The invention provides a multi-source hybrid shunting locomotive power system and a management strategy, and the method comprises an energy storage system which is electrically connected with a shunting locomotive traction converter, the energy storage system supplies power to a traction motor and an auxiliary system which are connected with the traction converter through the traction converter, and the traction motor controls a wheel pair; the energy storage system comprises a storage battery pack and a DC/DC converter; the range extender is used for charging the energy storage system, and when the residual electric quantity of the energy storage system is lower than a preset value, the range extender is started to charge the energy storage system. The energy storage system is charged through the range extender, so that the shunting locomotive can adapt to various different environments and working conditions, the multi-source power shunting locomotive power system convenient to transform and manufacture is high in energy efficiency ratio, compared with a pure oil power system, generation of a large amount of waste gas caused by idling operation and frequent alternating load of a diesel engine is reduced, and the energy efficiency of the diesel engine is improved. And the system is low in maintenance cost.

    本申请提供了一种多源混合的调车机车动力系统及管理策略,其中,方法包括与调车机车牵引变流器电连接的储能系统,储能系统通过牵引变流器为与牵引变流器连接的牵引电机和辅助系统供电,实现牵引电机控制轮对;储能系统包括蓄电池组和DC/DC变换器;还包括为储能系统充电的增程器,当储能系统的剩余电量低于预设值时,启动增程器为储能系统充电。本申请通过增程器为储能系统充电使得调车机车能够适应多种不同环境和工况,便于改造和制造的多源动力调车机车动力系统,能效比高,且相比纯油动力系统,减少了柴油机因需要怠速运转,频繁处于交变负荷中导致废气的大量产生,且本系统维护成本低。
