This paper presents a new application of expert system techniques to the restoration of distribution systems. Primary feeders are typically radial in structure. To increase system reliability, neighboring feeders are connected through a normally open tie switch. When load zones on a feeder are interrupted due to a fault, system operators need to identify neighboring feeders and try to restore customers through the tie switches. To restore maximal number of zones, several steps are followed: group restoration, zone restoration and, if necessary, load transfer. Based on the methodology, an expert system is developed which can be utilized as an on-line aid to system operators in a distribution SCADA environment. The proposed expert system is implemented in Prolog. Implementation issues on knowledge representation, portability of the system, and computational efficiency are discussed. Several examples are used to illustrate capabilities of the proposed system.
