Solid State Sciences Committee (SSSC). Technical progress report, May 1, 1992--April 30, 1993  

SciTech Connect

The Solid State Sciences Committee (SSSC) of the National Research Council (NRC) is charged with monitoring the health of the field of materials science in the United States. Accordingly, the Committee identifies and examines both broad and specific issues affecting the field. Regular meetings, teleconferences, briefings from agencies and the scientific community, the formation of study panels to prepare reports, and special forums are among the mechanisms used by the SSSC to meet its charge. This progress report presents a review of SSSC activities from May 1, 1992 through April 30, 1993. The details of prior activities are discussed in earlier reports. During the above period, the SSSC has continued to track and participate, when requested, in the development of a Federal initiative on advanced materials and processing. Specifically, the SSSC is presently planning the 1993 SSSC Forum (to be cosponsored with the National Materials Advisory Board (NMAB) and the Washington Materials Forum (WMF)). The thrust will be to highlight the Federal Advanced Materials and Processing Program (AMPP). In keeping with its charge to identify and highlight specific areas for scientific and technological opportunities, the SSSC continued to oversee the conduct of a study on biomolecular materials. Preliminary plans also were developed for a study on neutron science, however, further activity is pending. A proposed study on ultrasmall devices has been expanded and absorbed into a broader context; the BPA, with SSSC participation, is preparing to hold a program initiation meeting to evaluate the need for a study on information technology and hardware.

Utility-Scale Solar Power Converter: Agile Direct Grid Connect Medium Voltage 4.7-13.8 kV Power Converter for PV Applications Utilizing Wide Band Gap Devices  

SciTech Connect

Solar ADEPT Project: Satcon is developing a compact, lightweight power conversion device that is capable of taking utility-scale solar power and outputting it directly into the electric utility grid at distribution voltage levelseliminating the need for large transformers. Transformers step up the voltage of the power that is generated by a solar power system so it can be efficiently transported through transmission lines and eventually stepped down to usable voltages before it enters homes and businesses. Power companies step up the voltage because less electricity is lost along transmission lines when the voltage is high and current is low. Satcons new power conversion devices will eliminate these heavy transformers and connect a utility-scale solar power system directly to the grid. Satcons modular devices are designed to ensure reliabilityif one device fails it can be bypassed and the system can continue to run.

Operation of a long-term transient monitoring system in a 138-KV and a 500-KV substation  

SciTech Connect

This paper describes the operating performance of automatic transient monitoring laboratories designed to capture fault and transient data on power systems. Laboratories were installed in a 138-kV and a 500-kV substation and operated for more than 25,000 hours over a three-year period. Recorded during this period were 341 events consisting of lightning, switching, and fault transients. These results provide invaluable data on actual transients in power systems to aid power system equipment designers.

1200-kV future seen; automated distribution dangers  

SciTech Connect

A major problem facing the electric-utility industry concerns power-transmission corridors. The corridors serving the nation's power needs may not be available in sufficient numbers to meet growing electricity demand. The difficulty in locating new power corridors will necessitate the transmission of increased power along pathways already available. The possibility of open-transmission systems going to 1200 kV is being researched at Westinghouse Electric Corporation. While much of the technology for 1200-kV transmission is being demonstrated currently (such as transformers, puffer-breakers, lightning arrestors, and reactors), the public fear of low-level radiation and excessive noise may make construction of 1200-kV open substations near the load virtually impossible. The implications of not having sufficient load capability to meet demand concern Westinghouse officials. The possibility of involuntary power rationing could require social and political solutions instead of technical ones. (SAC)

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.

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.

Survey of Magnetic Fields Near BPA 230-kV and 500-kV Transmission Lines.  

Science Conference Proceedings (OSTI)

The purpose of this study was to characterize typical levels and variability of 60Hz magnetic fields at the centerline and edge of right-of-way of Bonneville Power Administration (BPA) 230-kV and 500-kV transmission lines. This was accomplished by taking magnetic field measurements at over 800 spans in Oregon and Washington. The spans were sampled using a stratified random sampling procedure with region (East vs. West), voltage (230-kV vs 500-kV), and circuit configuration as strata. There were five different circuit configuration groups for each region/voltage category requiring a total of 200 strata. Magnetic field measurements were taken at 13 locations under each span using an EMDEX-C as a survey meter. Additional information recorded for each span included conductor height (at 10 locations), right-of-way width, longitudinal and lateral slope, time of day, vegetation, terrain, weather conditions, temperature, wind speed, span length and presence of other lines in the corridor. 9 refs., 17 figs., 26 tabs.

A 50 kV solid state multipulse kicker modulator  

DOE Green Energy (OSTI)

Performance requirements, design concepts, and test results for a prototype multipulse kicker modulator based on solid-state switches and a voltage-adding transformer topology are described. Tape-wound cores are stacked to form the transformer primary windings and a cylindrical pipe that passes through the circular inner diameters of the cores serves as the secondary winding of the step-up transformer. Boards containing MOSFET switches, trigger circuitry, and energy-storage capacitors plug into the core housings. A 50 kV prototype modulator that meets most of the facility requirements has been designed, fabricated, and tested at LLNL. More recent work has been concerned with designing and testing cores and boards with the full volt-second capability needed for 24-pulse operation. Results of the 50 kV prototype tests, preliminary tests of the full-volt-second cores and boards, and future development needs are described.

CEBAF 200 kV Inverted Electron Gun  

Science Conference Proceedings (OSTI)

Two DC high voltage GaAs photoguns have been built at Jefferson Lab based on a compact inverted insulator design. One photogun provides the polarized electron beam at CEBAF and operates at 130 kV bias voltage. The other gun is used for high average current lifetime studies at a dedicated test facility and has been operated at bias voltage up to 225 kV. The advantages of higher DC voltage for CEBAF include reduced space-charge emittance growth and the potential for prolonged photocathode lifetime. However, a consequence of operating at higher voltages is the increased likelihood of field emission or breakdown, both of which are unacceptable. Highlights of the R&D studies leading toward a production 200keV GaAs photogun for CEBAF will be presented.

765kV Transmission line Voltage gradient  

E-Print Network (OSTI)

Corona ring Transmission lines Nowadays, due to the ever increasing energy consumption and power supply optimization, it is required to construct new power plants, substations and transmission lines. In Iran, also, because of increasing demand for electrical energy, for a significant power loss reduction in power transmission over long distances, and to construct high transmission lines that lead to reduction in the economic costs of transmission lines, the transmission lines must be considered at extra high voltage (EHV) levels. These EHV levels should be compared with the low voltage levels in order to extract the benefits. Therefore, in this paper, a review has been conducted on the types of 765 kV transmission lines used in different countries and a comparison between them and the low voltage levels have been performed. Accordingly, the advantages of EHV transmission lines are summarized. Finally, designing a line of 765 kV single-circuit with 6 conductors per bundle based on existing standards is presented.

Design of the Atlas 240 kV Marx modules  

DOE Green Energy (OSTI)

A prototype 240 kV, oil-insulated Marx module has been designed and constructed at the Los Alamos National Laboratory (LANL). The prototype will be used for testing and certifying the design of the Marx module and certain components, including the closing switches, series resistor, and the capacitors themselves. The prototype will also be used to evaluate proposed mechanical systems designs. Information gained from the construction and testing of the 4-capacitor prototype will be folded into the design of the 16-capacitor maintenance unit. The prototype module consists of four 60 kV capacitors, two closing switches, one shunt resistor, and one series resistor. Cables are used to deliver the current to a dummy load scaled to match Atlas system parameters. The Marx unit is contained in a structure made from G-10, suspended from a steel frame that also serves to support components of the trigger, charging, and control system. Appropriate safety and charging systems are an integral part of the prototype design.

Solid-State Fault Current Limiter Development : Design and Testing Update of a 15kV SSCL Power Stack  

Science Conference Proceedings (OSTI)

ABSTRACT The Solid-State Fault Current Limiter (SSCL) is a promising technology that can be applied to utility power delivery systems to address the problem of increasing fault currents associated with load growth. As demand continues to grow, more power is added to utility system either by increasing generator capacity or by adding distributed generators, resulting in higher available fault currents, often beyond the capabilities of the present infrastructure. The SSCL is power-electronics based equipment designed to work with the present utility system to address this problem. The SSCL monitors the line current and dynamically inserts additional impedance into the line in the event of a fault being detected. The SSCL is based on a modular design and can be configured for 5kV through 69kV systems at nominal current ratings of 1000A to 4000A. Results and Findings This report provides the final test results on the development of 15kV class SSCL single phase power stack. The scope of work included the design of the modular standard building block sub-assemblies, the design and manufacture of the power stack and the testing of the power stack for the key functional tests of continuous current capability and fault current limiting action. Challenges and Objectives Solid-State Current Limiter technology impacts a wide spectrum of utility engineering and operating personnel. It addresses the problems associated with load growth both at Transmission and Distribution class networks. The design concept is pioneering in terms of developing the most efficient and compact power electronics equipment for utility use. The initial test results of the standard building blocks are promising. The independent laboratory tests of the power stack are promising. However the complete 3 phase system needs rigorous testing for performance and reliability. Applications, Values, and Use The SSCL is an intelligent power-electronics device which is modular in design and can provide current limiting or current interrupting capabilities. It can be applied to variety of applications from distribution class to transmission class power delivery grids and networks. It can also be applied to single major commercial and industrial loads and distributed generator supplies. The active switching of devices can be further utilized for protection of substation transformers. The stress on the system can be reduced substantially improving the life of the power system. It minimizes the voltage sag by speedy elimination of heavy fault currents and promises to be an important element of the utility power system. DOE Perspective This development effort is now focused on a 15kV system. This project will help mitigate the challenges of increasing available fault current. DOE has made a major contribution in providing a cost effective SSCL designed to integrate seamlessly into the Transmission and Distribution networks of today and the future. Approach SSCL development program for a 69kV SSCL was initiated which included the use of the Super GTO advanced semiconductor device which won the 2007 R&D100 Award. In the beginning, steps were identified to accomplish the economically viable design of a 69kV class Solid State Current Limiter that is extremely reliable, cost effective, and compact enough to be applied in urban transmission. The prime thrust in design and development was to encompass the 1000A and the 3000A ratings and provide a modular design to cover the wide range of applications. The focus of the project was then shifted to a 15kV class SSCL. The specifications for the 15kV power stack are reviewed. The design changes integrated into the 15kV power stack are discussed. In this Technical Update the complete project is summarized followed by a detailed test report. The power stack independent high voltage laboratory test requirements and results are presented.

