Abstract

Abstract: The passing neutral section scheme by using electronic switches instead of vacuum circuit breakers can shorten dead time of locomotives, and can eliminate the problem of locomotive deceleration. This paper constructed the traction power supply system model and the detailed main circuit model of Chinese standard EMU, including high voltage system and traction converter based on Matlab/Simulink. Then the scheme of using electronic switch is designed, and the influence of delay time required for the detection and action of the devices is considered. By comparing the simulation and measurement data, the accuracy of the model is verified, and analysed the transient response of passing neutral section when considering the delay time.
