The International Electrotechnical Commission (IEC) has released IEC TR 61850-7-500:2017 and it is now available on the IEC webstore. This technical report describes communication networks and systems for power utility automation, including use of logical nodes for modeling application functions and related concepts and guidelines for substations.
Description: “IEC TR 61850-7-500:2017 describes the use of the information model for devices and functions of IEC 61850 in applications in substation automation systems, but it may also be used as informative input for the modeling of any other application domain. In particular, it describes the use of compatible logical node names and data objects names for communication between Intelligent Electronic Devices (IED) for use cases.
This includes the relationship between Logical Nodes and Data Objects for the given use cases. If needed for the understanding of the use cases, the application of services is also described informatively. If different options cannot be excluded they are also mentioned.”
