【摘要】：本文中采用微型燃气轮机(下简称微型燃机)作为电动汽车的增程器,对其进行性能仿真和起动控制研究。首先以模块化方法建立各组件稳态数学模型,依据质量守恒和能量守恒原则建立增程器联合运行条件,确定微型燃机共同工作线;接着建立起动和停车过程的动态模型,制定微型燃机控制规律,即供油量随相对转速的变化规律。仿真结果表明:微型燃机以设计工作转速稳定运行时,热效率、燃油消耗率和涡轮前温度均满足设计要求;应尽可能增大回热度,以提高微型燃机的热效率。台架试验结果表明:依据仿真结果确定的供油规律、起动时序和控制系统能够保证微型燃机成功起动、在设计工作点稳定运行和安全停车。
[Abstract]:In this paper, micro gas turbine (micro gas turbine) is used as the range booster of electric vehicle, and its performance simulation and starting control are studied. Firstly, the steady state mathematical model of each component is established by modularization method, and the combined operation conditions of range booster are established according to the principles of mass conservation and energy conservation, and the common working line of micro gas turbine is determined, and the dynamic model of starting and stopping process is established. The control law of micro gas turbine is established, that is, the change of fuel supply with relative rotational speed. The simulation results show that the thermal efficiency, fuel consumption rate and turbine front temperature can meet the design requirements when the micro gas turbine operates stably at the design speed, and the heat recovery degree should be increased as much as possible in order to improve the thermal efficiency of the micro gas turbine. The results of bench test show that the starting time sequence and control system can ensure the successful start of the micro gas turbine, stable operation and safe stop at the design work point according to the fuel supply law determined by the simulation results.
