优选地，纯电工况下动力电池最低可用SOC限制在15％。同时，机车控制单元控制四象 限整流模块工作于逆变模式，四象限整流模块作为逆变器输出380V/50Hz交流电，经过正弦波滤波后供给辅助系统用电。
优选地，参考图2所示。动力电池上电逻辑：控制电源上电后，机车控制单元正常工作的条件下，机车发送唤醒信号给BMS系统，BMS管理系统开始工作。当打开钥匙开关后，机车控制单元收到总控钥匙开关信号，机车控制单元系统向BMS系统输出上电信号，BMS管理系统闭合高压箱接触器。当机车控制单元监测到BMS系统高压箱接触器闭合信号后，机车控制单元控制动力电池预充电接触器闭合，动力电池经预充电电阻向中间直流回路电容充电，当中间直流回路电压大于480V时，接通放电接触器，动力电池开始向中间直流回路供电，从而实现向牵引电机供电。
更进一步地，动力电池上电过程中，机车控制单元自身检测相关系统是否有影响上高压的故障存在。机车控制单元与BMS通信，BMS发送自检状态数据，若无影响上高压的故障数据，机车控制单元相关系统也无影响上高压的故障存在，机车控制单元发送上高压的信号给BMS系统。机车控制单元自身检测相关系统是否有需要下高压的故障存在，机车控制单元与BMS通信接收BMS系统是否有需要下高压的故障存在。若有需要下高压的故障存在，机车控制单元首先控制机车卸载，停止使动力电池放电或充电的工作，在断开相关接触器后，机车控制单元撤消“上高压信号”。
优选地，当所述调车机车控制系统处于纯柴油工况时，所述动力电池与所述预充电模块断开，所述柴油发电机组经四象限整流模块为所述牵引电机供电。纯柴油工况禁止回馈制动。
进一步地，当所述调车机车控制系统处于纯柴油工况时，所述四象限整流模块工作于PWM整流模式，输出恒定的DC608V直流电压。
优选地，如图3所示。当所述调车机车控制系统处于混合工况。在调车机车处于低手柄位时，例如手柄位低于5位。由动力电池优先向牵引电机供电，当动力电池SOC低于30％时，启动柴油发电机组向牵引电机供电，柴油发电机组在满足牵引功率需求的情况下，剩余功率给动力电池充电。在调车机车处于高手柄位时，例如手柄位高于5位。启动柴油发电机，控制四象限整流模块的输出实现柴油发电机组与动力电池混合为所述牵引电机供电。其中，高手柄位、低手柄位就是指司机操作的司控器的高档位和低档位，高手柄位意味着机车要加速。
进一步地，当所述调车机车控制系统处于混合工况，且在调车机车处于低手柄位时，所述四象限整流模块工作于PWM整流模式，四象限整流模块控制输出恒定电流向动力电池充电，直至所述动力电池SOC高于95％时，停止柴油机发电机组工作。
优选地，当所述调车机车控制系统处于地面充电模式时，由所述工业发电机组经四象限整流模块为所述动力电池充电，且所述四象限整流模块工作于PWM整流模式，四象限整流模块控制输出恒定电流向动力电池充电。
本发明中的四象限整流模块具有两种工作模式，既能作为PWM整流器，又能作为逆变器，从而简化了系统配置，有利于检修维护。完善的软件控制策略，实现柴油发电机组和动力电池完美的混合工作。
前述本发明基本例及其各进一步选择例可以自由组合以形成多个实施例，均为本发明可采用并要求保护的实施例。本发明方案中，各选择例，与其他任何基本例和选择例都可以进行任意组合。本领域技术人员可知有众多组合。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
