Harmonic Analysis and Suppression Method of Train Network Side Based on Multiplex Control Strategy

Abstract

This is the paper style requirement for the Chinese Control Conference. The writers of papers should and must provide normalized electronic documents in order for readers to search and read papers conveniently. In order to reduce the harmonics pollution by AC drive electric locomotive and EMU in traction power supply, this paper presents a side harmonic suppression method for train network based on multiple control strategy. Firstly, the structure and topology of multiplex control rectifier are introduced, then the influence of carrier modulation and carrier shift on train harmonic voltage and current is analyzed in detail. Finally, the validity of the harmonic analysis method and the effectiveness of the harmonic suppression method are verified by simulation and experiment.
