APPLICATIONS OF SOLAR SIMULATOR IN THE CALIBRATION AND TEST OF RADIATION INSTRUMENTS

该文主要介绍了由TM 50 0F太阳模拟器和旋转工作台组成的具有多功能辐射仪器室内检测设备的结构、原理及应用。利用该设备可对太阳辐射测量仪器进行灵敏度的校准 ,由实验可知 ,总辐射表室内外灵敏度检定结果非常一致 ,其误差在± 0 .6%之内。也可进行余弦、方位响应误差 ,倾斜误差 。

To evaluate the solar radiation measurement data and instrument specifications, the new versatile laboratory test facility for solar radiation instruments has been developed. It consists of an available solar simulator and a rotating mechanism with an instrument mount. The spectral distribution is in accordance with Air Mass 1.5 global spectral conditions. Directionally, tilt and non linearity errors of pyranometers can be tested by using this facility. Satisfactory results have been obtained according to calibration measurements of pyranometers. It is shown that the difference values of the sensitivity are within the range of ±0.6% measured in the outdoor exposure.
