为准确评估作用于光伏方阵上的风荷载，并进而确定跟踪支架推杆轴力，在对比分析日本规范和中国规范的基础上，结合风洞实验研究成果，提出了一种新的光伏方阵风压分布模型。新模型认为作用于光伏方阵上的风压具有不均匀性，且大致呈梯形分布。新模型的提出将为光伏结构精细化设计以及确定跟踪支架推杆轴力提供参考。

In order to exactly evaluate wind load on a photovoltaic array and determine the actuator axial force of tracking systems, a new wind load distribution model of photovoltaic array was proposed on the basis of the comparison between Japanese code and Chinese code, combined with the results of wind tunnel experiments. In detail, the wind pressures on the photovoltaic array had inhomogeneity, but roughly in trapezoidal distribution. The proposed model could provid a reference for the fine design of the photovoltaic structure as well as determination of the actuator axial force.
