In order to avoid the complex network solution operation of the ring network in the method of traveling wave fault location, a new method of traveling wave fault location based on Dijkstra algorithm is proposed. After a certain transmission line fault in the power grid, the initial traveling wave arrival time is recorded at all substations. Dijkstra algorithm is used to calculate the shortest path, shortest path distance matrix is established, and the shortest path matrix and the initial traveling time are utilized to calculate the fault distan...
