Fuzzy Expert System-based Transmission Line Fault Diagnosis

The paper studies HV transmit electricity line fault diagnosis. Traditional fault diagnosis method of transmit electricity line can't be adapt to power system modernization. Therefore, it is of great importance to determine the exact fault location when fault happens. The paper brings forward a method of expert system.The paper analyzes HV transmit electricity line characteristic and based on the theory and method of fault diagnosis by applying theory of artificial intelligent, database and fuzzy theory, and brings forward a way of developing a fault diagnosis expert system based on fuzzy theory. It also gives out the frame of the system. In the implement of system, we use membership function to mirror faults fuzzy and fuzzy concern, relational database to describe knowledge and rules, and perform ruled-based inference...
