用于高压直流 (HVDC) 电力传输的电压源换流阀 (VSC) 电气测试

[中文适用范围]： 本国际标准适用于用于高压直流输电或作为背靠背连接部分的三相桥式电压源换流器（VSC）的自换相换流阀，以及动态制动阀。它仅限于电气类型和生产测试。 本标准的范围包括动态制动阀的电气类型和生产测试，这些阀可用于某些HVDC方案中的直流过电压限制。 本文件可用作测试用于能量存储系统（ESS）的高压VSC阀的指南。 本文件中规定的测试基于空气绝缘阀。对于其他类型的阀，测试要求和验收标准应由买方和供应商之间协商确定。测试要求和验收标准可用作指定其他类型阀的电气类型和生产测试的指南。 [外文原描述]： IEC 62501:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 62501:2024 edition 2.0 and the previous IEC 62501:2009+AMD1:2014+AMD2:2017 CSV edition 1.2. Furthermore, comments from IEC SC 22F experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 62501:2024 applies to self-commutated converter valves, for use in a three-phase bridge voltage sourced converter (VSC) for high voltage DC power transmission or as part of a back-to-back link, and to dynamic braking valves. It is restricted to electrical type and production tests. This document can be used as a guide for testing of high-voltage VSC valves used in energy storage systems (ESS). The tests specified in this document are based on air insulated valves. The test requirements and acceptance criteria can be used for guidance to specify the electrical type and production tests of other types of valves. This edition includes the following significant technical changes with respect to the previous edition: a) Conditions for use of evidence in lieu are inserted as a new Table 1; b) Test parameters for valve support DC voltage test, 7.3.2, and MVU DC voltage test, 8.4.1, updated; c) AC-DC voltage test between valve terminals, Clause 9, is restructured and alternative tests, by individual AC and DC voltage tests, added in 9.4.2; d) Partial discharge test in routine test program is removed; e) More information on valve component fault tolerance, Annex B, is added; f) Valve losses determination is added as Annex C.
