    The paper derives techniques for online and offline computer analysis of the power system in the presence of large amounts of stochastic-source (wind, solar, tidal etc.) generation and develops an extension of the probabilistic simulation (Beleriaux-Booth) technique for use in generation expansion planning. The online techniques are employed for the assessment of spinning reserve and unloadable ge... View full abstract»

  • Cluster analysis of power-system networks for array processing solutions

    A clustering algorithm is described for the decomposition of networks using a distributed array processor. The algorithm is applied to the analysis of medium-sized networks, and the way in which the clusters relate to power-system load-flow analysis is shown. A sparsity oriented development of the method suitable for the analysis of large networks is derived. View full abstract»

    The paper develops methods by which groups of individual loads supplied from power networks may be represented equivalently in composite form in evaluations of dynamic modes of network operation and the limiting conditions of stable system operation related to them. Central to the methods developed is a formal, parameter-identification procedure by which values are found for the parameters which d... View full abstract»

  • The mismatch theorem and second-order load-flow algorithms

    Publication Year: 1985, Page(s):189 - 194

    The purpose of this paper is to shed light on and compare the second-order load-flow (SOLF) methods. To do this, the mismatch theorem is developed, which relates the neglected terms for a Taylor series, during an iteration to the mismatches at the end of that iteration. This theorem suggests improvements on the reported SOLF methods. It is shown that all these second-order methods propose either r... View full abstract»

  • The production of residual currents due to harmonic loading

    Publication Year: 1985, Page(s):195 - 201
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (753 KB)

    The connection of nonlinear loads such as thyristor drive systems to the power system creates waveform distortion due to the harmonic currents which are injected. The propagation of the harmonic currents throughout the power system is governed by a number of factors including resistance, inductance and capacitance of circuit elements and the system load. The harmonic current at the nonlinear load ... View full abstract»

  • Effect of AC system impedance on the regulation and, hence, the stability margin of HVDC schemes

    Publication Year: 1985, Page(s):202 - 207
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (609 KB)

    In the paper, a mathematical analysis of how the AC system network parameters, including the harmonic filter impedances, affect the regulation of an HVDC scheme, is given. The regulation and, in particular, the sign of the regulation will be one of the parameters which will affect the stability of the overall scheme. The paper shows how increasing the impedance at both the rectifier and inverter b... View full abstract»

  • Analogue simulation of lightning induced voltages and its application for analysis of overhead-ground-wire effects

    Publication Year: 1985, Page(s):208 - 216
    Cited by:  Papers (12)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (880 KB)

    An analogue simulation method has been developed for study of the phenomena of lightning induced voltages by using a 1 : 200 scale model. It has been verified that the thus produced lightning induced voltage waveform is in good agreement with the waveform obtained by numerical analysis. By using this method, a study has been made of the lightning induced voltage shielding effects of various types ... View full abstract»

  • Sensitivity analysis of lightning performance calculations for transmission lines and substations

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (766 KB)

    Analysis has been made of the influence of various lightning parameters on the computed risk of line and substation insulation failure. The analysed lightning current parameters are the mean value and the standard deviation of the current magnitude, as well as the mean value and the standard deviation of current wavefront steepness in an assumed log-normal frequency distribution. The influence of ... View full abstract»

  • Current instability and chopping with arcs in series

    Publication Year: 1985, Page(s):224 - 228
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (555 KB)

    Small inductive currents are normally interrupted before a natural current zero, due to an instability resulting from an interaction between the arc(s) in the circuit breaker and the capacitance in the circuit. In the paper, a circuit is discussed which consists of two or more arcs in series, a capacitance and an inductance, when the parameters are different for the arcs. Analytical methods based ...
