摘　　要：目的:为提升基于超级电容储能的现代有轨电车储能系统配置设计能力和车辆运营现场应用的时效性和经济型,需对有轨电车超级电容储能系统的容量配置、充放电策略和故障判断等关键技术进行深入研究。方法:结合实际商业运营线路特征,通过牵引计算与超级电容能量仿真计算,给出超级电容容量最优配置方法,并依据超级电容容量的配置设计以适应车辆的超容动力总成。根据超级电容储能型现代有轨电车车载储能系统到站充电的及时性需求和超级电容的大电流快速补电能力设计了超级电容的充放电策略,并基于此充电策略在充电过程中进行超级电容故障的判断。通过仿真进行剩余电量的校核,验证储能式有轨电车动力性能要求和充电的时效性和冗余能力。结果及结论:基于超级电容的高功率密度和高强度电流能力的优势,对超级电容容量进行合理配置,通过线路能量仿真与实际运营结果相互验证,证明了以超级电容为储能载体的无网供电系统方案,完全能满足全线路无接触网有轨电车的动力性能和能量需求。Objective:To enhance the design capability of modern tram energy storage system based on super-capacitor energy storage and to improve the timeliness and cost-effectiveness of vehicle operation on-site application,it is necessary to conduct in-depth research on key technologies such as the capacity configuration,charging and discharging strategies,and fault diagnosis for the tram super-capacitor energy storage system.Method:Considering the characteristics of actual commercial operation lines,through traction calculation and super-capacitor energy simulation calculation,an optimal configuration method for super-capacitor capacity is proposed.A super-capacitor powertrain system adaptable to the vehicles is designed based on this super-capacitor capacity configuration.To meet the timely charging requirements at stations and leverage the high-current rapid replenishment capability of supercapacitors,charging and discharging strategies for the super-capacitor energy storage system in modern trams are developed.Additionally,fault diagnosis is carried out on super-capacitors during the charging process.Simulation is conducted to validate the remaining energy capacity,ensuring compliance with the power performance requirements of energy storage trams and assessing the timeliness and redundancy capacity of the charging process.Result and Conclusion:Based on the advantages of super-capacitors in high power-density and high-intensity current capabilities,a reasonable configuration of super-capacitor capacity is achieved.The energy simulation results are cross-validated with actual operation outcomes,demonstrating that the super-capacitor-based non-catenary power supply scheme fully meets the power performance and energy requirements of the entire route for non-catenary tram systems.
