The conventional approaches to distribution network fault location has certain drawbacks in terms of complexity, especially the fault occurred in the branch lines. In this paper, a novel fault location method based on D-type traveling wave was proposed. This method choose the measurement point which the initial traveling waves first reached as the reference measurement point, and the distance between multiple failure points received a fault traveling wave signal to the reference measurement point was calculated. Then, the maximum distance between multiple failure points to the reference measurement point was selected as location of the final failure point. The simulation result with ATP simulation software and MATLAB software show that the proposed method can achieve fault location fast and accurately within a very short period. Compared with the existing algorithms, this method was consistent whether the fault occurred in the main line or branch lines, which improved the accuracy and reliability of the traveling wave fault location in distribution network.
