IEC TC 57 just Published Draft IEC TR 61850-7-5 ED1 - IEC 61850 Modelling Concepts

(57/2253/DTR - 33 pages) - voting closes 2020-09-11

Excerpt from the introduction:

"The standard IEC 61850 provides a very broad range of data models covering as much as possible all application functions in the range of power utility automation. The modelling both in the domains and between the domains show differences which may impact the interoperability. Therefore, some informative guideline is helpful to reach a common approach in application function modelling. A lot of basic functionality is based on the concept of IEC 61850 and, therefore, the same for all application domains. As result, a basic cross-domain part as Technical Report is useful. Domain specific issues are addressed in the Technical Reports 7-5xx (e.g. IEC TR 61850-7-500 for substation automation)."

DTR IEC 61850-7-500: How to use IEC 61850 for SAS

IEC TC 57 has published a Draft Technical Report (57/1817/DTR; 84 pages) with guidelines on how to apply IEC 61850 for substation automation:

Communication networks and systems for power utility automation –
Part 7-500: Basic information and communication structure – Use of logical nodes for modeling application functions and related concepts and guidelines for substations

This is a document that you MUST read when you are involved in substation automation.

This Technical Report of IEC 61850 describes the use of the information model for devices and functions of IEC 61850 in applications in substation automation systems but it may be used as informative input also 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. ...
Part 7-5 describes in examples the use of logical nodes for modeling application functions and related concepts and guidelines in general independently from any application domain respectively valid for all application domains in the electric power system (substation automation, distributed energy resources, hydro power, wind power, etc.). This part 7-500 describes in examples the use of logical nodes for application functions in substation automation including also line protection between substations. It implies also some tutorial material where helpful. But it is recommended to read parts IEC 61850-5 and IEC 61850-7-1 in conjunction with IEC 61850-7-3 and IEC 61850-7-2 first.
