Abstract

The invention discloses a traveling wave fault location method, device, equipment and storage medium. The method includes: acquiring detection data sent by each traveling wave detection device; determining a target traveling wave detection device and an abnormal traveling wave detection device according to the detection data sent by each traveling wave detection device; when it is determined that there is an abnormal traveling wave detection device, Determine the target distance according to the detection data sent by the target traveling wave detection device and the pre-stored distribution network topology; the detection data sent by the target traveling wave detection device includes the initial time when the line fails, the initial time when the initial traveling wave head reaches the target traveling wave detection device Target time: determine the location of the line fault point according to the target distance, target time, initial time and ranging algorithm. The present invention can eliminate the abnormal traveling wave detection device, can screen out effective data, avoids the problem that the fault point cannot be determined due to the fault of a certain traveling wave detection device, and improves the reliability of locating the fault point.
