为了实现混合动力列车的计算仿真,建立混合电源系统模型,并提出一种混合电源系统控制策略.在此基础上,通过对混合电源系统与列车纵向动力学系统的耦合分析,给出了基于该电源系统控制策略的列车运行目标速度曲线计算算法.利用MATLAB/Simulink对系统建模,对列车在某线路上的运行过程进行了仿真.仿真结果表明,系统控制策略能够满足列车的运行性能,列车自动控制(ATC)系统能够精确的控制列车跟踪计算的目标速度曲线运行,混合电源回收了41%的再生制动能量,控制策略和目标速度曲线计算算法达到了设计目标.
In order to achieve a numerical simulation of hybrid electric trains, a mathematical model and a control strategy for the hybrid power system were proposed. By analyzing the coupling relationship between the hybrid power system and longitudinal dynamic system of a train, an algorithm based on the proposed control strategy was provided to calculate target speed profiles of the hybrid power train. In addition, using MATLAB/Simulink to build a system model for the train, simulation of the train~ operation process on a railway line was made. The results show that the control strategy can meet the operational performance of the train, the automatic train operation （ATC） system can accurately control the train to track the target speed profiles, and 41% of the braking energy is recovered by the hybrid power system. Therefore, the system control strategy and the calculation algorithm of train target speed profiles can achieve the design goal.
