Intelligent Fault Diagnosis Technology of Power Plant Relay Protection Equipment
Relay protection equipment is an important guarantee for the safe and stable operation of power system,and the application of its fault diagnosis technology is of great significance to improve the reliability of power grid.This paper introduces the operation principle and composition of relay protection equipment,and analyzes the common fault types,including misoperation fault,refusing action fault,insulation fault and mechanical fault.Aiming at these faults,this paper puts forward a variety of intelligent diagnosis methods,including using deep information mining technology to diagnose maloperation faults,integrating mechanism knowledge and machine learning method to diagnose refusing operation faults,designing expert diagnosis system to deal with insulation faults,and applying predictive maintenance decision-making technology to solve mechanical faults,aiming at improving the accuracy and efficiency of fault diagnosis,thus improving the reliability and safety of power system.
