In accordance with the problems of phase selection method based on difference of phase-to-phase current, that is, phase selection mistake when double-phase ground fault occur and insufficient sensitivity of phase selection when the positive and negative sequence impedances of system are not equal, a new power system phase identification method based on difference value was proposed. The method combined difference of phase voltages with difference of phase-to-phase current, and three generalized admittances were defined to identify phases by comparing their values. The simulation results showed that this method could identify phases correctly on different fault location and different fault resistance, it has sufficient sensitivity and high reliability.
