Optimal design of aiming strategy for solar power tower stations
摘要
Abstract
To achieve uniform heat flux distribution on the receiver surface,an optimization method for he-liostat aiming strategy in solar power tower station is proposed.First,the heliostat field is divided into zones based on the calculated instantaneous optical efficiency of heliostats throughout the entire field,and different aiming factors are designed for heliostats in different zones.Then,the spot size of each heliostat is calculated according to the aiming factor,and the relative spot size is determined by the ratio of spot size to receiver size,thereby planning the aiming point distribution.Finally,a genetic algorithm is employed to optimize the heliostat aiming point distribution,achieving uniform heat flux distribution on the receiver surface.Taking a hundred-megawatt-scale solar power tower station as an example,the heliostat aiming strategy is optimized.Under typical spring equinox conditions,the peak heat flux density on the receiver surface is reduced from 1.94 MW/m2 with equatorial aiming to 1.01 MW/m2,improving uniformity by 53.29％while reducing the spillage factor by 0.86％.This ensures efficient and safe operation of the receiver while maintaining high in-terception efficiency.关键词
