摘　　要：采用时间跟踪与光感跟踪相结合的方法,研制了全天候双模式太阳方位跟踪控制系统.系统具有控制方式转换、时间控制以及光感控制等功能.光伏电池阵列的发电量与光线入射角有关,光线与光伏阵列平面垂直时发电效率最高.采用自动跟踪太阳的方式,使太阳能电池板始终保持与太阳光垂直,可大大提高光伏阵列的发电量.双轴跟踪控制系统具有结构简单、能耗低,跟踪精度高等优点.支架纵梁采用"Z"型设计结构,确保运转自如,实现了仰俯跟踪的动力节能.An innovative control tracking method which combined the time tracking with the photovoltaic tracking method was presented based on MCU and an all-weather control system for sunlight tracking was studied. The system inclUdes the switching control, time control, and photovoltaic control module. The generating capacity of the Solar En- ergy Photovoltaic Cell arrays is associated with the incident angle of the sunlight. The power generation efficiency would be the highest when rays are perpendicular to the planes of photovoltaic arrays. Adapting automatic tracking techniques could always make solar panels perpendicular to sunlight. So the generating capacity of photovoltaic cell ar- rays has been increased greatly. The dual axis tracking system has many advantages, such as a simple structure,low en- ergy consumption, high accuracy. Bracket stringer is designed with ＂Z＂ structure to ensure operating freely, and to a- chieve power saving for pitch tracking.
