直流输电用的电压源换流器（VSC）阀 - 电气测试
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.
IEC 62501:2024适用于自耦换流器阀，用于三相桥式电压源换流器（VSC）高压直流输电或作为回路链的一部分，并且适用于动态制动阀。它仅限于电气类型和生产测试。本文件可用作指导，用于测试用于能量存储系统（ESS）的高压VSC阀。本文件中指定的测试基于空气绝缘阀。测试要求和验收标准可用于指定其他类型阀的电气类型和生产测试的指导。本版包括以下与上一版相比的重大技术变化：
a）插入替代证据使用条件作为新表1;
b）阀支持直流电压测试的测试参数，7.3.2，和MVU直流电压测试，8.4.1，已更新;
c）阀端之间的交直流电压测试，第9款，进行了重组，并在9.4.2中添加了通过单独的交流和直流电压测试的替代测试;
d）例行测试程序中的局部放电测试已删除;
e）附录B中添加了有关阀组件容错能力的更多信息;
f）阀损耗的确定已添加为附录C。
