塔式太阳能电站定日镜场布局研究
摘要：对基于辐射网格布局和无遮挡损失原则所衍生出的无遮挡（EB）布局、无阻塞（No blocking-dense）布局、经验型（DELSOL）布局3种塔式定日镜场布局进行了研究。对这3种布局的数学模型进行了归纳，结合塔式电站Gemasolar的部分设计参数，分别根据3种布局模式采用SolarPILOT软件对镜场进行建模仿真。利用MATLAB对建模所得镜场坐标数据进行处理，得到径向间距和方位间距变化曲线，验证了3种布局数学模型的合理性。通过分析各镜场中基础环和交错环的排布特点得出镜环布置规则，同时从镜场的定日镜数量、光学效率、土地利用率、接收能量等方面对比不同布局的性能，分析其优缺点。结果表明：在镜场半径为1 000 m的范围内，No blocking-dense布局下镜场的年均光学效率和土地利用率最高，EB布局次之，但EB布局下定日镜数量和镜场接收能量最多，DELSOL布局的各项性能特性均最低。
Abstract:Three tower heliostat field layouts, EB, No blocking-dense, and DELSOL derived from the radial staggered layout and the principle of no blocking loss, were studied. After summarizing the mathematical models of the three heliostat field layouts, combined with some design parameters of Gemasolar power tower plant, the software SolarPILOT was used to model and simulate the heliostat field according to the three layout modes. MATLAB was used to process the coordinate data of the heliostat field obtained by the modeling, and the change curves of radial spacing and azimuth spacing were obtained, so as to verify the rationality of the three layout mathematical models. The layout rules of the heliostat ring were obtained by analyzing the arrangement characteristics of the basic ring and the staggered ring in each heliostat field. At the same time, the performance of different layouts was compared from the number of heliostats, the optical efficiency, the land utilization ratio and the receiving energy of the heliostat field, and their advantages and disadvantages were analyzed. The results show that in the range of 1 000 m radius of the heliostat field, the average annual optical efficiency and land utilization rate of the heliostat field under the No blocking-dense layout are the highest, followed by the EB layout. However, the number of the heliostats and the receiving energy of the heliostat field under the EB layout are the largest, and the performance characteristics of the DELSOL layout are the lowest.
