摘　　要：综合考虑倾斜面太阳辐照度估算模型和实际组件转换效率估算模型,建立一个固定倾角下的组件发电功率模型,并提出一种以年功率最大为最优倾角设计原则的优化设计方法。基于武汉、南京和北京三地的大量数据对提出的方法进行验证和分析,结果显示该方法可为电站增加发电量,增大经济效益,且电站纬度越高,其发电量提升空间也越大。The estimation model of solar irradiance on inclined surface and the estimation model of conversion efficiency for actual module are comprehensively considered,the power generation model of PV module under a fixed tilt angle is established,and a kind of optimization design method with the annual maximum power as the optimal tilt angle design principle is proposed.Based on large amount of data from Wuhan,Nanjing and Beijing,the proposed method is verified and analyzed.The results show that the optimal design can improve power generation quantity and bring economic benefits for PV power plants,and the higher the latitude of the PV power station,the greater the improving space for power generation.
