Description of PD IEC TR 61850-90-6:2018 2020

1.1 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.

1.2 Namespace name and version

This new subclause is mandatory for any IEC 61850 namespace (as defined by IEC 61850‑7‑1:2011).

Table 60 shows all attributes of (Tr)IEC61850‑90‑6:2018B namespace.

1.3 Namespace Code Component distribution

The Code Components are in light and full version:

• The full version is named : IEC_TR_61850-90-6.NSD.2018B.Full.It contains definition of the whole data model defined in this standard with the documentation associated and access is restricted to purchaser of this part

• The light version is named : IEC_TR_61850-90-6.NSD.2018B.Light. It doesn't contain any documentations but contains the whole data model as per full version, and this light version is freely accessible on the IEC website for download at : /2, but the usage remains under the licensing conditions.

The Code Components for IEC 61850 data models are formated in compliance with the NSD format defined by the standard IEC 61850‑7‑7. Each Code Component is a ZIP package containing :

• the electronic representation of the Code Component itself (possibly multiple files),

• the grammar files (XSD) enabling to check the consistency of the associated files against the defined version of NSD, but as well against the IEC 61850 flexibility rules in case of private extensions

• a file describing the content of the package (IECManifest.xml).

The IECManifest contains different sections giving information on:

• The copyright notice

• The identification of the code component

• The publication related to the code component

• The list of the electronic files which compose the code component

• An optional list of history files to track changes during the evolution process of the code component

The life cycle of a code component is not restricted to the life cycle of the related publication. The publication life cycle goes through two stages, Version (corresponding to an edition) and Revision (corresponding to an amendment). A third publication stage (Release) allows publication of Code Component in case of urgent fixes of InterOp Tissues, thus without need to publish an amendment. Consequently new release(s) of the Code Component may be released, which supersede(s) the previous release, and will be distributed through the IEC TC57 web site at: /2. The latest version/release of the document will be found by selecting the file named IEC_TR_61850-90-6.NSD.{VersionStateInfo}.Light with the filed VersionStateInfo of the highest value.
