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.
