Application of Iec61850 in substation automation system

Combined with practical work, this paper introduces substation system architecture based on IEC61850 and application scheme of virtual server used in IEC61850 system; The key technologies such as IEC61850 conformance testing, technical characteristics of training system, KEMA UniCA 61850 protocol analysis tool, IEC61850 key technology, such as MMS communication protocol to with independent property rights, are introduced. Finally demonstration project of substation automation system conformed with IEC61850 is introduced and suggestions for interoperability and conformance testing are proposed.
