摘　　要：柔性直流换流阀在出厂前,均需开展等效运行试验以保证其工程运行可靠性。而研制更高电压等级、更大容量的柔性直流换流阀,需要有合适的等效试验方法支撑。首先追溯了直流输电技术的发展进程,分析了开展柔性直流换流阀等效运行试验方法研究的重要意义。其次探讨了运行试验遵循的等效性原则,分析了柔直阀运行试验内容及方法在常规直流阀试验上的借鉴及发展。然后,在此基础上总结了国内外对柔直阀运行试验装置的研究成果,根据关键性指标的对比,对等效运行试验方法的优化方向及关键技术进行了展望。In the factory,routine tests of VSC(Voltage Source Converter)valves should be carried out to ensure the operation reliability of the VSC-HVDC(Voltage Source Converter Based High Voltage Direct Current)system.However,the VSC valves with higher voltage and larger capacity requires suitable equivalent test methods.Firstly,this paper traces the process of the DC(Direct Current)transmission technology and analyzes the significance of the research on the equivalent operation tests of the VSC valves.Next,the equivalent principle of tests is explored,and the reference and development of the LCC-HVDC(Line Commutate Converter Based High Voltage Direct Current)tests are illustrated.Finally,on the basis,the researches on the equivalent test equipment of the VSC valves at home and abroad are summerized.Through the comparison of the key indicators,the optimization direction and key technologies of the equivalent operation test methods are prospected.
