Abstract The high frequency resonance caused by the mismatch between the high speed train and the power supply line is analyzed in this paper. The modeling methods of the high-speed railway power supply system and high speed train traction drive system are described in detail. And the characteristic of harmonic current generated by the high speed train is mentioned in theory. The generation mechanism of resonance is investigated based on the traditional power supply line simulation model. Then, according to Beijing-Shanghai line and CRH-380A, the simulation model is built with the MTL model. It’s resulted that high frequency resonances may cause the high value of harmonic voltage. In addition, the distribution pattern of resonant points and impedance characteristic are researched deeply.
