission and substation equipment  

SciTech Connect

In 1975 the US Department of Energy (DOE), Division of Electric Energy Systems (EES), initiated a program for the research and development (R and D) of 1200-kV transmission and substation equipment with a goal of developing the technology capable of three-phase power transfer of 10 GW. The program was oriented toward compact, compressed-gas-insulated (CGI) component design. The DOE/EES R and D program has encompassed all the major and essential transmission cable, substation apparatus, and specialized instrumentation for a 1200-kV system. It has included more than ten major multiyear research projects and has involved numerous research, development, manufacturing, and testing organizations. This report provides a review and evaluation of the overall DOE/EES 1200-kV R and D program. It includes detailed descriptions of the major projects, their objectives, component and system design direction, and current research status. Future R and D requirements are noted, and commercialization issues are briefly discussed. Research to date has not presented any insurmountable technical obstacles to 1200-kV CGI component design. Thus, although all of the component pieces are not yet available and all of the testing is not yet complete, 1200-kV CGI-based transmission and substation equipment appears to be technically feasible. Although the substation and transmission components under development in this program will not likely reach 1200-kV system commercialization for a number of years, many of the materials and design concepts that have been identified for 1200-kV service are readily applicable to devices rated at lower voltages.

Depending on the final route location chosen, approximately 15 miles of 230-kV double circuit transmission line requiring 5.6 miles of new and 9.4 miles of existing right-of-way would be needed as well as approximately 2500 feet of new access road. Land use affected includes crossing Sacajawea State Park and passig through irrigated cropland and grassland on existing right-of-way, and depending on the alternative route chosen, could cross land proposed for residential development and a proposed interstate highway. An additional 10 to 11 acres of potential cropland would be required for the proposed substation. Disturbance to wildlife during construction would occur and habitat associated with the above land uses would be eliminated. Some erosion and sedimentation would occur. Visual impacts would affect Sacajawea State Park, a proposed highway, and potential residential development land. Noise and other disturbances to residents will occur, primarily during construction.

Big bucks not always needed for new business

Monthly Economic Diversity column for Tri-City Herald (first 2 paragraphs pasted below): I think many of us at one time or another has at least wondered what self-employment would be like. Amidst romantic visions about easygoing schedules and the reduced pressure of not having to answer to someone else, the daydreaming eventually gives way to reality. What would my value proposition be? Where would I start? And would that secret trust fund indeed be revealed to me at the right moment to make it possible? Since for most of us that last question is little more than a pipe dream, the money dilemma is top of mind when it comes to the proposition of starting a business from scratch. But it doesn't have to dig to the bottom of your wallet or your net worth as was recently affirmed in a great Wall Street Journal article about starting successful companies on a shoestring budget.

More bang for your buck: Towards super-adiabatic quantum engines  

E-Print Network (OSTI)

The reversible nature of thermodynamical cycles is an idealisation based on the assumption of perfect quasi-static dynamics. As a consequence of this assumption, ideal engines operate at the maximum efficiency but have zero power. Realistic engines, on the other hand, operate in finite-time and are intrinsically irreversible, implying friction effects at short cycle times. The engineering goal is to find the maximum efficiency allowed at the maximum possible power. In the current technological age, with our ability to manipulate devices at the nanoscale and beyond, one must understand the consequences of engines which operate at the quantum mechanical level. In this domain one cannot avoid the emergence of both quantum and thermal fluctuations which drastically alter the energetics of the cycle. Very recently, it has been shown that the Hamiltonian of a quantum system may be manipulated in such a way as to mimic an adiabatic process via a non-adiabatic shortcut. A surge of experimental progress has demonstrated several of these proposals in the laboratory. In this paper we show that, by utilising shortcuts to adiabaticity in a quantum engine cycle, one can engineer a thermodynamical cycle working at finite power and zero friction. Our findings are elucidated using a harmonic oscillator undergoing a quantum Otto cycle.

ELECTRICAL SUBSTATION RELIABILITY EVALUATION WITH EMPHASIS ON EVOLVING INTERDEPENDENCE ON COMMUNICATION INFRASTRUCTURE.  

Science Conference Proceedings (OSTI)

This study developed a probabilistic methodology for assessment of the reliability and security of electrical energy distribution networks. This included consideration of the future grid system, which will rely heavily on the existing digitally based communication infrastructure for monitoring and protection. Event tree and fault tree methods were utilized. The approach extensively modeled the types of faults that a grid could potentially experience, the response of the grid, and the specific design of the protection schemes. We demonstrated the methods by applying it to a small sub-section of a hypothetical grid based on an existing electrical grid system of a metropolitan area. The results showed that for a typical design that relies on communication network for protection, the communication network reliability could contribute significantly to the frequency of loss of electrical power. The reliability of the communication network could become a more important contributor to the electrical grid reliability as the utilization of the communication network significantly increases in the near future to support ''smart'' transmission and/or distributed generation.

