基于灰色关联度的轨道交通能耗影响因素分析

Influencing Factors of Energy Consumption for Rail Transport Based on Grey Relational Degree

轨道交通节能潜力较大.本文在分析行业统计数据的基础上,利用灰色相关度分析法对轨道交通系统中的城市轨道交通、客运专线以及客货共线铁路的能耗组成以及各主要影响因素的影响重要度进行定量分析.结合行业统计数据,确定分析指标并得出分析结果.研究认为:轨道交通总能耗构成分为机车运行牵引能耗和车站设施能耗两部分.机车运行牵引能耗的大小对决定客货共线铁路和客运专线铁路的能耗起较大作用;而对城市轨道交通系统能耗而言,两个因素的重要度相差不大.不同因素对轨道交通能耗的影响重要度存在差异.

The potential of energy-saving of rail transit is large.Based on the analysis of the industrial statistics data,this paper analyses the energy consumption factor composition and the main influence factors of urban rail transit,passenger-dedicated line and passenger train of the railway line shared by passenger and freight trains using grey relational degree analysis method.Combining industrial statistics data,establish quantify analysis indicators and draw the analysis result.The result shows that,rail transit total energy consumption constitute divided into locomotive running traction energy consumption and the equipment energy consumption in two parts.Locomotive running traction power consumption plays a great role on decision the energy consumption factor of the railway line shared by passenger and freight trains and the passenger-dedicated line.And for energy consumption factor of urban rail transit system,two factors of importance vary slightly.Different affecting factors of rail transit plays a different role on the importance degree of energy consumption factor.
