摘要
Abstract
To enhance the rapid and accurate fault location capability for fault current suppression in existing flexible DC Grid,this paper investigates a back-to-back bipolar flexible DC distribution network.It proposes a fault location method based on an improved Sparrow Search Algorithm(SSA)combined with active current limiting technology,consisting of three stages:pre-location,active fault current limiting,and precise location.In the precise location stage,the improved SSA is introduced to enhance the fault location accuracy and suppress ripple interference.A back-to-back flexible DC distribution network model is constructed in PSCAD/EMTDC.The simulation results show that the average fault location error is less than 0.3％and the maximum error is less than 0.55％under different transition resistances,noise interferences,and signal asynchronization,verifying the effectiveness of the proposed fault location method.关键词
