Energy-saving maneuvering methods for trains

The present invention provides a method for energy-saving maneuvering of a train. The method comprises: the train is hauled to a certain speed with maximum traction force during a start-up phase, and then the train is alternately selected to run in an idling and constant-speed operation strategy according to the train's operating speed, the line speed limit, the ramp condition, the operating resistance and other information, until the maximum braking condition is adopted before entering a station to make the train accurately stop at a target stopping point in the station. On the basis of reading in the train parameters, line data and planned operating hours, the Brute Force algorithm is used to optimize the transition positions of the above working condition sequences, and the most energy-efficient train maneuvering scheme is obtained by traversing the solution space. The method of the present invention can fully utilize the potential energy of the ramp to provide kinetic energy for the train, reduce the duration of the traction working conditions, and realize the saving of train traction energy consumption.
