摘要：

为了对无太阳辐射观测的咸宁市进行并网光伏电站太阳能资源综合评价，拟采用水平面太阳辐射气候学推算方法和倾斜面辐射换算方法，即根据武汉站历史资料分月建立总辐射量和直接辐射量与日照百分率的推算方程推算出咸宁逐月太阳辐射各分量，分析其时间变化、资源丰度和稳定性，并基于Klein提出的散射辐射各向同性的假设，计算出该地不同倾斜面年总辐射量和最佳倾角。结果表明：咸宁地区近50 a（1961~2009年）水平面太阳总辐射年总量为4 0914 MJ/m2，该地区属于太阳能资源丰富区，该地辐射形式等级处于散射辐射较多(C)等级，且太阳能资源年变化稳定度较高。正南朝向斜面接受总辐射年总量最大的条件下其最佳倾角为18°，该倾角下斜面年总辐射量为4 2246 MJ/m2，比水平的值高出33%。设计容量为1 500 kWp的光伏阵列若按最佳倾角和方位角安装，每年可发电约132×106 kW·h。太阳辐射各分量的合理推算与多个评价指标的联合应用为光伏电站规划设计提供了科学依据，也为今后类似工作提供了样本。

Abstract:

In order to evaluate grid PV power station solar energy resources in Xianning which without solar radiation observation data,by plane solar radiation climatology computative method and slope surface radiation conversion method,that is,based on historical data of Wuhan station on establishing total amount and direct radiation quantity and the sunshine percentage calculation equation Xianning monthly solar radiation components was calculated,and their time change,resource abundance and stability were analyzed.Based on the scattering radiation isotropic hypothesis,the amount of radiation on tilted surface and the best angle were calculated.Results show that:In recent 50 years(1961~2009) total solar radiation amount in Xiannin region was 4 0914 MJ/m2.This area is a rich region of solar energy resources.The radiation level is C level which is more scattering radiation,and stable degree is higher.Optimum tilt angle in the conditions of the biggest total solar radiation amount of a year is 18°,in this angle the total amount of radiation is 4 2246 MJ/m2,33% higher than the horizontal plane.If it is installed by the best dip and azimuth,the designed capacity of the photovoltaic array 1 500 kWp annual power will generate 132×106 kW·h.The reasonable calculation and application of evaluation index of various components of solar radiation will provide a scientific basis for planning and design of photovoltaic power plants,and provided a sample of similar work in future
