Abstract: The present invention relates to pitch actuation of pitch-adjustable rotor blades of a three-bladed wind turbine in a situation where one blade load sensor is unavailable. Based on blade load signals (L1, L2, L3) and an availability signal (v1, v2, v3) for each of the blade load signals, combined load signals are constructed based on the available blade load signals. The combined load signals are determined based on application of a high pass filter to the blade load signals and a transform (T1) of the blade load signals to an intermediate coordinate frame, wherein, in the transform, the unavailable blade load signal is replaced with an estimated signal. A control action (CA) is performed using the combined load signals, and the resulting pitch modification signals (Δθ1, Δθ2, Δθ3) are applied to the pitch actuator.

Abstract: This invention relates to a method of controlling a wind turbine comprising a tower supporting a rotor comprising a plurality of pitch-adjustable rotor blades. The method comprises obtaining a movement signal indicative of a vibrational movement of the tower. An actuator signal is then determined based on the movement signal, the actuator signal being determined to produce a desired force to counteract the vibrational movement of the tower. A pitch reference offset signal for each one of the plurality of pitch-adjustable rotor blades is then determined based on the actuator signal. An integration is then applied to the pitch reference offset signals to determine modified pitch reference offset signals based on the integrated pitch reference offset signals. A pitch signal for each one of the plurality of pitch-adjustable rotor blades is the determined based on the modified pitch reference offset signals, the pitch signals being arranged to adjust the pitch-adjustable rotor blades to provide the force that counteracts the vibrational movement of the tower.

Abstract: A method for controlling a wind turbine is disclosed. The wind turbine comprises a set of wind turbine blades (1), each wind turbine blade (1) being provided with profile changing means (2, 4) being configured to be in an activated state in which it changes an aerodynamic profile of the wind turbine blade (1) and in a de-activated state in which the aerodynamic profile of the wind turbine blade (1) is unchanged. The profile changing means could be in the form of air deflectors (2) or air outlets (4). Upon deciding activation of the profile changing means (2, 4), an expected impact, P, on power output of the wind turbine as a result of the decided activation of the profile changing means (2, 4), is estimated. A new reference power output, Pref,New, is provided, taking the estimated impact, P, into account. The profile changing means (2, 4) is activated, and the wind turbine is operated in accordance with P ref,New .

Abstract: The present invention relates to control of a wind turbine where nacelle vibration is reduced by use of blade pitching. The nacelle vibrations are reduced based on a position signal of the nacelle. A pitch signal is determined based on the position signal and applied to the pitch-adjustable rotor blades in order to reduce nacelle vibration.

Abstract: The present invention relates to control of the power output of wind turbine generator that operates in derated mode to generate a produced power output level lower than an available power level. A pitch system 48 sets the blade pitch of a rotor to a pitch value based on the received power reference signal 40. A power system 43 controls the produced power output power level of the wind turbine to the requested power output level. Moreover, the blade pitch of the rotor is further controlled by a pitch feedback control loop 47 that modifies the pitch value based on a difference between the produced power output level 46 and the requested power output level 40.

Abstract: A method and associated control arrangement are disclosed for controlling a de-rated power output of a wind turbine generator, where the wind turbine generator is associated with a predetermined power ramp rate upper limit and operating with a de-rated rotor speed. The method includes ramping the power output from an initial power level to a target power level during a ramping interval. During a first portion of the ramping interval, the power output is ramped at a first power ramp rate less than the power ramp rate upper limit. The method further includes ramping the rotor speed to a predetermined rotor speed value contemporaneously with ramping the power output during the first portion of the ramping interval. The first power ramp rate is determined such that a difference between the power output and the target power level is monotonically decreasing during the entirety of the ramping interval.
