Part 90-1: Use of IEC 61850 for the communication between substations

Another 12 Parts are under development. Some of these are almost ready for publication in 2012.

Several of the above listed documents have the tag “Edition 2”, some have still the tag “Edition 1” and are in the maintenance process.

A complete list comprises all 30 parts: Title, publication, stability date, … see excerpt in the table below (the complete table can be downloaded – see below):image

The table indicates as well how many tissues have been posted at the tissue database for most parts tagged edition 1 and tagged edition 2.

Please note that there is NO “IEC 61850 Edition 2” !! There are only Editions of the PARTS!!

If you want to know the current status of the standard series IEC 61850 (January 2012) you have to check the status of ALL documents at early January 2012 (red vertical line in the figure below):

Some of the documents are still Edition 1 (yellow) others are Edition 2 (green). 10 of the 18 parts are still EDITION 1 !! 8 parts are EDITION 2. The other 12 parts under development will be published as EDITION 1.

The 6 parts that are usually understood as “IEC 61850 Edition 2” are:

-6 Ed2
-7-1 Ed2
-7-2 Ed2
-7-3 Ed2
-7-4 Ed2
-8-1 Ed2

This is NOT an official name!
