【摘要】：隨著塔式太陽能發(fā)電技術(shù)的進(jìn)步,如何布置高效低成本的塔式太陽能電站鏡場,已成為提高太陽能集熱效率的關(guān)鍵問題之一。其中,陰影和遮擋效率作為鏡場光學(xué)效率的重要組成部分一直以來都是計(jì)算的難點(diǎn)。結(jié)合兩種傳統(tǒng)陰影和遮擋的計(jì)算方式——射線追蹤法和平板投影法,提出一種新的計(jì)算方法,該計(jì)算方法包括高效的預(yù)判斷模型和改進(jìn)的效率算法兩部分,將該算法與已有的改進(jìn)算法進(jìn)行對(duì)比,研究結(jié)果表明:不論是計(jì)算精度還是計(jì)算速度,改進(jìn)后的算法都明顯優(yōu)于已有的改進(jìn)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.
