    The short-term objective of the work described is to develop ground and knowledge-based systems integrated with actual electric power system breadboards and testbeds to demonstrate the viability of advanced automation approaches for spacecraft onboard and ground-support applications. Initially, such systems would be used primarily in advisory capacities. As confidence is gained in their operation,... View full abstract»

    A survey made to identify the magnitude and severity of the simultaneous transfer problem and how electric utilities are attempting to cope with this problem is described. Its purpose was to assess the industry's need, experience, and concerns in the area of simultaneous transfer capability analysis. The authors describe the survey preparation along with the results from the mail survey and follow... View full abstract»

    The author describes a series of computer programs that he has developed for finite-element electric and magnetic field calculations since 1970. All the modules for generation of elements, solution of equations, graphics, etc. are contained in the programs, which are supplied completely on one or two diskettes. The programs are adapted for use on personal computers.<> View full abstract»

    Multiported remote terminal units (RTUs) instantaneously provide data to area and regional masters and/or neighboring utilities without the time delay associated with master-to-master communication or the cost of multiple RTUs. Thus RTUs improve capabilities and contribute to reducing the cost of energy management system (EMS) implementation. The development of advanced protocols to reduce RTU exp... View full abstract»

    A description is given of an interactive automatic generation control (AGC) simulator developed under EPRI's Power Plant Performance Instrumentation Project (RP1681/2153). It was developed to test and compare economic dispatch algorithms, which might be able to show improvement over standard economic dispatch algorithms if accurate unit information were available. The value of such improvements to... View full abstract»

    Harmonics analysis, unlike the more traditional analysis techniques, such as load flow, must be solved at numerous frequencies. Much of what could once be ignored at 50 or 60 Hz can no longer be ignored. A program called V-HARM, which runs on PCs, has been developed for this analysis. The evolution of V-HARM and its solution technique and analysis procedure are described. The program is menu-drive... View full abstract»

    The authors discuss systems designed specifically for industrial customers of electric utilities, which provide functions similar to those of electronic monitoring and control systems used by utilities but are tailored to meet the specific requirements of an industrial power system. They describe the system architecture of such systems and some of its features and examine the benefits obtained fro... View full abstract»

    The use of power-line carriers to transport signals between protective relaying equipment at line terminals is discussed. The purpose is to determine which line section is faulted. Critical factors for reliable carrier performance are identified. Automatic carrier testing using programmable controllers is examined, and installation of the programmable controller carrier checkback is described. The... View full abstract»
