基于光伏电池的工程模型,在Matlab/Simulink仿真环境下,搭建了光伏阵列仿真模型,可模拟仿真给定光伏模块参数、光伏阵列串并联方式、外界环境变化下的光伏阵列特性曲线,并具有最大功率跟踪功能,其中采用考虑外界环境因素变化的恒电压控制方法,方法简单易行。该模型有较好的通用性,为光伏发电系统的研究提供了仿真模型和平台。

Based on the engineering model of photovoltaic battery, the simulation model of photovoltaic array is established on Matlab/Simulink environment. The model can simulate the given parameters of photovohaic module, the series and parallel connection mode of photovohaic array, and the characteristic curves of photovoltaic array during the variation of external environment, and has the tracing function of maximum power in which it uses the constant voltage control method considering the variation of external environment factor, and is simple and practicable. The model has a better commonality, and it provides the Simulation model and platform for the research of photovoltaic power generation system.
