摘　　要：针对太阳能实验研究时域限制的缺陷,设计了一套人工太阳模拟装置。首先从实验光源与太阳光的光谱符合度进行了分析,设计了用高压球形短弧氙灯代替太阳光的实验方案;然后分别对椭球聚光镜的结构设计和反光涂层进行了实验测试;最后对光源辐照度的测试方法进行了改进,设计的辐照度计是对常用的CCD相机加图像分析软件测试辐照度方法的提高。测试结果证明设计的太阳模拟装置可以用于碟式斯特林太阳热发电的实验研究。In view of the limitations of time-domain in studying of the solar energy,one solar simulator is designed.The similarity between the experimental light source＇s spectrum curve and the solar spectrum is studied firstly,the experimental program which uses the short arc xenon lamp as the experimental light source to instead the solar energy is introduced in the experiment;then the experimental design of ellipsoidal collector＇s structure and the reflecting coating are also respectively discussed;Meanwhile,the radiation meter is a prodigious improvement to the current method which depend on the CCD camera and image analysis program in testing the irradiance.It＇s proved that the simulator can be used as an experimental program of the Dish/Stirling Solar Power Generation System.
