摘要
研究了单列和多列列车运行能耗优化决策问题。城市轨道交通系统对能源的需求量非常大,通过对列车的合理调度,可使列车的运行能耗进一步降低。列车运行环境和线路路型的复杂性,导致列车运行过程中其本身所受到的力是随时变化的。通过模拟现实列车运行状态得出优化模型,具有十分重要的理论意义和应用价值。主要采用极大值原理、非线性方程模型、多目标二次规划对列车消耗的能量进行优化。在能量最优化的情况下,对速度与位移和时间与速度的变换规律进行了研究。
Energy consumption of metro in operation is studied, including both the single train and the multiple trains. Since the energy consumption of urban rail transit is very large, reasonable scheduling of trains will effectively reduce the energy consumption, because the stress on the train changes due to the operation conditions and the line complexities. By simulating the operation of metro train, an optimum model is established, which has important theoretical and practical values. Maximum principle, nonlinear equation model and multi-objective quadratic programming are used to optimize the energy consumption. Finally, in the optimization condition, the changing laws of subway tram speed and movement, speed and time are studied.
