The application discloses an electrified railway traction power supply system and method. The system comprises a power supply unit, a hybrid energy storage unit, a traction power supply adjusting unitand a traction network unit. The power supply unit charges the hybrid energy storage unit, the hybrid energy storage unit provides power for the traction network unit to meet the power supply requirement of a locomotive, and the traction power supply adjusting unit is connected with the traction network unit to adjust the power balance between two power supply arms of the traction network unit. According to the electrified railway traction power supply system and method, the traction power supply adjusting unit is used for optimizing the capacity configuration of a traction transformer and anenergy storage converter; the traction transformer and the energy storage converter are prevented from being influenced by asymmetric loads when the discharge of the hybrid energy storage unit meetsthe energy consumption requirement of the locomotive/motor train unit; the utilization rates of the traction transformer and the energy storage converter are increased substantially;and the hybrid energy storage unit is used for isolating the direct electrical connection between the power grid and the traction power supply unit, so that the loose coupling between the power grid and the railway traction power supply network is realized.