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.

CEBAF 200 kV Inverted Electron Gun  

Science Conference Proceedings (OSTI)

Two DC high voltage GaAs photoguns have been built at Jefferson Lab based on a compact inverted insulator design. One photogun provides the polarized electron beam at CEBAF and operates at 130 kV bias voltage. The other gun is used for high average current lifetime studies at a dedicated test facility and has been operated at bias voltage up to 225 kV. The advantages of higher DC voltage for CEBAF include reduced space-charge emittance growth and the potential for prolonged photocathode lifetime. However, a consequence of operating at higher voltages is the increased likelihood of field emission or breakdown, both of which are unacceptable. Highlights of the R&D studies leading toward a production 200keV GaAs photogun for CEBAF will be presented.

Tennessee Valley Authority Eagle Bend 161-kV delivery point environmental assessment  

Science Conference Proceedings (OSTI)

Eagle Bend is an area located in a bend of the Clinch River about one mile southeast of Clinton, Tennessee, in Anderson County. This area, including an industrial park, is supplied electric power by the Clinton Utilities Board (UB) through its 69-kV system, which is in turn supplied by TVA over a 69-kV transmission line from Norris Hydro Plant. Studies of the power supply in the area indicate that there will likely be significant load growth both in the Clinton area in general and the industrial park in particular. Studies further show that if this new load is supplied at 69-kV, the TVA transformer at Norris Hydro which supplies this load will be overloaded by the summer of 1993 and no feasible alternate source which would maintain the quality and reliability of the power delivered to the Clinton system exists to accept this load. Clinton UB also needs to transfer load from its Clinton substation in the same time period to prevent overloading. Additional studies and consultation between TVA and Clinton UB have indicated that the best solution to this problem is to supply this load at 161-kV at a new delivery point for Clinton UB. This would require the construction of a new 161/13-kV substation by Clinton UB and the construction by TVA of a new 161-kV transmission line to connect this substation to the existing TVA 161-kV transmission system.

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.

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.

Field Demonstration of a 24-kV Superconducting Cable at Detroit Edison  

SciTech Connect

Customer acceptance of high temperature superconducting (HTS) cable technology requires a substantial field demonstration illustrating both the system's technical capabilities and its suitability for installation and operation within the utility environment. In this project, the world's first underground installation of an HTS cable using existing ductwork, a 120 meter demonstration cable circuit was designed and installed between the 24 kV bus distribution bus and a 120 kV-24 kV transformer at Detroit Edison's Frisbie substation. The system incorporated cables, accessories, a refrigeration system, and control instrumentation. Although the system was never put in operation because of problems with leaks in the cryostat, the project significantly advanced the state-of-the-art in the design and implementation of Warm Dielectric cable systems in substation applications. Lessons learned in this project are already being incorporated in several ongoing demonstration projects.

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.

Defective insulators in live working on a 550kV compact steel lattice tower  

Science Conference Proceedings (OSTI)

Research was conducted to determine the minimum number of healthy insulator units needed to ensure worker safety in live working on a compact 550 kV steel lattice tower. A large variety of worksite conditions was investigated. Test results confirm the conservative nature of the CIGRE formula for defective insulator units, and modifications to the formula are suggested. The recommended number of healthy units is 12 in a string of 24 units for the case of live work on the compact 550 kV tower, when the Portable Protective Gap (PPG) is used. Adjustment for altitude should be made above 900 m (3,000 ft).

Estimated cost of the project is $37.8 million. The new line and substation facilities would provide a backup transmission path, satisfy the long-term needs in meeting the energy requirements, improve system reliability, improve system stability for the Craig and Hayden generating stations, and leave the existing 115-kV and 138-kV lines in operation to provide additional transmission capacity that would function as backup transmission during an outage on another line. Minute amounts of lands would be displaced. Construction activities would disturb critical ranges for elk and mule deer, elk calving areas, and the mating and nesting areas of greater sandhill cranes, great blue herons, sage grouse, golden eagles, and prairie falcons. Management of timberland would damage natural vegetation. The line would traverse 3.1 miles of flood-prone area, and as many as three transmission towers would lie within the floodplain of the Colorado River. The visual quality of land crossed by the line would be degraded somewhat.

Device Performance  

DOE Green Energy (OSTI)

In the Device Performance group, within the National Center for Photovoltaic's Measurements and Characterization Division, we measure the performance of PV cells and modules with respect to standard reporting conditions--defined as a reference temperature (25 C), total irradiance (1000 Wm-2), and spectral irradiance distribution (IEC standard 60904-3). Typically, these are ''global'' reference conditions, but we can measure with respect to any reference set. To determine device performance, we conduct two general categories of measurements: spectral responsivity (SR) and current versus voltage (I-V). We usually perform these measurements using standard procedures, but we develop new procedures when required by new technologies. We also serve as an independent facility for verifying device performance for the entire PV community. We help the PV community solve its special measurement problems, giving advice on solar simulation, instrumentation for I-V measurements, reference cells, measurement procedures, and anomalous results. And we collaborate with researchers to analyze devices and materials.

Grand Coulee - Bell 500-kV Transmission Line Project, Draft Environmental Impact Statement  

Science Conference Proceedings (OSTI)

BPA is proposing to construct a 500-kilovolt (kV) transmission line that would extend approximately 84 miles between the Grand Coulee 500-kV Switchyard, near Grand Coulee Dam, and the Bell Substation, in Mead just north of Spokane. The new line would cross portions of Douglas, Grant, Lincoln, and Spokane counties. In addition to the transmission line, new equipment would be installed at the substations at each end of the new line and at other facilities. The proposed action would remove an existing 115-kV transmission line and replace it with the new 500-kV line on existing right-of-way for most of its length. Additional right-of-way would be needed in the first 3.5 miles out of the Grand Coulee Switchyard to connect to the existing 115-kV right-of-way. Since the mid-1990s, the transmission path west of Spokane, called the West of Hatwai transmission pathway, has grown increasingly constrained. To date, BPA has been able to manage operation of the path through available operating practices, and customer needed have been met while maintaining the reliability of the path. however, in early 2001, operations showed that the amount of electricity that needs to flow from east to west along this path creates severe transmission congestion. Under these conditions, the system is at risk of overloads and violation of industry safety and reliability standards. The problem is particularly acute in the spring and summer months because of the large amount of power generated by dams east of the path. Large amounts of water cannot be spilled during that time in order for BPA to fulfill its obligation to protect threatened and endangered fish. The amount of power that needs to move through this area during these months at times could exceed the carrying capacity of the existing transmission lines. In additional capacity is not added, BPA will run a significant risk that it will not be able to continue to meet its contractual obligations to deliver power and maintain reliability standards that minimize risks to public safety and to equipment. BPA is considering two construction alternatives, the Agency Proposed Action and the Alternative Action. The Alternative Action would include all the components of the Preferred Action except a double-circuit line would be constructed in the Spokane area between a point about 2 miles west of the Spokane River and Bell Substation, a distance of about 9 miles. BPA is also considering the No Action Alternative.

Proposed Four Corners-Ambrosia-Pajarito 500 kV transmission project. Draft environmental statement  

SciTech Connect

The Public Service Company of New Mexico proposes to construct and operate a 500 kV alternating current (ac) transmission line in the northwestern portion of New Mexico. The proposed line will extend from the Four Corners Power Plant to Ambrosia Station to a proposed Pajarito Station west of Albuquerque, NM. The proposed line will be approximately 173 miles in length. Construction of the 500 kV transmission line will adversely impact soils, vegetation, visual resources, and possibly in an indirect manner, the cultural resources in the area. These adverse impacts may be made minimal by the practice of erosion protection measures, revegetation, and a sound cultural resource management plan. There will be no appreciable impacts, adverse or otherwise in regard to surface or subsurface water by the construction or operation of the proposed transmission line. No adverse effects may be anticipated in regard to communities or social services. Economic impacts in the area will be short-term and should prove beneficial for the duration of the project. Construction and operation of this line will be beneficial in providing needed additional bulk transmission capacity between the Four Corners Plant and Albuquerque and bulk transmission support to the local western New Mexico area.

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)

Proposed Norton-Tesuque 115 kV overhead transmission line and substation in Sante Fe, New Mexico  

SciTech Connect

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.

