A train operation optimization method, comprising: obtaining a virtual scene model of a traction power supply system of a train, the virtual scene model corresponding to an operation scene of the traction power supply system (21); an operation optimization model is established, the operation optimization model is used for determining a corresponding train action according to the train state of each train in the virtual scene model, and the train action is used for updating the train state of each train (22); and iteratively adjusting model parameters of the operation optimization model according to the simulation power of the virtual scene model in the updated train state by using reinforcement learning to train the operation optimization model (23). In the method, factors related to energy consumption, such as geographic information, train resistance and train power characteristics, are closer to actual situations, and the traction energy consumption of a single train is not merely considered from the energy consumption of the whole traction power supply system, so that the operation optimization is more comprehensive and accurate.

    一种列车运行优化方法,包括:获得列车的牵引供电系统的虚拟场景模型,虚拟场景模型与牵引供电系统的运行场景相对应(21);建立运行优化模型,运行优化模型用于根据虚拟场景模型中的每辆列车的列车状态确定对应的列车动作,列车动作用于更新每辆列车的列车状态(22);以及利用强化学习,迭代地根据虚拟场景模型在更新的列车状态下的仿真功率调整运行优化模型的模型参数,以训练运行优化模型(23)。在该方法中,不仅地理信息、列车阻力、列车功率特性等与能耗有关的因素更接近实际情形,而且从整个牵引供电系统的能耗出发,而不仅仅考虑单辆列车的牵引能耗,使得运行优化更加全面和准确。
