以实验室正在研制的燃料电池混合动力机车作为研究对象,基于ADVISOR平台搭建了燃料电池/锂电池混合动力机车仿真模型,主要包括燃料电池电堆模型、蓄电池模型、牵引电机模型和机车整车模型等,针对具体的行驶工况,在考虑再生能量回收的前提下提出了基于改进功率跟随控制的能量管理策略,仿真结果表明该控制策略能使燃料电池基本按平均功率输出,蓄电池SOC能维持在为稳定的范围以内,机车动力系统也能够很好地满足机车功率需求,机车动力性能良好。
According to the developing fuel cell hybrid locomotive of laboratory, a relatively comprehensive dynamic model of the hybrid locomotive is established on the platform of ADVISOR, mainly including the fuel cell stack model,battery model, traction power model and locomotive model. Then, according to the run conditions of the locomotive,taking into account recovery the regenerative braking energy, an improved power-track control strategy are proposed for the hybrid energy management. Last, the simulation results demonstrate the hybrid system capability to meet appropriate driving cycle and the requirements of the fuel cell and the battery.
