A restoration aid expert system for distribution substations

This paper presents a practical restoration aid expert system for 154kV distribution substations. The proposed expert system has a topology based simple structure and it utilizes basic rules suggested by Korea electric power company including heuristic rules, topology identification rules and searching rules to gen switching sequence for feasible restoration process. In thi er, general system structure as well as rules and data sentations are discussed. The expert system is realized using HP9000 workstation. X-window and Motif shell is used for user friendly GUL It has been tested in a practical sub-control center as a part of the intelligent fault diagnosis and restoration aid system to assist decision making of SCADA operators.
