Thyristor valves for high voltage direct current (HVDC) power transmission - Part 1: Electrical testing

This part of IEC 60700 applies to thyristor valves with metal oxide surge arresters directly
connected between the valve terminals, for use in a line commutated converter for high voltage
d.c. power transmission or as part of a back-to-back link. It is restricted to electrical type and
production tests.
The tests specified in this standard are based on air insulated valves. For other types of valves,
the test requirements and acceptance criteria can be agreed.

Thyristorventile für Hochspannungsgleichstrom-Energieübertragung (HGÜ) - Teil 1: Elektrische Prüfung

Valves à thyristors pour le transport d'énergie en courant continu à haute tension (CCHT) - Partie 1: Essais électriques

IEC 60700-1:2015 est disponible sous forme de IEC 60700-1:2015 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
IEC 60700-1:2015 s'applique aux valves à thyristors  équipées  de parafoudres à oxyde métallique directement connectés entre les bornes des valves, qui sont destinées à être utilisées au niveau d'un convertisseur commuté     par  le réseau pour  le  transport d'énergie en courant continu à haute tension ou dans une liaison dos      à dos. Elle est limitée aux  essais  de type électriques et de série.  Les essais spécifiés dans  la présente norme sont basés  sur   des valves isolées par l'air. Pour d'autres types de valves, les exigences d'essai et les critères  d'acceptation   peuvent faire l'objet d'un accord. Cette édition inclut les modifications techniques majeures suivantes par rapport à    l'édition précédente.
a) Les définitions des termes "niveaux de thyristors redondants", "niveau de thyristor", "section de valve" ont été modifiées dans un souci de clarification.
b) Des notes ont été ajoutées aux exigences des essais diélectriques sur support de valve sous tension continue, UVM, spécifiant qu'avant de répéter l'essai avec la polarité opposée, l'objet d'essai peut être court-circuité et mis à la terre pendant plusieurs heures. La même procédure peut être suivie à l'issue de l'essai sous tension continue.
c) Le Tableau 1 sur les défauts de niveaux de thyristors autorisés au cours des essais de type a été complété.
d) La méthode alternative pour les essais diélectriques UVM a été ajoutée.
e) Il a été spécifié que les essais de série peuvent inclure des essais individuels de série ainsi que des essais sur prélèvement.
f) Il a été ajouté dans les exigences pour les essais d'allumage et d'extinction périodiques qu'un facteur d'échelle pour les essais doit être appliqué lors des essais sur les sections de valve.

Tiristorski ventili (elektronke) za visokonapetostni enosmerni prenos (HVDC) električne energije - 1. del: Električno preskušanje

Ta del standarda IEC 60700 velja za tiristorske elektronke s kovinskooksidnimi prenapetostnimi odvodniki, ki so neposredno povezani med priključki elektronke, za uporabo v vodovno komutiranih pretvornikih za visokonapetostni enosmerni prenos moči ali kot del povezave zaporedne vrste. Omejen je na električno vrsto in proizvodne preskuse.
Preskusi, določeni v tem standardu, temeljijo na zračno izoliranih elektronkah. Za druge vrste elektronk se lahko sklene dogovor glede zahtev preskusa in meril sprejemljivosti.

THYRISTOR VALVES FOR HIGH VOLTAGE DIRECT
CURRENT (HVDC) POWER TRANSMISSION –

Part 1: Electrical testing

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 60700-1 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 second edition cancels and replaces the first edition published in 1998, its Amendment
1:2003 and its Amendment 2: 2008. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition.
a) Definitions of terms “redundant thyristor levels”, “thyristor level”, “valve section” have been
changed for clarification.
b) The notes were added to test requirements of dielectric d.c. voltage tests for valve support,
MVU, valve, specifying that before repeating the test with opposite polarity, the tested

---------------------- Page: 11 ----------------------

SIST EN 60700-1:2015
– 6 – IEC 60700-1:2015 © IEC 2015
object may be short-circuited and earthed for several hours. The same procedure may be
followed at the end of the d.c. voltage test.
c) Table 1 on thyristor level faults permitted during type tests was supplemented.
d) The alternative MVU dielectric test method was added.
e) It was specified that production tests may include routine tests as well as sample tests.
f) It was added into test requirements for periodic firing and extinction tests that a scaling
factor for tests shall be applied when testing with valve sections.
The text of this standard is based on the following documents:
CDV Report on voting
22F/341/CDV 22F/351A/RVC

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.
A list of all parts in the IEC 60700 series, published under the general title Thyristor valves for
high voltage direct current (HVDC) power transmission, can be found on the IEC website.
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
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
