摘要
利用实地观测站及参证气象站地面气象观测资料,对宁夏太阳山地区水平面太阳总辐射年、季、逐日、逐时变化特征、直接辐射、散射辐射、斜面辐射分布特征进行分析;通过参证气象站代表年与季节相关方程订正出太阳山地区代表年并对其进行年际变化、季节变化特征分析。结果表明:太阳山地区实测观测年总辐射为1712.3 kWh/m^2,年均直射比为0.61,光伏发电最佳倾角为37°,400 W/m^2以上辐照度区间占比77%,有利于光伏发电;近30年年总辐射在1628.6~1905.1 kWh/m^2之间,总体呈明显减少趋势,四季的总辐射差异较大,夏季最大,冬季最小;代表年总辐射为1716.4 kWh/m^2。
Using the observation station data and partial meteorology station data,the characteristics of annual,seasonal,daily,and hourly variation of the total solar radiation on horizontal plane in Taiyangshan region of Ningxia,also the distribution characteristics of direct radiation,scattered radiation,and total radiation on inclined surface are analyzed in this paper. The representative year in Taiyangshan region is revised by the representative year of Yinchuan and the seasonal correlation equation,and interannual and seasonal variation is also analyzed. The results show that actual measured annual total radiation in Taiyangshan region is 1712.3 kWh/m^2,the average annual direct ratio is 0.61,the optimum tilt angle of photovoltaic power generation is 37°. The irradiance interval above 400 W/m^2 accounts for 77%,which is conducive to photovoltaic power generation. In the past 30 years,the annual total radiation is between 1628.6-1905.1 kWh/m^2,and the overall trend is obviously decreasing. The total radiation difference in the four seasons is large,the largest in summer and the smallest in winter;the representative year is 1716.4 kWh/m^2.
