Abstract

In order to study the impact of complex mountainous terrain on the regional wind field of photovoltaic （PV） farms, an actual PV site is taken as the research object, and the complex terrain is quickly modeled based on Blender+GIS.Numerical simulation of computational fluid dynamics is carried out using ANSYS finite element software, and by setting two different calculation ranges, quantitatively determines the wind field characteristics of the complex mountainous terrain under different wind conditions as well as the wind speed correction coefficients that should be taken into account in the design of photovoltaic mounts.The results show that the distribution of the near-surface wind field in complex mountainous terrain is highly non-uniform.The maximum wind speed correction factor for the area in which each site is located occurs primarily when the wind is from the northwest （315°） and is generally consistent with the weather report data. The wind farm data obtained in the numerical simulation are applied Python automated processing, and finally the most unfavorable wind direction and the corresponding wind speed correction coefficient suggested values for the actual construction site are obtained.
