A method and device for controlling output power in a primary frequency modulation process of a wind turbine are provided by the present disclosure. The method includes predicting a rotational speed of the wind turbine; determining frequency modulation remaining time based on the predicted rotational speed, the frequency modulation remaining time being time for which the wind turbine is able to continue to output frequency modulation power as the output power used for the primary frequency modulation without affecting a recovery of the wind turbine after the primary frequency modulation; controlling the output power based on the determined frequency modulation remaining time.

Method and device for controlling output power of a wind turbine

The invention relates to control of a wind turbine comprising a plurality of multi-axial accelerometers mounted at different positions in the nacelle and/or in a top portion of the tower. The position and orientation of each accelerometer as mounted is obtained, accelerations in at least two different directions by each accelerometer are measured during operation of the wind turbine. From a number of predetermined mode shapes for the movement of the wind turbine is then determined an absolute position of at least one of the accelerometers during operation of the wind turbine based on the measured accelerations, the mount position and orientation of each accelerometer and the pre-determined mode shapes. Hereby a more precise absolute position during operation is obtained which can be used in the controlling of the turbine.

Control of a wind turbine comprising multi-axial accelerometers

The present disclosure relates to a control of a wind turbine in connection with power boosting or fast increase of active power production. A boost command is received () and based on the current operational state and the boost level a predicted control trajectory is calculated using a model predictive control (MPC) routine (). The wind turbine is controlled using the calculated control trajectory during the power boost ().

Power boost of a wind turbine using model predictive control

The invention regards an apparatus or method for controlling the profile of a blade on a wind turbine having at least a first blade and a second blade, the first blade comprise at least one first sensor system adapted to determine a first blade state and the second blade comprise at least one second sensor system adapted to determine a second blade state, wherein the profile of the second blade is controlled based on the determined first blade state and the determined second blade state.
