晴天太阳辐射模型的优化计算

AN OPTIMIZED CLEAR-DAY SOLAR RADIATION MODEL

对几种最常用的晴天太阳辐射模型进行对比计算研究 ,通过实验验证 ,第一种模型较符合实测值 ,编制了利用了该种模型计算任何地方任何一天的任何一段时间 (包括整个白天时间段 )内水平表面或朝南倾斜表面 (包括竖直表面 )上的太阳辐射能的计算程序软件 ,理论计算与实验值均在 5 %以内 ,完全能满足一般太阳能工程和科学研究的需要。

This paper presents the calculated results of several clear-day solar radiation models in wide application. A useful software to computate clear-day solar radiation on horizontal plane or slope plane (including vertical plane) at any place and any time span is also developed. The experiments show that the calculated results of model presents the better agreement with the measured data over the various time spans than the other models with relative error less than 5%, which is accurate enough for solar energy engineering design and research.
