摘要
漂浮式光伏系统覆盖水面大,浮体、马道形状复杂,流体流动速度快、流动复杂,采用传统的经验公式方法计算受力可能存在一定误差。为此,基于孟加拉博多河342.8 MW光伏项目,采用计算流体力学方法计算受力,通过风、流和风流耦合工况下的实际尺度模型CFD计算模拟,计算了风速25 m/s、流速3 m/s下浮体系统的受力,预报了漂浮式光伏系统方阵的整体受力情况。
Floating photovoltaic system covers a large water surface,it has the characteristics of complex of the shape of floating body and raceway,high fluid flow velocity and complex flow.There may be some errors when the traditional empirical formula is used to calculate the force.Therefore,based on the 342.8 MW project of Bodo River in Bangladesh,thecomputational fluid dynamics(CFD)method is used to simulate the actual scale model CFD under wind,flow and wind flow coupling conditions to calculate the forces on the floating body system under the wind speed of 25 m/s and the velocity of 3 m/s.The overall force situation of the floating photovoltaic system array is predicted.
