摘　　要：为了全面评价燃料电池有轨电车混合动力系统的经济性和提高系统的耐久性,计及燃料电池和锂电池寿命;提出了一种基于混合动力系统寿命的价值损耗评价函数。采用实测工况的需求功率,利用价值损耗函数对状态机、功率跟随和等效氢耗最小3种能量方法进行经济性分析。仿真结果表明:状态机策略的价值损耗最小,相比功率跟随和等效氢耗最小策略,该方法使系统的价值损耗分别减小了11.0%,6.3%。In order to comprehensively evaluate the economy of fuel cell hybrid power system for tram and improve its durability,a value loss function based on the life of fuel cell and lithium battery in hybrid system is proposed.The demanded power in actual conditions is adopted and the value loss function is used to analyze the three energy policies including the state machine,power following,and minimum equivalent hydrogen consumption.The simulation results show that the value loss of state machine strategy is the smallest,and compared with power following and equivalent hydrogen consumption minimization strategies,this method reduces the value loss of the system by 11.0%and 6.3%,respectively.
