A train and a traction drive system and control method thereof, which are applied to the technical field of rail transport. The traction drive system of the train comprises: a traction drive system main circuit, a controller, and an active voltage regulation circuit (40) arranged on a direct current bus. The controller is used for determining a voltage reference value of a target capacitor (C1), taking the voltage reference value as a target voltage of the target capacitor (C1), performing feedback control, and outputting a first control quantity; determining a current reference value of a target inductor (L1) on the basis of the current voltage and frequency of a traction network, taking the current reference value as a current target of the target inductor (L1), performing feedback control, and outputting a second control quantity; and superimposing the first control quantity and the second control quantity and modulating a corresponding PWM pulse so as to control on/off of a corresponding switch tube in the active voltage regulation circuit (40).
