摘要
针对传动扰动观测法具有跟踪速度慢、跟踪精度差及在最大功率点处易发生误判等问题,提出了一种基于滞环比较的新型扰动观测法。该方法通过对光伏电池进行分析,根据其数学模型,利用Matlab/Simulink软件搭建出一种实用光伏电池模型,并对其进行仿真研究。仿真结果表明,相较于传动扰动观测法,该方法具有启动速度快、跟踪精度高、在最大功率点处振幅小、不易产生误判等优点。
In order to solve thedisadvantages of traditional perturbation and observation method,such as slowtracking speed,poor tracking accuracy andhigh possibility of misjudgment at maximum power point,a newperturbation and observationwas proposedbased on hysteresis comparison.The photovoltaic cells were studied and a practical photovoltaiccells model was builtwith the Matlab/Simulink.The simulate results showed that the newmethod had faster starting speed,better tracking accuracy,smaller amplitude at the maximum power point and less misjudgment than the traditional perturbation and observation method.
