Study on Energy-saving Operation of Subway Train Dispatching

本文对轨道交通单或多列车面向节能的优化决策进行研究.列车需求能源的量极大,对轨道车辆合理的调配,降低运行能耗的研究意义重大.列车运行所处环境的复杂性和对轨道线路的起伏性,致列车受力是随时变化的.实现通过模拟轨道列车运行研究出优化模型,应用价值和理论意义重大.采用极大值原理、多目标二次规划、非线性方程模型最优化轨道列车所耗能量,在能量最优化情况下研究了位移、速度和时间、速度的规律变换.

We study the subway train dispatching problem based on energy-saving operation in this paper.By using the optimized dispatch method,the energy is saved.The optimization model is established by analyzing the forces of subway train and the undulate of railway track.Simulation of the model is run in Matlab to find an optimal operating diagram.Maximum principle,nonlinear equation model,and multi-objective programming are used to find the best combination of subway train speed and movement and time.
