The invention discloses a hybrid power auxiliary transmission system of a direct-current locomotive and a control method of the hybrid power auxiliary transmission system. The hybrid power auxiliary transmission system comprises an internal combustion generator set, a traction motor loop and an auxiliary power supply system. The auxiliary power supply system comprises a bidirectional DC/DC module, a power battery and an auxiliary system; the auxiliary system comprises a DC/AC inversion module, a cooling fan motor, a traction ventilator motor, an air compressor motor and a DC/DC module. The internal combustion generator set is connected with the auxiliary power supply system through a traction motor loop; the two ends of the DC/AC inversion module are connected with the positive electrode and the negative electrode of the power battery respectively. The two ends of the DC/DC module are connected with the positive electrode and the negative electrode of the power battery respectively. Energy of a power battery and an internal combustion engine set of the direct-current locomotive can be mixed to supply power to the locomotive alternating-current auxiliary system; power can be supplied to a locomotive alternating current auxiliary system only through a power battery or an internal combustion engine set.

    本发明公开了一种直流机车的混合动力辅助传动系统及其控制方法,该混合动力辅助传动系统包括:内燃发电机组、牵引电机回路和辅助供电系统;辅助供电系统包括双向DC/DC模块、动力电池和辅助系统;辅助系统包括DC/AC逆变模块、冷却风扇电机、牵引通风机电机、空压机电机和DC/DC模块;内燃发电机组通过牵引电机回路与辅助供电系统连接;DC/AC逆变模块的两端分别与动力电池的正极和负极连接;DC/DC模块的两端分别与动力电池的正极和负极连接。本发明能够实现将直流机车的动力电池与内燃机组两者能量混合为机车交流辅助系统供电;能够实现仅靠动力电池或内燃机组为机车交流辅助系统供电。
