标准摘要
[中文适用范围]： 本国际标准适用于高压直流（HVDC）设施的系统测试，这些设施由发送端和接收端组成，每个端都连接到交流系统。本标准中规定的测试基于双向单极和双极高压直流（HVDC）设施，这些设施由发送端和接收端组成，每个端都连接到交流系统。测试要求和验收标准应针对背靠背设施达成一致，而多端系统和电压源转换器不包括在本标准中。对于单极HVDC设施，本标准适用，但不包括双极测试。对于特定项目声称的特殊功能或性能，应根据技术规范要求添加本标准中未包括的额外测试项目。本标准仅作为高压直流（HVDC）设施系统测试的指南。本标准为潜在用户提供了关于如何规划调试活动的指导。指南中描述的测试可能不适用于所有项目，但代表了一系列应考虑的可能测试。因此，项目组织最好基于本标准建立个别测试计划，并提前为每个特定项目在相关组织（如用户、供应商、制造商、运营商、采购方等）之间分配各种任务/测试的责任。 [外文原描述]： IEC 61975:2010+AMD1:2016+AMD2:2022 applies to system tests for high-voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each connected to an a.c. system. The tests specified in this standard are based on bidirectional and bipolar high-voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each connected to an a.c. system. The test requirements and acceptance criteria should be agreed for back-to-back installations, while multi-terminal systems and voltage sourced converters are not included in this standard. For monopolar HVDC installations, the standard applies except for bipolar tests. This standard only serves as a guideline to system tests for high-voltage direct current (HVDC) installations. The standard gives potential users guidance, regarding how to plan commissioning activities. The tests described in the guide may not be applicable to all projects, but represent a range of possible tests which should be considered. This edition cancels and replaces IEC/PAS 61975 published jointly in 2004 by IEC and CIGRÉ. It constitutes a technical revision incorporating engineering experience.
