摘　　要：太阳能光伏电池是光伏发电的主要部件,根据等效电路图推导得出其数学模型,并利用MATLAB/Simulink仿真软件搭建仿真模型,在不同光照及温度下得出其相应的光伏特性曲线。同时对最大功率点跟踪(MPPT,maximum power point tracking)控制进行分析,提出了一种新的模糊控制建模方法,并与常规的扰动观察法和电导增量法进行了仿真比较。经过仿真表明,这种新的模糊控制方法具有更快的跟踪速度,更好的平滑性和抗干扰性。Solar photovoltaic cell is the core of photovoltaic power generation,and its mathematical model can be deduced according to the equivalent circuit diagram,and the simulation model can be established by MATLAB/Simulink simulation software,and the corresponding photovoltaic characteristic curve can be obtained under different lighting and temperature.At the same time,a new fuzzy control modeling method is proposed based on the analysis of MPPT control,which is compared with the traditional perturba⁃tion observation method and conductance increment method.Simulation results show that this new fuzzy control method has fastertracking speed,better smoothness and anti-interference.
