摘　　要：厦门柔性直流输电工程首次采用真双极接线方式,缺乏相关调试经验和试验方案。本文根据该工程特点提出大功率试验方法,包括双极热运行、阀冷冗余、一极紧急停运等试验内容。通过大功率试验可验证设备性能是否符合有关标准要求,并测量谐波含量、换流站效率等参数。试验方法和结果可为厦门柔性直流输电工程运行参数调整和模块化多电平换流器优化设计提供依据,同时也可为其他工程调试提供可借鉴的经验。The bipolar mode was firstly adopted in Xiamen HVDC flexible transmission project, and it was lack of relevant debugging experience and experimental method. According to the characteristics of Xiamen project, the high power experimental method was proposed, including bipolar thermal performance test, cooling system redundance test and emergency shutdown test. It is verified that the equipments are in compliance with the requirements by high power experiment, and the parameters such as harmonic and loss are measured during the test. Experimental method and results can provide basis for adjusting the operating parameters of the HVDC flexible project and optimizing the design of the converter, and can also provide experience for the construction of other HVDC flexible project.
