Substation voltage upgrading  

SciTech Connect (OSTI)

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

Substation fire protection features  

SciTech Connect (OSTI)

This paper describes Commonwealth Edison`s (ComEd) approach to substation fire protection. Substation fires can have a major operational, financial, as well as political impact on a utility. The overall Company philosophy encompasses both active and passive fire protection features to provide prompt detection, notification, and confinement of fire and its by-products. Conservatively designed smoke detection systems and floor and wall penetration seals form the backbone of this strategy. The Company has implemented a program to install these features in new and existing substations. Thus far these measures have been successful in mitigating the consequences of substation fires.

Substation voltage upgrading  

SciTech Connect (OSTI)

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

Inter substation data communications  

SciTech Connect (OSTI)

The paper briefly describes the scada system operated by ComEd for substation communications. This system has proven a reliable means for monitor and control of the generation, transmission, and distribution system. An attempt to automate stand-alone substation functions into the RTU has had limited success. An automated substation capacitor control algorithm was incorporated into a PC. The PC directly interfaced with the RTU through the serial port for analog monitoring and control of the capacitor banks. There were no further enhancements or development of other control algorithms with the PC. The paper discusses the power system data evolution, the proposed design improvements, and implementation concerns.

Substation grounding programs  

SciTech Connect (OSTI)

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

Chapter 3 - Substation Layouts  

Science Journals Connector (OSTI)

Publisher Summary Substations are the points in the power network, where transmission lines and distribution feeders are connected together through circuit breakers or switches via busbars and transformers. This allows for the control of power flows in the network and general switching operations for maintenance purposes. This chapter describes the principal substation layouts, the effects of advancements in substation equipment, the modular design, the compact substations, and the moves toward design and construction “turnkey” contract work. The descriptions concentrate on air insulated switchgear (AIS) outdoor open terminal designs at rated voltages of 72 kV and higher. In an ideal situation all circuits and substation equipment would be duplicated such that following a fault or during maintenance a connection remains available. This would involve very high cost. Methods have therefore been adopted to achieve a compromise between complete security of supply and capital investment. A measure of circuit duplication is adopted while recognizing that duplication may itself reduce the security of supply by, for example, providing additional leakage paths to earth.

The fourth program, TGRND, is an analysis program for determining the transient response of a grounding system. This report, Volume 2, is a users manual and an installation and validation manual for the computer program SMECC (Substation Maximum Earth Current Computation Program). This program analyzes the electric current distribution among grounded structures inside and outside a substation for different fault conditions. The fault conditions are automatically selected by the program, or they may be specified by the user, or both. The fault condition resulting in maximum substation earth current is identified and reported. Data requirements for this program are: ground impedance, transformer data, transmission line data, transmission line grounding impedances, etc. The program provides four types of standard outputs: (1) a report of voltages and current flow in the unfaulted system, (2) a brief report of the maximum ground potential rise (worst fault condition), (3) a summary report of all fault conditions which have been analyzed by the program, and (4) a detailed report of voltages and current flow for a selected set of fault conditions.

Cutting costs through substation ownership  

SciTech Connect (OSTI)

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

Recent developments in subtransmission substations  

SciTech Connect (OSTI)

Equipment is described which offers the utility engineer flexibility in the layout and location of substations. It is possible with these designs to place HV connected substations directly into load centers and reduce the losses with connections at a lower voltage level. An added advantage of these designs are reduced expenses for engineering, site preparation, foundations, installation and interest payments due to the shorter time between equipment delivery and possible energization of a substation. Reduced maintenance, longer maintenance intervals, small gas leakage, are built-in advantages of this equipment.

Electric power substation capital costs  

SciTech Connect (OSTI)

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

Scoping study: Substation design workstation  

SciTech Connect (OSTI)

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

Ashland Area Support Substation Project  

SciTech Connect (OSTI)

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

East Grangeville Substation : Environmental Assessment.  

SciTech Connect (OSTI)

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

SciTech Connect (OSTI)

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

Transient electromagnetic interference in substations  

SciTech Connect (OSTI)

Electromagnetic interference levels on sensitive electronic equipment are quantified experimentally and theoretically in air and gas insulated substations of different voltages. Measurement techniques for recording interference voltages and currents and electric and magnetic fields are reviewed and actual interference data are summarized. Conducted and radiated interference coupling mechanisms and levels in substation control wiring are described using both measurement results and electromagnetic models validated against measurements. The nominal maximum field and control wire interference levels expected in the switchyard and inside the control house from switching operations, faults, and an average lightning strike are estimated using high frequency transient coupling models. Comparisons with standards are made and recommendations given concerning equipment shielding and surge protection.

Substation evaluation using Diagnostic Logic System (DIALOG)  

SciTech Connect (OSTI)

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

Substation automation -- a ``bottoms up`` approach  

SciTech Connect (OSTI)

The proliferation of multi-purpose intelligent electronic devices in substations brought the availability of abundant and often overlapping data at the substation. This data can be used for improving the operation and maintenance of the substations and the entire power system. The objective of substation automation is to use technology to gather, consolidate and utilize this data for increasing the efficiency of power system operation and maintenance. Often automation functions are developed and offered around the capabilities of the preferred hardware and software of the integrator. Emphasis is placed on hardware, software and communication protocols rather than need, methodology and application. This can result in over-automation with complex, expensive and ineffective systems, or under-automation that fails to achieve the user`s objectives. The objective is to select appropriate hardware, software and methodology to build the most cost effective system to get the desired results. This paper describes steps to ensure the successful implementation of substation automation.

High voltage electric substation performance in earthquakes  

SciTech Connect (OSTI)

This paper examines the performance of several types of high voltage substation equipment in past earthquakes. Damage data is provided in chart form. This data is then developed into a tool for estimating the performance of a substation subjected to an earthquake. First, suggests are made about the development of equipment class fragility curves that represent the expected earthquake performance of different voltages and types of equipment. Second, suggestions are made about how damage to individual pieces of equipment at a substation likely affects the post-earthquake performance of the substation as a whole. Finally, estimates are provided as to how quickly a substation, at various levels of damage, can be restored to operational service after the earthquake.

Earth resistivity measurement near substation ground grids  

SciTech Connect (OSTI)

Proper substation grounding grid design requires good, accurate soil resistivity measurements. This data is essential to model the substation ground grid to design a safe ground grid with a satisfactory ground grid resistance at minimum cost. For substations with several decades of service, there is some concern that a grid may have deteriorated, been damaged during equipment installation or excavation, or that initial soil resistivity measurements were lost or may not have been correctly performed. Ground grid conductors change the substation surface voltage distribution. Any voltage measurements taken at the complete substation will also vary from the tests made without conductors present. During testing, current was injected in the soil by probes placed near the ground grid. The current tends to follow the ground grid conductors since copper is a far better conductor than the soil it is placed in. Resistance readings near grids will be lower than readings in undisturbed soil. Since computer models were unavailable for many years, analyzing the effect of the grid conductors on soil resistivity measurements was very difficult. As a result, soil resistivity measurements made close to substations were of little use to the engineer unless some means of correcting the measured values could be developed. This paper will present results of soil resistivity measurements near a substation ground grid before and after a ground grid has been installed and describes a means of calculating the undisturbed soil model.

