摘要

随着陆上风电在低风速区域的广泛应用，传统风电机组的叶片气动外形在低风速条件下的效率已不能满足发电需求。本研究提出了一种叶片气动外形改进方案，通过优化叶片的形状和调整气动性能，以提高低风速下的发电效率。针对低风速区域风电机组的工作环境，本文通过计算流体力学（CFD）模拟与风电机组实际工作数据分析，验证了改进后的叶片设计在低风速环境中的增益效果。改进后的叶片气动外形能够有效提高风电机组在低风速下的发电量，并提升其整体经济效益。本研究为风电行业在低风速区域的优化设计提供了新的思路和方法。

Abstract

With the widespread application of onshore wind power in low wind speed areas, the efficiency of the blade aerodynamic shape of traditional wind turbines under low wind speed conditions can no longer meet the power generation requirements. This study proposes an improvement scheme for the blade aerodynamic shape. By optimizing the blade shape and adjusting the aerodynamic performance, the power generation efficiency under low wind speeds is improved. Aiming at the working environment of wind turbines in low wind speed areas, this paper verifies the gain effect of the improved blade design in a low wind speed environment through computational fluid dynamics (CFD) simulation and analysis of the actual working data of wind turbines. The improved blade aerodynamic shape can effectively increase the power generation of wind turbines under low wind speeds and enhance their overall economic benefits. This study provides new ideas and methods for the optimized design of the wind power industry in low wind speed areas.
