An expert system for power systems maintenance

When power equipment fails, maintenance personnel have traditionally had to investigate and repair the equipment by using information supplied by supervision and control systems, specified in manuals, or gained through personal experience. To enable maintenance personnel to respond more quickly and accurately, the authors have developed an expert system (called ALICE-ES), that provides diagnostic expert know-how and emergency procedures arranged in knowledge bases. These knowledge bases can be used to visually display optimal resolution procedures. ALICE-ES also has a friendly human-machine interface, offering features like full mouse-click operation and help functions. This paper describes the configuration, the functions, and the system technology of ALICE-ES.<>