A frequency domain model for 3 kV dc traction dc-side resonance identification  

SciTech Connect

Frequency-dependent effects in railway traction power systems arise from the impedance of substation and locomotive line filters and the traction line. Harmonic noise from traction drives and substations can excite resonances and produce overcurrent or overvoltage conditions at critical points in the network. In this paper, the harmonic feeding impedances of a 3 kV DC traction system seen from the rectifier substation, locomotive drive converter and pantograph terminals are presented. Several substation and locomotive filters are considered with a frequency-dependent traction line. Resonances attributed to the substation filter, locomotive filter and traction line are separate and distinct, the line introducing poles and zeros in the audio frequency (AF) range which vary in frequency and magnitude with locomotive position.

Weld-Windsor 115-kV Transmission Line Project, Weld County, Colorado  

Science Conference Proceedings (OSTI)

The Western Area Power Administration is proposing to rebuild a 3.0 mile segment of the existing Flatiron-Weld 115-kV transmission line in Weld County. The line would be reconductored with new conductor on new wood pole double circuit structures. The new structures would support a double circuit transmission line configuration. The first circuit would be owned by Western and the second by Public Service Company of Colorado (PSCO). Alternatives considered included no action, constructing PSCO`s circuit on new right-of-way, and reconductoring Western`s existing line on the same structures. The proposed action was selected because it provided an opportunity to share structures with PSCO and, overall, would minimize costs and environmental impacts. The environmental assessment identifies minor effects on existing natural or human resources and minor benefits for agricultural operations.

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.

Final environmental assessment: Los Reales 115 kV transmission line alternative routes  

Science Conference Proceedings (OSTI)

The Central Arizona Project (CAP) was authorized as a part of the Colorado River Basin Project Act (Public Law 90-537) on September 30, 1968. The primary purpose of the CAP is to furnish water for agricultural, municipal, and industrial uses in central and southern Arizona, and western New Mexico. Due to its magnitude, the CAP is divided into several major features serving separate but interrelated functions. The Tucson Aqueduct Phase B pumping plants were designed and constructed to operate on a looped power system. The entire looped power system, including two switching stations and connecting 115-kv transmission lines, was identified in the FEIS and approved for construction in the Secretary of Interior's Record of Decision dated September 24, 1985. The loop begins in the vicinity of the Twin Peaks Pumping Plant -- the northernmost Phase B pumping station, at the Rattlesnake Switching Station. All of the looped power system has been constructed with the exception of the switching station and portion of transmission line proposed to be constructed in this project. Without construction of this final portion of the looped power system, the Phase B pumping plants will not be able to operate normally without negatively affecting nearby power sources. The CAP will also not be able to provide the reliability necessary for municipal water systems dependent upon CAP water. The purpose of this EA is to describe impacts that would result from relocating the Los Reales 115-kV transmission line, and possibly the switching station, originally identified in the FEIS. It should be mentioned the Department of Energy will complete a separate NEPA review.

Environmental assessment: Coolidge-Saguaro 115-kV rehabilitation, Pinal County, Arizona  

Science Conference Proceedings (OSTI)

This Environmental Assessment (EA) presents an analysis of the environmental impacts of the proposed rehabilitation of 29.6 miles of the Coolidge-Saguaro 115-kV transmission line. The project area is in Pinal County, Arizona. The proposal involves reconductoring the line with larger conductor, replacement of deteriorated structures, and replacement of damaged insulators. The proposed action is being considered in order to increase the safety and reliability of this line. The alternative of no action is also addressed in this EA. The proposed action would have insignificant impacts on wildlife, vegetation or other natural resources. There would be no impacts on floodplains or wetlands. The major impact would be on agricultural crops but much of this can be minimized by the timing of construction. There are no conflicts with county or local planning projects. No cultural resources will be affected by the proposed action. The no action alternative would not correct the potential safety hazard or reliability problems of the existing line.

DOE Green Energy (OSTI)

This paper provides the performance data of Atlas plastic capacitors as supplied by Maxwell Technologies and Aerovox Corporation. The fiberglass cases at 13 inches high by 29 inches wide and 28 inches in depth with a 2 inch by 18 inch bushing on each end. Two styles of the 33.5uF capacitors have been evaluated for Atlas use, a conventional paper-foil and a self-healing metalized-paper and plastic dielectric design. A test program to capacitor failure, is being used to evaluate capacitor lifetime at full voltage (60 kV) and a nominal 15% reversal. With the Atlas parameters, peak currents of {approximately} 340 kA are realized. In anticipation of faults, capacitors are capable, specified, and tested for 700 kA performance. Accurate methods are also utilized to determine capacitor inductance, less than 20 nH. The results of the various capacitor testing programs will be presented in addition to future directives for their R and D efforts.

Environmental Assessment of the Gering-Stegall 115-kV Transmission Line Consolidation Project, Scotts Bluff County, Nebraska  

SciTech Connect

The Department of Energy (DOE), Western Area Power Administration (Western) proposes to consolidate segments of two transmission lines near the Gering Substation in Gering, Nebraska. The transmission lines are both located in Scotts Bluff County, Nebraska. The transmission lines are both located in Scotts Bluff County, Nebraska, within the city of Gering. Presently, there are three parallel 115-kilovolt (kV) transmission lines on separate rights-of-way (ROW) that terminate at the Gering Substation. The project would include dismantling the Archer-Gering wood-pole transmission line and rebuilding the remaining two lines on single-pole steel double circuit structures. The project would consolidate the Gering-Stegall North and Gering-Stegall South 115-kV transmission lines on to one ROW for a 1.33-mile segment between the Gering Substation and a point west of the Gering Landfill. All existing wood-pole H-frame structures would be removed, and the Gering-Stegall North and South ROWs abandoned. Western is responsible for the design, construction, operation, and maintenance of the line. Western prepared an environmental assessment (EA) that analyzed the potential environmental impacts of the proposed construction, operation, and maintenance of the 115-kV transmission line consolidation. Based on the analyses in the EA, the DOE finds 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 of 1969 (NEPA).

Roseville Direct Service 230 kV Transmission Line Project, Sacramento and Placer Counties, California: Environmental assessment  

SciTech Connect

At present, the only transmission line serving the City of Roseville is operated by Pacific Gas and Electric Company (PG and E), which serves the City's Berry Street substation with a 60-kV circuit from the company's own Atlantic Street substation. Western pays wheeling charges to PG and E for use of their lines to deliver power to its customers which cannot be served directly. PG and E has informed Roseville that additional system facilities are required to meet the City's firm transmission requirements in excess of 69 megawatt peak. They proposed to build a new 230-kV line and transformer bank at a cost of $10.9 million which the City would have to pay, in addition to the wheeling charges Western would be charged to use the PG and E line. The City's preferred alternative is to have Western construct a direct 239-kV service from its Elverta substation to the Berry Street substation. This would save the city money in construction capital cost, result in more transmission capacity and eliminate the present wheeling costs charged to Western. Mitigation recommendations are included.

Big George to Carter Mountain 115-kV transmission line project, Park and Hot Springs Counties, Wyoming. Environmental Assessment  

SciTech Connect

The Western Area Power Administration (Western) is proposing to rebuild, operate, and maintain a 115-kilovolt (kV) transmission line between the Big George and Carter Mountain Substations in northwest Wyoming (Park and Hot Springs Counties). This environmental assessment (EA) was prepared in compliance with the National Environmental Policy Act (NEPA) and the regulations of the Council on Environmental Quality (CEQ) and the Department of Energy (DOE). The existing Big George to Carter Mountain 69-kV transmission line was constructed in 1941 by the US Department of Interior, Bureau of Reclamation, with 1/0 copper conductor on wood-pole H-frame structures without an overhead ground wire. The line should be replaced because of the deteriorated condition of the wood-pole H-frame structures. Because the line lacks an overhead ground wire, it is subject to numerous outages caused by lightning. The line will be 54 years old in 1995, which is the target date for line replacement. The normal service life of a wood-pole line is 45 years. Under the No Action Alternative, no new transmission lines would be built in the project area. The existing 69-kV transmission line would continue to operate with routine maintenance, with no provisions made for replacement.

Operated device estimation framework  

E-Print Network (OSTI)

Protective device estimation is a challenging task because there are numerous protective devices present in a typical distribution system. Among various protective devices, auto-reclosers and fuses are the main overcurrent protection on distribution systems. Operation of a protective device in response to a particular fault condition depends upon the protective devices operating behavior and coordination of various such protective devices. This thesis presents the design and implementation of a protective device estimation algorithm which helps in identifying which protective devices have operated to clear a short circuit condition. The algorithm uses manufacturers device details, power quality data measured from substation monitoring devices and power system event features estimated using existing DFA algorithms. The proposed technique can be used to evaluate coordination of these protective devices and helps in locating a fault in a distribution system feeder. This approach is independent of feeder topology and could be readily used for any distribution system. The effectiveness of this algorithm is verified by simulated and actual test data. Suggestions are included for future research and application by electric utilities.

