SYSTEMS AND METHODS FOR CONTROLLING TOWER CLEARANCE IN A WIND TURBINE |
摘要 |
A wind turbine control system includes a detecting unit for adjusting a reference nodding moment of a wind turbine rotor based on at least one of an aerodynamic thrust on the wind turbine rotor and a speed of wind; a compensating unit for determining a physical nodding moment of the wind turbine rotor, comparing the physical nodding moment with the reference nodding moment, and using the comparison to compute a pitch angle command for at least one wind turbine blade; and a driving unit for changing a pitch of the at least one blade based on the pitch angle command to control the physical nodding moment of the wind turbine rotor. |
