This paper analyzes the basic principle and function of relay protection, summarizes the common fault types, and analyzes the fault analysis methods and treatment measures combined with actual cases. A method of fault tracking for relay protection devices is presented in this paper. Fault tracking means that after the failure of relay protection devices, the anomalies and warning informa-tion are obtained through data-mining technology, and then, the fault tracking algorithm is used. Relay fault diagnosis refers to the process of identifying and analyzing faults or abnormalities in protective relays. However, in actual operation, the relay protection device may cause failure due to hardware failure, software problems or external. For a long time, the fault diagnosis technology of relay protection consists of isolated cases and does not have a systematic method.
