摘　　要：以一种电流补偿型故障限流器为对象,研究了其对电力系统暂态稳定性的影响。在概述该型限流设备的拓扑结构及工作原理的基础上,计及不同的故障工况探讨了其对系统暂态稳定性的强化机制。进而利用MATLAB/SIMULINK电磁暂态仿真程序,构建了涵盖故障限流器的单机无穷大系统详细模型,通过模拟多种场景下的系统运行特性,检验了理论研究的有效性。结果表明,此型限流器的引入可明显抑制发电机功角振荡、延长故障切除时间、提高系统应对短路冲击的强壮性。This paper studies the influence of a current compensation type fault current limiter（FCL） on power system transient stability. This suggested FCL＇s structure principle is presented in brief, and its action mechanism to the transient stability is theoretically discussed in accordance with different fault conditions. Further, based on MATLAB/SIMULINK, a detailed model of a single-machine infinite system integrated with the FCL is built, and the system＇s operational charac- teristics are imitated to verify the theoretical analysis＇s effectiveness. The demonstrated results show that, applying the FCL can obviously suppress the power-angle oscillation, increase the fault clearance time and enhance the system＇s robustness against the short-circuit fault.
