太阳能发电关键参数的仿真与应用研究

Simulation and Application of Key Parameters in Solar Power Generation

为了量化影响太阳能发电关键因素光伏阵列的最佳倾角,利用光伏发电的基本原理,研究不同时间段太阳高度角随不同方位角的活动轨迹,计算当地倾斜面辐射总量,实现光伏系统安装倾角优选以减小光伏阵列间的相互遮挡影响,并编制了程序。在应用于陕西某地20万MW光伏发电项目的太阳能板安装和技术设计中取得了满意的效果。

In order to quantify the key factors that affect the solar power generation efficiency and determine the optimal tilt angle of the photovoltaic array,the active trajectories of the solar altitude angle with different azimuth angles in different time periods are analyzed and the total solar radiation amount of local inclined planes is calculated.Then,the optimal installation tilt angle of the photovoltaic system is obtained,which can reduce the mutual occlusion of the arrays.A calculation code is also provided.Satisfactory performance is achieved in its application in the installation and design of the solar panels in a 200 MW photovoltaic power generation project in Shaanxi Province.
