Abstract

Taking the three-span and five-row photovoltaic array of Guodian Investment Jiangsu Yancheng Flexible Photovoltaic Demonstration Base as the research object, the distribution characteristics and correlation of fluctuating wind loads in three-dimensional space were compared and analyzed based on wind tunnel tests, synchronously recording the pressure on the upper and lower surfaces. A regional division model for the correlation of flexible photovoltaic surfaces was established, revealing the variation of fluctuating wind loads in three-dimensional space and the coupling effects between the wind components on flexible photovoltaic surfaces. It is found that the upper edge of the flexible photovoltaic surface along the vertical direction is weakly correlated, while it become strongly correlated on the lower edge. The interference of horizontal cross array significantly affect the correlation of fluctuating wind pressure at the connection area of flexible photovoltaic array panels, and the first row of photovoltaic arrays is most severely affected by inter row interference; The correlation area between the overall resistance coefficient and surface fluctuating wind pressure shows a weak-strong-weak distribution on the flexible photovoltaic surface, and there is a significant coupling effect between the surface resistance and the transverse bending moment. The array interference enhances the coupling area in [0 °, 45 °] and [150 °, 180 °], and weakens the area in [45 °,150 °].