Characteristics of Gafchromic XRQA2 films for kV image dose measurement  

SciTech Connect

Purpose: In this study, the relevant characteristics of the new Gafchromic XRQA2 film for its application in measuring kV cone beam computed tomography (CBCT) image doses were thoroughly investigated. Methods: The film was calibrated free in air to air kerma levels between 0 and 9 cGy using 120 kVp photon beams produced by the x-ray volume imager. Films were scanned using transmission and reflection scanning modes with the Epson Expression 10000 XL flat-bed document scanner. The impact of film size, region of interest for the analysis, scan uniformity, scan resolution, scan orientation and alternate scanning sides on the analysis process were investigated. Energy dependence, postirradiation growth of reflectance with time and irradiation angular dependence of the film were tested at different air kerma levels. Results: The net reflectance changed by {approx}3% when the size of the film piece changed from 1 cm x 2 cm to 10 cm x 11 cm and changed by {approx}1% when ROI changed from 0. 7 cm x 0. 7 cm to 8 cm x 8 cm, suggesting a good uniformity of the film. The film was successfully analyzed using the transmission scanning mode, calibration curves from both transmission and reflection scanning modes showed similar behavior. The calibration uncertainty was somewhat lower when the film was scanned using reflection mode (6% and 8% for reflection and transmission modes, respectively.) Higher scanning resolution came with increasing calibration uncertainty. The calibration uncertainty for reflection and transmission modes increased from {approx}3.5% to 7% and from {approx}3.5% to 9%, respectively when scanning resolution was changed from 50 to 400 dpi. Scanning the film on alternate sides using transmission mode led to variation of 16%-19% in the net optical density at doses commonly used for CBCT procedures. The film response changed by almost 10% when it was exposed to beams of two different energies (100 and 120 kVp.) Other features of the film such as film orientation, postexposure growth, and irradiation angular dependence were also investigated. Conclusions: The size of film piece and analysis ROI used for calibration slightly affected the film response. Both transmission and reflection scanning modes can be used to analyze the Gafchromic XRQA2, with the reflection mode having a somewhat lower calibration uncertainty. Scanning films on alternate sides using transmission mode significantly affects the optical density. The film response was shown to be energy dependent. The films reached stability in about 6 h after exposure. The film response was proven to be independent of irradiation angle except when the beam is parallel to the film surface.

OPERATIONAL RESULTS OF THE SPALLATION NEUTRON SOURCE (SNS) POLYPHASE CONVERTER-MODULATOR FOR THE 140 KV KLYSTRON RF SYSTEMS  

SciTech Connect

This paper describes the first operational results of the 140 kV, 1 MW average, 11 MW peak, zero-voltage-switching, 20 kHz polyphase bridge, boost converter-modulator for klystron pulse application. The DC-DC converter derives the buss voltages from a standard 13.8 kV to 2100 Y substation cast-core transformer. Energy storage and filtering is provided by self-clearing metallized hazy polypropylene traction capacitors. Three ''H-Bridge'' Insulated Gate Bipolar Transistor (IGBT) switching networks are used to generate the polyphase 20 kHz transformer primary drive waveforms. The 20 kHz drive waveforms are chirped the appropriate duration to generate the desired klystron pulse width. Pulse-Width Modulation (PWM) of the individual 20 kHz pulses is utilized to provide regulated output waveforms with adaptive feedforward and feedback techniques. The boost transformer design utilizes amorphous nanocrystalline material that provides the required low core loss at design flux levels and switching frequencies. Resonant shunt peaking is used on the transformer secondary to boost output voltage and resonate transformer leakage inductance. With the appropriate transformer leakage inductance and peaking capacitance, zero-voltage-switching of the IGBT's is attained, minimizing switching losses. Reviews of these design parameters and an examination of the first operational results will be performed.

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)

Source and drain contacts are connected to opposing ends of the nanotube, or within each reservoir near the opening of the nanotube. The passage of molecular species can be sensed by measuring current flow (source-drain, ionic, or combination). The tube interior can be functionalized by joining binding molecules so that different molecular species can be sensed by detecting current changes. The nanotube may be a semiconductor, wherein a tubular transistor is formed. A gate electrode can be attached between source and drain to control current flow and ionic flow. By way of example an electrophoretic array embodiment is described, integrating MEMs switches. A variety of applications are described, such as: nanopores, nanocapillary devices, nanoelectrophoretic, DNA sequence detectors, immunosensors, thermoelectric devices, photonic devices, nanoscale fluidic bioseparators, imaging devices, and so forth.

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.

Simulating nanoscale semiconductor devices.  

SciTech Connect

The next generation of electronic devices will be developed at the nanoscale and molecular level, where quantum mechanical effects are observed. These effects must be accounted for in the design process for such small devices. One prototypical nanoscale semiconductor device under investigation is a resonant tunneling diode (RTD). Scientists are hopeful the quantum tunneling effects present in an RTD can be exploited to induce and sustain THz frequency current oscillations. To simulate the electron transport within the RTD, the Wigner-Poisson equations are used. These equations describe the time evolution of the electrons distribution within the device. In this paper, this model and a parameter study using this model will be presented. The parameter study involves calculating the steady-state current output from the RTD as a function of an applied voltage drop across the RTD and also calculating the stability of that solution. To implement the parameter study, the computational model was connected to LOCA (Library of Continuation Algorithms), a part of Sandia National Laboratories parallel solver project, Trilinos. Numerical results will be presented.

Seasonal Patterns of Melatonin, Cortisol, and Progesterone Secretion in Female Lambs Raised Beneath a 500-kV Transmission Line.  

SciTech Connect

Although several kinds of biological effects of electric and magnetic fields have been reported from laboratory studies, few have been independently replicated. When this study was being planned, the suppression of nighttime melatonin in rodents was thought to represent one of the strongest known effects of these fields. The effect had been replicated by a single laboratory for 60-Hz electric fields, and by multiple laboratories for d-c magnetic fields. The primary objective of this study was to determine whether the effect of electric and magnetic fields on melatonin would also occur in sheep exposed to a high voltage transmission line. The specific hypothesis tested by this experiment was as follows: The electrical environment produced by a 60-Hz, 500-kV transmission line causes a depression in nocturnal melatonin in chronically exposed female lambs. This may mimic effects of pinealectomy or constant long-day photoperiods, thus delaying the onset of reproductive cycles. Results of the study do not provide evidence to support the hypothesis. Melatonin concentrations in the sheep exposed to the transmission line showed the normal pattern of low daytime and high nighttime serum levels. As compared to the control group, there were no statistically significant group differences in the mean amplitude, phase, or duration of the nighttime melatonin elevation.

Note: A portable pulsed neutron source based on the smallest sealed-type plasma focus device  

Science Conference Proceedings (OSTI)

Development and operation of a portable and compact pulsed neutron source based on sealed-type plasma focus (PF) device are reported. The unit is the smallest sealed-type neutron producing PF device. The effective volume of the PF unit is 33 cm{sup 3} only. A compact size single capacitor (4 {mu}F) is used as the energy driver. A battery based power supply unit is used for charging the capacitor and triggering the spark gap. The PF unit is operated at 10 kV (200 J) and at a deuterium gas filling pressure of 8 mb. The device is operated over a time span of 200 days and the neutron emissions have been observed for 200 shots without changing the gas in between the shots. The maximum yield of this device is 7.8 x 10{sup 4} neutrons/pulse. Beyond 200 shots the yield is below the threshold (1050 neutrons/pulse) of our {sup 3}He detector.

Nuclear reactor safety device  

DOE Patents (OSTI)

A safety device is disclosed for use in a nuclear reactor for axially repositioning a control rod with respect to the reactor core in the event of an upward thermal excursion. Such safety device comprises a laminated helical ribbon configured as a tube-like helical coil having contiguous helical turns with slidably abutting edges. The helical coil is disclosed as a portion of a drive member connected axially to the control rod. The laminated ribbon is formed of outer and inner laminae. The material of the outer lamina has a greater thermal coefficient of expansion than the material of the inner lamina. In the event of an upward thermal excursion, the laminated helical coil curls inwardly to a smaller diameter. Such inward curling causes the total length of the helical coil to increase by a substantial increment, so that the control rod is axially repositioned by a corresponding amount to reduce the power output of the reactor.

DOE Patents (OSTI)

An ignition device of the plasma jet type is disclosed. The device has a cylindrical cavity formed in insulating material with an electrode at one end. The other end of the cylindrical cavity is closed by a metal plate with a small orifice in the center which plate serves as a second electrode. An arc jumping between the first electrode and the orifice plate causes the formation of a highly-ionized plasma in the cavity which is ejected through the orifice into the engine cylinder area to ignite the main fuel mixture. Two improvements are disclosed to enhance the operation of the device and the length of the plasma plume. One improvement is a metal hydride ring which is inserted in the cavity next to the first electrode. During operation, the high temperature in the cavity and the highly excited nature of the plasma breaks down the metal hydride, liberating hydrogen which acts as an additional fuel to help plasma formation. A second improvement consists of a cavity insert containing a plurality of spaced, metal rings. The rings act as secondary spark gap electrodes reducing the voltage needed to maintain the initial arc in the cavity.

Coordinating overcurrent protection devices  

Science Conference Proceedings (OSTI)

Distribution, substation, and plant engineers can benefit from using an overcurrent protection program in commercial, industrial, and utility applications to aid in clearing temporary faults and isolating permanent faults. In the time it normally takes to check one coordination scheme manually, dozens of alternatives can be evaluated using a graphics-oriented program, because the engineer receives immediate feedback for quick decision-making. It is well known that accurately coordinating overcurrent protection devices can minimize or prevent equipment damage, and electrical power service to customers can be greatly improved. In addition to assisting experienced engineers, an overcurrent protection program is an excellent training tool for new engineers.

Fluid flow monitoring device  

DOE Patents (OSTI)

This invention consists of a flow meter and temperature measuring device comprising a tube with a body centered therein for restricting flow and a sleeve at the upper end of the tube to carry several channels formed longitudinally in the sleeve to the appropriate axial location where they penetrate the tube to allow pressure measurements and temperature measurements with thermocouples. The high pressure measurement is made using a channel penetrating the tube away from the body and the low pressure measurement is made at a location at the widest part of the body. An end plug seals the end of the device and holes at its upper end allow fluid to pass from the interior of the tube into a plenum. The channels are made by cutting grooves in the sleeve, the grooves widened at the surface of the sleeve and then a strip of sleeve material is welded to the grooves closing the channels. Preferably the sleeve is packed with powdered graphite before cutting the grooves and welding the strips.