EIS-0483: Estes to Flatiron Substation Transmission Lines Rebuild Project, Larimer County, CO  

Energy.gov (U.S. Department of Energy (DOE))

DOE’s Western Area Power Administration (Western) owns and operates two 16-mile, 115-kilovolt transmission lines on separate rights-of-way between Flatiron Reservoir (near Loveland, Colorado) and the town of Estes Park, Colorado. Western is preparing this EIS to evaluate the environmental impacts of a proposal to upgrade and co-locate these transmission lines, by removing one and abandoning its right-of-way, and rebuilding the other along the existing right-of-way as a double-circuit line (i.e., six conductors per pole). The USDA Forest Service, Arapaho and Roosevelt National Forest, is a cooperating agency in preparing the EIS to support its decision on whether to grant a Special Use Permit for parts of the transmission line located on National Forest lands.

ELECTRICAL SUBSTATION RELIABILITY EVALUATION WITH EMPHASIS ON EVOLVING INTERDEPENDENCE ON COMMUNICATION INFRASTRUCTURE.  

Science Conference Proceedings (OSTI)

The objective of this study is to develop a methodology for a probabilistic assessment of the reliability and security of electrical energy distribution networks. This includes consideration of the future grid system, which will rely heavily on the existing digitally based communication infrastructure for monitoring and protection. Another important objective of this study is to provide information and insights from this research to Consolidated Edison Company (Con Edison) that could be useful in the design of the new network segment to be installed in the area of the World Trade Center in lower Manhattan. Our method is microscopic in nature and relies heavily on the specific design of the portion of the grid being analyzed. It extensively models the types of faults that a grid could potentially experience, the response of the grid, and the specific design of the protection schemes. We demonstrate that the existing technology can be extended and applied to the electrical grid and to the supporting communication network. A small subsection of a hypothetical grid based on the existing New York City electrical grid system of Con Edison is used to demonstrate the methods. Sensitivity studies show that in the current design the frequency for the loss of the main station is sensitive to the communication network reliability. The reliability of the communication network could become a more important contributor to the electrical grid reliability as the utilization of the communication network significantly increases in the near future to support ''smart'' transmission and/or distributed generation. The identification of potential failure modes and their likelihood can support decisions on potential modifications to the network including hardware, monitoring instrumentation, and protection systems.

Effect of increased electric loads on primary substation equipment in 100-B, C, D, DR, F, and H areas  

SciTech Connect

The loading on the primary transformers which step down the 230 kv transmission voltage to a distribution voltage of 13.8 kv, at 100-B-C, 100-D-DR, 100-F, and 100-H Areas will be increased by the synchronous motors now being installed in those areas under Project CG-558. This report summarizes: The changes in electric loads (both kv and power factor) which will result when the new motors are placed in service and certain older motors are withdrawn from service. Electric loads are tabulated in section 4.0 for each area for present conditions, the planned changes and the post-CG-558 conditions. The reduction of distribution voltage during the starting of individual 4500 hp synchronous motors. Since the synchronous motors will be started across the line as induction motors, the starting current will be high, and at a low power factor. Voltage drops are calculated for the starting of a synchronous motor, with one and then with two transformer banks paralleled. The current-interrupting capacity of switchgear vs. the maximum short-circuit current which could occur with separate transformers and with two primary transformers in parallel.

30-MJ superconducting magnetic-energy-storage stabilizing system: an overview  

DOE Green Energy (OSTI)

The 30-MJ superconducting magnetic-energy-storage (SMES) system was devised as an alternate means to modulate the Bonneville Power Administration (BPA) Pacific AC Intertie, a part of the Western US Power System, to prevent undamped power oscillations at 0.35 Hz that were observed to be associated with high power transmission. The SMES system was installed at the BPA Tacoma Substation and successfully operated as an experimental device to initiate tests to determine power system dynamics, to investigate their variability, to assess system response to SMES modulation with a major variable load, and to use SMES to develop stability-control techniques. The system has been operated at frequencies of 0.1 to 1.0 Hz at power levels of +- 8.3 MW with a parallel modulation of the converter bridges and up to 9.5 MW reactive power together with +- 4.5 MW real power in constant VAR mode with buck-boost modulation of the bridges. The coil has been charged at a maximum rate of 11.8 MW. Operation of the SMES system is now under BPA jurisdiction, and all hardware has been transferred to BPA.

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.