Experimental adoption of RCM in EDF substations  

SciTech Connect (OSTI)

EDF, after testing Reliability Centered Maintenance (RCM) on systems used in nuclear power plants, has now successfully extended RCM to all of its nuclear power plants. In the light of this experience, EDF has committed itself to a pilot study on a line bay of a 400 kV substation in 1992. The RCM method as applied benefited from EDF`s policy of maintenance, introduced five years ago on all substations, which has enhanced prospects of reliability. The original feature in the selection of maintenance tasks was that it brought into play two criteria for failure assessment - frequency and seriousness - and two criteria for maintenance task selection - efficiency and facility. The final outcome of RCM as applied to substation maintenance is to categorize maintenance tasks into: (1) essential maintenance tasks, (2) optional tasks, depending on the type and location of the substation, as well as on factors relating to local management of maintenance policy, and (3) unnecessary tasks.

Ashland Area Support Substation Project : Environmental Assessment.  

SciTech Connect (OSTI)

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

Planning substation capacity under the single-contingency scenario  

SciTech Connect (OSTI)

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

The implementation of substation automation coordinated with numerical protection relaying  

SciTech Connect (OSTI)

During 1987 Eskom embarked on a process of defining user requirements in the area of substation control. This ultimately resulted in a project being established for the procurement and development of a new generation of substation control equipment. At the same time it was decided to establish a new generation of protection schemes for transmission substations, based on numerical protection relays. From the outset, a high degree of coordination was planned between the substation control and protection equipment. Development contracts were placed with suppliers during late 1990 for the protection schemes and during early 1991 for the substation control equipment. These contracts are nearing completion and the first large installations will commence during 1994. The Transmission Group has committed to employing this new technology in all new substations and all substations to be refurbished. This paper discusses the concept of coordinated substation control and protection and gives insight into implementation issues and functional compromises which had to be made to meet project deadlines.

Abstract-This paper describes methodology for the computation of the electromagnetic transients in the high voltage substations, taking into account transients on the substation grounding system. Simulation technology is based on the system decomposition. Interconnections between different subsystems are done in each time step using Thevenin equivalents. Frequency dependent impedance of grounding conductors is represented by the parallel combination of resistance-inductance branches, to enable simulation in the time domain. Lightning overvoltage computation is performed for one particular 123 kV high voltage substation.

Substation flood protection: A case study  

SciTech Connect (OSTI)

On July 18, 1996, the City of Naperville, Illinois encountered a substantial storm event ranging from nine to fourteen inches of rainfall across town in less than twelve hours, with the majority falling over a four-hour period. The watershed containing the City`s Westside substation encountered the most significant rainfall totals, resulting in a flood crest in the substation area of approximately thirteen inches of water. The station is a 138 kV substation, and the flooding of this station caused a power loss to approximately 60% of the City`s customers for more than eight hours. The water level posed no threat to yard equipment, however, within the substation control building, flood water shorted out control circuits and damaged transmission line relay systems. Crews worked round-the-clock for most of a week to return all transmission lines and transformers to normal service. The 15 kV switchgear ultimately had to be replaced due to recurring control circuit problems. Once the station was restored and the cleanup efforts underway, the City embarked on an evaluation to determine what condition or conditions allowed the flooding to occur, and what could be done in the future to avoid this problem to ensure that the customers of Naperville would not experience another service outage of this magnitude due to flooding.

Short proofs of the Quantum Substate Theorem  

E-Print Network [OSTI]

The Quantum Substate Theorem due to Jain, Radhakrishnan, and Sen (2002) gives us a powerful operational interpretation of relative entropy, in fact, of the observational divergence of two quantum states, a quantity that is related to their relative entropy. Informally, the theorem states that if the observational divergence between two quantum states rho, sigma is small, then there is a quantum state rho' close to rho in trace distance, such that rho' when scaled down by a small factor becomes a substate of sigma. We present new proofs of this theorem. The resulting statement is optimal up to a constant factor in its dependence on observational divergence. In addition, the proofs are both conceptually simpler and significantly shorter than the earlier proof.

INSITE: An emerging standard for substation monitoring  

SciTech Connect (OSTI)

The functions of the INSITE Substation Apparatus Monitoring System can be broken into two, somewhat arbitrary categories. (1) Data acquisition, storage and communications, (2) Data analysis and apparatus condition assessment. We have defined the first set of functions as comprising the {open_quotes}platform{close_quotes}, the second as an {open_quotes}application{close_quotes}. We have made the distinction to encourage users to contemplate other possible {open_quotes}applications{close_quotes} which may be implemented using the platform. The intent of this paper is to describe in detail the platform functions. The requirements for the platform derive from several overall goals of a substation apparatus monitoring system: (1) Comprehensive: The ability to monitor all important types of substation apparatus, combined with all the tools - the sensors, the Data Acquisition Unit, and the analysis and communications software - for an on-line, real-time condition assessment of your equipment, with critical information at everyone`s fingertips. (2) Dependable: Built-in self-diagnosis that assures optimum system performance. (3) Reliable: From an extremely hot to extremely cold environment, capable of functioning reliably in electrically noisy substations. (4) Expandable: Easily upgradable to accommodate additional sensors available today and any new types developed tomorrow - as well as new software, for monitoring other equipment down the road. (5) Open: The ability to accept non-Doble supplied sensors - with future capability for integrating RS-232-compatible intelligent sensors. (6) Complementary: Compatibility with existing DTA technology, for example, making comparison of both out-of-service and in-service data possible. (7) Easy-to-Use: A Windows application with user-friendly pull-down menus, simple icons and buttons, and dialog sessions that can be mastered easily. On-line Help is also available.

Modeling and Simulating Blast Effects on Electric Substations  

SciTech Connect (OSTI)

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

Environmental Assessment of Proposed Filbert Substation and Tap Project.  

