Abstract

The communication is the key of power system relay protection and fault information managing system. The communicationinterface requirement and implementation scheme is proposed in this paper, which based on the IEC103 standard and TCP/IP protocol, and this scheme can meet the demand of interface between master station and substation. The message specification between the master station and substationis also studied in detail. According to the requirement of communication reliabilityin master system, anefficient mechanismis proposed,it can improve the communication reliabilityand performance.
