Implementation of a RealTime Expert System for a Restoration Guide in a Dispatching Center

This paper describes a real-time expert system for a restoration guide which will be practically used in a dispatching center to evaluate the performance of the knowledge base system.

The system configuration is decentralized by workstations and one of them is attached to SCADA computer in order to get on- and off-line information on the current state of power system.

A restoration guide of this system has two operation modes. One is on-line guide mode, which gives operator an appropriate restoration plan and restorative procedures by using the knowledge, base of expertise and heuristics on power system restoration.

The other is off-line simulation mode, which is useful for knowledge engineer to verify the validity of the acquired knowledge.

Implementation issues of this system such as system function, knowledge acquisition, knowledge representation, interface of SCADA system and man-machine interface are discussed. Some execution results from the on-line guide mode are provided to demonstrate capability and efficiency of this system.
