    The optimization of electric power generation and transmission in real time, known as automatic generation control (AGC), is normally implemented through the application of a sophisticated real-time computer system known as an energy management system (EMS). A decision by Pacific Gas and Electric Co. to install an EMS is used to illustrate the factors that necessitate such an approach. The operati... View full abstract»

    The use of high voltages to measure insulating materials and spacings is discussed. Techniques for the generation and measurement of high test voltages are examined. Types of high-voltage tests are described. The procedures fall into three basic categories: those devised to test materials, those devised to test apparatus, and those devised to evaluate the deterioration of insulation in service.< View full abstract»

    The economic performance, and environmental advantages that are responsible for the growing use of high-voltage DC (HVDC) power transmission are examined. To gain the advantages of a DC system, measures must be taken to properly integrate the DC and AC systems. The various interactions between two systems, which need to be evaluated, are described. These are reactive power support, dynamic overvol... View full abstract»

    A comprehensive look at power sources is offered. The renewable sources covered are solar energy, wind energy, geothermal energy, ocean thermal energy conversion, tidal power, and energy from ocean waves. Also discussed are alternate nonrenewable sources, namely, fuel cell power plants, nuclear fusion, and magnetohydrodynamics.<> View full abstract»

    The types of reliability considerations and the deterministic criteria currently used by most utilities for electric transmission reliability planning are outlined. The complex process of weighing outage costs against prevention costs in this approach is discussed. A probabilistic approach increasingly being adopted by electric utilities is described that allows costs and benefits of reliability t... View full abstract»

    The possible health hazards of low-level, power line frequency (50/60 Hz) electric and magnetic fields are considered. The historical background to this concern is briefly discussed. The types of studies being carried out and the results so far are summarized. It is concluded that while the scientific evidence on field effects is inconclusive, inferences of health effects justify further evaluatio... View full abstract»

  • Power lines: broadcasting's problem child

    Publication Year: 1988, Page(s):38 - 40
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (431 KB)

    Scattering and reradiation of radio signals by power lines, which causes undesired changes in broadcast antenna patterns, is discussed, using as an example station CHFA, serving Edmonton, Alberta. The computer model of a power line is presented, and it is shown how it can be used to detune the line, i.e. to suppress the current flow that is induced on the towers by the broadcast antenna which redu...
