Dynamics Analysis and Power Allocation Strategy Research for a New Hybrid Electric Urban Rail Vehicle

Article Preview

Abstract:

In order to improve the efficiency and environment-friendliness of urban rail vehicles, a new hybrid electric locomotive is proposed. The general structure of the proposed hybrid electric locomotive is given and analyzed from a dynamics point of view. The calculation method of power output and its allocation strategy is discussed. A simulation is conducted in HELSP(Hybrid Electric Locomotive Simulation Platform) to verify the performance of the power allocation strategy. The result indicates that the function of allocating power can be properly realized, and the regeneration energy from frequent braking can be absorbed by the power storage of the vehicle.
