What is Edition 1 and Edition 2 of IEC 61850?

The first 14 parts of the standard SERIES IEC 61850 have been published between 2001 and 2004. These standards are often understood as IEC 61850 EDITION 1. Each of these parts and also the two parts IEC 61850-7-410 (Hydro Power) and IEC 61850-7-420 (DER) have been published tagged as EDITION 1. Example:

Several of these 16 published standards are now under revision (IEC calls this process maintenance). The revised document - once published - will be tagged EDITION 2, e.g., the EDITION 2 of part IEC 61850-6 has been published recently:

Additional parts, e.g., IEC 61850-7-4 or -7-3 are in the maintenance process and will be published in their EDITION 2 very soon.

BUT there will be not an EDITION 2 of the standard SERIES IEC 61850 per se!! Various parts (of the first 16 parts) will be revised and extended and then published tagged as EDITION 2.

New parts will be published with the tag EDITION 1, e.g., IEC 61850-80-1 (Guideline to exchanging information from a CDC-based data model using IEC 60870-5-101 or IEC 60870-5-104) - IEC/TS 61850-80-1, Edition 1.0, 2008-12.

All parts published after the first 14 parts that had been published by 2004 have either the tag Edition 2 or Edition 1 !!

If you are waiting for "Edition 2" what do you mean? I guess you mean the following:

• EDITION 2 of parts IEC 61850-6, -7-4, -7-3, -7-2, -7-1, -8-1, 9-2, 7-410, 7-420, etc. and
• EDITION 1 of the parts IEC 61850-80-1, 61850-90-1, -90-2, -90-3, -90-4, etc.

It is highly recommended to name the specific part when we talk about EDITION 2! Example: IEC 61850-6 EDITION 2.

Hope that helps!