SciTech Connect (OSTI)

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

Finite element analysis of substation composite insulators  

Science Journals Connector (OSTI)

Composite insulators are rapidly replacing their porcelain counterparts in electrical substation applications. These insulators consist of a glass-reinforced polymer (GRP) rod, with two metal end fittings radially crimped onto the ends of the rod during assembly. In this paper, axisymmetric finite element models are developed to evaluate the mechanical performance of composite insulators under externally applied axial compression. The analyses are performed by assuming both a perfectly bonded interface between the composite rod and the end fittings, and an imperfect interface which permits large relative sliding with Coulomb friction. Results indicate that the perfect interface model is unrealistic since it predicts singular stresses at the interface comer and an overall linear structural response. On the other hand, the imperfect interface model is found to simulate accurately the structural non-linearity caused by relative sliding of the GRP rod within the end fittings. The imperfect interface model has therefore been used to evaluate the effects of interface friction, and the extent of crimping, on the maximum load-bearing capacity of substation composite insulators.

Grizzly Substation Fiber Optics : Environmental Assessment.  

SciTech Connect (OSTI)

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

Testing of complex IEC 61850 based substation automation systems  

Science Journals Connector (OSTI)

The integration of multifunctional intelligent substation devices (ISDs), in complex substation or power plant automation systems, requires the development of methods and tools for their testing that will ensure the correct operation of protection, control, monitoring, recording and metering functions, under normal and abnormal system conditions. The new IEC 61850 standard for communication networks and systems in substations allows the development of high-speed peer-to-peer communications based distributed applications, based on multicast of status changes or sampled analogue values. This paper details the requirements for the testing of complex substation automation systems. The testing methods need to correspond to the functional hierarchy of the substation automation system. Functional element testing, integration and system testing are discussed. Systems with Substation Bus only, and with both Process Bus and Substation Bus, are considered. A method for the testing of both types of system is proposed, based on a specific order of system components testing. Solutions for the testing of the individual components of the IEC 61850 based system, as well as for the testing of distributed applications, are described at the end of the paper.

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

SciTech Connect (OSTI)

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

PP&L experience with substation reliability centered maintenance  

SciTech Connect (OSTI)

This paper is intended to present a summary of Pennsylvania Power & Light`s (PP&L) experience with substation Reliability Centered Maintenance (RCM). The purpose of this summary is to first explain the process used by PP&L to implement substation RCM, second to explain the differences that are apparent from the use of the classical RCM analysis as compared to the method used by PP&L, and third to provide several insights into the process.

Study of gas insulated substation and its comparison with air insulated substation  

Science Journals Connector (OSTI)

Abstract This paper basically evaluates the two types of substation namely AIS and GIS on the basis of the life-cycle cost method, reliability, and environmental effects. The problems of very fast transient oscillations (VFTO) faced in GIS and their possible solutions. It substantiates and supports the use of GIS over AIS with an in depth analysis. In the end, HIS (hybrid GIS) has been proposed as a solution to overcome drawbacks of both AIS and GIS and to use the advantages of both in a single system for the best results.

Transient performance of substation structures and associated grounding systems  

SciTech Connect (OSTI)

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

Application and field experience of a digital substation switch  

SciTech Connect (OSTI)

There has been an increase in the use of solid-state, microprocessor-based relays, fault recorders, meters, and programmable controllers; in transmission and distribution substations. These devices can be remotely interrogated or programmed, and can send reports back to a host computer through their RS-232 communications ports. These devices use a wide variety of communications software and protocols. Because these devices can be located in the substation yard, induced surges and voltages can be present on the communication lines. This can impair the ability to communicate over RS-232 lines, and even cause equipment damage. In addition. the distance from the control house to the substation yard can limit the use of standard RS-232 protocol. For greater system economy, several devices must use the same communications channel. This requires a means of reliably connecting several devices to the incoming and outgoing communications circuits. This paper describes a digital substation switch (DSS) that was designed for this application, and its initial installation and field experience at Savannah Electric. The DSS connects various meters, transmission relays, and distribution relays to PCs in remote locations through a voice-grade telephone circuit. In this application, the DSS uses a fiber loop to communicate with the devices in the substation yard.

Feasibility of thyristor controlled series capacitor for distribution substation enhancements  

SciTech Connect (OSTI)

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

Reliability and component importance analysis of substation automation systems  

Science Journals Connector (OSTI)

This paper aims to present a comprehensive technique to quantitatively assess the reliability of substation automation systems. The technique is based on the tie-sets methodology. In order to demonstrate the application of the proposed technique, a variety of substation automation architectures is first introduced. The associated reliability block diagrams as well as the exact system reliability are then given. The impacts and the degree of importance of various components on the reliability of substation automation systems are presented. Two suitable measures of importance are selected. The first is the Birnbaum’s measure used to determine the bottleneck of the system reliability. The second measure uses criticality importance to diagnose failures and generating repair or inspection checklists.

Criteria for phase-to-phase clearances of HV substations  

SciTech Connect (OSTI)

To facilitate uprating of HV substations, the paper re-examines line-to-line insulation design criteria. The basis for existing practices and the principles of line-to-line lightning surge overvoltage stresses are reviewed. Results of a digital study for a realistic substation are presented. The conclusions show that the line-to-line stresses, as limited by surge arresters, are substantially higher than line-to-ground stresses. This represents increased requirements as compared to existing standards. However, due to low protective levels of modern arresters, substantial reduction of line-to-line clearances is still feasible.

A short proof of the Quantum Substate Theorem  

E-Print Network [OSTI]

The Quantum Substate Theorem due to Jain, Radhakrishnan, and Sen (2009) gives us a powerful operational interpretation of the observational divergence of two quantum states, a quantity that is closely related to their relative entropy. Informally, the theorem states that if the observational divergence between two quantum states rho, sigma is small, then there is a quantum state rho' close to rho in trace norm, such that rho' when scaled down by a small factor becomes a substate of sigma. We present a new proof of this theorem. The resulting statement is stronger and its proof is both conceptually simpler and significantly shorter than the earlier proof.

Reduction of interference on substation low voltage wiring  

SciTech Connect (OSTI)

This paper describes test results and mitigation methods of electromagnetic interference (EMI) on control and low voltage circuits in substations caused by air disconnect switch operation. The tests are focused on a comparison between unshielded and shielded circuits from capacitively coupled voltage transformers (CCVT) and other equipment circuits in the vicinity. New test data are presented comparing unshielded and shielded cables and transient currents on all connections to the CCVT including the pedestal and ground strap. The paper gives a practical and understandable explanation of the causes of EMI in substations and how shielded cable and parallel ground conductors reduce interference. Design guidelines are listed in the Conclusion.

