Controlling wind turbine pitch based on position data from position positioning sensor

Abstract

A method for controlling pitching of at least one rotor blade of a wind turbine includes receiving, via one or more position localization sensors, the position data relating to the at least one rotor blade of the wind turbine. Further, the method includes determining, via a controller, a blade deflection signal of the at least one rotor blade based on the position data. Moreover, the method includes determining, via a computer-implemented model stored in the controller, a pitch command for the at least one rotor blade as a function of the blade deflection signal and an azimuth angle of the at least one rotor blade.

Description

technical field [0001] The present disclosure relates generally to wind turbines, and more particularly to systems and methods for controlling pitch and / or pitch bias of a wind turbine using position data from position location sensors, such as real-time kinematic (RTK) sensors . Background technique [0002] Wind power is considered to be one of the cleanest, most environmentally friendly energy sources currently available, and in this regard, wind turbines have received increasing attention. A modern wind turbine typically includes a tower, generator, gearbox, nacelle, and one or more rotor blades. The rotor blades use known airfoil principles to capture kinetic energy from the wind and transmit the kinetic energy through rotational energy so that the rotor blades are coupled to the gearbox or directly to the The shaft of the generator turns. The generator then converts the mechanical energy into electrical energy that can be deployed to the utility grid. Such an arran...

However, these tools / methods cannot be used in offshore wind turbines due to physical constraints (e.g. offshore wind turbines are installed offshore where there is no surrounding assembly location)
