IEC 61850 Tissue Database is Crucial for Improving the Quality of IEC 61850

The Tissue (technical issues) Database is one of the most important means to improve the quality of the standard series IEC 61850.
When IEC published the first parts of the series in 2004 the editors used a Word document to keep track of technical issues reported to the key experts and the results of their discussions. NettedAutomation developed the Tissue Database to offer a public tool to support the standardization and quality assurance process.

The following parts have an entry in the Database:



We just added an entry to part 90-2 (Substation to Control Center communication).
Please note that the almost 1,500 entries play a crucial role in the latest parts published and in the UCAIUG testing specification. Excerpt of IEC 61850-6 Amendment 1 to Edition 2:



This list has 50+ entries referring to the Tissue Database.

Products that claim conformance with IEC 61850 have to be accompanied by the so-called "TICS" Technical Issues Conformance Statement. This is a list that describes which Technical Issues have been implemented in a specific product. It is quite important to understand, that a specific Technical Issue that has an impact on client and server (publisher and subscriber) has to be implemented on both sides!!

The test labs for IEC 61850 have to test Technical Issues - when required by the testcase. The UCAIUG maintains a list of all "green" Tissues that are integral part of UCAIUG Testing requirements.

If you have an issue with IEC 61850 I recommend to check the Database and search for the topic you are looking for. Maybe your concern has already been solved ... you find a lot of good discussions in many tissues.

NetteAutomation will continue to offer the Tissue Database for the next parts to be published, e.g., Edition 2.1 of the core documents.

Enjoy the Database.

18	IEC/TR 61850-90-1	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):

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!

Most parts published by January 2013 are still marked EDITION 1 !!

How can you feed back your experience with IEC 61850?

The many parts of the standards series IEC 61850 published require some kind of maintenance. In order to collect, discuss, solve, and document the feedback from the market, IEC TC 57 WG 10 has set-up a database: The Technical Issues database or just: the Tissues database.

More and more experts from utilities feed their experience back to the standardization groups. An example is the latest post of today:

In case you find any tissue in the published standards search the Tissue database first and post a new tissue if your tissue has not yet been posted.
