    The paper covers the development of the distribution system in the south-west of England from nationalisation up to the present time. Early rural electrification problems and developments are discussed, together with standardisation during the period of rapid load and system growth. The influence on an Area Board of the change in the price of basic fuels, together with the effects of recession and... View full abstract»

  • Reliability and economic assessment of generating systems containing wind energy sources

    Publication Year: 1985

    There is much interest in using renewable energy sources, such as wind, wave and solar, to generate electrical energy. Unfortunately, such energy sources are intermittent, and, therefore, conventional sources must still be available to meet the demand during quiescent periods. Hence, the reliability and economic assessment of these novel sources cannot be made using standard capacity-replacement-b... View full abstract»

  • Power system stabiliser for large disturbances

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (736 KB)

    An adaptive stabiliser that supplements the excitation control signal of a synchronous machine is presented in this paper. A pole-shifting algorithm that radially shifts the poles towards the origin is described. Also, because of the nonlinear characteristics of the synchronous machine, the algorithm is modified such that the system identification is turned off for a short period following the ons...

    The paper considers a novel way of scheduling generations and loads for enhancing stability of overall power systems. Based on a so-called structure-preserving model, an algorithm is proposed for correcting the dynamically insecure system. The algorithm proposed aims at online computer applications. In the event of an emergency, the percentage load to be shed and the busbars which are affected wou... View full abstract»

  • Variable-structure-system control applied to AGC of an interconnected power system

    Publication Year: 1985, Page(s):23 - 29
    Cited by:  Papers (6)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (596 KB)

    A control scheme based on a variable-structure-system concept is applied to the problem of automatic generation control of interconnected power systems. The proposed algorithm is simple and easy to implement. The effect of generation-rate-constraint nonlinearity on the dynamic performance of the system for reheat- and nonreheat-type steam turbines is also studied. A comparison of the conventional ...

  • Placement of static compensators for stability improvement

    Publication Year: 1985, Page(s):30 - 35
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (820 KB)

    A computationally efficient means of determining the location of a static VAR compensator, to maximise its influence over damping of electromechanical oscillations, is presented. The location criterion, which is independent of the ultimate control scheme to be used, is applied to two-machine systems. An extension of the criterion to multi-machine systems, using modal analysis, is demonstrated on a... View full abstract»

  • RF power injected into the DC yard by an HVDC convertor pole

    Publication Year: 1985, Page(s):36 - 40
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (612 KB)

    A new estimate has been made of the RF power injected by an HVDC convertor pole into the DC yard. The RF power levels measured provide a design basis for either an active or passive RF filter for the protection of a power-line carrier system of a convertor station of this type.

  • M - to N-phase transformer models in phase co-ordinates

    Publication Year: 1985, Page(s):41 - 48
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (786 KB)

    M- to N-phase transformers (M ¿¿ N) are considered in the phase co-ordinate frame of reference. Equivalent circuits are derived for zig-zag, Scott, T-T and star-double-star transformers, and the connection tables are given for use in assembling the nodal-admittance-matrix terms in the usual way for power network analysis. The paper concludes with an example of a polyphase load-flow analysis of a n... View full abstract»

  • Predetermination of lateral length to prevent overvoltage problems due to open conductors in three-phase systems

    Publication Year: 1985, Page(s):49 - 55
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (856 KB)

    The opening of one or two conductors in three-phase circuits supplying an ungrounded transformer produces a steady-state overvoltage due to ferroresonance between the lateral capacitance and the transformer nonlinear inductance. Available methods of determining the conditions under which such an overvoltage may occur are mostly based on experimental studies, and hence are limited in application to... View full abstract»
