摘　　要：针对电力电子开关自动过分相技术应用引起的严重列车冲动问题,文章提出了一种适用于极短时网压中断的动态力矩卸载与加载控制策略,实现列车在失电时间内仍能保持列车牵引力,主动抑制列车冲动;揭示了异相网压极短时切换工况下变压器励磁涌流产生原理,并提出了适用于异相网压切换的励磁涌流主动抑制策略;阐述了一种基于坐标变换的快速单相锁相环与传统锁相环相结合的优化锁相策略,可有效解决电子开关过分相工况下列车控制异常以及牵引力恢复时间长的难题。神朔铁路正线试验中模拟列车满载通过电力电子开关过分相工况,充分证明了所提控制策略的正确性与有效性。In view of the serious train impulse caused by the application of the power electronic switch automatic passing neutral section technology,a dynamic moment unloading and loading control strategy was proposed which was suitable for the very short-term network voltage interruption,to realize the train traction force maintaining during the power loss time to actively suppress the train impulse;The generation mechanism of inrush current of transformer under the condition of extremely short-time switching of different phase network voltage was revealed,and the active suppression strategy of inrush current suitable for different phase network voltage switching was put forward;an optimized phase-locked strategy was expounded based on the combination of fast single-phase phase-locked and traditional phase-locked loop with coordinate transformation,which could effectively solve the problems of abnormal train control and traction long recovery time under the condition of passing neutral section with electronic switch.In the main line test of Shenshuo railway,the simulation of full load train passing through the power electronic switch neutral section,which fully proved the correctness and effectiveness of the proposed control strategy.
