| Abstract: | Based on multi-body system dynamics and lift line aerodynamic model, considering dynamic stall and aeroelastic coupling of flexible back-swept blades, a wind turbine aeroelastic coupling model is established to study the effect of extreme operating gusts and duration of the gusts on the aerodynamic performance of a 5 MW back-swept wind turbines blades. The results show that extreme operating gusts have a great influence on aerodynamic characteristics, such as the flapwise root moment, power, angle of attack, lift coefficient and thrust. The research work has an important significance for wind turbine’s structural optimization and fatigue life design. |
