Autotransformer (AT) all-paralleling feeding systems have been widely used in high-speed railways in China. At present, short circuit faults in traction networks are mainly divided into three types, such as T-R, F-R and T-F. When permanent faults occur on traction power supply network, all parallel AT feeding systems are changed into direct power supply mode. If the fault is a compound fault, i.e., T-R-F fault, the traditional fault location based on reactance-distance method will have a large error. Formula of measuring reactance in a compound fault was deduced and fault location errors of a compound fault in direct power supply mode were analyzed in this paper. And then, a new correction scheme was proposed under the existing conditions. MATLAB/Simulink simulation results show that there is almost no error in the correction results under different transition resistance and fault distance.
