This part of IEC 61850 provides a comprehensive overview on the different aspects that need to be considered while using IEC 61850 for information exchange between substations. In particular, this technical report

  • defines use cases that require an information exchange between substations;

  • describes the communication requirements;

  • gives guidelines for the communication services and communication architecture to be used;

  • defines data as a prerequisite for interoperable applications;

  • does not define implementations which guarantee interoperability between different IEDs;

  • describes the usage and enhancements of the configuration language SCL.