Environmental Assessment for Central Power and Light Company`s proposed Military Highway-CFE tie 138/69-kV transmission line project Brownsville, Cameron County, Texas  

SciTech Connect

Central Power and Light Company (CPL) intends to upgrade its existing transmission line ties with the Commision Federal de Electricidad (CFE) system in Mexico. CPL currently has a single 69-kilovolt (kV) transmission line in the Brownsville area which connects CPL`s system with the system of CFE. This existing line runs between the Brownsville Switching Station, located on Laredo Road in Brownsville, Cameron County, Texas, and an existing CFE 69-kV line at the Rusteberg Bend of the Rio Grande in Cameron County. Under current conditions of need, the existing 69-kV line does not possess sufficient capability to engage in appropriate power exchanges. Therefore, CPL is proposing to build a new line to link up with CFE. This proposed line would be a double-circuit line, which would (1) continue (on a slightly relocated route) the existing 69-kV tie from CPL`s Brownsville Switching Station to CFE`s facilities, and (2) add a 138-kV tie from the Military Highway Substation, located on Military Highway (US Highway 281), to CFE`s facilities. The proposed 138/69-kV line, which will be constructed and operated by CPL, will be built primarily on steel single-pole structures within an average 60-foot (ft) wide right-of-way (ROW). It will be approximately 6900--9200 ft (1.3--1.7 miles) in length, depending on the alternative route constructed.

DOE Patents (OSTI)

A safety device is described for use in a nuclear reactor for axially repositioning a control rod with respect to the reactor core in the event of a thermal excursion. It comprises a laminated strip helically configured to form a tube, said tube being in operative relation to said control rod. The laminated strip is formed of at least two materials having different thermal coefficients of expansion, and is helically configured such that the material forming the outer lamina of the tube has a greater thermal coefficient of expansion than the material forming the inner lamina of said tube. In the event of a thermal excursion the laminated strip will tend to curl inwardly so that said tube will increase in length, whereby as said tube increases in length it exerts a force on said control rod to axially reposition said control rod with respect to said core.

Programmable logic devices  

Science Conference Proceedings (OSTI)

Erasable programmable logic devices (EPLDs) were investigated to determine their advantages and/or disadvantages in Test Equipment Engineering applications. It was found that EPLDs performed as well as or better than identical circuits using standard TTL logic. The chip count in these circuits was reduced, saving printed circuit board space and shortening fabrication and prove-in time. Troubleshooting circuits of EPLDs was also easier with 10 to 100 times fewer wires needed. The reduced number of integrated circuits (ICs) contributed to faster system speeds and an overall lower power consumption. In some cases changes to the circuit became software changes using EPLDs instead of hardware changes for standard logic. Using EPLDs was fairly easy; however, as with any new technology, a learning curve must be overcome before EPLDs can be used efficiently. The many benefits of EPLDs outweighed this initial inconvenience.

Tool setting device  

DOE Patents (OSTI)

The present invention relates to a tool setting device for use with numerically controlled machine tools, such as lathes and milling machines. A reference position of the machine tool relative to the workpiece along both the X and Y axes is utilized by the control circuit for driving the tool through its program. This reference position is determined for both axes by displacing a single linear variable displacement transducer (LVDT) with the machine tool through a T-shaped pivotal bar. The use of the T-shaped bar allows the cutting tool to be moved sequentially in the X or Y direction for indicating the actual position of the machine tool relative to the predetermined desired position in the numerical control circuit by using a single LVDT.

Capacitance measuring device  

DOE Patents (OSTI)

A capacitance measuring circuit is provided in which an unknown capacitance is measured by comparing the charge stored in the unknown capacitor with that stored in a known capacitance. Equal and opposite voltages are repetitively simultaneously switched onto the capacitors through an electronic switch driven by a pulse generator to charge the capacitors during the ''on'' portion of the cycle. The stored charge is compared by summing discharge currents flowing through matched resistors at the input of a current sensor during the ''off'' portion of the switching cycle. The net current measured is thus proportional to the difference in value of the two capacitances. The circuit is capable of providing much needed accuracy and stability to a great variety of capacitance-based measurement devices at a relatively low cost.

Ceramics for fusion devices  

SciTech Connect

Ceramics are required for a number of applications in fusion devices, among the most critical of which are magnetic coil insulators, windows for RF heating systems, and structural uses. Radiation effects dominate consideration of candidate materials, although good pre-irradiation properties are a requisite. Materials and components can be optimized by careful control of chemical and microstructural content, and application of brittle material design and testing techniques. Future directions for research and development should include further extension of the data base in the areas of electrical, structural, and thermal properties; establishment of a fission neutron/fusion neutron correlation including transmutation gas effects; and development of new materials tailored to meet the specific needs of fusion reactors.

Measuring time of flight of fusion products in an inertial electrostatic confinement fusion device for spatial profiling of fusion reactions  

Science Conference Proceedings (OSTI)

A new diagnostic has been developed that uses the time of flight (TOF) of the products from a nuclear fusion reaction to determine the location where the fusion reaction occurred. The TOF diagnostic uses charged particle detectors on opposing sides of the inertial electrostatic confinement (IEC) device that are coupled to high resolution timing electronics to measure the spatial profile of fusion reactions occurring between the two charged particle detectors. This diagnostic was constructed and tested by the University of Wisconsin-Madison Inertial Electrostatic Confinement Fusion Group in the IEC device, HOMER, which accelerates deuterium ions to fusion relevant energies in a high voltage ({approx}100 kV), spherically symmetric, electrostatic potential well [J. F. Santarius, G. L. Kulcinski, R. P. Ashley, D. R. Boris, B. B. Cipiti, S. K. Murali, G. R. Piefer, R. F. Radel, T. E. Radel, and A. L. Wehmeyer, Fusion Sci. Technol. 47, 1238 (2005)]. The TOF diagnostic detects the products of D(d,p)T reactions and determines where along a chord through the device the fusion event occurred. The diagnostic is also capable of using charged particle spectroscopy to determine the Doppler shift imparted to the fusion products by the center of mass energy of the fusion reactants. The TOF diagnostic is thus able to collect spatial profiles of the fusion reaction density along a chord through the device, coupled with the center of mass energy of the reactions occurring at each location. This provides levels of diagnostic detail never before achieved on an IEC device.

New Switches for Utility-Scale Inverters: First In-Class Demonstration of a Completely New Type of SiC Bipolar Switch (15kV-20kV) for Utility-Scale Inverters  

Science Conference Proceedings (OSTI)

Solar ADEPT Project: The SiCLAB is developing a new power switch for utility-scale PV inverters that would improve the performance and significantly reduce the size, weight, and energy loss of PV systems. A power switch controls the electrical energy flowing through an inverter, which takes the electrical current from a PV solar panel and converts it into the type and amount of electricity that is compatible with the electric grid. SiCLAB is using silicon carbide (SiC) semiconductors in its new power switches, which are more efficient than the silicon semiconductors used to conduct electricity in most conventional power switches today. Switches with SiC semiconductors can operate at much higher temperatures, as well as higher voltage and power levels than silicon switches. SiC-based power switches are also smaller than those made with silicon alone, so they result in much smaller and lighter electrical devices. In addition to their use in utility-scale PV inverters, SiCLABs new power switches can also be used in wind turbines, railways, and other smart grid applications.

Radiation-tolerant imaging device  

DOE Patents (OSTI)

A barrier at a uniform depth for an entire wafer is used to produce imaging devices less susceptible to noise pulses produced by the passage of ionizing radiation. The barrier prevents charge created in the bulk silicon of a CCD detector or a semiconductor logic or memory device from entering the collection volume of each pixel in the imaging device. The charge barrier is a physical barrier, a potential barrier, or a combination of both. The physical barrier is formed by an SiO.sub.2 insulator. The potential barrier is formed by increasing the concentration of majority carriers (holes) to combine with the electron's generated by the ionizing radiation. A manufacturer of CCD imaging devices can produce radiation-tolerant devices by merely changing the wafer type fed into his process stream from a standard wafer to one possessing a barrier beneath its surface, thus introducing a very small added cost to his production cost. An effective barrier type is an SiO.sub.2 layer.

Dual control active superconductive devices  

DOE Patents (OSTI)

A superconducting active device has dual control inputs and is constructed such that the output of the device is effectively a linear mix of the two input signals. The device is formed of a film of superconducting material on a substrate and has two main conduction channels, each of which includes a weak link region. A first control line extends adjacent to the weak link region in the first channel and a second control line extends adjacent to the weak link region in the second channel. The current flowing from the first channel flows through an internal control line which is also adjacent to the weak link region of the second channel. The weak link regions comprise small links of superconductor, separated by voids, through which the current flows in each channel. Current passed through the control lines causes magnetic flux vortices which propagate across the weak link regions and control the resistance of these regions. The output of the device taken across the input to the main channels and the output of the second main channel and the internal control line will constitute essentially a linear mix of the two input signals imposed on the two control lines. The device is especially suited to microwave applications since it has very low input capacitance, and is well suited to being formed of high temperature superconducting materials since all of the structures may be formed coplanar with one another on a substrate.

