Abstract
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.

Method for controlling pitch angle 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 measuring at least one parameter related to a blade state of the first blade and communicating the at least one measured parameter to a controller adapted to determine a first blade state, and
- the second blade comprise at least one second sensor system measuring at least one parameter related to a blade state of the second blade and communicating the at least one measured parameter to the controller adapted to determine a second blade state,
- wherein the first blade state is defined by the controller based on the at least one measured parameter related to the first blade state,
- wherein the second blade state is defined by the controller based on the at least one measured parameter related to the second blade state, and
- wherein the pitch angle of the second blade is adjusted by the controller in advance of the arrival of the second blade in a point in the rotor plane, at least based on the first blade state determined based on the at least one parameter related to the first blade state measured in said point and further based on the blade state of the second blade.
Apparatus for controlling pitch angle of a blade on a wind turbine, having at least a first blade and a second blade, said apparatus comprising,
- a first blade sensor measuring at least one parameter related to a blade state of the first blade and communicating the at least one measured parameter to a controller adapted to determine a first blade state of the first blade,
- a second blade sensor measuring at least one parameter related to a blade state of the second blade and communicating the at least one measured parameter to the controller adapted to determine a second blade state of the second blade,
- wherein the controller is adapted to define the first blade state based on the at least one measured parameter related to the first blade state,
- wherein the controller is adapted to define the second blade state based on the at least one measured parameter related to the second blade state, and
- wherein the controller is adapted to control the pitch angle in advance of the arrival of the second blade in a point in the rotor plane, at least based on the first blade state determined based on the at least one parameter related to the first blade state measured in said point and further based on the blade state of the first blade and on the blade state of the second blade.
