摘要

故障电流限制器是一种重要的限制故障电流的设备。提出了一种新型内部永磁偏置式的导磁体结构

并构成一种新型磁饱和故障限流器。对这种限流器的工作原理进行了分析

给出了限流器设计的一些主要参数。在220 V系统下设计并制作了限流器模型

并用Matlab对限流器在正常及故障情况下的特性进行了仿真。试验结果与仿真结果基本一致

设计的模型限流器可以达到预期的限流效果。这种新的结构的优点是造价经济、结构简单、反应迅速和不需要检测控制装置。

Abstract

Fault current limiter（FCL） is an important way to limit fault current.This paper introduced a new structure of a permanent magnetic Fault Current Limiter consisting of an annular steel core

permanent magnet and coil.Design and simulation methods are presented.A prototype FCL of 220 V system was designed.The FCL characteristics are simulated using Matlab.The experimental results are in close agreement with the simulation results.The FCL can limit the fault current to expected value.The strongpoint of this new structure is compactness

low cost

responding fast and eliminating detecting devices.
