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".