Acoustic modeling and simulation of an urban substation  

Science Journals Connector (OSTI)

Demographic growth has often resulted in a disorganized occupation of large urban areas. Regions which were previously empty started to be populated frequently resulting in an increasingly more common proximity between residential construction and industrial installations. As a consequence very serious environmental problems have occurred including those caused by acoustic emission from industrial installations. A common problem these days is the disturbance caused by electric substations closely positioned to residential buildings. The disregard for acoustic effects during the design stage can still be observed in some of the older substation designs particularly in areas previously far from city centers. In some countries such as Brazil a systematic acoustic evaluation of substations only started in the 1980s with the main bulk of the work still under development. This paper describes some of the joint work being carried out on noise control by the researchers of Universidade Federal de Minas Gerais and CEMIG (the state power administration). The initial definition of a series of acoustic elements followed by the discussion of the governing equations is considered. The computational implementation of the resulting model is presented aimed at the definition of the most convenient noise control strategy. Finally a few results obtained at a real substation are considered including some experimental results obtained during actual operation.

BE 400/18 kV Substation Renovation Project  

E-Print Network [OSTI]

The 400/18 kV SPS main substation was designed for the 400 GeV SPS project and was commissioned in 1974. It has been upgraded several times to form the present 400/66/18 kV SPS and LEP transmission power comprising 490 MVA and 240 MVAR installed power. The beginning of the LHC project and the obsolescence of the main elements, and consequently limited reliability, made it necessary to begin a complete renovation program. The new configuration of the substation will integrate the new compensator of reactive power efficiently into the 18 kV pulsed network. In this way the new compensator will facilitate the functioning of the pulsed network with the new loads and it will improve the performance of the electrical substation. The renovation program consists in a global reorganisation of the substation, with the total replacement of the 18 kV power equipment, a set up of new control and protection systems for the 18 kV and 400 kV section and the reconditioning of all the 400 kV equipment.

Reliability centered maintenance (RCM) for substations project overview  

SciTech Connect (OSTI)

An EPRI Tailored Collaboration project establishing guidelines and tools for implementing Reliability Centered Maintenance (RCM) in substations is nearing completion and final results are being presented at this Substation RCM Conference. The ultimate goal of this RCM project is to help utilities slash substation operations and maintenance costs by optimizing equipment maintenance intervals. Preventive maintenance (PM) programs typically have been developed on a component-by-component basis, relying heavily on equipment vendors` maintenance recommendations. RCM is a logical alternative to traditional PM programs. It is intelligent, common sense maintenance that is function-based rather than component-based. First developed by the airline industry in the 1960s and further developed and applied to the nuclear industry by EPRI in the 1980s, RCM ranks the importance of each function of a system, calculates the impact the loss of the function would have on the overall system, and drives the design of appropriate maintenance tasks for each function. The nuclear industry reaped savings of at least 25% by adopting RCM, and one utility that tried this approach for substation maintenance reported savings of 13% in one year.

Achieving low return temperatures from district heating substations  

Science Journals Connector (OSTI)

Abstract District heating systems contribute with low primary energy supply in the energy system by providing heat from heat assets like combined heat and power, waste incineration, geothermal heat, wood waste, and industrial excess heat. These heat assets would otherwise be wasted or not used. Still, there are several reasons to use these assets as efficiently as possible, i.e., ability to compete, further reduced use of primary energy resources, and less environmental impact. Low supply and return temperatures in the distribution networks are important operational factors for obtaining an efficient district heating system. In order to achieve low return temperatures, customer substations and secondary heating systems must perform without temperature faults. In future fourth generation district heating systems, lower distribution temperatures will be required. To be able to have well-performing substations and customer secondary systems, continuous commissioning will be necessary to be able to detect temperature faults without any delays. It is also of great importance to be able to have quality control of eliminated faults. Automatic meter reading systems, recently introduced into district heating systems, have paved the way for developing new methods to be used in continuous commissioning of substations. This paper presents a novel method using the temperature difference signature for temperature difference fault detection and quality assurance of eliminated faults. Annual hourly datasets from 140 substations have been analysed for temperature difference faults. From these 140 substations, 14 were identified with temperature difference appearing or eliminated during the analysed year. Nine appeared during the year, indicating an annual temperature difference fault frequency of more than 6%.

Effects of intentional threats to power substation control systems  

Science Journals Connector (OSTI)

Power station control and management systems represent key elements for guaranteeing the security of the power grid infrastructure. Intrinsically conceived to support the continuous provision of power in secure conditions, those systems today make intensive use of information and communication systems and are therefore exposed to related accidental and intentional cyber threats. This paper describes a simulation of cyber attacks conducted in the CESI RICERCA laboratory testbed on a prototypical substation control infrastructure with the purpose of testing their feasibility and illustrating their impact on the control system services. A set of attack scenarios targeting several subsystems has been experimented, with different simulated threat motivations and different degrees of impact on the global substation service. The paper reports some considerations about the consequences of the implemented attacks, focusing on different facets of the problem, in an effort to elucidate the full significance of the potential cyber threats.

Dynamic sub-transmission substation expansion planning using learning automata  

Science Journals Connector (OSTI)

This paper presents a new method to solve the dynamic sub-transmission substation expansion planning (SSEP) in electric power distribution networks. The method employs a new algorithm based on learning automata for optimization process. The developed algorithm includes different electrical constraints such as voltage drops, thermal limits, power flow and radial flow constraints. Moreover, prevalent cost indices are taken into consideration. The proposed method is used to solve the dynamic SSEP for Birjand city, center of South-Khorasan province of Iran, up to the year 2024. In addition, effects of the dynamic and pseudo-dynamic planning models are investigated at the study region and the obtained results are compared to those of genetic algorithm. Detailed numerical results and comparisons presented in the paper show that the proposed approach leads to proper solutions and can be used as an effective tool for the dynamic sub-transmission substation expansion planning in an actual large scale distribution network.

Substation based data interpretation techniques for improved power system management  

SciTech Connect (OSTI)

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

Optimal Design of Grounding System for HV / EHV Substations in Two Layered Soil  

E-Print Network [OSTI]

Abstract — Successful operation of entire power system depends to a considerable extent on efficient and satisfactory performance of substations. Hence substations in general can be considered as heart of overall power system. In any substation, a well designed grounding plays an important role. Since absence of safe and effective grounding system can result in mal-operation or non-operation of control and protective devices, grounding system design deserves considerable attention for all the substations. Grounding system has to be safe as it is directly concerned with safety of persons working within the substation. Main purpose of this work is designing safe and cost effective grounding systems for HV / EHV substations situated at such locations where soil of the substation site is not uniform. Here soil is considered to be horizontally stratified into two layers. Initially significance of two layered soil model is introduced and design methodology for design of substation grounding system is discussed. Next, two design problems have been solved by using newly developed software and results obtained here are verified with the help of Ground Grid Systems module of ETAP – professional software. Comparison of the results obtained by both the software shows nice agreement of the results given by ESGSD with those obtained from ETAP. Hence this software is found to be quite satisfactory tool in the field of design of grounding system for HV / EHV substations.

