摘　　要：配电网容量增大和非线性负荷的增加致使短路电流的增大、电能质量的变差,传统的固态短路限流器性能已满足不了电网运行的要求。提出了一种主要由限流电感与并联在电感两端的背靠背系统组成的新型短路限流器,分析了新型短路限流器的拓扑结构及其控制策略,通过搭建仿真模型进行仿真分析,证明该方法可以对电网中任意的短路故障进行操作,且可以改善电网的电能质量。The increasing capacity of distribution network and nonlinear load results in larger fault current limiter （FCL） and leads to poor power quality. Traditional FCL can＇t meet the demands, so a new FCL made up of the current-limiting inductor and the back-to-back system paralleled by the inductor is proposed. The topology and control strategy of the new FCL are analyzed. By constructing of simulation model, the method proves it can apply in any short circuit fault, improve power quality.
