Communication networks and systems for power utility automation. Use of IEC 61850 for Distribution Automation Systems | Status: Current

1 Scope

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.
