    Wind energy exploitation is likely to be economically viable in many cases where electricity is generated using diesel fuel. The economics of such cases are examined using statistical methods. The aim is to determine the optimum level of wind power capacity that should be installed in a diesel supplied network on the basis of known facts about the network and about the generation and local wind ac...

  • Decoupling techniques applied to the design of a controller for an unregulated synchronous machine

    Publication Year: 1985, Page(s):277 - 280

    Decoupling techniques using state variable feedback are proposed for the design of a controller for a 2-input 2-output linear time-invariant multivariable model of an unregulated synchronous machine supplying power to an infinite grid, to accomplish single-input single-output decoupling and pole assignment, and thus enhance the dynamic (stability) characteristics of the resulting closed-loop syste...

  • Decomposed load-flow algorithm suitable for parallel processor implementation

    Publication Year: 1985, Page(s):281 - 284

    The paper presents a new method for load-flow analysis which is particularly appropriate for very large power systems. The objective has been to reduce the computation time for the analysis of a given system by tearing the network into a number of independent subsystems. The subsystem programs may be executed in parallel, resulting in a considerable time saving for on-line system control. The main... View full abstract»

  • Performance comparison of two exact outage simulation techniques

    Publication Year: 1985, Page(s):285 - 293

    The paper compares the performance of two exact load-flow and outage simulation techniques. The second-order Newton-Raphson technique is described first, where the voltages are represented in rectangular co-ordinates. Then the power-flow solution by the method of reduction and restoration is described. Both methods use the complete Taylor series expansion of the nodal equations but the latter is d...

  • A frequency-dependent transmission line model for electromagnetic transient studies

    Publication Year: 1985, Page(s):294 - 297
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (475 KB)

    A simple lumped-parameter model for the frequency-dependent transmission line is presented in this paper. The transients due to sequential energisation of a 345 kV transmission system have been computed with the proposed line model. The computed results show satisfactory agreement with field measurements. View full abstract»

  • Lightning performance criteria for electric power systems

    Publication Year: 1985, Page(s):298 - 306
    Cited by:  Papers (1)

    In the paper the author has examined the parameters which influence the number of lightning strikes terminating on electric power lines and, having made assumptions, has proceeded accordingly to apply them to a variety of transmission and distributions lines worldwide, thanks to the co-operation of some 30 electric supply authorities who, in answer to a questionnaire, supplied basic parameters and...

  • Modelling of saturated reactor compensator for system studies

    Publication Year: 1985, Page(s):307 - 311
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (439 KB)

    A method of modelling multi-limbed saturated reactors under dynamic and steady-state conditions, allowing for both the electrical interconnection of the windings and the core construction, is presented. A selection of results from a digital computer program based on the simulation are given, illustrating the dynamic response of the reactor model to parameter changes under system energisation. The ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (892 KB)

    As part of a comprehensive study of transformer behaviour, the factors which control the aging processes in transformer paper have been reviewed experimentally. Three different types of paper have been used: 60/40 manilla/wood, all-wood and thermally upgraded paper. Aging has been done in vitro under oil in atmospheres of nitrogen and air with controlled water contents. The aging temperatures were... View full abstract»
