31、chnical 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 Specificatio
32、ns, 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,
33、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 decisi
34、ons 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 interna
35、tional 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 orde
36、r 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 clea
37、rly 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 b
38、odies. 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, prope
39、rty 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 t
40、his 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
41、or all such patent rights. International Standard IEC 62590 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. This standard is based on EN 50328. The text of this standard is based on the following documents: FDIS Report on voting 9/1387/FDIS 9/1411/RVD F
42、ull 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. 6 62590 IEC:2010 The committee has decided that the contents of this publication wil
43、l 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. 62590 IEC:2010 7 INTRODUCTION Semiconducto
44、r converters for traction power supply differ from other converters for industrial use due to special electrical service conditions and due to the large range of load variation and the peculiar characteristics of the load. For these reasons IEC 60146-1-1 does not fully cover the requirements of rail
45、way applications and the decision was taken to have a specific standard for this use. Converter transformers for fixed installations of railway applications are covered by EN 50329. Harmonization of the rated values and tests of the whole converter group are covered by IEC 62589. 8 62590 IEC:2010 RA
46、ILWAY APPLICATIONS FIXED INSTALLATIONS ELECTRONIC POWER CONVERTERS FOR SUBSTATIONS 1 Scope This International Standard specifies the requirements for the performance of all fixed installations electronic power converters, using controllable and/or non-controllable electronic valves, intended for tra
47、ction power supply. The devices can be controlled by means of current, voltage or light. Non-bistable devices are assumed to be operated in the switched mode. This Standard applies to fixed installations of following electric traction systems: railways, guided mass transport systems such as: tramway
48、s, light rail systems, elevated and underground railways, mountain railways, trolleybusses. This Standard does not apply to cranes, transportable platforms and similar transportation equipment on rails, suspended cable cars, funicular railways. This Standard applies to diode rectifiers, controlled r
49、ectifiers, inverters and frequency converters. The equipment covered in this Standard is the converter itself. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) a
