IEC 61850 & IEC 61400-25 SCC Motivation: sustainable interoperability The standards IEC 61850 „Communication networks and systems for power utility automation“ and IEC 61400-25 „Communications for monitoring and c ontrol of wind power plants“ prov ide support for sustainable interopera- bility: Information Models, Information Exchange Methods, Protocol Mappings, and System Configu- ration Language (SCL) for Power Systems (Generation, Transmission, and Distribution for HV, MV, and LV, … ).

A LN prov ides a list of named data obj ects (DO). The LN “XCBR” represents a real “circuit bre aker” with the dat a object (DO) “Pos” (Position). IEC 61850-7-2 defines Information Exchange Methods, e.g., for the position (with Client/Server services, GOOSE, SMV). Data flow is specified by a SCL file (IEC 61850-6). 61850-6 SCL conf igurati on file Real devices in substation or wind turbines SCSM, e.g. 61850-8-1 or 9-2 ...
