    摘要： A method is provided for damping an oscillatory movement of a nacelle of a wind turbine. The nacelle is attached to a tower of the wind turbine. The method involves rotating the nacelle about a yawing axis with a yawing speed, the yawing axis being aligned with a longitudinal axis of the tower, changing the yawing speed, and coordinating the yawing speed with the oscillatory movement such that a torque resulting from the change of the yawing speed damps the oscillatory movement of the nacelle of the tower.

    摘要： A wind turbine has a Lidar device to sense wind conditions upstream of the wind turbine including wind speed, direction and turbulence. Signals from the Lidar are processed to detect an event which could give rise to low cycle fatigue loading on one or more components of the wind turbine. On detection the system controller takes the necessary evasive action depending on the nature and severity of the extreme condition detected. This may include a significant reduction in power generated through reduction in rotor speed or torque, complete shutdown of the generator and yawing of the nacelle and rotor in response to a change in wind direction.

    摘要： A method to individually optimize respective pitch angles of blades in a wind turbine. The method allows supplying (102) a modulation signal to modulate a pitch angle of the individual blade being optimized. The method further allows filtering (104) output power of the turbine subject to the modulating frequency to extract a power signal in a frequency spectrum including the modulating frequency. The extracted power signal and a demodulation signal are mixed (106) to generate a signal including a product of the extracted power signal and the demodulation signal. The generated signal is filtered (108) to remove the modulating frequency and extract a gradient signal effective to search a pitch angle estimate conducive to optimize output power of the turbine. The gradient signal may be integrated (110) to cause the gradient signal to converge towards an optimal pitch angle for the individual blade being optimized.

    摘要： The application describes a wind turbine having a control method and controller for performing predictive control of a wind turbine generator. Based on the measured instantaneous wind speed, it is known to provide control signals to a wind turbine in order to control the pitch of the wind turbine rotor blades and the speed of the generator. However, it is difficult using instantaneous wind speed measurements to achieve smooth control, due to finite response speeds of the associated electro-mechanical systems, as well as the constantly changing control system inputs. The predictive control system described in the application assumes a model of generator speed based on the values of the incident wind speed v(t) and the values of a control signal u(t) output to the wind turbine in a feed forward loop. Here, the control signal can be for one or more of controlling either the power setting of the generator, or the pitch angle of the rotor blades. The predictive controller uses a rolling time series of values for v(t) and u(t) and based on a predicted response of the generator speed w(t) optimizes the time series control signal u(t). The predicted response of the generator speed w(t) is based on model, that can be refined in real time as the wind turbine operates.
