摘要
提出一种双轴光电跟踪方式:在相互正交的双轴平面上由光敏电阻组成阵列圆,在其中心设置遮挡杆.根据遮挡杆和其阴影长度判断出太阳光的位置,分别算出双轴应该旋转的角度,实施自动跟踪.试验结果证明,该跟踪系统相对固定角度太阳能跟踪系统,提高发电效率25%;相比实时跟踪系统,降低耗能68%.
We design a system based on double-shaft rotary angle. Double orthogonal shafts is on a panel with a circular array consisting of 32 photosensitive resistances and a lever on the center of the panel. The sun can be positioned by the length of lever and the length of its projection. The test results show that the tracking system can improve the power generation efficiency by 25 % compared to the fixed angle system, and can also reduce consumption of mechanical eaergy by more than 50% compared to real-time tracking system.