Integrating modified Delphi method with fuzzy AHP for optimal power substation location selection  

Science Journals Connector (OSTI)

Evaluation and selection of power substation location is an important strategic decision making problem for both public and private sector. The multi-dimensional, multi-criteria nature of the power substation location problem limits the usefulness of any particular single objective model. Studies have shown that electromagnetic radiations emanating from the high voltage lines and substations, pose serious adverse health consequences to living beings. In this study, social, technological, economical, environmental and site characteristics factors and sub criteria, have been derived to make the optimal power substation location selection decision more realistic and effectual. In this paper, an improved and more appropriate power substation location evaluation and selection model has been developed by integrating Modified Delphi method with Fuzzy Analytic Hierarchy Process (FAHP). A numerical example is presented to show applicability and performance of the proposed methodology followed by a sensitivity analysis to discuss and explain the results.

Power substation location selection using fuzzy analytic hierarchy process and PROMETHEE: A case study from Bangladesh  

Science Journals Connector (OSTI)

Abstract Electromagnetic radiations emanating from the high voltage lines and substations pose serious adverse health consequences to living beings. As a result, selection of power substation location is an important strategic decision-making problem for both public and private sectors. In general, many conflicting factors affect the appropriate substation location selection problem which adheres to uncertain and imprecise data. In this paper, a simple, systematic and logical scientific approach is structured to evaluate power substation location through integrating Fuzzy Analytical Hierarchy Process (FAHP) with the Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE). The proposed integrated approach provides more realistic and reliable results, and facilitates the decision-maker to handle multiple contradictory decision perspectives through eliminating the limitations of FAHP and PROMETHEE methods. To accredit the proposed model, it is implemented in a power substation location selection problem in Bangladesh.

Daily load profile and monthly power peaks evaluation of the urban substation of the capital of Jordan Amman  

Science Journals Connector (OSTI)

The hourly recorded power of an urban substation of the National Electric Power Company (NEPCO) in the capital of Jordan Amman is used to calculate the diversity and conversion factors of the substation. These factors are used to estimate the daily load power profile and the monthly peak power of the substation. The results show that the conversion factors are almost independent of the number of feeders in the substation, while the diversity factors vary in substations that have six feeders or less. The results show a good correlation between the estimated and actual recorded data of the daily load profile with less than 5% percentage error.

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

SciTech Connect (OSTI)

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

Environmental noise of a nuclear power plant and its substations  

Science Journals Connector (OSTI)

In order to fulfill government requirements for construction of a nuclear power plant an environmental noiseimpact as?assessment has been conducted. Ambient noise was measured continuously for 24 hour periods at the plant and substation sites and in the vicinity. Week long surveys were performed in each of the four seasons. A statistical interpretation of construction noise accounts for variability of construction equipment usage its location and range of sound pressure levels. Histograms of construction noise and measured ambient noise are added to obtain the statistical representation of the predicted construction ambient noise. Operational noise of the plant is similarly predicted. The predicted noise contours of both operation and construction noise are formulated on the topographic maps. Meteorologic and topographic effects on the noise data are discussed.

HEMP-induced transients in electric power substations. Final report  

SciTech Connect (OSTI)

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

Characterization of ferroresonant modes in HV substation with CB grading capacitors  

Science Journals Connector (OSTI)

This paper reports a ferroresonant experience involving inductive voltage transformers (VT's) in a 400 kV substation equipped with circuit breaker grading capacitors. Field measurements are presented and compared with ATP/EMTP simulation results, showing very good agreement. A parametric analysis has been performed to investigate the effect of the substation capacitance on the occurrence of ferroresonance. Fundamental frequency and sub-harmonic ferroresonant modes have been identified and compiled in a bifurcation diagram. The methodology presented can be used to create risk maps of avoidable switching operations or substation configurations.

Science Journals Connector (OSTI)

In this paper a novel approach for optimal location, sizing and determining the service areas of HV/MV substations in a long-range planning period using pseudodynamic methodology is presented. Costs of equipment, areas, cables in MV side and power loss are considered in cost function. Uncertainty in loads is modeled using LR fuzzy numbers in load points. For optimization procedure, genetic algorithm with a new coding is used. Load points splitting in each area between substations and infeasibility solutions are considered in search procedure. Based on this, a software was developed and integrated into an optimization tool for substation allocation. The software was applied in many cases with satisfactory results.

Modelling and analysis of protection and control applications in smart substation  

Science Journals Connector (OSTI)

The real-time transaction processing was a key and challenging technology to protect systems from various failures in smart substation. This paper introduces the time critical communication between the protection and control devices and the primary apparatuses in three-level communication network architecture based on IEC61850, and analyses the process of information exchange and delay requirement of Protection and Control (P&C) applications between level and level, bay and bay, station and station in smart substation. The generic model of the P&C applications was modelling by latency requirement on OPNET, then the simulation and discussion on using those models to construct IEC61850 network validated the real-time of the application model. In the meantime, the delay performance of the P&C application is analysed in scenarios multiple services sharing substation network, which is an attempt to discuss the possibility of establishing a smart substation network simulation platform on OPNET.

A simple approach to improve lightning performance of an uprated substation  

SciTech Connect (OSTI)

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

An Adaptive Fast Multipole Higher Order Boundary Element Method for Power Frequency Electric Field of Substation  

Science Journals Connector (OSTI)

An adaptive fast multipole higher order boundary element method combining fast multipole (FM) with a higher order boundary element method is studied to solve the power frequency electric field (PFEF) of substations. In this new technique, the iterative equation solver GMRES is used in the FM, where matrix-vector multiplications are calculated using fast multipole expansions. The coefficients in the preconditioner for GMRES are stored and are used repeatedly in the direct evaluations of the near-field contributions. Then a 500kV outdoor substation is modeled and the PFEF of the substation is analyzed by the novel algorithm and other conventional methods. The results show that, in computational cost and the storages capability aspects, the algorithm proposed in this study has obvious advantages. It is suitable for the calculation of the large-scale PFEF in complex substations and the design of electromagnetic compatibility.

