L'IEC 62271-3:2015 s'applique aux appareillages à haute tension pour tous les niveaux de tension assignée supérieurs à 1 kV et à leurs assemblages et spécifie l'équipement destiné à la communication numérique avec d'autres parties du système d'automatisation de poste électrique et son impact sur les essais. Cet équipement de communication numérique, remplaçant le traditionnel câblage cuivre parallèle, peut être intégré dans l'appareillage à haute tension et dans ses assemblages ou peut être un équipement externe destiné à assurer la conformité des appareillages existants et de leurs assemblages avec les normes de la série IEC 61850. Cette deuxième édition annule et remplace la première édition, parue en 2006. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) une mise à jour de la ou des dernières éditions de la série IEC 61850; (par exemple l'Annexe B "Noeuds logiques pour les capteurs et la surveillance" de l'édition 1 a été supprimée car ces noeuds logiques sont désormais couverts par la norme IEC 61850-7-4:2010)
b) une mise à jour des références normatives;
c) la plage de tension minimale à laquelle se réfère la présente norme a été modifiée de 72,5 kV à plus de 1 kV;
d) la description des essais de qualification et des essais de conformité est devenue plus spécifique;
e) la nouvelle Annexe C (informative) donne un exemple d'essai de type de qualification;
f) le 6.2.3 "Systèmes de transmission" et les paragraphes correspondants ont été remplacés par l'IEC TR 61850-90-4:2013;
g) le type de connecteur pour fibres optiques LC devient le seul type recommandé de connecteur pour fibres optiques conformément à l'IEC TR 61850-90-4:2013;
h) les plaques signalétiques électroniques ont été redéfinies comme une extension du noeud logique XCBR et du noeud logique XSWI avec des objets de données, reflétant les informations supplémentaires exigées relatives à la plaque signalétique.

1) 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.

2) 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.

3) 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.

4) 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.

5) 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.

6) All users should ensure that they have the latest edition of this publication.

7) 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.

8) 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.

9) 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.

b) an update of normative references;
---------------------- Page: 7 ----------------------
– 6 – IEC 62271-3:2015 © IEC 2015

c) the minimum voltage range this standard refers to, was changed from 72,5 kV to above

1 kV;

d) the description of performance tests and conformance tests became more specific;

e) the new – informative – Annex C gives an example for performance type testing;

f) 6.2.3 “transmission systems” as well as appropriate subclauses have been superseded by

standard IEC TR 61850-90-4:2013;

g) fibre optical connector type LC becomes only recommended type of fibre optic connector

in accordance with IEC TR 61850-90-4:2013;

h) electronic nameplates have been redefined as extension of LN XCBR and LN XSWI with

data objects, reflecting required additional name plate information.

NOTE A new common data class Visible String Description (VSD) will be added to the IEC 61850-7-3 to support

these new data objects.

This standard has the status of a product family standard and may be used as a normative

reference in a dedicated product standard for highvoltage switchgear and controlgear.

The text of this standard is based on the following documents:
FDIS Report on voting
17C/617/FDIS 17C/623/RVD

Full information on the voting for the approval of this standard can be found in the report on

INTRODUCTION
0.1 General

This standard is a product family standard for high-voltage switchgear and controlgear and

assemblies thereof. It provides an application of the horizontal standard series IEC 61850

which details layered power utility communication architecture, in the world of high-voltage

switchgear and controlgear.

By providing tutorial material such as examples and explanations, it also gives an access for

switchgear experts to concepts and methods applied in the IEC 61850 series.

Compared to switchgear equipment, digital communication technology is subject to ongoing

changes which are expected to continue in the future. Profound experience with electronics

integrated directly into switchgear has yet to be gathered on a broader basis, as this type of

equipment is not widely spread in the industry and a change of metabolism has not yet

occurred.

This situation is taken into account in this standard by setting an appropriate validity date and

by specifying several options to most of the communication-related requirements, such as

connectors or fibres.
0.2 Position of this standard in relation to the IEC 61850 series

The IEC 61850 series is a horizontal standard intended to be used for communication and

systems in the power utility. The most important parts of this series define:
1) information models for the power utility automation system.

These information models include both the models of the switchgear (like circuit-breakers

and disconnectors) and other process equipment (like instrument transformers), and the

models of the power utility automation system (like protection relays);

2) the communication between intelligent electronic devices (IEDs) of the power utility

automation system;

3) a configuration language used to describe the configuration aspects of the power utility

automation system;

4) conformance testing of the communication interfaces of the IEDs of the power utility

automation system including their data models.

Typically, IEDs like bay level controllers interface to switchgear. In that case, the data models

of the switchgear are implemented in these devices. However, this is not the only realization.

In the case where electronics are integrated direct into switchgear, the above-mentioned data

models should be implemented within the switchgear and the switchgear supports a
communication interface.

IEC 61850, being a horizontal standard series, leaves many options open in order to support

present and future requirements of all sizes of power utility automation system at all voltage

levels.

HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Part 3: Digital interfaces based on IEC 61850
1 Scope

This part of IEC 62271 is applicable to high-voltage switchgear and controlgear for all rated

voltage levels above 1 kV and assemblies thereof and specifies equipment for digital

communication with other parts of the power utility automation and its impact on testing. This

equipment for digital communication, replacing metal parallel wiring, can be integrated into

the high-voltage switchgear, controlgear, and assemblies thereof, or can be external

equipment in order to provide compliance for existing switchgear and controlgear and

assemblies thereof with the standards of the IEC 61850 series.

This International Standard is a product standard based on the IEC 61850 series. It deals with

all relevant aspects of switchgear and controlgear, and assemblies thereof with a serial

communication interface according to the IEC 61850 series. In particular it defines:

a) a selection of the information models from the IEC 61850 series that are supported by

such switchgear and controlgear, and assemblies thereof;

b) conformance classes for the set of communication services that are supported by the

switchgear and controlgear, and assemblies thereof;

c) modifications and extensions to type and routine tests of switchgear and controlgear, and

assemblies thereof that are required due to the serial communication interface.

The standard specifies the requirements for digital communication equipment used within

high-voltage switchgear, controlgear, and assemblies thereof, as well as the relevant testing

requirements.

The relevant switchgear standards of the IEC 62271 series are applicable in general, with the

additional specifications described in this standard.

NOTE 1 This standard intends to promote interoperability of communication interfaces. Interchangeability is

outside the scope of this standard, as there is no requirement for it. Interchangeability is also outside the scope of

the IEC 61850 series.

NOTE 2 For an introduction to power utility automation communication and the related terms, definitions and

models, refer to IEC 61850-1 which provides an overview of the objectives and requirements of the IEC 61850

series in general. IEC 61850-7-1 provides an overview of modelling techniques.
2 Normative references
