光伏发电跟踪控制系统设计

Design of Track Control System in PV

太阳能光伏电池阵列的发电量与阳光入射角角度有关,光线与光伏阵列平面垂直时发电量最大。采用光线自动跟踪的方式,使太阳能电池板始终保持与太阳光垂直,这样可以大大提高光伏阵列的发电量。文中介绍了双轴太阳光跟踪控制系统,该系统具有结构简单、稳定性好、精度高的特点,对其推广普及具有广阔的应用前景。

The generating capacity of the Solar Energy Photovohaic Cell arrays is associated with the incidence angle of the sunnight, the power generation is the largest when rays being perpendicular to the vertical planes of photovoltaic arrays. Adapting automatic tracking rays techniques could always make solar panels perpendicular to sunlight, so as to increase the generating capacity of the Solar Energy Photovoltaic Cell arrays greatly. The dual axis tracking system control to track the sun which is introduced by the article, has many advantages,such as a simple structure,good stability, high accuracy, which is helpful in using prospect to its spread and popularity .
