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<\/p>\n
defines use cases that require an information exchange between substations;<\/p>\n<\/li>\n
describes the communication requirements;<\/p>\n<\/li>\n
gives guidelines for the communication services and communication architecture to be used;<\/p>\n<\/li>\n
defines data as a prerequisite for interoperable applications;<\/p>\n<\/li>\n
does not define implementations which guarantee interoperability between different IEDs;<\/p>\n<\/li>\n
describes the usage and enhancements of the configuration language SCL.<\/p>\n<\/li>\n<\/ul>\n
