节能坡与编组方案影响下的地铁列车运行能耗分析

地铁列车在运行过程中，能耗受线路条件以及运营组织方案影响较大。为了更准确地模拟线路运营条件与列车运行能耗之间的关系，在列车运行计算的基础上，分析列车在运行过程中的特点，设计牵引-惰行-制动的站间运行模式下的列车仿真模型，研究列车节能坡设计以及编组方案对列车运行能耗的影响。该模型主要由列车受力分析、站间操纵策略设计以及能耗计算3个部分组成，并在Visual studio平台上设计不同的线路条件及编组方案进行仿真实验，分析其对列车运行能耗的影响规律以及能耗的变化特点。研究发现，采取合理的节能坡设计以及编组方案有利于降低列车运行能耗。

Energy consumption of rail-transit trains considering energy-saving slope and train marshaling scheme

The energy consumption of urban rail-transit trains is mainly influenced by their line conditions and operation organization scheme. To accurately simulate the relationship between line operating conditions and train operation energy consumptions, this study presents a rail-transit train simulation model that has an energy-efficient speed profile. Each interstation section consists of three phases: maximum acceleration, coasting, and maximum braking. The proposed model considers the characteristics of the train operation between the stations and the impact of the train marshaling scheme and the design of the energy-saving slope on the energy consumption of trains. This simulation model consists of three components: train force analysis, interstation train operation strategy design, and energy consumption calculations. Different line conditions and train marshaling schemes are designed on the Visual studio platform to perform the simulation, and the effect on the energy consumption of trains and the characteristics of energy consumption are analyzed. The results show that logical energy-saving slope design and train marshaling scheme plans are beneficial to reduce the train operation energy consumption.
