基于综合效率系数的光伏电站发电量估算方法
|
摘要
陕西省榆林地区拟建50 MW容量光伏电站,该光伏电站采用180 W(36)型单晶硅光伏电池和220 W(29)型多晶硅光伏电池作为组件,光伏组件架构采用固定式角度安装,单元方阵的最佳方位角确定为0°,最佳倾角选定35°、行距5 m。对电站发电量进行估算:将电站所在地纬度和其他影响发电量的因素设置为独立参数,确定相应纬度辐射量,然后根据其他因素得到综合效率系数,最后估算出年上网发电量。该估算方法可应用于光伏电站工程项目设计。
A 50 MW photovoltaic power station is proposed in Yulin, Shanxi province,The photovoltaic power station adopts the 180 W(36) single crystal silicon photovoltaic cells and 220 W(29) type polycrystalline silicon photovoltaic cells as module, the photovoltaic component architecture by the fixed slant installation, the unit square optimal azimuth angle of 0° and 35° is selected as the best Angle, spacing 5 m. Then the power generation of the power station is estimated: the latitude of the location of the power station and other factors affecting the power generation are set as independent parameters to determine the radiation amount of corresponding latitude, and then the comprehensive efficiency coefficient is obtained according to other factors. Finally the annual online power generation is estimated. The estimation method can be applied to the design of photovoltaic power station project.
