摘　　要：交流列车过分相问题通常可以采用柔性地面过分相方法解决,但是,对于多流制电力机车,在中性区完成供电制式的切换,情况要复杂很多,目前却少有研究。基于车载切换结合车身动能的方式,提出一种旨在供电制式切换过程中稳定多流制电力机车直流环节电压的方法,并选择具有代表性的某一型号多流制电力机车为研究对象。首先,介绍了该型号多流制电力机车的拓扑结构;然后,针对该车型设计了供电制式切换方法;最后,通过硬件在环实验平台,对所提出的供电制式切换方法进行了实时仿真,验证了所提方法的良好直流环节稳压效果。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.
