A Fuzzy Expert System for the Integrated Fault Diagnosis

송전계통과 변전소의 통합 고장진단을 위한 퍼지 전문가 시스템

This paper presents a practical fuzzy expert system to diagnose various faults occurred in local power systems. This integrated system can diagnose all faults occurred in a transmission network and substations. In this paper. the fuzzy reasoning of the diagnostic process is discussed in detail. The discrimination of false operations and non-operations of protective devices as well as the fault identification scheme are also analyzed together with the fuzzy inference process.
