Abstract

Abstract

Photovoltaic（PV） power generation， recognized as a clean energy source， has become a crucial component of the global energy transition. In the structural design of PV arrays， wind load serves as the primary controlling factor. The wind load shape coefficients， influenced by a complex interplay of various aerodynamic interference factors， directly determine the structural safety and economic feasibility of the PV system. To explore the influencing factors of the shape coefficients of modules in ultra-large PV arrays， this study takes an actual fishery-PV complementary power generation project as a case study. This paper investigated the influence of terrain shading and wind direction angle on the shape coefficients using ANSYS Fluent software. The results show that under conditions of complete terrain sheltering， the influence of wind direction angle can be neglected， and a uniform shape coefficient value of 0.3 can be adopted for all PV modules. Conversely， without terrain shielding， the wind direction angle must be considered， necessitating a shape coefficient of 1.1 for the modules within the array.
