Abstract

Accurate fault location is helpful to improve the stability of power distribution network. With the integration of distributed generations and electric vehicles, the traditional distribution network gradually became the active distribution network, which requires new technologies for fault location. The arise of high-precision micro phasor measurement unit, termed µPMU, satisfies the need of active distribution network. In this paper, a new method based on µPMU is proposed to locate the fault in the active distribution network. The candidate faults are located by the voltage and current information of µPMU at one terminal. To get the actual fault location, the pseudo fault locations are eliminated by phase difference of µPMUs at two terminals. The simulation results show that the location method has high position accuracy, whether in traditional distribution network or in active distribution network, less than 1%. And can satisfy different types of fault with simply installing µPMUs at the two terminals of the active distribution network.
