Abstract In recent years, stable operation and the rapid processing of the fault of traction power supply system is becoming increasingly important, which requires the traction network can be accurately located. On the basis of summarizing the existing methods, this paper analyzes the effect of skin effect on fault location .The relationship between fault current time constant and the orbital unit of inductance and resistance are obtained. Based on the above analysis, Under consideration set effects of skin effect, by containing forgetting factor least square method of system identification track impedance parameters are obtained. Then the simulated annealing the least-squares mixed ranging method measurement algorithm are presented in this paper. And the fault data of simulation model built by Matlab/Simulink and actual fault data in a city is performed to verify the feasibility and accuracy of the method.
