摘　　要：超导故障限流器可以在限流的同时实现控制非故障线路电压跌落的目的。分析了超导故障限流器的动作会不会影响系统中原有继电保护装置的正常运行,以及如何与保护装置配合动作2个问题。对超导故障限流器会不会使原有系统的电压电流波形产生畸变作出了分析。为了验证分析的正确性,使用电力系统仿真软件PSCAD对其进行仿真,得出一些有益的结论。The superconducting fault current limiter （SFCL） can limit current and realize to control the voltage dip in non-faulted line. Two problems were analyzed including the influence of SFCL movement on the normal operation of original protection installation in system, and coordination movement of protection device. It was analyzed that SFCL can make the distortion of voltage current waveform in original system or not. To verify the correctness of the analysis, power system software PSCAD was used to carry out the computer simulation, which reach some beneficial conclusions.
