摘　　要：[Objective] The aim was to analyze characters of solar energy in photo- voltaic power stations in Shandong Province. [Method] The models of total solar radiation and scattered radiation were determined, and solar energy resources in pho-tovoltaic power stations were evaluated based on illumination in horizontal plane and cloud data in 123 counties or cities and observed information in Jinan, Fushan and Juxian in 1988-2008. [Result] Solar energy in northern regions in Shandong proved most abundant, which is suitable for photovoltaic power generation; the optimal angle of tilt of photovoltaic array was at 35°, decreasing by 2°-3° compared with local latitude. Total solar radiation received by the slope with optimal angle of tilt exceeded 1 600 kw.h/（m2.a）, increasing by 16% compared with horizontal planes. The maximal irradiance concluded by WRF in different regions tended to be volatile in 1 020-1 060 W/m2. [Conclusion] The research provides references for construction of photovoltaic power stations in Shandong Province.[目的]分析山东省光伏电站太阳能资源特征。[方法]利用1988～2008年山东省123个县市水平面日照、云量观测资料和年济南、福山、莒县辐射观测资料,确定太阳总辐射、散射辐射计算模型,并进行光伏电站太阳能资源评估。[结果]山东半岛北部、鲁北地区为太阳能资源很丰富区,较适宜光伏发电;太阳能光伏阵列的最佳倾角在35°左右,与当地纬度相比减小2°～3°;年最佳倾角坡面接收的太阳总辐射量在1600kW.h/(m2.a)以上,可比当地水平面上多接受16%左右的总辐射量。用WRF数值模式获得各地最大辐照度在1020-1060W/m2之间。[结论]该研究为山东省光伏电站的建设提供了基础资料。
