摘要:采用情景分析法，搭建了城市轨道交通车网仿真模型，对发车间隔、上下行发车时间差、载客量、行车密度、路况地理状态等因素对再生制动能量利用率及牵引变电站牵引能耗的影响进行了分析，给出再生制动能量利用率的主要影响因素.通过再生制动能量利用率较低的工况仿真，分析了站点列车制动电阻开启次数、低电压出现次数与该站点再生制动能量的利用以及电能质量间的作用关系.以上海地铁线路运营时段的发车间隔为例，运用仿真方法，探讨了地面储能系统容量配置与城市轨道交通发车间隔的取值控制策略.研究成果可为城市轨道交通节能提供理论指导.



Abstract:Finding out the factors influencing the utilization rate of regenerative braking energy of Urban Rail Transit(URT) vehicles is of great significance for improving the scientificity of energy-saving measures in URT operation. Based on a built simulation model, the scenario analysis method was used to quantitatively analyze the influencing factors of departure interval, time difference, passenger load, traffic density and road condition on regenerative braking energy utilization rate and traction energy consumption of traction substation. The main factors were given. The multi-condition simulation of the low regenerative braking utilization indicate that the opening times of train braking resistance and the occurrence times of low voltage at the station are strongly correlated with the utilization of regenerative braking energy and power quality of the station. Taking the departure interval of multi--period operation of Shanghai metro line as an example, the simulation strategy of URT departure interval was discussed to guide capacity allocation of the stationary energy storage system. The results of this paper can provide reference for the formulation of energy-saving measures for URT.