Variable Voltage Substation Electric Fire and Emergency Response  

Broader source: Energy.gov [DOE]

Variable Voltage Substation Electric Fire and Emergency Response My question is from an emergency response perspective. You stated that it took ~ ½ for electricians to de-energize the electrical components before firefighters were allowed in to fight the fire. This delay causes more damage to equipment and potential propagation of the fire. Is there not a “master” breaker or switch? You’ve brought up a very good point. It gave me a good opportunity to discuss this with our Facilities Department and get a better understanding of the infrastructure upgrade plans. The direct answer to your question is “Yes, but…” Yes, there are “master” breakers and switches, but we can’t control them remotely. SLAC’s AC electrical distribution system at present is manual breakers – we have not installed the infrastructure to remotely control them (except see below). We recently underwent an upgrade to our Master Substation that will allow us to remotely control some high voltage breakers in the future, but we aren’t there yet. We do recognize the value in having this capability (and more importantly, our vulnerability in NOT having it), and have begun the preliminary planning to make this happen. One issue were are working on is cyber security for the power distribution networked infrastructure. Before we install the capability to remotely control the main electrical breakers, we are planning the infrastructure with our Information Technologies organization to ensure we have a robust secure network that is protected from unauthorized access. Once the cyber security issues are addressed and funded, we’re probably 5-10 years out from having remote operation capability due to limited resources to fund and install the infrastructure. Having said the above, we do have the capability of remotely opening the VVS Secondary Main Breakers – the ones that send power to the modulator distribution breakers - from our control room. Those breakers are integral parts of our safety systems in that interlock violation causes the breakers to open and remove power to the klystrons. But everything else is manual only. That remote operation capability would not have helped us in this case, as the VVS Secondary Main Breaker was the one that fried. We needed to open the breaker upstream of the VVS. Thanks for your interest. Let me know if I can provide further information.

Impact of electric vehicles on distribution substations: A Swiss case study  

Science Journals Connector (OSTI)

Abstract An increasing number of electric vehicles (EVs) will have a significant impact on the electricity grids. For target grid planning, it is essential to identify and quantify this impact in terms of local infrastructure overloads. We study the impact of EV charging loads on Swiss distribution substations under different penetration levels and pricing regimes. Unlike mainly conceptual studies focusing on generic distribution grids, we use real data—driving profiles matched to regional circumstances, Swiss substation capacity and load data in the high-voltage grid together with electricity prices—as the main data inputs. To reflect current regulation and contracting schemes, we apply decentral decision-making instead of central control. The results indicate that under a flat electricity tariff and EV penetration levels around 16% the current substation capacity will be sufficient to cover additional EV charging load. However, beyond penetration levels of 50% an increasing number of substations will be overloaded. More significantly, the introduction of dynamic electricity prices can further increase the risk of substation overloads. These results show that EV charging loads can also cause bottlenecks on substations in the high-voltage grid.

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

SciTech Connect (OSTI)

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

Fault diagnosis of electric railway traction substation with model-based relation guiding algorithm  

Science Journals Connector (OSTI)

Abstract Most diagnosis systems used in electric railway traction substation are expert systems based on experience, which cannot diagnose faults beyond experience and are very difficult for transplantation and maintenance. In this paper, the model-based diagnosis (MBD) with integration reasoning is firstly used for fault diagnosis of electric railway traction substation. Aiming at the structural characteristics and actual demands of traction substation, we propose a detailed application plan. Rules for element and system models are established. In addition, we propose a relation guiding algorithm (RGA) for searching candidates of minimal conflict set, in which the hidden messages of analytical redundancy relations can be made full use of and the searching space is reduced further. Taking the autotransformer (AT) traction substation in Hefei–Nanjing Passenger Link of China Railway as an example, we construct models for different device objects, and give the descriptions of system model in traction substation. Based on a sequence of fault observations, the fault diagnosis is tested with the proposed plan. The diagnosis result shows that the application plan with MBD and integration reasoning is feasible and effective for traction substation.

Conformational Diversity and Sub-states in Enzyme Catalysis Conformational Diversity and Sub-states in Enzyme Catalysis November 01, 2013 Enzymes are great biocatalysts, and have attracted significant interest for industrial applications (including cellulosic ethanol) due to their remarkable catalytic efficiencies. The understanding of factors that enable enzymes to achieve the high catalytic efficiency will have large impact through design of new and powerful biocatalysts. Unfortunately, the understanding of these factors have largely remain a mystery so far. Using joint computational-experimental methodology we have developed a unique technique named quasi-anharmonic analysis (QAA) for identification of conformational diversity and conformational sub-states associated with enzyme function. As a result of this approach we have been able to develop

Control of offshore marine substation for grid-connection of a wave power farm  

Science Journals Connector (OSTI)

Abstract To grid-connect an offshore wave power farm, an intermediate marine substation is suggested. As a part of the Uppsala University wave power project, a marine substation has been designed, assembled and deployed at sea. The substation is capable of connecting up to seven wave energy converters (WECs), and to transfer the power to the onshore 1 kV-grid. In this article, the control procedure for grid connection of the \\{WECs\\} is described step-by-step, and the practical implementations are presented. The system is designed with autonomous control and will connect or disconnect the WECs, depending on the sea state. Fault handling is taken into account, and grid power quality such as harmonic distortion and flicker are considered in the design. Experimental results are presented to verify the system functionalities.

Design of active loops for magnetic field mitigation in MV/LV substation surroundings  

Science Journals Connector (OSTI)

Abstract This paper deals with the application and optimization of active loops for the mitigation of the magnetic field generated by complex sources, especially MV/LV substations. Various active-loop configurations are proposed, which are analyzed in several regions located close to a particular MV/LV substation, and the optimum geometry and location of the loops are obtained together with the optimum current (magnitude and phase) to be injected into the loops. All this is performed by means of a genetic algorithm in order to reduce the average magnetic field inside the target volume (inspection volume) to the minimum. The performance of the proposed active loops is compared with that obtained via other well-known mitigation technique, such as conductive/ferromagnetic passive shields. The main results are analyzed, and the differences, in terms of performance, between the two shielding techniques, and their proper application to MV/LV substations, are highlighted.

Science Journals Connector (OSTI)

Abstract Jakarta is a metropolitan city that continues to strive to develop the capacity of its mass transport as other large cities in the world, primarily the development of the rail-based transportation. Indonesia Railway Company (PT Kereta Api (Persero)) had forecasted that there will be 1.2 million passengers per day on Jakarta in 2019. To meet these targets, it is necessary to adequate the infrastructure planning, especially the capacity of the DC substations which supply the electric power to the trains. This paper will demonstrate the strategy used to determine the point of placement of new DC substation and/or existing DC substation upgrades throughout the Jakarta area from 2013 to 2019. The current railway timetable and the future pattern of railway operation plan are used to predict the possibilities of peak load spots along the track.

Integrating fuzzy AHP with TOPSIS method for optimal power substation location selection  

Science Journals Connector (OSTI)

Electromagnetic radiations emanating from the high voltage lines and substations pose serious adverse health consequences to living beings. As a result, evaluation and selection of power substation location is an important strategic decision making problem for both public and private sector. In this paper, fuzzy analytic hierarchy process (FAHP) has been integrated with technique for order preference by similarity to an ideal solution (TOPSIS) method to develop an improved and more appropriate power substation location evaluation and selection model considering social, technological, economical, environmental and site characteristics factors and sub criteria. The proposed decision-making approach takes advantage of the synergy between these two well-known multi-criteria analysis (MCA) methods. A numerical example is presented to show applicability and performance of the proposed methodology followed by a sensitivity analysis to discuss and explain the results.

