太阳能电池板自动追光控制系统设计

Design of control system for solar panel automatic tracking

为实现太阳能供电,介绍了一种太阳自动追踪系统.该系统采用视日运动跟踪与寻求最大功率点相结合的方法,控制太阳能转换利用装置自动旋转去对准太阳,能有效提高太阳能的吸收率.该系统采用单片机作为控制器,小型太阳能电池作为传感器,步进电机作为执行机构.对于各种利用太阳能作为能源的自动装置而言,这种自动追踪系统具有一定的实用价值.

In order to use solar-powered, a system that solar panel can automatic track the sun is produced. The system use combined method of solar movement tracking and maximum power point seeking, it controls solar energy conversion utilization device automatically and rotated it to aim at the sun, and it can raise the solar energy absorption rate. In the system, single- chip microcomputer is used as the controller, small solar battery is used as sensor, and stepper motor is used as actuating mechanism. The system has some practical value for devices which rely on the solar energy.
