Research on Fault Diagnosis Method of Electric Energy Metering Equipment Based on Expert System

The realization of the full coverage of the smart meter and the metering automation terminal across the entire network brings great challenges to the operation and maintenance of the field. Aiming at the long-term problems of on-site failure operation and maintenance of the electric energy metering equipment, this paper combines the metering and collecting of failure types to analyse the main causes of equipment failure, based on the field topology structure for fault reasoning, and designs fault diagnosis and fault knowledge base as the core module for fault diagnosis. The expert system has been proved by practice that this method can effectively diagnose and solve the failure problem of the energy metering equipment, which is beneficial to realize the intelligentization of on-site fault diagnosis and improve the on-site maintenance efficiency of the energy metering equipment, and has practical reference value.
