摘　　要：加装超导限流器是目前最理想的限流措施之一,超导限流器接入电网后,改变了系统固有参数,影响电力系统暂态稳定性能。利用PSCAD/EMTDC仿真软件,搭建了单机无穷大系统及3机9节点系统,对不同场景下系统发生三相短路故障时的发电机功角摇摆曲线进行仿真分析。通过对比系统安装SFCL和未安装SFCL时功角的摇摆曲线,得出了SFCL对暂态稳定性的影响规律。The installation of superconducting fault current limiter （SFCL） is an ideal means of fault-current limita- tion; however, the grid-connected SFCL resuhs in the intrinsic system parameter changes, inevitably affecting the system transient stability. Therefore, a single machine to infinite system and a three-machine 9-node system are con- structed on the EMTDC/PSCAD platform, then used to simulate a series of swing curves of generator power-angle in the case of three-phase short-circuit fault occurring under different situations in power system. By comparing the re- sults between the simulations with and without SFCLs, the influence of resistive SFCL on transient stability of power system is revealed.
