Application of IEC61850-80-1 in Peer-to-Peer Communication between Feeder Terminal Units

摘要

The trend towards using IEC61850 standards in feeder terminal unit (FTU) design is inexorable, but at present in China, IEC60870-5-104 is mostly used in distribution automatic system (DAS) information exchange. Thus it can be seen that IEC61850 standard will coexist with IEC60870-5 standard for a long time. IEC61850-80-1 provides the method of exchanging information from IEC61850 CDC-based data model using IEC60870-5-101 or IEC60870-5-104. This paper makes a brief analysis on the structure of DAS based on IEC61850, proposes the information model of FTU in accordance to IEC61850 and maps the information model to IEC60870-5-104 using IEC61850-80-1, which takes the advantage of IEC60870-5-104's excellent real-time performance to realize peer-to-peer communication between FTUs.
