What's New with IEC 61850: WG 10 Meeting in Stockholm

by Joe Stevens | Mar 11, 2015
Joel Greene represented Triangle MicroWorks at the Working Group 10 Meeting held in Stockholm in February. Working Group 10 is part of IEC Technical Committee 57 and oversees the definition of the IEC 61850 standard. During the week long session, several task forces addressed many different technical areas including the upcoming Edition 2.1 amendment, conformance testing, Logical Modelling, Application Profiles, UML Model, and ENTSO-E feedback.

Working Group 10 is working toward a draft of the Edition 2.1 amendment which will be reviewed later this year. The new draft will include updates to Parts 6, 7-1, 7-2, 7-3, 7-4, 8-1 and 9-2. Joel Greene is the editor for Section 7-2 of the Edition 2.1 amendment. Section 7-2 addresses Abstract Communication Services Interface (ACSI) which defines the modeling classes and related services for IEC 61850 including Control Blocks, Data Sets, GOOSE, Sampled Values, and Controls.

Here is a summary of other WG 10 initiatives from Stockholm:

  • Testing Technical Reports - there was a discussion on the testing of Technical Reports, especially 90-4 and 90-5. It was agreed that Technical Reports cannot be officially tested before they are incorporated into one of the International Standard documents.

  • Logical Modelling Task Force - this task force is working towards a standard definition for representing device logic in the System Configuration Language (SCL).

  • Basic Application Profile Task Force - this task force is defining what information can be included in IEC 61850 device profiles. The device profile could include information about IEC 61850 capabilities (services supported, Object Model, Control Blocks) or other characteristics of the device.

  • UML Model - WG 10 is working towards an agreement with the IEC for open usage of "code components" of the IEC 61850 standard, which will be generated from a master data model stored in UML. Parts 6, 7-2, 7-3, and 7-4 will include UML modeling in Edition 2.1 which is scheduled to be published this year. The UML model will help to visualize the information model data structures and verify consistency and accuracy. The UML model will also be machine readable so that XML can be generated directly from the UML version of the standard. This will help automate the implementation of the standard by IEC 61850 tools.

  • Feedback from ENTSO-E - the European Network of Transmission System Operators for Electricity (ENTSO-E) presented feedback on the ENTSO-E engineering process including discussions on backward compatibility of Edition 1 and 2 along with the need for machine readable device comparisons. In an effort to improve multi-vendor interoperability across IEC 61850 devices, ENTSO-E has produced lots of useful feedback for Working Group 10 to address.
