摘　　要：文章介绍了光伏电池在工程应用中常用的数学模型与电路模型,应用光伏电池工程参数,结合MatlabEmbebed function,通过Matlab/Simulink软件建立仿真模型。在常用扰动观察法的基础上对其进行改进,并进行仿真研究,对比改进前后两算法最大功率点跟踪曲线,证明了改进后的算法能够有效地减少最大功率点跟踪的振荡现象,并且减少其跟踪时间和扰动次数,能更好地发挥光伏电池的性能。This article introduces the mathematical and circuit model for photovoltaic cells used in engineering, and establishes the simulation model using Matlab/Simulink software based on the engineering parameters of the photovoltaic cells and Matlab Embebed function. The improved algorithm is proposed based on traditional perturbation and observation method, and the curves of maximum power point tracking are acquired by simulation. Comparing with the curves before and after improving, the result shows that the improved method can suppress the oscillation of the maximum power point tracking, reduce the tracking time and perturbation times, and make the photovoltaic cells performance better.
