摘要
太阳光线入射角是太阳能辐射效率的重要影响因素,以兰贝特定律为基础,借鉴太阳在地外斜面曝辐量的定义,引入了超调跟踪的概念。在对超调跟踪系统进行了效能分析后发现,实时跟踪系统所能吸收的太阳能最多,但需要实时检测与控制,而固定式太阳能吸收装置利用效率很低。使用超调跟踪系统在1天中仅使接收装置调整3次就可达到平均效率95%以上的效果。
The incident angles of solar rays have great effects on the solar energy radiation efficiency. Based on Lamberfs law and the definition of exposure radiation value within the inclined plane outside the earth surface, the concept of tracking over- shoot is introduced. Through the efficiency analysis of overshoot tracking system, it is found that the received solar energy by a real-time tracking system can reach the maximum, but require system could achieve average efficiency of 95% of the above with the real-time detection and control. The overshoot tracking only adjusting the receiving apparatus 3 times.
