摘　　要：山地光伏发电系统建设环境复杂,其发电量受外部环境多维度的影响,为更深入地探究实际发电量与外部环境的关系,提出将三维建模与光辐射模型相结合,完成光伏系统发电量评估,为光伏场站的建设提供理论依据。首先,将地理信息系统Meteonorm的相关太阳能光辐射遥感数据导入传统Hay光辐射模型,再以现场地质勘探情况为基础进行高程点设置,进而构建精准度较高的三维地形模型并完成相关光辐射资源计算,最后通过对比光伏组件的方位角、倾斜角、光辐射散射变化来完成光伏系统最佳布置方案。模拟结果表明,倾角与方位角的轻微变化对光伏系统的影响较小,光伏组件高度调整导致的光辐射反射与漫射变化对整体发电量影响较大。Due to the complex mountainous construction environment,solar panel working efficiency is affected by multiple dimensions of the external environment.For research the relationship between generated electricity and environment factors,a method used with combine three-dimensional modeling with radiation models to assess generated electricity in solar system.Firstly,by importing the relevant solar radiation data from a data system,Meteonorm,into the traditional Hay radiation model to construct a highly accurate model to process radiation resource calculation.Finally by comparing devices factor change,such as azimuth angle,tilt angle,and light radiation scattering,to assess solar system.The simulation results indicate that slight changes in tilt and azimuth have a small impact on the photovoltaic system,while changes in radiation reflection and diffusion caused by height adjustment of photovoltaic modules have a significant impact on the overall power generation.
