IEC 61850 extensions proposed by ENTSO-E

IEC TC 57 distributed a proposal from ENTSO-E to add some features to IEC 61850 (57/1771/DC).

Proposed new work items by ENTSO-E to introduce additional specification features of IEC 61850 based systems within SCL. Edition 2 of IEC 61850-4 was published in 2011. Edition 2 of IEC 61850-6 was published in 2009.

Ultimately, the proposal by the ENTSO-E statement and example of engineering process, aims to serve the market in order to reach the multi-vendor interoperability of systems in an efficient way.123

Crucial Topics are:

  • Input and data flow modelling / Virtual IED – Introduction of additional specification features of IEC 61850 based systems within SCL.
  • System engineering efficiency – Introduction of additional specification and configuration features of IEC 61850 based systems within SCL.
  • Communication Network Description – Introduction of additional specification and configuration features of IEC 61850 based systems within SCL.

Big utilities have already used SCL to specify the details they want vendors to implement.

The time where vendors could model the automation system the way they like it most seems to be over soon. Utilities start to understand that even interchangeability is the ultimate goal!

It all depends on the willingness to cooperate! [News on IEC 61850 and related Standards]
