轨道交通装备用混合动力包构型与能量管理策略OA北大核心CSTPCD
Hybrid power pack configuration and energy management strategy for rail transit equipment
搭载传统燃油动力包的内燃动车组是运行在非电气化轨道交通中的主力机型,存在效率低、油耗高的缺点.针对这一问题,设计了一种轨道交通装备用混合动力包的构型方案,建立了混合动力动车组的数学模型,分析了不同模式下该构型方案的运行状态,结合整车线路运行条件,提出了一种基于动态规划算法的能量管理策略.仿真结果表明,在该能量管理策略控制下,装备混合动力包的动车组相较于纯燃油动车组燃油经济性提升了32.11%.
The main type of rail transit equipment used in non-electrified railways is diesel multiple units(DMUs)powered by traditional fossil fuels,which suffers from low efficiency and high fuel consumption.To address this issue,a configuration scheme for a hybrid power pack for railway equipment was designed,and a mathematical model for the hybrid locomotive was established.The operational status of this configuration scheme under different modes was investigated,and an energy management strategy based on dynamic programming algorithm was proposed,with considering the operating conditions.Simulation results demonstrate that with this energy management strategy,the fuel economy of the hybrid powertrain locomotive is improved by over 32.11%compared to that of the pure fossil fuel locomotive.
