摘要
为了提高太阳能光伏发电的效率,设计了一种高精度自动跟踪太阳光的系统。该系统主要采用粗、细调互补型信号采集相结合的方式,实现了对太阳光的大范围、高精度的自动跟踪,实际跟踪精度高达0.1°立体角。实验结果表明:该系统操作简单,跟踪精度高,平均输出功率比固定式光伏发电系统提高了30.7%。
In order to improve the efficiency of solar photovoltaic power generation,this paper design a high precision automatic solar tracking system. The system mainly uses the complementary combination manner of the signal acquisition with coarse and fine tune to achieve a wide range,high precision,allweather automatic tracking of the sunlight,and the tracking accuracy has been up to 0. 1° solid angle.The experimental results show that the system is easy to operate and has high tracking accuracy; and the average output power was 30. 7% higher than that of fixed photovoltaic power generation system.
