Study of Communication Gateway Based on IEC61850 Protocol

IEC61850 communication protocol is seamless standard of future power system and substation. Remote communication method based on IEC61850 was studied, and it has put forward a new communication gateway interface model, view of abstract communication service interface and special communication service mapping technology, and it has mapped three communication protocol stacks. It has designed three layer modules of IEC61850 real-time database system, IEC60870-5-101/104 protocol conversion server and MMS resolver based on multi-threading technology. At last, it has designed realization process of communication gateway.
