An Expert System for On-Line Diagnosis of System Faults and Emergency Conrol to Prevent a Blackout

Abstract In this paper an expert system for on-line diagnosis of system faults and emergency control to prevent a blackout is introduced. Fuzzy set logic is used to diagnose different types of faults. Counter measures for each type of system fault are suggested during emergency conditions. It has been tested on a 5 machine, 23 node test system, for all types of system faults the simulation results are correct. This expert system will be used as a guide to the operator during emergency conditions.
