IEC 61975:2010
(Main)High-voltage direct current (HVDC) installations - System tests
High-voltage direct current (HVDC) installations - System tests
IEC 61975:2010 applies to system tests for high-voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each connected to an a.c. system. The tests specified in this standard are based on bidirectional and bipolar high-voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each connected to an a.c. system. The test requirements and acceptance criteria should be agreed for back-to-back installations, while multi-terminal systems and voltage sourced converters are not included in this standard. For monopolar HVDC installations, the standard applies except for bipolar tests. This standard only serves as a guideline to system tests for high-voltage direct current (HVDC) installations. The standard gives potential users guidance, regarding how to plan commissioning activities. The tests described in the guide may not be applicable to all projects, but represent a range of possible tests which should be considered. This edition cancels and replaces IEC/PAS 61975 published jointly in 2004 by IEC and CIGRÉ. It constitutes a technical revision incorporating engineering experience.
Installations en courant continu à haute tension (CCHT) - Essais systèmes
La CEI 61975:2010 s'applique aux essais systèmes pour les installations en courant continu à haute tension (CCHT) qui se composent d'une borne d'émission et d'une borne de réception, chacune reliée à un système à courant alternatif. Les essais spécifiés dans la présente norme sont basés sur des installations en courant continu à haute tension (CCHT) bidirectionnelles et bipolaires qui se composent d'une borne d'émission et d'une borne de réception, chacune reliée à un système à courant alternatif. Il convient que les exigences d'essai et les critères d'acceptation soient convenus pour les installations en opposition, alors que les systèmes à bornes multiples et les convertisseurs à source de tension ne sont pas inclus dans la présente norme. Pour les installations CCHT monopolaires, la norme s'applique, excepté pour les essais bipolaires. La présente norme sert uniquement de lignes directrices des essais systèmes pour les installations en courant continu à haute tension (CCHT). La norme fournit des recommandations aux utilisateurs potentiels quant à la manière de planifier les activités de mise en service. Les essais décrits dans le guide ne peuvent être applicables à l'ensemble des projets, mais représentent une partie des essais possibles qu'il convient de prendre en considération. Cette première version de la CEI 61975 annule et remplace la CEI/PAS 61975 qui a été publiée conjointement en 2004 par la CEI et le CIGRE, dont elle constitue une révision technique combinée à une expérience en ingénierie.

FOREWORD
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.
International Standard IEC 61975 has been prepared by subcommittee 22F: Power electronics
for electrical transmission and distribution systems, of IEC technical committee 22: Power
electronic systems and equipment.
This first version of IEC 61975 cancels and replaces IEC/PAS 61975 published jointly in 2004
by IEC and CIGRÉ. It constitutes a technical revision incorporating engineering experience.
The text of this standard is based on the following documents:
FDIS Report on voting
22F/221/FDIS 22F/227/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
61975 © IEC:2010(E) – 5 –
The committee has decided that the contents of this publication will remain unchanged until the
stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to
the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version may be issued at a later date.
