FOREWORD

The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies.
All users should ensure that they have the latest edition of this publication.
No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication.
Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a Technical Specification when

the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or
the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard.

Technical Specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards.

IEC 61850‑2, which is a technical specification, has been prepared by IEC technical committee 57: Power system management and associated information exchange.

This second edition cancels and replaces the first edition, published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

definition of new definitions used in the new edition of the IEC 61850 standard series (abstract data model for communication; application function; backward compatible; common data class; communication system; composition; configuration compatibility list; configured IED description CID; conformance; data object class; decomposition; documentation; domain; forward compatible; function-related naming; granularity; IED configuration tool; IED parameters; instantiated IED description IID; intelligent electronic device capability description ICD; language; local function; logical device; mandatory data attribute; mandatory data object; meta model; namespace; object reference; optional data attribute; optional data object; performance; power system; power utility automation system; PUAS installation; PUAS parameter set; PUAS product family; product-related naming; secondary system; semantic name; system configuration description SCD; system configuration language SCL; system configuration language implementation conformance statement SICS; system configuration language version; system master; system configuration tool SCT; system design specification; system extension description SED; system related test; system requirement specification; system specification description SSD; system specification tool; technical issued conformance test TICS; tool; virtualisation; extensible mark-up language schema XSD);
updating of existing definitions to the new domain power utility automation of the IEC 61850 standard series and to provide homogeneity (abstract communication service interface ACSI; bay; client; data; data attribute; data object; device; distributed function; engineering tools; expandability; factory acceptance test FAT; flexibility; function; gateway; generic object-oriented system event GOOSE; generic system event model; IED parameter set; information model; instance; intelligent electronic device IED; interchangeability; logical connection; logical node; logical system; manufacturer; merging unit; model implementation conformance statement MICS; physical connection; physical device; physical system; piece of information for communication PICOM; process level functions; process related station level functions; protocol; protocol implementation conformance statement PICS; protocol implementation extra information for testing PIXIT; redundancy; scalability; server; site acceptance test SAT; specific communication service mapping SCSM; station level functions; supporting tools; system; system integrator; system life cycle; system parameters; system test; test equipment; type test);
removal of deprecated definitions (logical device class; generic system state event; substation automation system);
provision of clarifications and corrections to the first edition of IEC 61850‑2.
The text of this Technical Specification is based on the following documents:

Full information on the voting for the approval of this Technical Specification can be found in the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

IEC 61850 consists of the following parts, under the general title Communication networks and systems for power utility automation.

The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to the specific publication. At this date, the publication will be

transformed into an International standard,
reconfirmed,
withdrawn,
replaced by a revised edition, or
amended.

A bilingual version of this publication may be issued at a later date.

1 Scope

This part of IEC 61850, which is a Technical Specification, applies to power utility automation systems (PUAS). It defines the communication between intelligent electronic devices (IEDs) in the power utility automation system and the related system requirements.

This document contains the glossary of specific terminology and definitions used in the context of Power Utility Automation Systems within the various parts of the standard.

This document is, by its nature, a living part since new definitions and abbreviations will be created continuously in the standard documents that are being written inside the IEC related to IEC 61850.
