中文摘要

随着电力系统规模扩大与互联程度加深,系统短路容量增加导致故障电流水平显著上升。本文提出一种新型桥式故障限流器(FCL)结构,通过基于电容的非超导设计,有效限制故障电流,提升电网故障穿越能力,且无需超导材料,具备更高的工程应用可行性。

English Abstract

Taking into account extension of power systems, their interconnections, and increment of load demand, power capacity of networks is increased and the impedance of sources is decreased. Such variations in power systems resulted to occurring high ratings of fault currents. Fault current limiter (FCL) can be practically utilized in order to interrupt fault currents to a specified amount without requi...
