Full title and description

IEC TR 61850-90-2:2016 — Communication networks and systems for power utility automation — Part 90-2: Using IEC 61850 for communication between substations and control centres. This Technical Report provides guidance and recommendations for information exchange between substations and control or maintenance centres and other system-level applications using the IEC 61850 family of standards.

Abstract

IEC TR 61850-90-2:2016 gives a comprehensive overview of considerations when applying IEC 61850 for communication between substations and higher-level control/maintenance centres. It defines use cases and communication requirements, describes usage of the IEC 61850 configuration language (SCL, IEC 61850‑6), gives guidelines for selection of communication services and architectures, outlines an engineering workflow, introduces a Proxy/Gateway concept, and covers Specific Communication Service Mapping (SCSM) aspects including MMS and sampled values over Ethernet.

Scope

This technical report addresses the use of IEC 61850 for communication between substations and control or maintenance centres or other system-level applications. It covers identification of use cases and communication requirements for substation-to-centre information exchange, use of SCL (IEC 61850‑6) for configuration and engineering, guidance on selecting communication services and architectures compatible with IEC 61850, engineering workflows, and SCSM details including MMS mappings and sampled-value transport considerations. Informative annexes include conformance statement guidance, SCL XML schema details and an example Substation SCD.

Key topics and requirements

• Definition of substation-to-control-centre use cases and associated communication requirements.
• Guidance on use of the SCL configuration language (IEC 61850‑6) for engineering and configuration exchange.
• Selection of communication services and network architectures compatible with IEC 61850 deployments.
• Specific Communication Service Mapping (SCSM) aspects, including MMS and sampled values (references to IEC 61850‑9‑2).
• Engineering workflow recommendations and the Proxy/Gateway concept for system-level integration.
• Informative annexes: protocol implementation conformance statements, SCL XML schema, and example SCD for substation-to-centre scenarios.

Typical use and users

Primary users are power utility engineers, substation automation designers, system integrators, control centre architects, product vendors (IED and gateway manufacturers), consultants and researchers working on power utility communications and substation-to-centre integration using IEC 61850. The report is used to plan architectures, select communication services, and guide engineering workflows for integration between substations and system-level applications.

FAQ

Q: What is this standard?

A: IEC TR 61850-90-2:2016 is a Technical Report in the IEC 61850 series that provides guidance on using IEC 61850 for communication between substations and control or maintenance centres (system-level applications). It is a non‑normative guidance document rather than a prescriptive normative part.

Q: What does it cover?

A: It covers use cases and communication requirements for substation-to-centre exchange, SCL usage for configuration, recommendations for communication services and architectures, engineering workflow and Proxy/Gateway concepts, plus SCSM details such as MMS and sampled-value mappings and informative annexes (conformance, SCL schema, example SCD).

Q: Who typically uses it?

A: Utilities, substation automation engineers, control-centre architects, system integrators, IED and gateway vendors, consultants and researchers focused on power system information exchange between substations and higher-level systems.

Q: Is it current or superseded?

A: The published edition is Edition 1.0 (25 February 2016). Catalogues and the IEC webstore list IEC TR 61850-90-2:2016 as the available Technical Report; no later edition or formal superseding document was identified in these publisher listings as of the available records. Users should check the IEC webstore or national bodies for any corrigenda or updates after 25 February 2016 if they require the absolute latest status.

Q: Is it part of a series?

A: Yes — it is part of the IEC 61850 family (Communication networks and systems for power utility automation) and specifically a Part 90‑series Technical Report offering application guidance related to system-level communications using IEC 61850.

Q: What are the key keywords?

A: IEC 61850, substation-to-centre communication, SCL, SCSM, MMS, sampled values, Proxy/Gateway, communication architectures, power utility automation, telecontrol.
