| 摘 要： | 特高压直流输电方式具有送电容量大、送电距离远、输电线路损耗小等优点，在我国今后的能源流动中具有不可替代的地位。文章在分析特高压直流输电系统换相失败机理的基础上，利用PSCAD／EMTDC仿真工具，研究了基于CIGRE直流输电标准测试模型建立的特高压直流输电仿真系统换流母线侧发生不同类型交流故障时对换相失败的影响，从而为系统规划及安全稳定措施的制定提供了一定的理论依据。

| Abstract: | UHVDC transmission system is with the characteristics of large capacity, long distance and low losses among others. It will have an indispensable role in energy development in China. Based on the analysis of commutation failure of UHVDC, the article studies the effect of the commutation failure when the commutation buses have different kinds of AC faults on the base of CIGRE Benchmark Model, with the Simulation of PSCAD/EMTDC. It provides a theory basis for as- suming strategies about the power system planning and stability. |
