The traction transmission system comprises a hybrid power source composed of an internal combustion generator set and a power battery, a diesel engine drives a main generator to generate a three-phase alternating current, the three-phase alternating current is rectified by a rectifier diode and then is connected with the power battery in parallel after being subjected to voltage boosting/reducing through a bidirectional DC/DC module, and then the three-phase alternating current is connected with the power battery. A direct-current traction motor of the direct-current hybrid power locomotive is jointly driven; the internal combustion generator set comprises a diesel engine and a main generator which are connected in sequence. Energy conservation and emission reduction of the locomotive are achieved, the application cost of the locomotive is reduced, and accurate control over the locomotive is improved.
