The invention discloses a power supply system and method for connection of a motor train auxiliary circuit and a train power supply circuit of a motor train unit. The system comprises a DC600V train power supply bus; an auxiliary circuit bus of the first motor vehicle; the connecting circuit is connected between the DC600V train power supply bus and the auxiliary circuit bus; the first contactor is arranged on the connecting circuit; and the control unit is configured to control the first contactor to be communicated with the connecting circuit when the first motor vehicle has no electric energy supply, so that the DC600V train power supply bus powered by the second motor vehicle supplies power to the auxiliary circuit bus of the first motor vehicle. According to the technical scheme, under the condition that the motor vehicle does not have an electric energy source, the working requirements of the control system, the auxiliary system and the life equipment can be met by communicating the column supply bus with the auxiliary bus, the working redundancy and flexibility of the auxiliary system and the control system of the motor vehicle and the emergency capacity during faults can be improved, and the safety of the motor vehicle is improved. And the purposes of saving energy, reducing emission and improving the comfort of a driver and passengers can be achieved.
本发明公开了一种动车组动力车辅助电路与列供电路贯通的供电系统及方法。所述系统包括:DC600V列车供电母线;第一动力车的辅助电路母线;连接电路,连接在DC600V列车供电母线与辅助电路母线之间;第一接触器,设置在连接电路上;控制单元,配置为:当第一动力车自身无电能供应时,控制第一接触器连通连接电路,使得由第二动力车供电的DC600V列车供电母线向第一动力车的辅助电路母线供电。通过本发明的技术方案,在动力车自身无电能来源的情况下,可通过列供母线与辅助母线贯通来实现控制系统、辅助系统及生活设备的工作需求,有利于提升动力车辅助系统和控制系统工作的冗余性和灵活性以及故障时的应急能力,并能达到节能减排、提高司乘人员的舒适性的目的。
