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

Voting closes 2017-02-17

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.

New Draft IEC TR 61850-7-500 Just Published - Typical Use Cases

IEC TC 57 has just published a very interesting document (75+ page Draft Report) - 57/1701/DC:
IEC TR 61850-7-500 – Use of logical nodes for modelling applications and related concepts and guidelines for substations

The draft provides examples and hints on how to use IEC 61850 for substation automation, protection and SCADA. Sample excerpt of content:

This document is crucial to understand use cases of the standard for substation applications.
Note that the examples given are showing just some possible applications. In practice there will be other use cases - depending on the philosophy of a specific utility. The use cases are not standardized!
In case a utility is looking for exchangeability of IEDs from different vendors, it has to specify the SCD file to a very high degree!
Recently I had a meeting with experts from a big transmission utility: They have reached a level of system specification in order to allow interoperability AND exchangeability of IEDs from multiple vendors! To get there: You need to request something more than just "IEC 61850".

First Draft on how to use IEC 61850 models in substations (IEC 61850-7-500)

IEC TC 57 has recently published a first Draft IEC TR 61850-7-500 – Use of logical nodes for modelling applications and related concepts and guidelines for substations (57/1371/DC). The document comprises almost 60 pages.

Comments are requested by 2013-07-12 at the latest.

The technical report is intended to provide guidelines and explanations, how the logical nodes defined in IEC 61850-7-4 shall be combined and used to model applications from substation automation domain.

A crucial goal is to show the most common application of Logical Nodes in
modelling simple and complex functions, to improve common understanding in modelling and data exchange, and finally to lead to implementations which keep at least interoperability.

For those people that are interested in process bus applications, it is highly recommended that you review that document!
