摘　　要：为提高燃料电池混合动力列车的燃料经济性,实现混合动力系统功率的合理分配,对以燃料电池、超级电容和动力电池为动力源的混合动力轻轨列车进行研究。通过分析混合动力系统结构,建立各动力源模型和基于列车自动运行(ATO)模式的系统仿真模型。在保证列车动力性能和燃料电池平稳运行的前提下,以合理分配功率为目标,提出一种基于10个工作模式的能量管理策略,以供能量管理系统根据需求进行选择。仿真结果表明:燃料电池在其高效运行区域内平稳工作,建立的系统模型满足列车运行仿真的需求;相比燃料电池两档式工作策略,所提出的能量管理策略耗氢量减少约17.4%;相比动力电池优先回收制动能量策略,回收的再生制动能量增加约8%。In order to improve the fuel economy of the fuel cell hybrid power train and realize the reasonable power distribution of the hybrid power system,a fuel cell-ultracapacitor-battery powered hybrid light rail train was studied.By analyzing the structure of hybrid power system,the model of power supply and the system simulation model based on the automatic train operation （ATO）mode were established.To ensure the reasona-ble power distribution under the premise of satisfying the dynamic performance of the train and the smooth op-eration of the fuel cell,an energy management strategy based on ten operation modes was proposed for the en-ergy management system to select different modes according to the demand.The simulation results indicate that the fuel cell works smoothly in its high efficiency area,and the system model could well meet the demand of the hybrid train operation simulation.In addition,compared with the strategy of the two-stage work of the fuel cell,the proposed energy management strategy reduces hydrogen consumption by about 17.4%.Compared with the strategy in which the battery is used to first recover the braking energy,the proposed energy manage-ment strategy increases recovered regenerative braking energy by about 8%.
