    The salient features of the design and construction of an analog computer for the study of HV-dc transmission systems are described. The special modeling techniques which permitted a relatively low power base simulator which could be interconnected with the ac Transient Network Analyzer are outlined. The completed simulator is a useful tool for the systems planning engineer whereby system and control can be studied in all their complexity while maintaining a reasonable dimension on the output time.

    Interest in HV-dc transmission has fostered development of techniques for the study of dc systems in parallel with extensive ac systems. A digital computer program for the study of steady-state and transient behavior of combined ac/dc systems has been developed, including a detailed representation of a dc link, the capability of representing a large-scale interconnected ac system, and representation of the transient performance including the mutual effects between the ac and dc systems. The evolution and content of the program, together with representative results of studies are presented. View full abstract»

    The design and layout for one of the first HV-dc converter stations (1440 MW) in the United States to be located near "The Dalles," Ore., is described. The coverage ranges from the incoming 230-kV ac buses with the harmonic filters, grid timing supply, etc., through the converter transformers, valve groups, and control, to the ±400-kV outgoing dc buses with the smoothing reactors. The dc system, of which this terminal is a part, will have an 827-mile overhead transmission to the southern terminal at Los Angeles, Calif. View full abstract»

  • Zone-Packaged Ground Distance Relay II - Design and Performance

    A new concept in ground distance fault detection has been reduced to practice in a relay, designated as Type SDG. The relay is a zone-packaged unit which gives the engineer flexibility when designing the relaying system for multiple-zone primary and backup protection. It is an impedance-type relay which has a modified mho circle characteristic when plotted on an R-X diagram. Special circuitry prevents incorrect operation due to over-frequency line oscillations, loss of voltage, or double-phase-to-ground faults. Thus, high-speed operation¿7 to 11 ms is obtained without sacrificing security. View full abstract»

  • The Effects of Availability Upon Installed Reserve Requirements

    Publication Year: 1966 , Page(s): 1135 - 1144
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (2002 KB)  

    The importance and effects of reliable forced outage and availability data upon installed capacity reserve requirements for an electric utility system are discussed. The effects are discussed in relationship to a utility system's ability to maintain equipment and to provide capacity to replace capacity which may be forced out of service due to emergency failures. No attempt is made to treat the subjects of load forecasting, spinning reserve, and tieline regulation. A brief resume of the development and usage of probability methods applied to the determination of forced outage requirements is included. View full abstract»

  • The Relationship Between Summer Weather and Summer Loads - A Regression Analysis

    When summer air conditioning contributes significantly to an electric utility's system peak load, it is useful, for load forecasting purposes, to separate total system load into two components: temperature-sensitive load and nontemperature-sensitive load. Examination of historical data indicates that temperature-sensitive loads depend not only upon coincident but also antecedent weather conditions. Regression analysis techniques using a digital computer have shown that the combined effect of these weather conditions can be expressed by one composite weather variable (WV). Total system load can then be expressed as Basic Load plus the product of WV times a coefficient of air-conditioning saturation. Results obtained by application of this method to historical data (1949-1964) of Public Service Electric and Gas Company are presented. View full abstract»

    This is a companion paper to an earlier one.1 The computer program described is divided into three parts: a) the determination of the coefficientsfor(l), (2), and (4) of Watchon1 for the best fit to the calculated cost and plant pumping ratio data, b) the determination of the lowest average unit investment cost, and other pertinent information, to be shown later, for each of the potential sites for various conditions, and c) the arrangement of the results of part b in the order of preference. All the programs are written in Fortran for the 7074 computer. View full abstract»

  • Some New Aspects on Load-Flow Calculation: I - Impedance Matrix Generation Controlled by Network Topology

    Refined load flow calculation methods will exploit topological properties of the underlying network. An exact topological criterion, as well as a powerful handy approximation for most economic generation of the impedance matrix, are presented. Additional advantage may be taken from topology-controlled selection of reference bus and from appropriate insertion of artificial nodes. The new method has been carefully checked on a variety of power system networks of different size, the 30-, 57-, and 118-node standard test systems, authorized by IEEE Computer Application Subcommittee, among others.

    This paper describes the mechanical brush gear designed for carrying the 1.6 million-ampere 1-second pulses from the rotors of the Canberra homopolar generator. Current density in the copper graphite brushes rises to about 10 000 A/in2 at full current. The brushes are also required to operate at rubbing speeds of up to 33 000 ft/min. The experiments that were made to set the design limits for the brushes and the results obtained from these experiments are described; the design requirements and details of the brush gear as manufactured are given; and their operation in the homopolar generator is discussed.
