摘要： Embodiments of the invention generally relate to wind turbine generators, and more specifically to improving power production in wind turbine generators. A rotor plane of the wind turbine may be divided into a plurality of sections. A characteristic of wind associated with each section may be determined. An optimal pitch angle may be determined for each section based on the associated wind characteristic. A pitch controller may adjust the pitch angle of a blade to the optimal pitch angle as the blade sweeps through the section.

摘要： The invention relates to a method of controlling a wind turbine comprising blades attached to a rotor hub for rotation in a rotor plane and a control system for individually pitching the blades relative to the hub. The method comprises the steps of dividing the rotor plane into a number of sectors, determining the individual sectors for each blade during the rotation by means of an azimuth angle sensor, and obtaining blade sensor data from a blade sensor on an individual blade relating to a sector,and comparing the obtained data with data relating to the same sector and representing blade sensor data on other blades. Hereby an event may be detected for individual sectors of the rotor plane. When an event is detected in a given sector,an individual pitch contribution t is determined in the sector, and the blades are then pitched according to this individual pitch contribution for that given sector at least partly during passage of the sector. The invention further relates to a wind turbine comprising a control system for individually pitching the blades relative to the hub according to the above mentioned control method. (FIGURE 1)

摘要： 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.

摘要： 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.

摘要： 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 .
