摘要

本文利用Simulink建立了光伏组件的仿真模型。模型只需要厂家给出的四个光伏组件参数，即开路电压$({\ mathm V_{oc}})$、短路电流$({\ mathm I}_{{\ mathm sc}})$、峰值电压$({\ mathm V}_{{\ mathm M}})$和峰值电流$({\ mathm I}_{{\ mathm M}})$，即可准确模拟出不同环境温度和光照强度下组件的I-V输出特性曲线和P-V输出特性曲线。将仿真输出的特性曲线与厂家数据手册给出的图像进行对比，验证模型的正确性。研究了串联电阻Rs对光伏组件输出特性的影响。结果表明，即使很小的串联电阻Rs也会对输出特性产生很大的影响。此外，还对7个光伏组件串联系统的动态特性进行了仿真。

The Research of Photovoltaic Module Based on Simulink

In this paper, the simulation model of photovoltaic (PV) module is established by using Simulink. The model only needs four PV module parameters given by the manufacturer, namely open circuit voltage $({\mathrm V_{oc}})$, short circuit current $({\mathrm I}_{{\mathrm sc}})$, peak voltage $({\mathrm V}_{{\mathrm M}})$and peak current $({\mathrm I}_{{\mathrm M}})$, which can accurately simulate the I-V output characteristic curve and P-V output characteristic curve of the module under different ambient temperature and light intensity. The simulation output characteristic curve is compared with the image given in the manufacturer’s data manual to verify the correctness of the model. The influence of series resistance Rs on the output characteristics of the PV module is also studied. The results show that even a small series resistance Rs has a great influence on the output characteristics. In addition, the dynamic characteristics of system with 7 PV modules in series are simulated.
