计及气象条件的光伏板最佳安装角度计算

针对固定武光伏板最佳安装角问题,提出了综合考虑安装角度、气象条件、太阳辐射总量等因素的光伏板表面接收辐射模型.利用修正后的Angstrom线性回归方程,对理想情况下的太阳辐射量进行了逐时计算.通过聚类分析和统计学方法,将天气分为五种类型,量化了各类型天气对辐射量的影响,并在年辐射总量的计算中应用蒙特卡洛方法对气象条件进行模拟.最终,利用文中模型,对华北某地的气象条件进行了统计分析,给出了不同安装角度下的光伏板表面接收年辐射总量和不同时间段内的光伏板最佳安装倾角.

Calculation of Optimal Installation Angle of PV Panel Considering Weather Condition

For the optimal installation angle problem of fixed photovoltaic panels,the paper proposes a comprehensive model considering mounting angle,weather conditions,total solar radiation and other factors,calculates the amount of solar radiation changing with time by modified Angstrom linear regression equation in ideal case.Using cluster analysis and statistical methods,the paper divides weather into five types,quantifies the impact of the various weather types on the radiation,and uses Monte Carlo method to simulate the meteorological conditions in the calculation of total annual radiation.Finally,with the proposed model,the paper carries out a statistical analysis of weather conditions in one place on the north China,gives the total radiation received by the photovoltaic panels＇surface with multiple installed angles and the best installed angles with different period.
