摘要：

Based on the travelling wave theory of transmission line, the distributed parameter model of traction power supply network (TPSN) is built in this paper. First, the unit length impedance and admittance of TPSN are obtained by the equivalent reduction method of multi-transmission lines (MTLs). Second, this paper analyzes the transient characteristics of the harmonic currents in different conditions which concludes the different locomotive positions condition, different positions of traction network when locomotive fixed condition and different length of TPSN condition. Finally, in order to evaluate the higher harmonic current influence, it is used to simulate the traction harmonic transient characteristics of dynamic locomotive operation..
