General

The contents of Distribution Automation (DA) vary between different countries, regions, even between different utilities in the same country. DA may cover HV/MV substations, MV networks, LV networks, distributed energy resources, as well as demand sides. This part of IEC 61850, which is a technical report, provides basic aspects that need to be considered when using IEC 61850 for information exchange between systems and components to support Distribution Automation applications, within MV network automation, as presented in Annex B.

In particular, this document:

• defines use cases for typical DA applications that require information exchange between two or more components/systems

• provides modelling of components commonly used in DA applications

• proposes new logical nodes and the extensions to the existing logical nodes that can be used in typical DA applications.

• provides guidelines for the communication architecture and services to be used in DA applications

• provides configuration methods for IEDs to be used in DA systems.

Its content also results from the merge of the preparatory work exposed in IEC TR 62689-100 - Current and voltage sensors or detectors, to be used for fault passage indication purposes - Part 100: Requirements and proposals for the IEC 61850 series data model extensions to support fault passage indicators applications.

Namespace information

The parameters which identify this new release of this namespace are:

• Namespace Version: 2018

• Namespace Revision: A

• UML model file which reflects this namespace edition: wg10uml02v20draft20- wg18uml02v11b-wg17uml02v22-jwg25uml02v04c-tc17umlv0-tc38umlv0.eap, UML model version WG10UML02v20draft20 • Namespace release date: 2018-05-20

• Namespace name: "(Tr)IEC61850-90-6:2018A"

The name space "(Tr)IEC61850-90-6:2018A" is considered as "transitional" since the models are expected to be included in IEC 61850-7-4xx Edition 2. Potential extensions/modifications may happen if/when the models are moved to the International Standard status.
