摘要
利用总辐射-散射辐射模式BRL,对BSRN香河站的逐小时总辐射资料进行直散分离,以验证BRL的直接辐射模拟能力。同时,检验局地调优对直散分离的影响。统计分析结果表明,BRL的直接辐射模拟精度在晴空下最高。经过参数优化后,直接辐射模拟误差显著减小。直散分离模式的局地寻优在光热电站资源评价中具有重要的工程应用价值。
To investigate the direct/diffuse decomposition of global radiation,global-to-diffuse model BRL was used to separate hourly global radiation at BSRN Xianghe station into direct and diffuse radiation elements.The results show that BRL performs best under clear-sky conditions,and tuning empirical coefficients of BRL optimally with local data largely decreases the overall modeling errors of direct radiation.Local tuning of global-to-diffuse model is a key procedure for solar resource assessment of a concentrating solar power plant.
