The Study Of The Influence Factors On Photovoltaic Modules Wind Tunnel Test And Numerical Simulation

Solar photovoltaic power station is located in the desert gobi or the terrain open land ingeneral. In this open land that the wind load plays an important role in the design of thebattery components support and foundation. The selection values and shape coefficients of thewind load has a direct effect on the safety of the support and foundation. So this article isbased on wind tunnel test, mainly research the variation of the wind load shape coefficientalong with different wind angle, inclination angle，height，spacing，location of photovoltaicmodules support. Adopts numerical simulation to study the characteristic of photovoltaicmodules support cell array.A single piece of photovoltaic modules support unit which scale ratio is1/10was usedfor the simulation experiment of the wind characteristics. Under three different wind speedwhich is5m/s,10m/s,15m/s，researching the varying pattern of the average wind speedalong with the different heigh under having panels and no panels.Selecting a single piece of photovoltaic modules support unit which scale ratio is1/20tostudy the effect of wind angle and inclination angle on the wind load shape coefficient ofphotovoltaic modules support unit by changing the size of the wind angle and inclinationangle.Take two pieces and three rows of three columns of photovoltaic modules support unitwhich are the same scale ratio, researching the effect of model spacing and location on thewind load shape coefficient of photovoltaic modules support unit.Adopts numerical simulation to study the effect of photovoltaic modules support cellarray. Parameterize the wind direction, inclination angle, spacing, location of photovoltaicmodules support. Get the computational formula of surface wind load for a single piece ofphotovoltaic modules support unit in the photovoltaic modules support cell array.
