IEC 61975:2010适用于高压直流（HVDC）装置的系统试验，该装置由一个发送端子和一个接收端子组成，每个端子都连接到交流系统。本标准中规定的试验基于双向和双极高压直流（HVDC）装置，该装置包括一个发送端子和一个接收端子，每个端子都连接到交流系统。应对背对背安装的测试要求和验收标准达成一致，而本标准不包括多端系统和电压源转换器。对于单极高压直流装置，该标准适用于双极试验。本标准仅作为高压直流（HVDC）装置系统测试的指南。该标准为潜在用户提供了有关如何计划调试活动的指导。本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。 本版本取消并取代IEC和CIGRé于2004年联合发布的IEC/PAS 61975。它是结合工程经验的技术修订。

IEC 61975:2010 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.
