| Abstract: | Based on the large-scale operation data of wind turbines, a method for modeling the output power of wind turbines based on mutual information analysis was proposed. Based on this model, the performance of wind turbines before and after the installation of vortex generators was evaluated. The calculation and verification results show that the model can better match the output power of the unit, and the addition of a vortex generator at the leading edge of the blade can effectively improve the generating performance of the unit and improve the wind turbine utilization. |
