城轨交通车辆应急自牵引能耗需求分析及仿真

当牵引网无法正常供电时，城轨车辆通过车载储能系统作为储备电源实现应急移车，从而将列车安全行驶至车站疏散乘客，避免造成人身伤害和经济损失。针对上述情况，结合上海轨道交通11号线车辆电气参数及线路情况，基于PSCAD／EMTDC仿真软件对城轨车辆的电气特征进行建模并通过现场试验数据对仿真模型进行校验和修正。定性分析了车辆应急自牵引时不同运行工况对功率、能耗需求的影响。最后，基于上海轨道交通11号线昌吉东路站至赛车场站的区间线路，通过仿真模型计算车辆在特定工况下应急自牵引时的功率、能耗需求。

Analysis and Simulation of Urban Railway Trains' Energy Consumption Requirement under Emergency Self-traction

When urban railway power system can＇t supply power, the trains can carry passengers to next station with energy storage system on board under the emergency self-traction mode. So passengers can escape safely and personnel injury and economical losses can be avoided . Under the above background, in this paper the electric simulation model was established based on the ~leetric structure of Shanghai Metro Line 11 and the PSCAD/EMTDC software. Furthermore, simulation results were compared with experimental datas and the model was corrected. Then the electrical power and energy consumption of trains were analyzed when working at different emergency traction mode. At last, based on the northern section of Shanghai Metro Line 11, the trains＇ power and energy consumption requirement were calculated through the simulation model when trains were driven under emergency self-traction mode in the line section.
