The invention discloses a railway track engineering vehicle operation neutral section passing control method and a control system, and the control system comprises ground magnetic inductors and disconnection and connection signboards which are installed at the two sides of a line. The pantograph, the transformer, the four-quadrant rectifier, the traction converter, the auxiliary converter, the traction motor, the auxiliary power source, the middle direct-current link and the magnetic inductor detection device are installed on the rail engineering vehicle, and the controller is used for controlling the rail engineering vehicle. And the power supply of the intermediate direct current link is gradually switched from the four-quadrant rectifier to the auxiliary power source, and is gradually switched back to the four-quadrant rectifier from the auxiliary power source when the neutral section is recovered. The controller can control the back-and-forth seamless switching of the contact network power supply and the auxiliary power supply under the vehicle operation neutral section passing working condition, so that the whole vehicle auxiliary equipment is not powered off, the vehicle impact is reduced, the operation interruption is avoided, and the pantograph-catenary safety is ensured.

    本发明公开了一种铁路轨道工程车辆作业过分相控制方法及控制系统,该控制系统包括安装于线路两侧的地面磁感应器和断、合标志牌,安装于轨道工程车辆上的受电弓、变压器、四象限整流器、牵引变流器、辅助变流器、牵引电机、辅助动力源、中间直流环节、磁感应器检测装置及对轨道工程车辆进行控制的控制器,在控制器的控制下,在车辆过分相开始时,中间直流环节的供电电源从四象限整流器逐步切换到辅助动力源,过分相恢复时,从辅助动力源再逐步切换回四象限整流器。能够在车辆作业过分相工况下,控制器控制接触网电源和辅助动力源两种电源的来回无缝切换,实现整车辅助设备不断电,降低车辆冲击,避免作业中断,保证弓网安全。
