摘要
在统一其他变量不变的条件下,研究了太阳能光伏阵列的排布方式对光伏板温度的影响。以徐州地区某光伏电站为原型,采用数值模拟的方法,建立单块光伏组件在空气流场中的模型并进行模拟,使用统计学的方法对实验值与模拟值进行比较,验证了模型的准确性。对光伏单板和光伏阵列进行数值分析,发现背风侧"死水区"形成较大的涡流,旋涡大小随着风向逐渐减小。改变光伏板前后间距及左右间距进行优化,在徐州地区,建议使用5.4 m的前后板间距、1.6 m的左右板间距作为设计参考值。
Under the condition of unifying other variables,this paper studies the influence of the arrangement of solar photovoltaic arrays on the temperature of photovoltaic panels.With a photovoltaic power station in Xuzhou area as a prototype,the numerical simulation method is used to establish a model of the monolithic photovoltaic module in the air flow field and simulate it.The statistical method is adopted to compare the experimental value with the simulated value to verify the accuracy of the model.Numerical analysis of photovoltaic veneers and photovoltaic arrays have revealed that the"Dead water zone"on the leeward side has formed a large eddy current,and the vortex size gradually has decreased with the wind direction.In this paper,the front and back spacing and left and right spacing of photovoltaic panels are changed to optimize the distribution of PV squares.In the Xuzhou area,it is recommended to use the front and rear plate spacing of 5.4 m and the left and right plate spacing of 1.6 m as design reference values.
