摘　　要：传统的短路限流装置大部分串联在电路中,并且仅具备限流功能。此处提出一种新型多目标短路限流装置,系统正常运行时,装置的并联部分补偿负载产生的谐波与无功。系统发生短路时,装置并联部分退出运行,串联部分限流电抗器正常工作用来限制短路电流。这样不仅减少了多种装置带来的占地面积过大,检修维护麻烦等问题,而且大大节约了成本。The traditional fault current limiter series in a circuit mostly,which only have the current limit function.This paper presents a new type of multi-objectives short circuit current limiting device.When the power system runs normal,the parallel part of the device compensates reactive power and harmonic produced by the load.When the pow-er system short-circuited,the parallel part is out of service,the series part can limit the short circuit current.In this way,this device not only solve the problem of the area,meanwhile saving the cost.
