Abstract
With the development of low wind speed wind farm,the low wind speed horizontal-axis wind turbine (HAWT) is faced to the increasing large rotor and changeable wind condition.To improve the cost effectiveness of energy,weight-reduction techniques are widely used for large scaled blade.This results in lighter and more flexible rotor blades.It makes sense to develop a more accurate fluid solid interaction (FSI) model.The changeable wind condition leads to longer operation under yawed condition.In this study,a load control strategy is introduced by applying a nonlinear FSI model.The nonlinear FSI model has been developed by coupling a geometrically exact beam (GEB) with a free-vortex wake (FVW) model.The results demonstrate that this load control strategy can decrease the load fluctuation efficiently without a complex control system and additional sensors.关键词
