29、MISSION _ STATIC VAR COMPENSATORS (SVC) TESTING OF THYRISTOR VALVES 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 internati

30、onal 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 re

31、ferred 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

32、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 intern

33、ational 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 reasona

34、ble 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 P

35、ublications 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 conformi

36、ty. 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

37、. 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

38、 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 ap

39、plication 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. This consolidated version of IEC 61954 consists of the secon

40、d edition (2011) documents 22F/217/CDV and 22F/231A/RVC and its amendment 1 (2013) documents 22F/274/CDV and 22F/287A/RVC. It bears the edition number 2.1. The technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. A vertical line i

41、n the margin shows where the base publication has been modified by amendment 1. Additions and deletions are displayed in red, with deletions being struck through. 6 61954 IEC:2011+A1:2013 International Standard IEC 61954 has been prepared by subcommittee 22F: Power electronics for electrical transmi

42、ssion and distribution systems, of IEC technical committee 22: Power electronics. This edition includes the following significant technical changes with respect to the previous edition: a) Definitions of terms “thyristor level”, “valve section”, “valve base electronics” and “”redundant thyristor lev

43、els” have been changed for clarification. b) Conditions of testing thyristor valve sections instead of a complete thyristor valve have been defined. c) The requirement has been added that if, following a type test, one thyristor level has become short-circuited, then the failed level shall be restor

44、ed and this type test repeated. d) The time period of increasing the initial test voltage from 50 % to 100 % duringtype a.c. dielectric tests on TSC, TCR or TSR valves has been set equal to approximately 10 s. e) The duration of test voltage Uts2 duringtype a.c.-d.c. dielectric tests between TSC val

45、ve terminals and earth as well as the duration of test voltage Utvv2 during dielectric tests between TSC valves (for MVU only) has been changed from 30 min to 3 h. f) The reference on the number of pulses per minute of the periodic partial discharge recorded during a.c.-d.c. dielectric tests on TSC

46、valves and exceeding the permissible level has been deleted. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of the base publication and its amendment will remain unchanged until the stability date indicated on the IEC

47、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. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours wh

48、ich are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 61954 IEC:2011+A1:2013 7 STATIC VAR COMPENSATORS (SVC) TESTING OF THYRISTOR VALVES 1 Scope This International Standard defines type, production and option

49、al tests on thyristor valves used in thyristor controlled reactors (TCR), thyristor switched reactors (TSR) and thyristor switched capacitors (TSC) forming part of static VAR compensators (SVC) for power system applications. The requirements of the standard apply both to single valve units (one phase) and to multiple valve units (several phases). Clauses 4 to 7 detail the type tests, i.e. tests which are carried out to verify that
