摘要
为了观察燃料电池系统在工作时氢气子系统、氧气子系统和热管理子系统各部分变量的变化规律,根据燃料电池系统的结构和工作原理,采用AMESim与Simulink联合仿真,建立燃料电池系统级一维仿真模型,分析给定工况下燃料电池系统的动态特性,并利用PID控制算法调控系统温度。仿真发现,燃料电池通过输入相应的燃料产生电流以满足功率的需求,且温度处于较佳区间内。结果表明,仿真模型与理论分析比较吻合,验证了仿真模型的正确性,对燃料电池系统的开发具有指导意义。
In order to observe the changing rules of the hydrogen subsystem,oxygen subsystem and thermal management subsystem when the fuel cell system is working,according to the structure and working principle of the fuel cell system,a onedimensional simulation model of the fuel cell system level is established by AMESim and Simulink,the dynamic characteristics of the fuel cell system under a given working condition are analyzed,and the system temperature is regulated and controlled by PID control algorithm.Simulation results show that the fuel cell generates current to meet the power demand by inputting corresponding fuel,and the temperature is in a better range.The results show that the simulation model is in good agreement with the theoretical analysis,which verifies the correctness of the simulation model and has guiding significance for the development of fuel cell systems.
