Zusammenfassung:	The invention provides an urban rail intelligent traction power supply system and a control method thereof, the system adopts a set of bidirectional converter unit to replace an original set of diode rectifier unit, and a set of energy operation control system is arranged on a top layer to form a novel intelligent traction power supply system. Two traction operation modes are set by comprehensively considering the system safety, the energy-saving effect, the equipment utilization rate and the like, one mode is that a bidirectional converter unit supplies power for main traction, and a rectifier unit is in hot standby; 2, the power of the bidirectional converter unit and the rectifier unit is output in a balanced manner; the energy operation control system effectively distributes power between the bidirectional converter unit and the rectifier unit according to train loads, active traction power supply is achieved, the voltage of a direct-current traction network is improved and stabilized, line loss and rail
