摘　　要：UPFC集多种控制功能于一体,更具灵活性。利用PSCAD/EMTDC仿真软件建立了两端柔性交流输电的仿真模型,研究了单相接地故障与感应雷过电压故障。结果表明:当单相接地时,UPFC会动作产生补偿电压;感应雷过电压时,送端母线、受端母线和变流器阀两端都会出现严重的过电压。基于上述分析,为了保护重要的电力设备,最后给出了避雷器的配置方案。UPFC collects a variety of control functions in an organic whole and is more flexible. Based on PSCAD/EMTDC simulation software, the model of the flexible AC is established. Single-phase earth fault and induced lightning overvohage are studied. The results show that the UPFC will work and generate offset voltage under earth fault and the sending bus, the receiving end and converter valve will causes severe overvoltage when induced lightning overvohage appears. Based on the important power equipment, a configuration method of surge arrester is proposed in this paper.
