Abstract

In order to study the influence of wing fence installation position on the aerodynamic performance of wind turbines, a 1.5 MW wind turbine is taken as the research object. Considering the blade spreading position and circumferential position, 13 models including the original blade are calculated and analyzed under different conditions through numerical simulation. The results show that not all models can improve the blade power, which also explains the necessity of exploring the optimal installation position of wing fence. Compared with the installation of wing fence on the pressure surface and both sides at the same time, the installation of wing fence only on the suction surface can more effectively inhibit the spreading flow separation, make the separation point move back and improve the aerodynamic performance of the blade. Among them, at the wind speed of 9.9 m/s, the performance of model 5 （the wing fence only on the suction surface at the spreading position 8 m from the blade root） is the best, which effectively inhibits the flow separation and improves the power by 1.876%, which is 0.541% higher than the model 4 with wing fence installed on both sides at the same time.
