In order to improve the communication efficiency and stability of protection relay fault information system (hereinafter referred to as PRFIS), based on the analysis of current situation of PRFIS,this paper puts forward a method of online communication message analysis for PRFIS, via monitoring of communication messages between master station and slave station, analyzing the error of messages, obtaining the reason that causes the error, and raising the way to correct the error. After a period of trial operation, it has been found that the online communication message analysis system can find and analyze some errors of PRFIS, accordingly it improves the communication quality of PRFIS.
