    摘要： A wind turbine and methods for controlling wind turbine thrust are disclosed. In one embodiment, the method includes measuring a tilt angle of a wind turbine in a loaded position using a measuring device. The wind turbine includes a tower, a nacelle mounted on the tower, a rotor coupled to the nacelle, and a plurality of rotor blades coupled to the rotor. The method further includes comparing the tilt angle to a predetermined tilt angle for the wind turbine and, if the tilt angle exceeds the predetermined tilt angle, adjusting a pitch of at least one of the plurality of rotor blades such that the tilt angle is less than or equal to the predetermined tilt angle.
