根据光伏电池的工程数学模型，利用 Matlab/Simulink 建立了仿真模型，通过改变环境参数分析了某型号光伏组件的U-I 、P-U 曲线，仿真结果表明了该模型的适用性。最后针对光伏发电最大功率跟踪(MPPT)问题，采用一种改进扰动观察法(P&O)，仿真图像表明该算法具有较好的输出稳定性，有效提高了光伏发电效率。

In this paper,the PV cell’s mathematical model of engineering is adopted to establish simulation model in Matlab/Simulink.By changing environment parameters,the simulation result shows theU-I and P-U characteristic curves of one PV module,which is produced by a company,are well agreed with its parameters.An improvement perturbation and observation is used in the MPPT simulation,and the result indicates that this algorithm improves the output stability and efficiency of PV system.
