摘要
本文设计了一种用于光伏发电系统输出特性研究的模拟试验装置,以达到提升研发效率,降低试验成本的目的。该装置由LED阵列光源、伏安特性检测模块、环境参数检测模块以及数据处理模块构成。其中,LED阵列光源可通过控制不同支路的开关组合和顺序实现光照强度、角度以及均匀度的调节,从而达到模拟太阳光源的效果。为了证明其科学性和有效性,本文基于该装置成功模拟了一天内从早到晚不同时刻的太阳光照变化,并分析研究了太阳能电池阵列在不同光照强度和电池温度下的输出特性,实验现象与文献论述基本一致。由此可见,本文所述试验装置基本满足开展光伏系统输出特性研究的功能要求,并且能够有效提升研发效率,降低项目成本。
In this paper,a simulation apparatus is designed for investigating the output characteristics of photovoltaic power system,so that research efficiency can be improved while the cost is reduced.The apparatus is composed of an LED array ligh t source,an IV characteristic measurement module,an environment detection module,and a data processing module.The LED array light source is able to change the intensity,angle and uniformity of light radiation by alternating the combination and swit ching order of LED light branches,which properly simulate the solar source.In order to prove its feasibility,the developed apparatus is successfully used to simulate the sun light change during a day,from morning to night at several different times.Meanwhile,the dependence of solar cell output characteristics on light intensity and temperature is investigated based on this apparatus,which shows consistent results with that reported in literature.Therefore,the apparatus described in this paper is capable of performin g the study on the output characteristics of photovoltaic system with higher efficiency and less cost.
