AN INTELLIGENT TOOL FOR DISTRIBUTION SUBSTATIONS TROUBLESHOOTING AND MAINTENANCE SCHEDULING

The objective of this paper is to describe SUBES: a Rule-Based Expert System Approach for Distribution Substations Troubleshooting and Maintenance Scheduling. These complex decision tasks are nowdays performed by highly experienced engineers, whose knowledge can be expressed as a set of production rules. As inference mechanism for the knowledge processing, first order logic is natural. Therefore the system has been implemented in Turbo-Prolog. SUBES works interactively. A very user-friendly environment for the interaction between computer and end-user is achieved by a menu-driven dialog and a multi-window display. The modularity of the system quarantees easy updating. The system has been developed by the Electric Power Systems Laboratory of the National Technical University of Athens and can be used for educational and, as well, engineering purposes.
