Study on Energy Consumption Simulation Calculation Method of Hydrogen Energy Tram

结合氢能源有轨电车的能源使用特征和运行特征建立了氢能源有轨电车运行能耗的仿真计算方法。首先,将氢能源有轨电车的连续运行曲线离散化;然后,通过各个离散步长内的牵引能耗反算实时牵引电流值;最后,基于氢燃料电池在不同电流值下的能源转换效率函数计算得到氢能源的消耗量。将以上仿真计算方法应用于运营中的佛山高明氢能源有轨电车项目工程,以供氢能源有轨电车项目规划时的车辆配置、场站布局作参考。

An energy consumption simulation calculation method of hydrogen energy tram is established based on characteristics of energy usage and tram operation.Firstly,the continuous running curve of tram is discretized.Then the real-time traction current value is reversely calculated from traction energy consumption within each discrete step size.Finally,the hydrogen energy consumption is calculated based on the energy conversion efficiency function of hydrogen fuel cell under different current values.The simulation calculation method is applied to Foshan Gaoming hydrogen energy tram project,provi-ding reference for vehicle configuration and station layout in hydrogen energy tram planning.
