This paper proposes a new fault location algorithm based on two-phase voltage and current measured at the power system side for unbalanced power distribution systems. Taking single-phase-to-ground fault as an example, the paper elaborates the algorithm for feeders with and without laterals. A simple feeder in power distribution system and IEEE-13 node power distribution system are used as test systems...
This paper firstly evaluated the impedance method and traveling waves method for fault location, and studied the robustness of fault location method based on impedance. Then it proposed an assembled fault location method for a transmission line based on single-terminal electrical quantities, in which the fault zone was firstly determined by impedance method with robustness then the accurate fault...
