| 摘 要： | 为了克服传统固定电压法和扰动法存在的缺陷,提出了基于三点最小二乘法的最大功率点跟踪方法.该方法将定步长与变步长相结合,提高了追踪最大功率点的准确性、快速性以及输出电压的稳定性.利用Simulink建立仿真模型,在不同的起始电压和步长的情况下,追踪光伏电池的最大功率点.仿真及实验结果表明:三点最小二乘在最大功率点跟踪控制过程中跟踪精确,系统工作稳定,输出功率有明显提高.

| Abstract: | Targted at overcoming the defect of the traditional methods of constant voltage and disturbance,this paper introduces a new method based on the least squares method of three dots.The method is capable of an improvement in the accuracy and speed of MPPT(Maximum Power Point Tracking) and the stability of the output voltage in combination with fixed and variable steps.The model of the photovoltaic system,based on the Simulink,is designed for tracking the maximum power under the circumstance of different steps ... |
