The invention discloses a tractive power supply system with a double-current system for an electrified railway and a power supply method. The tractive power supply system comprises an alternating current power supply component and a direct current power supply component. The alternating current power supply component is used for offering alternating current to supply power. A third breaker and a third disconnecting switch are arranged on one phase of the alternating current power supply component, and a fourth breaker and a fourth disconnecting switch are arranged on one phase of the alternating current power supply component. The direct current power supply component is used for providing direct current to supply power. The direct current power supply component comprises two direct current converting units of the same structure. Two phases of voltage on the secondary side of a traction transformer go through one direct current converting unit respectively, so that the needed direct current is acquired. The divide-shut brakes of a first breaker and a second breaker of one of the two direct current converting units are interlocked with a third breaker, and the divide-shut brakes of a first breaker and a second breaker of the other direct current converting unit is interlocked with the fourth breaker. The power supply method is based on the tractive power supply system. The tractive power supply system with the double-current system for the electrified railway and the power supply method have the advantages that structural principle is simple, the operation is simple and convenient, the application range is wide, and operation is high efficient and economical.
