Communication

Application of IEC 61850 for Protection Communication between Substations

Initially, the scope of IEC 61850 communication was clearly restricted to the substation. But with the proliferation of IEC 61850 in real installations, it became apparent that there are obvious applications where exchange of information in IEC 61850 format would be also beneficial between substations. Thus, the comprehensive communication and service concept of IEC 61850 could be uniformly applied over the whole protection and automation system without explicit distinction between local communication and communication to remote substations. IEC TC57 WG10 has established a task force for this topic already back in 2006 which worked on the technical report IEC 61850-90-1.
