The invention discloses a power self-adaptive control method, medium and system for an oil-electric hybrid power locomotive. The method comprises the following steps: 1) acquiring bus intermediate direct-current voltage Ureal of the oil-electric hybrid power locomotive; (2) the bus intermediate direct-current voltage Ureal is compared with a preset charging target voltage Ubatcharge, a preset discharging target voltage Ubatcharge and a preset power reduction target voltage Utrage respectively, and the preset charging target voltage Ubatcharge, the preset discharging target voltage Ubatcharge and the preset power reduction target voltage Utrage are compared with the preset charging target voltage Ubatcharge and the preset power reduction target voltage Utrage respectively; wherein the Utragiont is the Utragiont; the method comprises the following steps of: obtaining a Ubatdischargult; the method comprises the following steps of: performing Ubatcharge; when the Ureal is greater than the Ubatch, entering a charging mode; when the Ureal is less than the Ubatdisk, entering a discharge mode; when the Ureal is less than the Ubatdisk, entering the step 3), and when the Ureal is less than the Ubatdisk, entering the step 3); and 3) a traction power control process: obtaining a difference value eptration between a preset power reduction target voltage Utration and a bus intermediate direct current voltage Ureal, obtaining a traction power increase and decrease amount delta P (k) of the current period according to the difference value eptration, and adding the traction power increase and decrease amount delta P (k) of the current period to the actual traction power Plaast of the previous period to obtain a traction power set value Pset of the current period. The method has the advantages of simple control, high power distribution efficiency and the like.
