IEC TC 57 Just Published Additional Code Components for IEC 61850

IEC TC 57 has published five additional code components document as listed in the figure:

These documents are very helpful ... they provide the main parts of the corresponding information models.

IEC 61850 Edition 2.1 of Core Documents Published

The other day IEC TC 57 has published five more parts as Edition 2.1 - it took several years to get there! But finally it was successful.

I would call these Edition 2.1 documents simply the real Edition 2 documents.

First of all, what does Edition 2.1 mean?

The original edition 2 documents needed some corrections and updates. All crucial corrections et cetera have been documented in the Tissue Database (https://iec61850.tissue-db.com/default.mspx). The solutions provided on the Tissue Database have been used as input to the standardization process and led to amendments number 1 of the corresponding parts. These amendments have been commented and balloted officially by the members of TC 57. These amendments 1 are now the official documents that are amending the edition 2 documents (both are valid for the next years).

In order to make the "edition 2.1" more readable and understandable, there are other documents available: The consolidated parts 2.1 ... comprising the "old" stuff, the fixes and the extensions.




Consolidated Version of part 7-2: https://webstore.iec.ch/publication/66525 :



So: This consolidated version consists of the second edition (2010) and its amendment 1 (2020). Therefore, no need to order the amendment in addition to this publication.

Note: The first Tissues for edition 2.1 have already be posted, e.g., for part 7-2 Edition 2.1:



The following Previews for edition 2.1 consolidated versions are available:

Preview IEC 61850-6 Edition 2.1
Preview IEC 61850-7-2 Edition 2.1

Preview IEC 61850-8-1 Edition 2.1
Preview IEC 61850-9-2 Edition 2.1

Note: The name spaces (code components) for the edition 2.1 parts will be available soon - I hope:

How Many and Which Information Models are defined in IEC 61850?

I guess you have heard that IEC 61850 defines a lot of Information Models. Yes, You are right.

The models are managed exclusively by the corresponding working groups with the Enterprise Architect UML Tool (the UML data base is for internal use only). The model version:

UML model of 61850 (wg10built6-wg18built3-wg17built5-jwg25built2-tc17built1-tc38built1.eap)

comprises the following number of Logical Node Classes, Data Objects (Attributes), Enumerations and Abbreviations:



An excerpt from the UML modes looks like this:



The UML Model is the single source data base that is used for the extensions and maintenance of the model, as well as the generation of Word or PDF documents ... The PDF documents are sold by IEC and other organizations.

You may complain that the standards are not for free ... hmm ... BUT look: You can download the various Code Components for free.

Example of Enumeration:


Example of excerpt of LN Class MMU:

To my understanding you can model many required information generated and consumed by a huge number of applications in almost all application domains of automation in the electrical system and beyond.

As the above example of MMXU shows, you can use this LN Class wherever you have 3 phase AC system!! In a building heating system for the electrical values of a compressor or a fan or a pump or ... the blue sky is the limit for the applications.

Click HERE to learn about crucial details discussing the LN Class MMXU and how it can be applied ... you may have never expected this comprehensiveness of the MMXU.

Note that the 3 phase system was first (more than 100 years ago) - then we have put a facade in front of the measurement function which exposes the measurements as data objects of the class MMXU. The application has driven the class - not vice versa.

The current edition 2.1 models defined in IEC 61850-7-3 and 7-3 are listed in the contents tables of the preview documents. The following Preview documents (free access) for models of the edition 2.1 consolidated versions are available:

Preview IEC 61850-7-3 Edition 2.1
Preview IEC 61850-7-4 Edition 2.1

Example of 7-4 from the preview:

IEC Offers Code Components for IEC 61850 and other standards

One of the most crucial benefits of IEC 61850 information models is the availability of code components - the possibility to get a computer processable document that contains the formal definition of a model, e.g., the measurements of a three phase system.

Handling of Code Components in IEC Standards
Including Copyright Licensing

Handling of Code Components v8.0 2019-08-29

This document sets out the process and rules to be used by IEC groups (TCs, SCs, PCs, WGs, SyCs, …) and experts in charge of editing IEC documents to ensure a proper handling of copyright licensing of code components included in IEC deliverables. It also defines the technical and process requirements to consider to optionally offer a free access to certain code component(s) through the IEC web site. At the current time this document only applies to IEC TC57

WOW -- IEC 61850 Models Publically Available for Download

After long time, IEC has accepted to provide free online access to the IEC 61850 Models!!

Congratulation!

Excerpt from 57/2023/INF (2018-07-13):

"With IEC 61850-7-7, a machine processable format for the distribution of IEC 61850 data models has been defined. Based on that, in the future, all IEC 61850 models will be as well available in this format as namespace files (NSD files).
The namespace files are code components, that are intended to be directly processed by a computer. The purchase of the associated IEC standard carries a copyright license for the purchaser to sell software containing Code Components from this standard to end users either directly or via distributors, subject to IEC software licensing conditions, which can be found at: http://www.iec.ch/CCv1. ..."

Data and Communications Security: IEC TC 57 Just Published IEC 62351-7

IEC TC 57 just published IEC 62351-7:2017:
Power systems management and associated information exchange - Data and communications security - Part 7: Network and System Management (NSM) data object models

IEC 62351-7:2017 defines network and system management (NSM) data object models that are specific to power system operations. These NSM data objects will be used to monitor the health of networks and systems, to detect possible security intrusions, and to manage the performance and reliability of the information infrastructure. The goal is to define a set of abstract objects that will allow the remote monitoring of the health and condition of IEDs (Intelligent Electronic Devices), RTUs (Remote Terminal Units), DERs (Distributed Energy Resources) systems and other systems that are important to power system operations. This new edition constitutes a technical revision and includes the following significant technical changes with respect to IEC TS 62351-7 (2010): NSM object data model reviewed and enriched; UML model adopted for NSM objects description; SNMP protocol MIBs translation included as Code Components.
The Code Components included in this IEC standard are also available as electronic machine readable file.

The standard series IEC 61850 will also come with Code Components when the various 7-x parts will be published as International Standard. This will ease the development and maintenance of engineering and configuration tools ... tremendously.
Check HERE for Code Components ... coming later in 2017 or 2018 ...
