The invention discloses a double-current system city domain train traction high-voltage control system and method. The system comprises a power supply system detection device, a system selection switch, a roof switch, an alternating-current main circuit breaker, a high-voltage isolation switch, a direct-current high-speed circuit breaker and a traction high-voltage control unit. The power supply system detection device is connected with a contact network, and is used for judging whether a current high-voltage system of a train is in a DC 1500V direct current mode or an AC 25kV alternating current mode; and in a DC1500V direct current mode, the system selection switch and the roof switch are closed, and the DC1500V high-voltage circuit is connected to the direct current input end of the traction converter box body through the direct current high-speed circuit breaker. The invention provides a traction high-voltage control system and a traction high-voltage control method for a double-current urban train, which can control the on and off of a high-voltage switch according to the detected current traction power supply system parameter, thereby realizing the full-automatic switching of the traction power supply system of the urban train between direct current (DC) 1500V and alternating current (AC) 25kV.
