Title:
METHOD AND DEVICE FOR TRAIN OPERATION OPTIMIZATION
Document Type and Number:
WIPO Patent Application WO/2022/205175
Kind Code:
A1
Abstract:
A method for train operation optimization, comprising: acquiring a virtual scene model of a traction power supply system for trains, the virtual scene model corresponding to an operation scene of the traction power supply system (21); establishing an operation optimization model, which is used for determining, on the basis of train states of the trains in the virtual scene model, corresponding train actions, which are used for updating the train states of the trains (22); and by utilizing reinforcement learning, iteratively adjusting, on the basis of the simulation power of the virtual scene model in the updated train states, a model parameter of the operation optimization model, thus training the operation optimization model (23). In the method, not only are energy consumption-related factors, such as geographic information, train resistance, and train power characteristics, brought closer to the actual circumstances, but the energy consumption of the entire traction power supply system serves as the starting point, rather than considering only the traction energy consumption of a single train, thus allowing operation optimization to be more comprehensive and accurate.
