摘要： 针对老旧风电场由于风电机组风轮和风资源未能很好匹配等原因导致的发电量不理想问题,提出一种基于加装叶尖小翼风电机组发电量提升方法,该方法在增加叶片扫掠面积的同时有效改善叶片的气动性能。通过加装叶尖小翼增加叶尖部分切向力,增加主轴扭矩从而提高风轮吸收功率,达到提升发电量的目的。基于风电场实际试验数据对提功增效效果进行分析,结果表明所提方法在满足安全性的前提下可有效提高机组输出功率,提升发电量。同时该方法成本低,展现了良好的性价比。

Abstract: Aiming at the problems of unsatisfactory power generation in old wind farms due to poor matching of wind turbines and wind resources, a method for increasing power generation of wind turbines based on the installation of small wing blades is proposed. This method improves the aerodynamic performance of blades effectively while increasing the sweep area of blades. By installing the tip winglet, the tangential force of the tip part is increased, and the main shaft torque is increased, thereby increasing the power absorption of the wind wheel and achieving the purpose of increasing the power generation. Based on the actual test data of wind farms, the effect of power improvement and efficiency is analyzed. The results show that the method proposed in this paper can effectively increase the output power of the unit and increase the generation capacity under the premise of meeting safety. At the same time, the method is low cost and shows a good cost performance, which has a good guiding significance for the research on the performance improvement technology of wind turbines in China.
