The invention provides a grid-connected power supply control system and method for a full-automatic driving rail transit vehicle, and the system is characterized in that when the traffic vehicle is powered on and activated, a vehicle control module controls a medium-voltage bus contactor to be disconnected, and transmits an independent operation instruction to each auxiliary inverter; each auxiliary inverter executes self-checking operation according to the independent operation instruction, and when normal work is detected, an auxiliary contactor in the auxiliary inverter is controlled to be closed so as to supply power to a load; when the vehicle control module detects that the traffic vehicle enters the full-automatic driving mode, the detection instruction is cancelled, so that the auxiliary inverter controls the auxiliary contactor to be disconnected; after each auxiliary contactor is disconnected, the vehicle control module controls the medium-voltage bus contactor to be closed and execute grid-connected operation, and the auxiliary contactors only need to be disconnected once, so that the problem of on-load breaking of the medium-voltage bus contactor is solved, and the service life of the auxiliary contactors and the medium-voltage bus contactor is prolonged; and the reliability of the full-automatic vehicle driving auxiliary system is improved.
本发明提供一种全自动驾驶轨道交通车辆并网供电控制系统及方法,该系统中当交通车辆上电激活时,车辆控制模块控制中压母线接触器断开,并向各个辅助逆变器发送独立运行指令;每一辅助逆变器根据独立运行指令执行自检操作,当检测到正常工作时,控制辅助逆变器中的辅助接触器闭合,以为负载供电;车辆控制模块检测到交通车辆进入全自动驾驶模式时,撤销检测指令,以使辅助逆变器控制所述辅助接触器断开;待各个辅助接触器断开后,车辆控制模块控制中压母线接触器闭合,执行并网操作,辅助接触器只需断开一次,解决了中压母线接触器带载分断的问题,提高了辅助接触器与中压母线接触器的使用寿命,提高了全自动驾驶车辆辅助系统的可靠性。
