    Publication Year: 1986, Page(s):373 - 376
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (549 KB)

    Power utilities are required to provide electrical energy to consumers as economically and reliably as possible. For most developing power systems, the problems arise at the 11 kV distribution level and the reliability of the network can be increased by increased investment with a consequent reduction in outage costs. The paper reviews methods for evaluating outage costs due to system interruption... View full abstract»

  • Medium-term forecasts of half-hourly system demand: development of an interactive demand estimation coefficient model

    Publication Year: 1986, Page(s):393 - 396
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (446 KB)

    This paper describes a model which predicts half-hourly system demand for representative days in the year using detailed load research data and electricity sales forecasts. The approach is to construct daily load curves for individual consumer categories, expressed in the form of demand estimation coefficients, and aggregate these into a total system demand curve by applying the appropriate sales ...

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1259 KB)

    A representative set of electric power distribution system planning models published in the literature has been reviewed. The models have been classified according to their characteristics, from the point of view of stages of the plan and overall time span; the methods of treating distribution feeders and/or substations in terms of cost representation, location and sizing problems; radiality and v...

  • Overhead distribution lines¿some reflections on design

    Publication Year: 1986, Page(s):409 - 424
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2760 KB)

    While existing regulations regarding the design of overhead lines have served well the electricity supply industry, recent happenings, when many networks suffered damage in Europe, have highlighted the need for a critical review of design practices. It is argued that, provided some statistical data on meteorological phenomena are available, attempts could be made to design overhead lines to suit s... View full abstract»

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (710 KB)

    This paper describes a user oriented computer program for power cable load capability (ampacity) calculations developed in Ontario Hydro. The program is based on the IEC Standard, Publication 287 and Neher-McGrath procedure and is implemented in a user friendly form for desktop computer. Power cable load capabilities for a wide range of conditions can be calculated with a minimum of input data usi... View full abstract»

    The paper reviews the need for overhead line switching equipment and its use in developing countries for the control of long radial feeders into remote districts. The requirements for pole-mounted equipment and relaying characteristics are discussed showing the need for sensitive earth fault discrimination, particularly to detect broken conductors in regions of high earth resistance.

  • Method of protecting distribution transformers connected solidly to an urban 11 kV network

    Publication Year: 1986, Page(s):441 - 444
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (782 KB)

    Ground mounted 11 kV/433 V distribution transformers have a high level of reliability; approximately 100 fail in the UK per year out of a total of 160 000. The provision of protection by the traditional means of fuses or circuit-breakers at the transformer appears to be an unnecessary expense. Consequently consideration has been given to the solid connection of transformers to the network. The maj... View full abstract»

  • Economic design of a 50 kVA distribution transformer. Part 1: The use of liquids of low flammability

    Publication Year: 1986, Page(s):445 - 450
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (774 KB)

    Many alternative designs of transformer meet the rating, voltage and impedance specifications of a customer. However, only one design will give minimum total cost defined as purchase price plus capitalisations of core and winding losses. In this study the cost of materials, labour and electrical losses are carefully computed and the purchase price and total cost of alternative designs are plotted ... View full abstract»

  • Economic design of a 50 kVA distribution transformer. Part 2: Effect of different core steels and loss capitalisations

    Publication Year: 1986, Page(s):451 - 456

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (573 KB)

    A range of 50 kVA transformers has been designed by computer for minimum total cost, defined as the purchase price plus the capitalised cost of losses. Two core steels are compared, Unisil 28M4 and Nippon 23 ZDKH, and in each case four loss capitalisations have been taken. For optimal designs based on available prices for materials and labour, a lower total cost is found for 23ZDKH except when the... View full abstract»
