Abstract
Embodiments of the present invention provide a grid-connected power supply control system for an urban rail vehicle and an urban rail vehicle, the control system includes a first relay and an intermediate voltage bus contactor, the first relay is connected to the intermediate voltage bus contactor and a processor so as to receive a first control command sent by the processor, and control opening or closing of the intermediate voltage bus contactor according to the first control command. In the grid-connected power supply control system, the opening or closing of the intermediate voltage bus contactor is controlled by the first relay according to the received first control command, and is not controlled by high and low levels output by a network system, thus even an input/output module of the network system fails, the train power supply system be remained in a grid-connected power supply mode until the first relay receives a command for controlling opening, thereby greatly improving utilization rate of the grid-connected power supply mode.
