Draft TR IEC 61850-90-6 for Distribution Automation Published

IEC TC 57 WG 17 just published the 277 page (!) draft TR 57/1929/DTR:

IEC 61850-90-6: Use of IEC 61850 for Distribution Automation Systems

Commenting period and ballot closes 2017-12-01.

This technical report provides basic aspects that need to be considered when using IEC 61850 for information exchange between systems and components within MV network automation. In particular, the report:

• 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.

Basic function for which models will be selected or defined cover:

• Fault Passage Indication and report
• FLISR (Fault Location, Isolation and Service Restoration)
• VVC (Voltage and Var Control)
• Anti-Islanding Protection Based on Communications
• Automatic Switch Transfer
• Monitoring Energy Flow
• Environment Situation Awareness

A Distribution Automation System (DAS) can have up to tens of thousands of IEDs spreading
over a wide area distribution network.

Multiple new Logical Node Classes and extensions for existing LNs are proposed:



This draft is very detailed and easy to read.
