    It seems that whenever you pick up a newspaper or turn on the evening news there is something new about the Internet and the World-Wide Web (WWW or Web). When you attend a technical conference, speakers encourage you to look at their home pages for more information. Sales representatives provide you with a URL for more detailed technical specifications on their products. For some, the idea of surf... View full abstract»

    It is a general perception that power subjects are concerned with the study of high-voltage, high-current components, such as large machines and high voltage transmission lines. But that is a narrow-minded view. The subject of modern protection, for example, is interdisciplinary by nature. This article describes courses and personal computer (PC) based facilities that are available at the Universi... View full abstract»

    Dynamics recording devices (DRDs) that monitor and record the transient or dynamic response of power systems are installed across power systems. DRDs that have been installed in the last decade have increasingly used digital computer implementation-these include digital relays, digital fault recorders, integrated electronic controls for substation automation and many digitally implemented controls...

    When faults occur on major transmission lines, the bulk power system is immediately exposed to potentially costly outages. During peak loading conditions, when line availability is most critical, a lengthy outage can be detrimental to system operations. In an age of open access and retail wheeling, power exchanges are bound by contract, and any unnecessary delay of energy restoration compromises a... View full abstract»

    Early detection of abnormalities in electric motors helps to avoid expensive failures. Motor current signature analysis (MCSA) implemented in a computer-based motor monitor can contribute to such condition-based maintenance functions. Such a system may also detect an abnormality in the process as well as the motor. Extensive online monitoring of the motors can lead to greater plant availability, e... View full abstract»

    Traditionally, the linear analysis of a power system is performed by first computing a state space model, followed by the application of a suitable analysis method. However, the applicability of this approach is restricted by several practical limitations: typical power systems are represented by very large state matrices that require specialized large-scale eigen analysis programs; the program wh...

    The European Union funds the thematic network for intelligent forecasting systems (IFS) by the Brite-EuRam program. This program is in the field of industrial and material technologies. The network brings together industry and universities all over Europe for cooperation in forecasting systems of refineries and power systems. This article describes the general tasks, objectives, and worksteps asso... View full abstract»
