随着全国高铁线路的逐步成网,高铁列车区间节能驾驶策略对降低高铁列车区间运行能耗显得尤为重要.论文结合动力学相关知识,构建了一种列车节能驾驶策略模型,通过确定高速铁路列车在区间各工况转换点以及区间最高运行速度的方法来寻找最优节能驾驶策略.最后以CRH3型动车组在京津城际之间运行为例,利用Lingo软件编程可迅速寻找出高铁列车区间最优运行工况转换点,从而确定出局部最优条件下的高铁列车最佳节能驾驶策略.对模型参数(列车区间运行时间)做了灵敏度分析,得出列车在区间的最高运行速度随着区间运行时间的增加而降低的结论.%The study of eco-driving strategies of high-speed trains is crucial to reducing the energy consumption during train operation. The paper proposes an eco-driving model for high-speed trains that captures the train operational dynamics. The proposed model is able to optimize the transition points of train operation and the maximum sectional operation speed. It is shown that the model can be solved efficiently using Lingo and local optimal solutions are reached. A case study is conducted for a CRH3 train operating between Beijing and Tianjin. Sensitivity analyses indicate that the maximum operation speed decreases as the interval travel time increases.
