摘要
Abstract
Due to the complexity of distribution network structure,the number of faults in distribution network is increasing gradually.Thus,a method based on improved time domain inversion for typical fault section location in radial distribution net-work with distributed generation(DG)is studied.According to the wave theory,the distribution parameters are set in the three-phase distribution network,and the distribution network grounding fault equation is established.Based on the time difference of lines,the fault signal interval of distribution network is divided by D-type traveling wave method.Combined with the reflection relation,the time domain inversion algorithm is improved,and the fault signal is used as the reflection wave source to locate the fault section of the distribution network under the function of the mirror principle.The experimental results show that when 1515 kHz is used as the acquisition frequency,the proposed method can fined out the fault section accurately,which has application prospects.关键词
