【摘要】 太阳辐照模型是工农业及建筑节能领域开发利用太阳能的基础,不同地理位置的地区,其水平面上所能接收到的太阳辐照度随着季节、纬度、经度以及海拔高度等条件的不同而变化。在建立太阳辐照模型的基础上,利用MATLAB仿真软件模拟了不同条件下的太阳辐照度,分析了辐照度随一年中的典型季节、纬度、经度及海拔高度的变化趋势。结果表明,太阳辐照度随不同季节发生明显变化,夏季辐照度高,冬季辐照度低;而随纬度、经度及海拔高度则变化较小,为太阳能的开发利用提供理论依据。更多还原

【Abstract】 Solar irradiance model is the basis for developing and utlizing solar energy in industries, agriculture and for building energy conservation field. Solar irradiance in different geographical areas received on the horizontal plane varies with the seasons,region latitude-longitude and altitude conditions. Solar irradiance model was proposed and simulated with the MATLAB simulation software under different conditions. The relations between the irradiance and the typical number of days, the latitude, longitude and altitude were studied. The results showed that solar irradiance changed siginificantiy with different number of days. Irradiance in summer was high while that winter was low. Irradiance with latitude-longitude and altitude did not change obviously. It will provide theoretical reference for developing and utilizing of solar energy.更多还原