Survey of hydrogen monitoring devices  

DOE Green Energy (OSTI)

Presented are results of a survey of commercially available monitoring devices suitable for hydrogen detection in the secondary containment vessel of a nuclear power plant during the post postulated accident period. Available detectors were grouped into the following five classes: combustion, solid state, electrochemical, thermal conductivity, and absorption. The performance of most available sensors is likely to deteriorate when exposed to the postulated conditions which include moisture, which could be at high temperature, and radioactive noncondensibles. Of the commercial devices, those using metallic filament thermal conductivity detectors seem least susceptible to performance change. Absorption detectors are best suited for this monitoring task but the only available device is designed for pipeline corrosion assessment. Initiation of experimental study to assess apparent deficiencies of commercial detectors is recommended. Also recommended is an analytical/experimental effort to determine the optimum detector array for monitoring in the secondary containment vessels.

Spectral utilization in thermophotovoltaic devices  

DOE Green Energy (OSTI)

Multilayer assemblies of epitaxially-grown, III-V semiconductor materials are being investigated for use in thermophotovoltaic (TPV) energy conversion applications. It has been observed that thick, highly-doped semiconductor layers within cell architectures dominate the parasitic free-carrier absorption (FCA) of devices at wavelengths above the bandgap of the semiconductor material. In this work, the wavelength-dependent, free-carrier absorption of p- and n-type InGaAs layers grown epitaxially onto semi-insulating (SI) InP substrates has been measured and related to the total absorption of long-wavelength photons in thermophotovoltaic devices. The optical responses of the TPV cells are then used in the calculation of spectral utilization factors and device efficiencies.

Activation measurements of high energy deuterons in the plasma focus device  

SciTech Connect

Nuclear activation techniques were used to measure the fluence of high energy deuterons in a plasma focus device having a stored energy of 75 kilojoules at 18 kV. The $sup 12$C(d,n)$sup 13$N (330 keV threshold) and $sup 27$Al(d,p)$sup 28$Al reactions were used to provide both an absolute number of high energy deuterons and an average energy, evaluated from the $sup 13$N/$sup 28$Al ratio calculated for various energies by Young. Previous measurements indicated more than 10$sup 15$ deuterons could be accelerated to energies above 330 keV in the low pressure mode of operation, with a highly anisotropic distribution. Present measurements show that more than 10$sup 12$ deuterons achieve energies greater than 5 MeV on some high intensity shots in the low pressure mode. The presence of multi-MeV deuterons in the plasma focus device was substantiated by measuring activation as a function of depth in 1 mil Al foils, and by measurements of neutron energy using time-of-flight.

Proposed amendment for Presidential Permit PP-63 and associated modifications to 500 kV international transmission line, Forbes, Minnesota to Manitoba, Canada Northern States Power Company. Final Environmental Assessment  

SciTech Connect

Northern States Power Company, (NSP), a Minnesota investor owned utility has applied to the Office of Fossil Energy, United States Department of Energy, to amend Presidential Permit PP-63 to allow for alterations to the 500 kV transmission line and as sedated facilities currently regulated by this permit. The alterations proposed for the 500 kV line owned by NSP are part of a long term effort sponsored by NSP to upgrade the existing NSP transmission system to allow for increased exchange of electricity with the Manitoba Hydro-Electric Board. Presidential Permit PP-63 authorized NSP to construct, connect, operate and maintain a 500 kV line at the United States/Canadian border approximately seven-and-a-half miles west of Warroad in Roseau County, Minnesota. This line connects with a 500 kV line owned and operated by the Manitoba Hydro-Electric Board (MHEB), which extends from Dorsey, Manitoba, Canada to the United States/Canadian border. NSP proposes to increase the electricity transfer capability of this transmission facility by constructing a new 80-acre substation on the existing 500 kV line in Roseau County, Minnesota, and upgrading the existing substation at Forbes, Minnesota. The proposed Roseau substation would contain two 41.5 ohm series capacitor banks. In addition, static VAR compensators are to be installed at the existing Forbes Substation. Approximately 5 acres would be added to the 30-acre Forbes site to house the additional equipment. No new lines would enter or exit the facility. NSP proposes to place the new Roseau Substation in service in May 1993 and to complete the upgrading of the Forbes Substation in March 1994. The primary, initial purpose of these modifications is to enable NSP to import 400 megawatts of electric power from MHEB during the summer months to meet peak electrical demand in the Minneapolis-St. Paul area. It is expected that this power transfer would begin in 1993.

The device includes an inner split ring member connected on one end to a middle ring member wherein the free end of the split ring member is inserted through a slit in the plastic sheeting to captively engage a generally circular portion of the plastic sheeting. A collar portion having an outer ring portion is provided with fastening means for securing the device together wherein the glovebag is operatively connected to the collar portion. Hazardous material such as radioactive waste may be sealed in plastic bags for small items or wrapped in plastic sheeting for large items. Occasionally the need arises to access the hazardous material in a controlled manner, that is, while maintaining total containment. Small items could be placed entirely inside a containment glovebag. However, it may not be possible or practical to place large items inside a containment; instead, one or more glovebags could be attached to the plastic sheeting covering the hazardous material. It is this latter application for which the split ring containment attachment device is intended.

ICRF heating on helical devices  

SciTech Connect

Ion cyclotron range of frequency (ICRF) heating is currently in use on CHS and W7AS and is a major element of the heating planned for steady state helical devices. In helical devices, the lack of a toroidal current eliminates both disruptions and the need for ICRF current drive, simplifying the design of antenna structures as compared to tokamak applications. However the survivability of plasma facing components and steady state cooling issues are directly applicable to tokamak devices. Results from LHD steady state experiments should be available on a time scale to strongly influence the next generation of steady state tokamak experiments. The helical plasma geometry provides challenges not faced with tokamak ICRF heating, including the potential for enhanced fast ion losses, impurity accumulation, limited access for antenna structures, and open magnetic field lines in the plasma edge. The present results and near term plans provide the basis for steady state ICRF heating of larger helical devices. An approach which includes direct electron, mode conversion, ion minority and ion Bernstein wave heating addresses these issues.

Editorial: Photovoltaic Materials and Devices  

Science Conference Proceedings (OSTI)

As the global energy needs grow, there is increasing interest in the generation of electricity by photovoltaics (PVs) devices or solar cells - devices that convert sunlight to electricity. Solar industry has seen an enormous growth during the last decade. The sale of PV modules has exceeded 27 GW in 2011, with significant contributions to the market share from all technologies. While the silicon technology continues to have the dominant share, the other thin film technologies (CdTe, CIGS, a-Si, and organic PV) are experiencing fast growth. Increased production of silicon modules has led to a very rapid reduction in their price and remains as benchmark for other technologies. The PV industry is in full gear to commercialize new automated equipment for solar cell and module production, instrumentation for process monitoring technologies, and for implementation of other cost-reduction approaches, and extensive research continues to be carried out in many laboratories to improve the efficiency of solar cells and modules without increasing the production costs. A large variety of solar cells, which differ in the material systems used, design, PV structure, and even the principle of PV conversion, are designed to date. This special issue contains peer-reviewed papers in the recent developments in research related to broad spectrum of photovoltaic materials and devices. It contains papers on many aspects of solar cells-the growth and deposition, characterization, and new material development.

Sketch Recognition on Mobile Devices  

E-Print Network (OSTI)

Sketch recognition allows computers to understand and model hand drawn sketches and diagrams. Traditionally sketch recognition systems required a pen based PC interface, but powerful mobile devices such as tablets and smartphones can provide a new platform for sketch recognition systems. We describe a new sketch recognition library, Strontium (SrL) that combines several existing sketch recognition libraries modified to run on both personal computers and on the Android platform. We analyzed the recognition speed and accuracy implications of performing low-level shape recognition on smartphones with touch screens. We found that there is a large gap in recognition speed on mobile devices between recognizing simple shapes and more complex ones, suggesting that mobile sketch interface designers limit the complexity of their sketch domains. We also found that a low sampling rate on mobile devices can affect recognition accuracy of complex and curved shapes. Despite this, we found no evidence to suggest that using a finger as an input implement leads to a decrease in simple shape recognition accuracy. These results show that the same geometric shape recognizers developed for pen applications can be used in mobile applications, provided that developers keep shape domains simple and ensure that input sampling rate is kept as high as possible.

Passive fault current limiting device  

DOE Patents (OSTI)

A passive current limiting device and isolator is particularly adapted for use at high power levels for limiting excessive currents in a circuit in a fault condition such as an electrical short. The current limiting device comprises a magnetic core wound with two magnetically opposed, parallel connected coils of copper, a high temperature superconductor or other electrically conducting material, and a fault element connected in series with one of the coils. Under normal operating conditions, the magnetic flux density produced by the two coils cancel each other. Under a fault condition, the fault element is triggered to cause an imbalance in the magnetic flux density between the two coils which results in an increase in the impedance in the coils. While the fault element may be a separate current limiter, switch, fuse, bimetal strip or the like, it preferably is a superconductor current limiter conducting one-half of the current load compared to the same limiter wired to carry the total current of the circuit. The major voltage during a fault condition is in the coils wound on the common core in a preferred embodiment. 6 figs.

Device for absorbing mechanical shock  

DOE Patents (OSTI)

This invention is a comparatively inexpensive but efficient shock-absorbing device having special application to the protection of shipping and storage cylinders. In a typical application, two of the devices are strapped to a cylinder to serve as saddle-type supports for the cylinder during storage and to protect the cylinder in the event it is dropped during lifting or lowering operations. In its preferred form, the invention includes a hardwood plank whose grain runs in the longitudinal direction. The basal portion of the plank is of solid cross-section, whereas the upper face of the plank is cut away to form a concave surface fittable against the sidewall of a storage cylinder. The concave surface is divided into a series of segments by transversely extending, throughgoing relief slots. A layer of elastomeric material is positioned on the concave face, the elastomer being extrudable into slots when pressed against the segments by a preselected pressure characteristic of a high-energy impact. The compressive, tensile, and shear properties of the hardwood and the elastomer are utilized in combination to provide a surprisingly high energy-absorption capability.

