Research Of Characteristics Of Energy Efficiency And Control Strategy In Urban Rail Transit Operation System

The urban rail transit system is one of the important parts of the urban traffic system.It has the significant effects on solving the traffic congestion problems.While as the scope of the urban rail transit network and the passengers that use the urban railway become larger and larger,the energy consumption has caused public concern.Therefore,it has the practical meanings to prompt the urban rail transit’s development by researching the components and the influence factors of the consumption of the urban rail transit system.This paper is based on the 13th five-years plan project which is named by"Research of the characteristics of the energy efficiency,impact factors and critical link identification",and this paper researches the characteristics and control strategy of energy efficiency by analyzing the energy data from Beijing urban rail transit system.The detail work includes the following aspects.(1)This paper summarizes plenty of the existing research literatures about the energy consumption of the urban rail system and researches the components of the urban rail transit energy consumption system.Then,this paper analyze the relationship between the energy consumption and energy efficiency.Based on this,the influence factors of energy efficiency and characterization parameters are studied from the viewpoint of system.(2)Based on study of the relationship between the energy consumption and feature analysis of urban rail operation system,this paper first time proposes a method which applies the multilayers network model to research the energy efficiency of urban rail transit system.Then the characteristics of the model has been analyzed from topology and information attribute,and the OWA operator is used to obtain the weight of the node.(3)Based on the emergent theory and fuzzy integral,this paper research the computing method of the energy efficiency of urban rail transit system or sub-system in the network model.The crucial node identification method is studied by using the inverse method that computes the energy efficiency characterization parameters.Eventually,the energy efficiency control strategy is proposed based on the energy efficiency scope of the system or the sub-system.(4)This paper proposes the structure designing and demand designing of the energy efficiency management platform of urban rail transit based on the current situation of energy efficiency management.
