Modeling and Energy Management Strategy of Hybrid Locomotive

针对混合动力内燃机车,基于车辆动力性分析软件ADVISOR,建立包括6个牵引电机联合驱动模型和轴重转移模型的串联式混合动力调车机车模型。以此为基础,建立恒温器控制与功率跟随控制相结合的混合动力内燃机车控制策略。在机车手柄位操纵的基础上,该控制策略可根据列车所需求的功率调节内燃发动机及驱动电机的输出功率,并引入电池荷电量(SOC)补偿方法,通过控制电池充放电,保证电池SOC维持在一定范围内,使发动机工作在最优区域,从而减小了燃油消耗。

This paper presented secondary development of ADVISOR software and built series hybrid electric shunting locomotive model which included the six motor combined drive sub-model and axle load transfer sub- model. The control strategy of the hybrid electric locomotive takes the handle position control mode as the ba- sis, modulates the output power of the engine and motors according to the power required by the train, and controls the charge and discharge of the battery group to keep the change of SOC within the right bounds and the engine working in the optimum area so as to decrease fuel consumption effectively.
