| 摘 要： | 为了提高光伏发电系统的输出效率,提出了基于变步长扰动观察法的最大功率点跟踪方法。该控制方法以光伏电池的数学模型为基础,以光伏输出功率的变化为判断依据,通过对光伏电池的输出电压进行调节,从而实现最大功率点跟踪。在Matlab/Simulink下进行了系统的建模与仿真,仿真结果表明该算法能够在快速跟踪最大功率点变化的情况下保证跟踪精度。这说明变步长扰动观察法具有比传统扰动观察法更优异的稳态和动态性能,能够有效提高光伏发电系统的发电效率。

| Abstract: | In order to improve the output efficiency of PV generation system,A novel variable step size perturbation and observation(P&O) method is proposed to track the maximum power point of PV system.Based on the mathematical model of PV system,this method tracks the maximum power point by regulating the output voltage after measuring the changes of its output power.The simulation model of PV system is established,and the experiment is implemented.The experimental results show that the method can track the maximum ... |
