摘要

本文旨在研究和优化太阳能光伏电站的定日镜镜场布局，以提高能源效率。通过分析光学效率的关键因素，构建了光学效率模型。利用阴影遮挡效率、余弦效率、大气透过率、集热器截断效率和镜面反射率这五个效率因子计算单个定日镜的光学效率。使用 DELSOL 布局作为初始镜场，并通过粒子群算法对镜场设计进行优化。通过多次调整定日镜和吸收塔的位置，计算出定日镜镜场的最佳设计参数，包括吸收塔的位置、定日镜的尺寸和安装高度。结果表明，定日镜场的年平均光学效率为 0.6127，年平均热功率输出为 37.4508 MW。通过优化，定日镜场的年平均光学效率提高到 0.75，年平均热功率输出达到 64.98 MW。此外，研究结果表明，定日镜场具有季节性特征。光学效率和年平均热功率输出每月都在变化。

Optimization of Optical Efficiency Modeling and Heliostat Field Layout of Tower Solar Thermal Power Station

The aim of this paper is to study and optimize the layout of heliostat mirror fields in solar photovoltaic power plants to improve energy efficiency. By analyzing the key factors of optical efficiency, the optical efficiency model is constructed. The optical efficiency of a single heliostat mirror is calculated using five efficiency factors, namely, shadow shading efficiency, cosine efficiency, atmospheric transmittance, collector truncation efficiency, and mirror reflectivity. The DELSOL layout is used as the initial mirror field, and the mirror field design is optimized by the particle swarm algorithm. The optimal design parameters of the heliostat mirror field including the position of the absorption tower, the size of the heliostat, and the installation height were calculated by adjusting the positions of the heliostat and the absorption tower many times. The results show that the annual average optical efficiency of the heliostat field is 0.6127, and the annual average thermal power output is 37.4508 MW. Through optimization, the annual average optical efficiency of the heliostat field is increased to 0.75, and the annual average thermal power output reaches 64.98 MW. In addition, the results show that the heliostat field has a seasonal characteristic. The optical efficiency and the annual average thermal power output change monthly.
