The result of fault phase selector during power swing is a precondition to switch off the correct fault phase and ensure the right operation of distance protection relays. Based on the analysis of the performances of present selector during power swing， such as the delay of operating and being easy to select false fault phases， and therefore causing false operating of distance protection relay， a novel fault phase selector is presented. The selector firstly uses the zero-sequence and negative-sequence components to distinguish the different fault types， and based on the fault phase recognition， the impedance measure in the presented selector is not used， and Clark transformation is adopted and the model components ofα andβ are used to select the farther fault phases. This selector fully utilizes the characteristics of zero-sequence， negative-sequence， and the advantages of model components， such as little computation error without phasor deflection during power swing. It can effectively avoid the malpractices of impedance selector during power swing. The simulation results based on RTDS are presented， and the theory and testing results show that this phase selection measure can quickly and correctly select the fault phases during power swing in an reliable way.
