IEC 61850

  • IEC 61850 is the most recent standard for communication networks and systems in substations. Its scope of definitions greatly exceeds that of the preceding standard IEC 60870-5-101. IEC 61850 comprises these individual standards:

    • IEC 61850-1, 61850-2
      Introduction and overview / Glossary
    • IEC 61850-3
      General requirements
    • IEC 61850-4
      System and project management
    • IEC 61850-5
      Communication requirements for functions and device models
    • IEC 61850-6
      Configuration description language for communication in electrical substations related to IEDs
    • IEC 61850-7-1
      Basic communication structure for substation and feeder equipment - Principles and models
    • IEC 61850-7-2
      Basic communication structure for substation and feeder equipment - Abstract communication service interface (ACSI)
    • IEC 61850-7-3
      Basic communication structure for substation and feeder equipment - Common data classes
    • IEC 61850-7-4
      Basic communication structure for substation and feeder equipment - Compatible logical node classes and data classes
    • IEC 61850-8-1
      Specific Communication Service Mapping (SCSM) - Mapping to MMS (ISO 9506-1 and ISO 9506-2) and to ISO/IEC 8802-3
    • IEC 61850-9-1
      Specific Communication Service Mapping (SCSM) - Sampled values over serial unidirectional multidrop point-to-point link
    • IEC 61850-9-2
      Specific Communication Service Mapping (SCSM) - Sampled values over ISO/IEC 8802-3
    • IEC 61850-10
      Conformance testing

    IEC 61850 is not limited to the transmission format, but also defines a complete data model. It also introduces an XML-based language (Substation Configuration description Language -  SCL) offering a vendor-independent method of describing devices and their configurations.

    IEC 61850 is supplemented by branch-specific data models (e.g. IEC 61400-25), in which the basic protocol principles are maintained.
    The standard IEC 61400-25 (communications for monitoring and control of wind power plants) is also implemented in the protocol stack IEC 61850, Client.
    The mapping is complying with part 4 of the norm (IEC 61400-25 annex C: IEC 61400 per Manufacturing Message Specification (MMS) according to IEC 61850-8-1).