SciTech Connect (OSTI)

A maintenance optimization study for substation components can be most effective when Reliability Centered Maintenance (RCM) Analysis is combined with a Predictive Maintenance (PDM) Assessment. If the two processes are performed concurrently, the benefit-to-cost ratios for each is increased. Also, the cost of implementing RCM recommendations for condition monitoring can be minimized, while maximizing their impact at the same time. This paper presents the essential elements of both the RCM and PDM processes, and describes how they work together in a substation environment as a comprehensive maintenance assessment tool. Descriptions of recent experiences are also included.

Implementation of superconducting fault current limiter for flexible operation in the power substation  

Science Journals Connector (OSTI)

Abstract The concentration of large-scale power loads located in the metropolitan areas have resulted in high fault current levels during a fault thereby requiring the substation to operate in the double busbar configuration mode. However, the double busbar configuration mode results in deterioration of power system reliability and unbalanced power flow in the adjacent transmission lines which may result in issues such as overloading of lines. This paper proposes the implementation of the superconducting fault current limiter (SFCL) to be installed between the two substation busbars for a more efficient and flexible operation of the substation enabling both single and double busbar configurations depending on the system conditions for guaranteeing power system reliability as well as fault current limitations. Case studies are being performed for the effectiveness of the SFCL installation and results are compared for the cases where the substation is operating in single and double busbar mode and with and without the installation of the SFCL for fault current mitigation.

Analysis on heat loss characteristics of a 10 kV HTS power substation  

Science Journals Connector (OSTI)

Abstract A 10 kV High Temperature Superconducting power substation (10 kV HTS substation), supported by Chinese State 863 projects, was developed and has been running to supply power for several factories for more than two years at an industrial park of Baiyin, Gansu province in Northwest China. The system of the 10 kV HTS substation compositions, including a HTS cable, a HTS transformer, a SFCL, and a SMES, are introduced. The SMES works at liquid helium temperature and the other three apparatus operates under liquid nitrogen condition. There are mainly four types of heat losses existing in each HTS apparatus of the 10 kV HTS substation, including AC loss, Joule heat loss, conductive heat, and leak-in heat from cryostat. A small quantity of AC loss still exists due to the harmonic component of the current when it carries DC for HTS apparatus. The principle and basis for analysis of the heat losses are introduced and the total heat loss of each apparatus are calculated or estimated, which agree well with the test result. The analysis and result presented are of importance for the design of the refrigeration system.

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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.

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

Comment on Relative Magnetic Substate Amplitudes in Foil Excitation of Fast Hydrogen Atoms  

Science Journals Connector (OSTI)

If the particle-foil interaction potential governing production of H atoms coherently excited by passage through thin foils obeys the LS coupling scheme applied by Macek (conservation of z components of total orbital and spin angular momenta of the entire particle-foil system, and incoherence of final states of foil constituents), the ad hoc assumption that random phases prevail among the hydrogenic magnetic substate amplitudes invoked in the interpretation of certain recent experiments is avoided. Arguments concerning relative phases of states of different orbital angular momentum are unaffected.

Measurement system design and implementation for grid-connected marine substation  

Science Journals Connector (OSTI)

A marine substation for a grid-connected wave power plant has been designed and constructed at Uppsala University. The measurement system for the substation has been developed from basics, and the procedure is described in this article. Subsea electrical installations set high constraints on the control and data acquisition systems used, and traditional GSM networks and GPS time synchronization are difficult and inefficient. These circumstances exclude many well-proven methods to be utilized. A compactRIO-based system, with integrated real-time controller and Field-Programmable Gate Array chip, is chosen as most suitable for this task. The system is designed to meet the special requirements encountered in this unusual application, including large data sampling, grid connection control and protection systems. The system is communicating to shore via a subsea copper cable and single-pair high-speed digital subscriber line modems. The design was successful and full-fills all the system requirements. The aim of the article is to provide future researchers with a good design and implementation procedure for setting up large measurement systems.

Video surveillance-based insulator condition monitoring analysis for substation monitoring system (SMS)  

Science Journals Connector (OSTI)

Video surveillance (VS) of electric power lines along with its accessories such as insulators has emerged as a potential alternative for the traditional practice of on-site physical detection. There has been a paradigm shift in electric substation automation using substation monitoring system (SMS). Since the damaged insulators severely affect the distribution system performance in terms of reduction in voltage as well as flow of leakage currents, therefore, the incorporation of insulator health as an augmented feature in SMS would improve the quality and reliability of power supply. By using information technology, the automation of insulator monitoring of power system is made faster to recover the fault system immediately. This paper presents a methodology for insulator condition analysis based on VS combined with wavelet coefficient differentiator (WCD) for SMS purposes. The case studies and results contained herein corroborate the efficacy of the proposed methodology to dispense with the conventional on-site physical methods, which are not only tedious, but also time-consuming.

Measurement of the acoustic pressure distribution occurring around an aerial substation adjacent to apartment buildings  

Science Journals Connector (OSTI)

The subject matter of the research work presented in this paper refers to the measurements of the values of the acoustic pressure levels (noise) occurring around a main feeding?point aerial substation adjacent to apartment buildings. The paper presents the values of the noise accompanying the particular power devices mainly transformers during their regular operation. The main aim of this research work was the comparison and assessment of the acoustic pressure values measured with the permissible values defined by environmental standards binding in Poland. The research analysis carried out proved that during a long?term operation of power appliances installed in substations the acoustic pressure level that they emit into the environment is not constant but is subject to changes. Thus the increase of the noise level above the permissible values can be the cause of violation of environmental standards. Due to a significant increase of people's awareness and readiness to claim their rights the main consequence of violating the standards is a growing number of claims. Therefore it is imperative that the level of the acoustic pressure be monitored during routine tests especially around high?power transformers.

Substations for Decentralized Solar District Heating: Design, Performance and Energy Cost  

Science Journals Connector (OSTI)

Abstract The development of solar district heating is gaining more and more interest, but, in some case the space available for the integration of solar collectors on the ground is limited and the use of decentralized systems is necessary. For decentralized solar district heating systems different hydraulic schemes at the substation level, with or without local use of solar energy, are possible. The present paper detailed an advanced study on decentralized solar district heating system using dynamic simulation software. Nine different hydraulic schemes for substations have been investigated with a return to return feed in. For each scheme many parameters that influence the performance of the solar installation have been studied such as the district heating network return temperature, the solar collector area and the type of solar collector (low temperature or high temperature solar collector). The comparison between the different hydraulic schemes is based on thermal efficiency but also on solar energy cost using the methodology of the Levelized Cost Of Energy (LCOE).

