Analysis of Train Working Diagram of Urban Rail Transit with Energy Storage Vehicles
Energy storage rail transit vehicles adopt in-vehicle energy storage media without the need for additional power supply facilities such as overhead contact networks,it reduces the landscape impact and engineering investment of elevated lines,and has significant advantages in low volume urban rail transit lines.At the same time,the energy storage power method has a special impact on train operation organization.This paper was based on a rail transit line that used battery energy storage vehicles and centralized charging in parking lots,and analyzed its influencing factors on the public transportation mode,high frequency and safety in operation organization of urban rail transit.Taking into account these factors,the constraints of train working diagram in urban rail transit lines was presented,including general constraints such as number of trains,number of trains during peak hours,daily train operation plan,turnaround time,interval operation time,dwell time,depot entry and exit time,depot distribution and function,as well as special constraints such as operating energy consumption,battery capacity,charging time,depot tracks and train positions,and sequence of entry and exit depot.At last in study case of an urban rail transit line in Hengyang with Guideway Rubber-Typed Tram System,the train working diagram was presented and its indicators were analyzed and summarized with suggestion put forwards.
