摘　　要：针对塔式太阳能热发电系统中定日镜布局优化问题,以无遮挡(EB)布局模型为基础,建立光热电站定日镜场光学效率模型,通过与SolarPILOT对相同坐标数据的定日镜场进行效率计算,证明光学效率建模的准确性。通过在种群初始化时加入Kent映射,在迭代过程中添加动态双子群收敛因子、自适应精英非均匀变异、自适应惯性权重得到混合策略鲸鱼优化算法,同时引入非支配排序和拥挤度计算使算法适用于多目标优化问题,最后结合Gemasolar电站的数据以单目标和双目标分别优化EB布局中的关键参数(方位间距因子和极限重置因子),得到最优布局方案。Aiming at the optimization of heliostat layout in solar tower power generation system,an optical efficiency model of heliostat field in solar tower power station is established based on eliminate blocking(EB)layout model.The efficiency calculation of heliostat field with the same coordinate data as SolarPILOT proves the accuracy of the modeling of optical efficiency.By adding Kent mapping during population initialization,adding dynamic double subgroup convergence factor,adaptive elite non-uniform mutation strategy,and adaptive inertia weight in the iterative process,the hybrid strategy whale optimization algorithm is obtained.At the same time,non-dominated sorting and crowding calculation are introduced to make the algorithm suitable for multi-objective optimization problems.Finally,the key parameters(azimuth spacing factor and azimuth spacing reset limit factor)in EB layout are optimized with single target and double target respectively in combination with Gemasolar power plant data,and the optimal layout scheme is obtained.
