【摘要】：在建筑能耗模拟与太阳能建筑系统设计中,逐时的太阳直射和散射气象数据是最重要的基本参数。由于中国辐射观测数据的缺失,逐时直射和散射数据很难获得。很多学者对此进行了研究,提出了数十种直散分离模型。采用北京地区2009年—2011年3年太阳总辐射和散射实测数据,选取Erbs模型、Orglill模型、清华大学随机气象模型、宇田川光弘模型、张晴原模型5个代表性的直散分离模型进行计算验证,分析比较了实测数据和计算数据之间的相关系数R、均方根误差RMSE和相对误差RE,得出晴空指数Kt可以作为最主要的影响因子,Erbs模型预测散射的准确率最高,其次为张晴原模型和Orglill and Hollands模型。
[Abstract]:In building energy consumption simulation and solar building system design, hourly direct solar radiation and scattering meteorological data are the most important basic parameters, due to the absence of radiation observation data in China. It is very difficult to obtain time-by-time direct and scattering data, which has been studied by many scholars. In this paper, dozens of direct dispersion models are put forward. The Erbs model is selected by using the measured data of total solar radiation and solar scattering from 2009 to 2011 in Beijing area. The random meteorological model of Tsinghua University, Yutian Chuanghuang model and Zhang Qingyuan model are calculated and verified by 5 representative direct dispersion separation models. The correlation coefficient R between measured data and calculated data is analyzed and compared. The root-mean-square error (RMSE) and the relative error (RER) show that the clear sky index Kt can be used as the most important factor to predict the scattering accuracy. The second is Zhang Qingyuan model and Orglill and Hollands model.
