摘要
Abstract
The problem of AC train passing neutral section can be solved by ground's flexible passing neutral section method.However,for multisystem electric locomotives,the switching of power supply system in neutral zone is much more complicated,but there is little research at present.Based on the approach of vehicle switching combined with vehicle kinetic energy,a method to stabilize the DC-link voltage of multisystem electric locomotive in the process of power supply system switching was proposed,and selected the typical multisystem electric locomotive of certain model as the research object.Firstly,the traction drive system topology of the multisystem electric locomotive was introduced.Then,a power supply system switching method was designed for it.Finally,real-time simulation of the proposed power supply switching method was conducted on a hardware-in-the-loop experimental platform,and the good DC-link voltage stabilization effect of the proposed method was verified.关键词
