This paper presents a fault zone discrimination and a more accurate fault location estimation technique in the AC traction power supply system with a branch line. In order to verify the performance of the proposed technique, we model the AC traction power supply system with a branch line using power analysis program and verify the performance of the fault zone discrimination and fault location estimation through various fault simulations.
