摘　　要：提出了通过两块光电池同步旋转得到的短路电流曲线来求解光线角度的方法。利用产生的短路电流含有交变电流和直流分量的特性,通过DFT将交直流分量分离,根据交流分量的相位和交直流分量的幅度分别求解太阳光线的方位角和高度角。求解过程中考虑了反射的影响和光电池特性不一致的影响。通过试验表明了该方法的有效性。A measurement method is put forward, in which solar ray angles are calculated with short circuit current curves were gotten from two solar cells that were rotating synchronously. Considering AC and DC component in short circuit current of solar cell, azimuth angle is gotten by phase of AC component and elevation angle is gotten by AC/DC amplitude separated by DFT considering different characteristics of solar cell. The test result is presented which shows its effectiveness.
