基于MPPT算法的温室大棚太阳能电池板供电系统

Solar panel power supply system for greenhouse based on MPPT algorithm

由于蔬菜大棚一般都在野外,且现代化蔬菜大棚中有许多传感器,使用太阳能电池板和蓄电池能够缓解电网压力,以及达到节能环保的作用。以太阳能电池板为主要研究对象,针对太阳能电池板所接受光照和其周围温度的改变,以及蓄电池本身的局限性设计了MPPT算法和三段式充电算法组成的系统,实验证明该系统能够使太阳能电池板的使用率得到近一步提升。

Sensors are widely used in modern vegetable greenhouses, which are usually built in the wild. Using solar panels and batter- ies can ease the power grid pressure, and achieve the targets of energy conservation and environmental protection. Aiming at the illumi- nation and surrounding temperature of solar panel, and considering the limitation of batteries, a system based on MPPT algorithm and three stage charging algorithm is designed. The experiment verified that this system can enhance the utilization rate of solar panels.
