摘要
在概述国内外研究现状的基础上,分析影响机车牵引能耗的4类主要因素,提出机车驾驶策略优化研究即在满足安全、准点、舒适等多目标条件的约束下,寻找一条最优速度曲线,使列车由起点到达终点消耗的能量最少。将列车运行的全过程划分为平缓坡、上坡和下坡等多种运行状态的组合,通过建立基于多目标约束的能耗最优控制模型,提出不同阶段对应的机车驾驶策略,并通过实车验证该模型具有显著的节能效果。
Based on summarizing study status in China and foreign countries, this paper analyzes 4 major factors influencing energy consumption of locomotive traction, and puts forward the study on optimization of locomotive driving strategy is to seek a optimum speed curve as to achieve minimum energy consumption of trains from departure to destination under satisfying the multi-objective constraints including safety, punctuality and comfort. The whole process of train operation is divided into multiple running states like gentle slope, upgrade and downgrade, through establishing the optimized control model of energy consumption based on multi-objective constraints, the paper puts forward corresponding locomotive driving strategies in different stages, and then, the energy-saving effect of the model is proved obvious through actual train example.
