Implementation of a real-time expert system for a restoration guide in a dispatching center

The authors describe a real-time expert system for a restoration guide which is intended for use in a dispatching center to evaluate the performance of a knowledge-based system. The system configuration is decentralized by workstations, one of which is attached to a SCADA (supervisory control and data acquisition) computer to obtain on and offline information on the current state of the power system. The restoration guide of this system has two operation modes. One is the online guide mode, which gives the operator an appropriate restoration plan and restoration procedures by using the knowledge base of expertise and heuristics on power system restoration. The other is the offline simulation mode which can be used by the knowledge engineer to verify the validity of the acquired knowledge. Implementation issues of this system, such as system function, knowledge acquisition, knowledge representations, the interface of the SCADA system, and the man-machine interface, are discussed. Some execution results from the online guide mode are provided to demonstrate the capability and efficiency of this system.<
