摘要
在聚光型太阳能热发电系统中,聚光装置要实时跟踪太阳,须要根据计算出的太阳位置进行跟踪,以提高发电效率;在开环控制的太阳跟踪系统中,太阳位置的计算精度更为重要。文章给出了利用天文测量简历计算太阳位置的具体方法,其结果可以作为太阳视位置的相对标准,文章还将此方法的计算结果与一些经典算法的计算进行了比较。
High-concentration solar thermal-power systems require the Sun to be tracked in real time for improving efficiency of power generating,which is needed to calculate the solar position.The accuracy of sun position computing is more important for opening-loop tracking control sys-tem.The paper presents detail steps about calculating the solar position by utilizing astronomical almanac and the calculated results can be regard as the comparative standard of the apparent solar position.The comparison between a typical algorithm and the presented algorithm has also been carried out.
