Description (English):

IEC 61850-7-1:2011 introduces the modelling methods, communication principles, and information models that are used in the various parts of the IEC 61850-7 series. The purpose is to provide - from a conceptual point of view - assistance to understand the basic modelling concepts and description methods for: - substation-specific information models for power utility automation systems, - device functions used for power utility automation purposes, and - communication systems to provide interoperability within power utility facilities. Compared to the first edition, this second edition introduces: - the model for statistical and historical statistical data, - the concepts of proxies, gateways, LD hierarchy and LN inputs, - the model for time synchronisation, - the concepts behind different testing facilities, - the extended logging function. It also clarifies certain items.

Abstract

Overview - IEC 61850-7-1:2011 (Principles and models)

IEC 61850-7-1 defines the basic communication structure, modelling methods and principles used across the IEC 61850 family for power utility automation. It provides a conceptual framework to describe:

substation-specific information models,
device functions for power utility automation, and
communication systems that enable interoperability within substations and power facilities.

Edition 2 (consolidated with Amend.1) extends the first edition by introducing models for statistical and historical data, time synchronisation, proxies/gateways and logical device (LD) hierarchy, logical node (LN) inputs, testing facilities, and an extended logging function - all aimed at improving device modelling and reliable communications.

Key topics and technical requirements

Information modelling: Logical nodes (LNs), common data classes and composition rules that define semantic data for protection, control and monitoring.
Device and logical device models: Structure, nameplate data, LD hierarchy and proxies/gateways for virtualisation and device integration.
Communication principles and services: Abstract Communication Service Interface (ACSI), client-server interactions, and mapping guidance to concrete protocols.
Data types and namespaces: Specification of namespaces, versioning rules and extension policies to maintain compatibility across standards and implementations.
Time synchronisation: Conceptual model for time alignment of measurements and events.
Statistical & historical data modelling: Models for statistical and historical statistical information used in trending, reporting and diagnostics.
Testing, logging and engineering: Concepts for test signals, simulation, extended logging and use of Substation Configuration Language (SCL) for configuration and engineering.
Annexes with practical mapping: Includes mapping examples (e.g., IEC 61850-8-1), GOOSE/SMV subscription configuration and engineering workflows.

Applications and practical value

Provides the conceptual backbone for designing interoperable substation automation systems and integrating Intelligent Electronic Devices (IEDs).
Guides OEMs and system integrators on how to model device functions, data semantics and communication services for protection, control and monitoring.
Supports utilities in establishing consistent engineering practices, SCL-based configuration, reliable time-synchronised measurements, logging and testing strategies.
Enables vendors to implement compatible client-server and event-based messaging (e.g., GOOSE/SMV mappings) while preserving semantics across products.

Power utilities and transmission/distribution operators
IED and substation equipment manufacturers (OEMs)
System integrators and engineering contractors
Test laboratories and certification bodies
Standards committees and product designers focused on substation interoperability
