An optimal configuration algorithm of traveling wave fault location unit

In order to insure the reliability and economy of network-based traveling wave fault location, an optimal configuration algorithm for network-based traveling wave fault location unit is proposed. It can be analyzed that different network configuration and specific fault location have great influence for the shortest transmission path of initial traveling wave, and therefore affecting the configuration of traveling wave fault location unit. Primarily, setting each line as fault line respectively, the complicated network can be converted into simplified one by using Floyd algorithm, which keeps the fault line in any case. The nodes can be divided into two arrays according to the fault location in simplified network. In the case of different fault line, minimum sharing set can be calculated by the nodes from two arrays, and thus the nodes need to configure traveling wave fault location can be decided. When the fault occurs on special condition, which will detail below, the relevant scheme is suggested. The simulation results illustrate the reliability and feasibility of the algorithm.