Programmable logic devices. Final report  

SciTech Connect

Erasable programmable logic devices (EPLDs) were investigated to determine their advantages and/or disadvantages in Test Equipment Engineering applications. It was found that EPLDs performed as well as or better than identical circuits using standard TTL logic. The chip count in these circuits was reduced, saving printed circuit board space and shortening fabrication and prove-in time. Troubleshooting circuits of EPLDs was also easier with 10 to 100 times fewer wires needed. The reduced number of integrated circuits (ICs) contributed to faster system speeds and an overall lower power consumption. In some cases changes to the circuit became software changes using EPLDs instead of hardware changes for standard logic. Using EPLDs was fairly easy; however, as with any new technology, a learning curve must be overcome before EPLDs can be used efficiently. The many benefits of EPLDs outweighed this initial inconvenience.

Seal device for ferromagnetic containers  

DOE Patents (OSTI)

A temporary seal or patch assembly prevents the escape of contents, e.g., fluids and the like, from within a container having a breach therethrough until the contents can be removed and/or a repair effected. A frame that supports a sealing bladder can be positioned over the breach and the frame is then attached to the container surface, which must be of a ferromagnet material, by using switchable permanent magnets. The permanent magnets are designed to have a first condition that is not attracted to the ferromagnetic surface and a second conditions whereby the magnets are attracted to the surface with sufficient force to support the seal assembly on the surface. Latching devices may be attached to the frame and engage the container surface with hardened pins to prevent the lateral movement of the seal assembly along the container surface from external forces such as fluid drag or gravity.

Assembly of the PLT device  

SciTech Connect

The assembly of the PLT device began in June 1974 with a preassembly of the mechanical structure at a remote site. The preassembly sequence incorporated final fabrication procedures with an initial staging operation. This successful staging/fabrication procedure proved to be an invaluable asset when the final assembly was started in August 1974. The assembly continued with the initial reassembly of the previously tested structural components at the final machine site. Construction was interrupted at several points to allow for toroidal field coil, vacuum vessel, and poloidal coil installation. Two phases of toroidal field coil power tests were included in the assembly sequence prior to, and just after the vacuum vessel insertion. (auth)

Antimonide based devices for thermophotovoltaic applications  

DOE Green Energy (OSTI)

Thermophotovoltaic (TPV) devices have been fabricated using epitaxial ternary and quaternary layers grown on GaSb substrates. GaInSb ternary devices were grown by metalorganic vapor phase epitaxy (MOVPE) with buffer layers to accommodate the lattice mismatch, and GaInAsSb lattice-matched quaternaries were grown by MOVPE. Improved devices are obtained when optical absorption occurs in the p-layer due to the longer minority carrier diffusion length. Thick emitter p/n devices are limited by surface recombination, with highest quantum efficiency and lowest dark current being achieved with epitaxially grown surface passivation layers on lattice-matched MOVPE quaternaries. Thin emitter/thick base, n/p devices are very promising, but require improved shallow high-quality n-type ohmic contacts. Diffused junction devices using quasi-binary substrates offer the possibility of good performance and low manufacturing cost.

The On-Device Dynamic Analysis of Mobile Applications (ODAMA) project was started in an effort to protect mobile devices used in Industrial Control Systems (ICS) from cyber attack. Because mobile devices hide as much of the computer as possible, the users ability to assess the software running on their system is limited. The research team chose Googles Android platform for this initial research because it is open source and it would give us freedom in our approach, including the ability to modify the mobile devices operating system itself. The research team concluded that a Privileged Application was the right approach, and the result was ODAMA. This project is an important piece of the work to secure the expanding use of mobile devices with our nations critical infrastructure.

Passive gas separator and accumulator device  

DOE Patents (OSTI)

A separation device employing a gas separation filter and swirler vanes for separating gas from a gas-liquid mixture is provided. The cylindrical filter utilizes the principle that surface tension in the pores of the filter prevents gas bubbles from passing through. As a result, the gas collects in the interior region of the filter and coalesces to form larger bubbles in the center of the device. The device is particularly suited for use in microgravity conditions since the swirlers induce a centrifugal force which causes liquid to move from the inner region of the filter, pass the pores, and flow through the outlet of the device while the entrained gas is trapped by the filter. The device includes a cylindrical gas storage screen which is enclosed by the cylindrical gas separation filter. The screen has pores that are larger than those of the filters. The screen prevents larger bubbles that have been formed from reaching and interfering with the pores of the gas separation filter. The device is initially filled with a gas other than that which is to be separated. This technique results in separation of the gas even before gas bubbles are present in the mixture. Initially filling the device with the dissimilar gas and preventing the gas from escaping before operation can be accomplished by sealing the dissimilar gas in the inner region of the separation device with a ruptured disc which can be ruptured when the device is activated for use. 3 figs.

Delp, Michael G. Apte, and Phillip N. Price Journal Indoor Air Volume 22 Issue 3 Pagination 224-234 Date Published 06/2012 Keywords carbon monoxide, natural gas burners, nitrogen dioxide, range hood, task ventilation, unvented combustion, indoor environment group, Range Hood Test Facility Abstract The performance metrics of airflow, sound, and combustion product capture efficiency (CE) were measured for a convenience sample of fifteen cooking exhaust devices, as installed in residences. Results were analyzed to quantify the impact of various device- and installation-dependent parameters on CE. Measured maximum airflows were 70% or lower than values noted on product literature for 10 of the devices. Above-the-cooktop devices with flat bottom surfaces (no capture hood) - including exhaust fan/microwave combination appliances - were found to have much lower CE at similar flow rates, compared to devices with capture hoods. For almost all exhaust devices and especially for rear-mounted downdraft exhaust and microwaves, CE was substantially higher for back compared with front burner use. Flow rate, and the extent to which the exhaust device extends over the burners that are in use, also had a large effect on CE. A flow rate of 95 liters per second (200 cubic feet per minute) was necessary, but not sufficient, to attain capture efficiency in excess of 75% for the front burners. A-weighted sound levels in kitchens exceeded 57 dB when operating at the highest fan setting for all 14 devices evaluated for sound performance.

Passive gas separator and accumulator device  

DOE Patents (OSTI)

A separation device employing a gas separation filter and swirler vanes for separating gas from a gas-liquid mixture is provided. The cylindrical filter uses the principle that surface tension in the filter pores prevents gas bubbles from passing through; the gas collects in the interior of the filter to form larger bubbles in the center of the device. The device is suited for microgravity since the swirlers induce a centrifugal force which forces liquid from the inner region through the pores and the device outlet while the entrained gas is trapped by the filter. The device includes a cylindrical gas storage screen enclosed by the filter. The screen has pores larger than those of the filters. The screen prevents larger bubbles that have been formed from reaching and interfering with the pores of the filter. The device is initially filled with a gas other than that which is to be separated; this results in separation of the gas even before gas bubbles are present in the mixture. Initially filling the device with the dissimilar gas and preventing the gas from escaping before operation can be accomplished by sealing the dissimilar gas in the inner region with a ruptured disc which can be ruptured when the device is activated for use.

Performance of Installed Cooking Exhaust Devices  

Science Conference Proceedings (OSTI)

The performance metrics of airflow, sound, and combustion product capture efficiency (CE) were measured for a convenience sample of fifteen cooking exhaust devices, as installed in residences. Results were analyzed to quantify the impact of various device- and installation-dependent parameters on CE. Measured maximum airflows were 70% or lower than values noted on product literature for 10 of the devices. Above-the-cooktop devices with flat bottom surfaces (no capture hood) including exhaust fan/microwave combination appliances were found to have much lower CE at similar flow rates, compared to devices with capture hoods. For almost all exhaust devices and especially for rear-mounted downdraft exhaust and microwaves, CE was substantially higher for back compared with front burner use. Flow rate, and the extent to which the exhaust device extends over the burners that are in use, also had a large effect on CE. A flow rate of 95 liters per second (200 cubic feet per minute) was necessary, but not sufficient, to attain capture efficiency in excess of 75% for the front burners. A-weighted sound levels in kitchens exceeded 57 dB when operating at the highest fan setting for all 14 devices evaluated for sound performance.

Quantum communication devices, such as quantum repeaters, quantum memories, or quantum channels, are unavoidably exposed to imperfections. However, the presence of imperfections can be tolerated, as long as we can verify such devices retain their quantum advantages. Benchmarks based on witnessing entanglement have proven useful for verifying the true quantum nature of these devices. The next challenge is to characterize how strongly a device is within the quantum domain. We present a method, based on entanglement measures and rigorous state truncation, which allows us to characterize the degree of quantumness of optical devices. This method serves as a quantitative extension to a large class of previously-known quantum benchmarks, requiring no additional information beyond what is already used for the non-quantitative benchmarks.

Light collection device for flame emission detectors  

DOE Patents (OSTI)

This report describes a light collection device for use in a flame emission detection system such as an on-line, real-time alkali concentration process stream monitor. The device comprises a sphere coated on its interior with a highly diffuse reflective paint which is positioned over a flame emission source and one or more fiber optic cables which transfer the light generated at the interior of the sphere to a detecting device. The diffuse scattering of the light emitted by the flame uniformly distributes the light in the sphere, and the collection efficiency of the device is greater than that obtainable in the prior art. The device of the present invention thus provides enhanced sensitivity and reduces the noise associated with flame emission detectors, and can achieve substantial improvements in alkali detection levels. 2 figs.

