城市轨道交通列车节能问题及方案研究

Train Energy-saving Scheme with Evaluation in Urban Mass Transit Systems

在城市轨道交通中,影响列车运行能耗的因素包括列车的牵引制动性能、列车重量、限速、线路条件、信号闭塞方式以及列车的操纵方式等,通过对相关条件的改变,可以实现列车节能的目的.论文通过案例设计与系统模拟,重点研究了线路条件对城市轨道交通节能的作用.文中分别从曲线(特别是小半径曲线)、坡道(分上、下坡道)以及列车重量等方面对能耗的影响进行了研究,并对节能坡的节能情况进行了分析,得到适合不同区间条件下的节能坡方案.

In the urban rail transport, factors impacting the train operation energy consumption include the performance of train traction and breaking, the train weight, the condition of line, the mode of signal blocking and the mode of train control. The train can achieve energy saving by changing the relevant conditions. By the case design and the system simulation, this paper focuses on the influence of the line conditions on the energy saving of the urban rail transit. This paper studies energy saving from the curve （especially small radius curve）, the ramp （divid- ed into upper and lower ramp） and the train weight. The paper also analyses the energy saving condition of the energy-saving slope, and gets energy-saving programs suitable for different section conditions.
