The invention discloses a double-source motor train unit passing neutral section train supply stable control method which comprises the steps that when a double-source split motor train unit passes a neutral section, the state of an internal combustion power switch is obtained, and if the internal combustion power switch is closed, the rotating speed of a diesel engine is n1, and the internal combustion power torque is T1; electric traction is recovered after neutral section passing, and the electric power torque is T; the state of the internal combustion power switch is obtained again, and if the internal combustion power switch is closed, the rotating speed of the diesel engine is n, and the internal combustion power torque is T2; if yes, the rotating speed of the diesel engine is n0, and the internal combustion power torque is 0; when the double-source centralized motor train unit passes through the neutral section, the state of a power holding switch is obtained, and if the power holding switch is closed, the rotating speed of a diesel engine is n2, and the internal combustion power torque is T1; after the internal combustion power output is stable, the rotating speed of the diesel engine is n3; the rotating speed of the diesel engine after passing through the neutral section is n0, and the internal combustion power torque is 0; electric traction is recovered, and the electric power torque is T. The method enables the train to continuously supply power on an electrified line, ensures that the motor train unit still has a certain traction force in a split-phase non-power area, and slows down the longitudinal impulse of the train.
