ABSTRACT:
A method for preventing mechanical oscillation in a wind power plant includes determining wind speed, controlling a generator of the power plant with speed control when the wind speed is below a predefined limit to maintain the rotation speed of the generator below a predefined first limit, detecting the increase of wind speed above the predefined limit, controlling the electric drive of the wind power plant generator to torque control by using a predefined crossover torque in response to the wind speed increasing above a predefined limit, maintaining the crossover torque as the reference torque for the electric drive until the rotation speed of the generator has increased above a predefined second limit, and controlling the electric drive of the wind power plant generator with torque control while the rotation speed of the generator remains above the predefined second limit.
