基于动态客流的城市轨道交通牵引能耗测算

节能是轨道交通可持续发展的重要目标,对牵引能耗的准确测算有助于探索节约能源.分析列车与牵引能耗的线性关系和动态客流在不同时区段的特征,并引入关键系数单耗指标,以此建立了一种地铁列车牵引能耗测算模型,该模型更加贴合线路特征和客流动态特征,大大降低了测算误差,与现有的预测方法比误差更小.通过研究不同时区段的单位能耗可以为既...

Calculation of traction energy consumption of Urban Rail Transit Based on dynamic passenger flow

Energy saving is an important goal of sustainable development of rail transit.Accurate calculation of traction energy consumption is helpful to explore energy saving.This paper analyzes the linear relationship between train and traction energy consumption and the characteristics of dynamic passenger flow in different time sections,and introduces the key coefficient unit consumption index,so as to establish a metro train traction energy consumption calculation model,which is more suitable for the line characteristics and passenger flow dynamic characteristics,greatly reduces the calculation error,and is smaller than the existing prediction methods.By studying the unit energy consumption of different time sections,it can provide a reference for the energy consumption estimation of existing lines and the planning and design of new lines.
