    The power quality experienced by electricity supply customers is dependent upon the design and operation of the power network and the reliability of the plant and equipment. Power quality is extensively affected by power system faults and how efficiently these are dealt with by the protection and control equipment. Voltage dips are one of the most prevalent events on the utility power system which... View full abstract»

    The development of cogeneration power plants following the deregulation of the electricity supply industry in New Zealand is reviewed. The consequential growth was due to the introduction of independent power producers in the market to build new generating plants, mainly cogeneration and combined cycle to compete with state-owned electricity producers. Recent experience of constructing different s... View full abstract»

    In mid February of 1998, the Auckland Central Business District suffered a power failure that left it with a minimal supply of power for three weeks and shortages and restrictions for another month or more. By the beginning of April, power supplies were sufficient-but still at risk from a single failure. An article in the June 1998 PEJ described the causes and sequence of events of the failure. Th...

    This tutorial describes some typical applications of artificial neural networks (ANNs) in power systems. It is the third in a series of three articles which, through a consideration of real problems, illustrates some of the practical aspects of ANN design in terms of architecture, training data requirements, selection of input features and learning algorithms. The paper discusses short term load f... View full abstract»
