面向虚拟编组建立阶段的重载列车速度曲线优化方法
Speed Trajectory Optimization for Heavy Haul Trains during Virtual Marshalling Formation Stage
快速建立列车之间的虚拟编组有利于提升运行效率。结合重载列车的特征,提出面向虚拟编组建立阶段的速度曲线优化方法。首先,根据通过道岔的次序将列车分为领头车和跟随车,对于领头车最小化其到达线路终点的时间,对于跟随车最大化其与前车的编组时间,并减少动能变化量。考虑牵引/制动/基本阻力、运行速度、边界条件、安全防护和编组状态等约束条件,构建混合整数非线性规划模型。针对其中的非线性项,采用分段线性和大M法进行了处理,将原模型转换为混合整数线性规划模型,并按照预设的算法步骤使用GUROBI进行求解。最后,基于包神铁路和韶山4B型电力机车的实际数据验证该方法的有效性,并分析不同目标速度和区段长度对虚拟编组时间的影响。结果表明,该方法在多种条件下均能有效实现列车之间的虚拟编组,为速度曲线规划提供参考。
The rapid formation of virtual marshalling between trains can significantly increase operation efficiency. Considering the characteristics of heavy haul trains, this paper proposed a speed trajectory optimization method for the virtual marshalling formation stage. At first, trains were categorized as either leading or following vehicles based on their sequence through turnouts. For the leading train, the objective was to minimize the time required to reach the endpoint, while for the following train, the objective was to maximize the marshalling time with the preceding train and minimize energy variation. Constraints such as traction/braking/basic resistance force, operational speed limits, boundary conditions, safety protection, and marshalling status were considered to formulate a mixed-integer nonlinear programming model. To address the nonlinear terms, piecewise linearization and the big-M methods were applied so that the original model could be converted into a mixed-integer linear programming model, which was then solved using GUROBI according to the predefined algorithmic steps. Finally, the effectiveness of this method was verified based on real-world data from the Baotou-Shenmu Railway and the Shaoshan 4B electric locomotive. The impact of different target speeds and section lengths on the virtual marshalling time was analyzed. The results show that the proposed method effectively achieves virtual marshalling between trains under various conditions, providing insights for speed trajectory planning.
