A topology structure of a power battery pack of a diesel-electric hybrid power locomotive; a chopper unit is connected in parallel to a supporting capacitor C, and the chopper unit is further connected to an AC/DC module, a DC/AC module, a reactor unit and a power battery system; the power battery system comprises several sets of power modules; the power modules comprise a contactor unit, a current sensor, a fuse, a power battery, and a voltage sensor; the contactor unit, the current sensor and the power battery are connected in series, and both ends of the voltage sensor are disposed at both ends of the power battery, respectively; a locomotive microcomputer is connected to a DUC controller and a power battery management system, respectively; the DUC controller is connected to the DC/AC module, the chopper unit and the contactor units; and the power battery management system is connected to the contactor units. The provision of the chopper unit and the reactor unit solves the difficulty of control when a plurality of power battery packs are put in, ensures the reliability of the operation of the power battery system and effectively extends the service life of the power battery.
