Abstract
Distribution network fault location technology is currently mainly concentrated in sub section positioning and based on the offline signal injection method precise positioning stage, this paper proposes a new online traveling wave fault location method based on the correlation matrix, the method based on line distributed terminal high sampling data waves, with terminal data construction association matrix, through the correlation matrix of the symmetry and correlation determine fault section and identify abnormal data set, on the basis of further accurate fault location, so as to improve the reliability and accuracy of fault location in distribution network.
