【摘要】：随着塔式太阳能发电技术的进步,如何布置高效低成本的塔式太阳能电站镜场,已成为提高太阳能集热效率的关键问题之一。其中,阴影和遮挡效率作为镜场光学效率的重要组成部分一直以来都是计算的难点。结合两种传统阴影和遮挡的计算方式——射线追踪法和平板投影法,提出一种新的计算方法,该计算方法包括高效的预判断模型和改进的效率算法两部分,将该算法与已有的改进算法进行对比,研究结果表明:不论是计算精度还是计算速度,改进后的算法都明显优于已有的改进算法。
[Abstract]:With the development of tower solar power generation technology, how to arrange the mirror field of tower solar power station with high efficiency and low cost has become one of the key problems to improve the efficiency of solar energy collection.As an important part of optical efficiency of mirror field, shadow and occlusion efficiency are always difficult to calculate.Combined with two traditional methods of shadow and occlusion, ray tracing method and flat projection method, a new calculation method is proposed, which includes two parts: an efficient prejudgment model and an improved efficiency algorithm.Compared with the existing improved algorithm, the research results show that the improved algorithm is obviously superior to the existing improved algorithm in terms of calculation accuracy and speed.
