基于地铁编组列车运行数据拟合的牵引能耗模型研究

城市轨道交通进入网络化运营阶段后,其运输需求呈现快速增长、结构复杂等特征,运输组织优化需求不断增加,根据客流规律合理组织运力显得十分必要。在行车密度、大小交路调整手段的基础上,为了提升高峰期列车载客能力,降低平峰期列车空载数量,实现节能与便捷的统一,提出灵活编组手段对运输组织进行优化。在节能方面,列车牵引能耗占有较大比重,为了在运能优化及节能之间找到平衡点,需对灵活编组列车牵引能耗进行分析,作为协调便捷性及经济性的参考依据。本研究通过分析历史运营数据,形成一定的能耗规律,采用多因子拟合的方法建立灵活编组列车能耗模型,并通过迭代法逐渐逼近不同编组列车实际能耗情况。

Research on Traction Energy Consumption Model Based on Metro Train Operation Data Fitting

After the subway enters the network operation stage, its transportation demand presents the characteristics of rapid growth and complex structure, and the demand for transportation organization optimization is increasing.It is very necessary to reasonably organize the transportation capacity according to the passenger flow law. On the basis of the traffic density and the adjustment means of large and small routing, in order to improve the passenger carrying capacity of trains in peak period, reduce the number of empty trains during peak period, and realize the unity of energy saving and convenience, flexible marshalling means is proposed to optimize the transportation organization. In terms of energy saving, the energy consumption of train traction accounts for a large proportion.In order to find a balance between optimization and energy saving, it is necessary to analyze the traction energy consumption of flexible marshalling trains as a reference for coordination convenience and economy. In this paper, through the analysis of historical operation data, a certain energy consumption law is formed, and the energy consumption model of flexible marshalling train is established by multi factor fitting method, and the actual energy consumption of different marshalling trains is gradually approached by iterative method.
