摘　　要：氢电混合动力系统因高效、零碳排放的特点成为轨道交通转型升级最具前途的动力源,高效的能量管理控制策略可提升混合动力系统的经济性和使用寿命。文章基于典型市域车辆动力和能量需求,建立了适用于城市轨道交通车辆的混合动力模型,采用模糊逻辑控制策略进行能量分配,并利用梯形隶属函数和Mamdani模糊推理方法进行去模糊处理。仿真结果表明,运用模糊控制能量管理策略的混合动力城市轨道车辆能兼顾列车动力需求、燃料电池系统输出特性和超级电容系统输出特性,实时调整列车能量分配,实现良好的燃油经济性和系统效率。与传统受电弓弓网供电相比,整车效率提高约25.36%,节能效果显著;且燃料电池功率输出未发生突变,保持在最佳功率范围内运行。The hydrogen-electric hybrid has emerged as the most promising power source for the transformation and upgrading of rail transit owing to its high efficiency and zero carbon emission.In this context,control strategies aimed at efficient energy management are crucial for improving the economic efficiency and service life of such hybrid power systems.This paper presented a hybrid power model specifically developed for urban rail transit vehicles,which was established based on the power and energy requirements of typical vehicles used in urban and suburban traffic.This model incorporated a fuzzy logic control strategy for energy allocation.Moreover,a trapezoidal membership function and the Mamdani fuzzy inference method were employed for fuzzy processing.Simulation results show that hybrid power urban rail vehicles utilizing an energy management strategy based on fuzzy control effectively balance train power demands,the output characteristics among fuel cell systems,and supercapacitor systems,and achieve improved fuel economy and system efficiency through real-time adjustments of energy allocation.Compared with the traditional power supply mode using OCS systems,the proposed strategy improves vehicle efficiency by about 25.36%,and demonstrates significant energy-saving effects,while remaining the optimal power range without abrupt changes in fuel cell power output.
