摘要：

太阳光线角度测量中,开关量测量方法存在精度差、光敏元件多的问题;模拟量测量方法也存在测量范围小、光敏元件特性不一致性且难以处理的缺点。针对这些问题,文中提出了带有光电池的旋转圆柱体法。圆柱体表面开有沿轴向、倾斜的特殊槽,待圆柱体旋转后,通过测量底部光伏电池最大电流处的旋转角度,即可计算出方位角和高度角。文中方法采用了抛物线插值,提高了最大值处的旋转角度精度。实验结果表明,该方法能取得较好测量精度。

Abstract:

As for the solar ray angle measurements, the switching measurement method has disadvantages including poor precision and a large number of photosensitive elements while analog measurement have the deficient of small measurement range, inconsistent photosensor characteristics. To solve these problems, a method of rotating cylinder with PV cell was proposed in the study. The cylindrical surface has a special groove that is axially and inclined. After the cylinder was rotated, the azimuth and elevation angles were calculated by measuring the rotation angle of the maximum current at the bottom of the photovoltaic cell. Parabolic interpolation was utilized to increase the accuracy of the rotation angle at the maximum point of quadratic curve. Experimental test showed that the proposed method could achieve better measurement accuracy.

Key words: solar energy, sun ray angle, rotating cylinder, PV cell, PV, sun tracking
