摘　　要：研究了在配电系统中引入限流器后的系统行为。假设二线短路故障分别发生在电源侧母线出口和负荷馈线末端，在三点分别设置了限流器，利用ＥＭＴＰ软件对限流器的故障电流抑制效果进行了模拟。结果表明限流器的引入具有明显的限流效果，并可改善因故障引起的母线电压瞬时降低。In this paper, the effect of introduction of fault current limiter (FCL) is investigated when it is used in a distribution systems. A line-to-line short circuit fault is assumed to happen at the source side terminal or load side of one of the feeder lines. For three locations of FCL, the current limiting performance and the instantaneous voltage drop at a load bus are calculated by electric magnetic transients program (EMTP). The results show that FCL which is located at exit of bus can get a great effect on both the limitation of fault current and suppression of bus voltage drops.