The peripheral seal bodies are made of resilient material having a generally U-shaped cross section wherein one of the legs is secured to a support member and the other of the legs forms a contacting seal against the rotary device. The legs of the peripheral seal form an extended angle of intersection of about 10.degree. to about 30.degree. in the unloaded condition to provide even sealing forces around the periphery of the rotary device. The peripheral seal extends around the periphery of the support member except where intersected by radial seals which reduce gas leakage across the face of the rotary device and between adjacent duct portions. The radial seal assembly is fabricated from channel bars, the smaller channel bar being secured to the divider of the support member and a larger inverted rigid floating channel bar having its legs freely movable over the legs of the smaller channel bar forming therewith a tubular channel. A resilient flexible tube is positioned within the tubular channel for substantially its full length to reduce gas leakage across the tubular channel. A spacer extends beyond the face of the floating channel near each end of the floating channel a distance to provide desired clearance between the floating channel and the face of the rotary device.

Environmental Assessment and Finding of No Significant Impact: Western's Hoover Dam Bypass Project Phase II (Double-Circuiting a Portion of the Hoover-Mead No.5 and No.7 230-kV Transmission Lines with the Henderson-Mead No.1 230-kV Transmission Line, Clark County, Nevada)  

SciTech Connect

The U.S. Highway 93 (U.S. 93) Hoover Dam Bypass Project calls for the U.S. Department of Energy (DOE) Western Area Power Administration (Western) to remove its Arizona and Nevada (A&N) Switchyard. As a result of this action, Western must reconfigure its existing electrical transmission system in the Hoover Dam area. Western proposes to double-circuit a portion of the Hoover-Mead No.5 and No.7 230-kV Transmission Lines with the Henderson-Mead No.1 Transmission Line (see Figure 1-1). Double-circuiting is the placement of two separate electrical circuits, typically in the form of three separate conductors or bundles of conductors, on the same set of transmission line structures. The old Henderson-Hoover 230-kV Transmission Line would become the new Henderson-Mead No.1 and would extend approximately eight miles to connect with the Mead Substation. Western owns, operates, and maintains the Hoover-Mead No.5 and No.7, and Henderson-Hoover electrical power transmission lines. Additionally, approximately 0.25 miles of new right-of-way (ROW) would be needed for the Henderson-Mead No.1 when it transfers from double-circuiting with the Hoover-Mead No.7 to the Hoover-Mead No.5 at the Boulder City Tap. The proposed project would also involve a new transmission line ROW and structures where the Henderson-Mead No.1 will split from the Hoover-Mead No.5 and enter the northeast corner of the Mead Substation. Lastly, Western has proposed adding fiber optic overhead ground wire from the Hoover Power Plant to the Mead Substation on to the Henderson-Mead No.1, Hoover-Mead No.5 and No.7 Transmission Lines. The proposed project includes replacing existing transmission line tower structures, installing new structures, and adding new electrical conductors and fiber optic cables. As a consequence of these activities, ground disturbance may result from grading areas for structure placement, constructing new roads, improving existing roads for vehicle and equipment access, and from installing structures, conductors, and fiber optic cables. Project construction activities would be conducted within the existing 200-foot transmission line ROW and 50-foot access road ROW, although new spur access roads could occur outside of existing ROWs. As lead Federal agency for this action under National Environmental Policy Act (NEPA), Western must ensure that adverse environmental effects on Federal and non-Federal lands and resources are avoided or minimized. This Environmental Assessment (EA) is intended to be a concise public document that assesses the probable and known impacts to the environment from Western's Proposed Action and alternatives, and reaches a conclusion about the significance of the impacts. This EA was prepared in compliance with NEPA regulations published by the Council on Environmental Quality (40 CFR 1500-1508) and implementing procedures of the Department of Energy (10 CFR 1021).

DOE Patents (OSTI)

An insertion device for extracting polarized electromagnetic energy from a beam of particles is disclosed. The insertion device includes four linear arrays of magnets which are aligned with the particle beam. The magnetic field strength to which the particles are subjected is adjusted by altering the relative alignment of the arrays in a direction parallel to that of the particle beam. Both the energy and polarization of the extracted energy may be varied by moving the relevant arrays parallel to the beam direction. The present invention requires a substantially simpler and more economical superstructure than insertion devices in which the magnetic field strength is altered by changing the gap between arrays of magnets.

SciTech Connect

Proposed is the construction of a 15-mile, 230-kV double-circuit transmission line from Franklin Substation near Pasco, Washington, to a proposed new Badger Canyon Substation to be constructed 5 miles west of Kennewick, Washington. 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.

Bulk Heterojunction Organic Photovoltaic Devices Using Dendrimers  

Science Conference Proceedings (OSTI)

A family of prototype ..pi..-conjugated dendrimers has been synthesized and incorporated into solution-processable organic photovoltaic (OPV) devices. Bulk heterojunction devices were fabricated by blending the dendrimers with a solubilized fullerene. The best of these initial devices, which were not optimized for morphology, exhibited external quantum efficiencies of 22% at peak wavelength. It was found that 3-arm dendrimers, when sufficiently soluble, yielded higher photocurrents than their 4-arm counterparts. This was attributed to better planarity and intermolecular alignment of the 3-arm version. Device efficiency was seen to increase with increasing arm length. A reduced-band gap dendrimer was synthesized by attaching electron-withdrawing groups onto the core to yield an optical band gap of 1.82 eV.

Light collection device for flame emission detectors  

DOE Patents (OSTI)

A light collection device for use in a flame emission detection system such as an on-line, real-time alkali concentration process stream monitor is disclosed which comprises a sphere coated on its interior with a highly diffuse reflective paint which is positioned over a flame emission source, and one or more fiber optic cables which transfer the light generated at the interior of the sphere to a detecting device. The diffuse scattering of the light emitted by the flame uniformly distributes the light in the sphere, and the collection efficiency of the device is greater than that obtainable in the prior art. The device of the present invention thus provides enhanced sensitivity and reduces the noise associated with flame emission detectors, and can achieve substantial improvements in alkali detection levels.

Microelectronic device package with an integral window  

DOE Patents (OSTI)

An apparatus for packaging of microelectronic devices, including an integral window. The microelectronic device can be a semiconductor chip, a CCD chip, a CMOS chip, a VCSEL chip, a laser diode, a MEMS device, or a IMEMS device. The package can include a cofired ceramic frame or body. The package can have an internal stepped structure made of one or more plates, with apertures, which are patterned with metallized conductive circuit traces. The microelectronic device can be flip-chip bonded on the plate to these traces, and oriented so that the light-sensitive side is optically accessible through the window. A cover lid can be attached to the opposite side of the package. The result is a compact, low-profile package, having an integral window that can be hermetically-sealed. The package body can be formed by low-temperature cofired ceramic (LTCC) or high-temperature cofired ceramic (HTCC) multilayer processes with the window being simultaneously joined (e.g. cofired) to the package body during LTCC or HTCC processing. Multiple chips can be located within a single package. The cover lid can include a window. The apparatus is particularly suited for packaging of MEMS devices, since the number of handling steps is greatly reduced, thereby reducing the potential for contamination.

Laser focus compensating sensing and imaging device  

DOE Patents (OSTI)

A laser focus compensating sensing and imaging device permits the focus of a single focal point of different frequency laser beams emanating from the same source point. In particular it allows the focusing of laser beams originating from the same laser device but having differing intensities so that a low intensity beam will not convert to a higher frequency when passing through a conversion crystal associated with the laser generating device. The laser focus compensating sensing and imaging device uses a cassegrain system to fold the lower frequency, low intensity beam back upon itself so that it will focus at the same focal point as a high intensity beam. An angular tilt compensating lens is mounted about the secondary mirror of the cassegrain system to assist in alignment. In addition cameras or CCD`s are mounted with the primary mirror to sense the focused image. A convex lens in positioned coaxial with the cassegrain system on the side of the primary mirror distal of the secondary for use in aligning a target with the laser beam. A first alternate embodiment includes a cassegrain system using a series of shuttles and an internally mounted dichroic mirror. A second alternate embodiment uses two laser focus compensating sensing and imaging devices for aligning a moving tool with a work piece.

A Nuclear Microbattery for MEMS Devices  

DOE Green Energy (OSTI)

This project was designed to demonstrate the feasibility of producing on-board power for MEMS devices using radioisotopes. MEMS is a fast growing field, with hopes for producing a wide variety of revolutionary applications, including ''labs on a chip,'' micromachined scanning tunneling microscopes, microscopic detectors for biological agents, microsystems for DNA identification, etc. Currently, these applications are limited by the lack of an on-board power source. Research is ongoing to study approaches such as fuel cells, fossil fuels, and chemical batteries, but all these concepts have limitations. For long-lived, high energy density applications, on-board radioisotope power offers the best choice. We have succeeded in producing such devices using a variety of isotopes, incorporation methods, and device geometries. These experiments have demonstrated the feasibility of using radioisotope power and that there are a variety of options available for MEMS designers. As an example of an integrated, self-powered application, we have created an oscillating cantilever beam that is capable of consistent, periodic oscillations over very long time periods without the need for refueling. Ongoing work will demonstrate that this cantilever is capable of radio frequency transmission, allowing MEMS devices to communicate with one another wirelessly. Thus, this will be the first self-powered wireless transmitter available for use in MEMS devices, permitting such applications as sensors embedded in buildings for continuous monitoring of the building performance and integrity.