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

Experimental evaluation of radiator control based on primary supply temperature for district heating substations  

Science Journals Connector (OSTI)

In this paper, we evaluate whether the primary supply temperature in district heating networks can be used to control radiator systems in buildings connected to district heating; with the purpose of increasing the ?T. The primary supply temperature in district heating systems can mostly be described as a function of outdoor temperature; similarly, the radiator supply temperature in houses, offices and industries can also be described as a function of outdoor temperature. To calibrate the radiator control system to produce an ideally optimal radiator supply temperature that produces a maximized ?T across the substation, the relationship between the primary supply temperature and outdoor temperature must be known. However, even if the relation is known there is always a deviation between the expected primary supply temperature and the actual temperature of the received distribution media. This deviation makes the radiator control system incapable of controlling the radiator supply temperature to a point that would generate a maximized ?T. Published simulation results show that it is possible and advantageous to utilize the primary supply temperature for radiator system control. In this paper, the simulation results are experimentally verified through implementation of the control method in a real district heating substation. The primary supply temperature is measured by the heat-meter and is shared with the radiator control system; thus no additional temperature sensors were needed to perform the experiments. However additional meters were installed for surveillance purposes. To maintain a stable indoor temperature at times when the primary supply and outdoor temperatures deviates from their assumed relation, the radiator system flow must be controlled by an additional control-loop. The results confirms that it is possible to control the radiator system based on the primary supply temperature while maintaining comfort; however, conclusions regarding improvements in ?T were hard to distinguish.

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

SciTech Connect (OSTI)

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

Redesign process of a 765 kVRMS AC substation connector by means of 3D-FEM simulations  

Science Journals Connector (OSTI)

Abstract This paper shows the capabilities of applying the three-dimensional finite element method (3D-FEM) for designing complex-shaped substation connectors to operate at 765 kVRMS AC. To check this methodology, it was analyzed the feasibility of upgrading a 400 kVRMS substation connector to operate at 765 kVRMS. However, both experimental and simulation results conducted according to the ANSI/NEMA CC 1-2009 standard concluded that although it passed the visual corona test, to ensure a wide safety margin it was desirable an improvement of the electrical behavior of such connector. It was shown that FEM results allowed detecting the peak stress points of the connector regarding the electrical stress thus allowing applying a corrective action. Then, two possible solutions were analyzed, i.e. the use of corona shields and the redesign of the connector assisted by 3D-FEM simulations. Results presented in this work show that both approaches have an excellent behavior in reducing the electric field strength on the connector surface. However, to make the final decision, the production cost of both alternatives was analyzed, thus favoring the redesign option. Next, the redesigned version of the substation connector was manufactured and tested. Experimental results conducted in a high voltage laboratory verified the effectiveness of the methodology and the potential of the proposed system to act as an advanced design tool for optimizing the behavior of complex-shaped substation connectors. Thus, this system allows assisting efficiently the design process while permitting constraining the economic costs.

Voltage sags, whether they occur in transmission or distribution systems, may severely damage the loads connected to the power system. As these problems could cost a great deal financially, electric utilities are very interested in finding the origins of sags, that is, whether they have been originated in the transmission network (high voltage (HV)) or in the distribution system (medium voltage (MV)). In addition to the needs of utilities and regulators, many researchers have been prompted to develop reliable methods to properly classify sags. Several of these methods, based on classifying meaningful features extracted from data and waveforms, have been proposed in the literature. Unlike those methods, though, we propose a systematic transformation of data, based on multiway principal component analysis (MPCA), to develop a new voltage sag classification procedure. Sampled voltage and current waveforms of previously registered sags are used together with the MPCA technique to obtain a lower dimensional model. This model is then used to project new sags and classify them according to their origin in the power system. Different classification criteria and parameters are examined to maximize the classification rates of not yet seen sags. Applying the proposed method to real sags recorded in substations demonstrates its applicability and power.

Studies of parallelism in distribution networks served by different-source substations  

Science Journals Connector (OSTI)

Despite the fact that the distribution systems usually operate radially, there is the possibility of changing the topology by opening or closing the switching equipment [1]. This change can occur in two situations. In the first one, when one tries to optimize the configuration of the electric network, aiming to achieve lower voltage drop and loss indices, as well an increased reliability. In the second one, when one needs to transfer load from a feeder to another, as result of some contingency or a planned disconnection. In both situations, one has to take into account that multiple switchings in the networks can cause some disconnections for customers, during a short period of time, especially when the feeders are served by different-source substations. These interruptions cause undesirable energy continuity levels for customers, who are more demanding in relation to the electric power supply quality. This context has motivated this paper, whose proposal is the development of a methodology to analyze the technical feasibility of parallelisms in distribution networks by using the Alternative Transient Program (ATP), thus avoiding disconnections for customers. As a result, case studies in AES Sul's concession area, power distribution utility, will be presented.

Rural community noise caused by 345/138 kV substation transformer  

Science Journals Connector (OSTI)

Residents 360 m (1200 ft) from a large (6 × 8 × 4.5 m high) 345/138 kV transformer installed in a new power substation in a rural setting complained of its noise emission especially at night. Octave band and 24?h A?weighted noise measurements were made. The 120?Hz sound level was found to be 90 to 105 dB at the transformer surface. Transformer noise emission did not vary significantly with transformer loading or time of day. The distant (360 m) noise level was from 40 to 47 dBA (N?30 to N?45) depending on intervening terrain and time of day. In calm summer air the annoying sound was found to be in the 125?Hz band at the residence beyond a vegitated rise and 250 to 500 Hz for a residence with line?of?sight contact over a shallow depression. The line?of?sight resident's complaint that the noise was greatest at night was corroborated by the 24?h measurement. That noise level was found to be typically 38 dBA from 11 a.m. to 7 p.m. and 45 dBA from 9 p.m. to 6 a.m. It is postulated that the depression accumulated cool air at night thus refracting the sound onto that site. Recommendations for a noise barrier wall was made to the power company operator.

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

SciTech Connect (OSTI)

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

A comparative study on substation types and network layouts in connection with low-energy district heating systems  

Science Journals Connector (OSTI)

The study deals with low-energy District Heating (DH) networks operating in low temperatures such as 55 °C in terms of supply and 25 °C in terms of return. The network layout, additional booster pumps, and different substation types such as storage tanks either equipped or not equipped in domestic hot water production site were examined. Effects of booster pumps on pipe dimensions in the latter case were investigated. Temperature drops during the summer months due to low heat demands of consumers were explored. Use of approaches such as looped networks and branched network layouts with bypasses for end-consumers were also studied, heat loss from these networks and the drop in temperature in the heat-carrier-supply medium being compared.
