Abstract:
Control system to prevent wind turbine misalignment situations employing mathematical algorithms implemented in the wind turbine controller. Different optimization algorithms have been analyzed getting results that yaw the nacelle of the wind turbine to positions that would maximize the efficiency function. Control system for detecting and preventing wind turbine misalignment situations that comprises a parameters acquisition unit that relates the wind direction with the deviation of the wind turbine nacelle, a wind turbine efficiency function calculation unit and a deviation comparison unit of the nacelle.

Claim (Index 1):
Control system for preventing misalignment situations of a horizontal axis wind turbine ( 1 ) equipped with a\n yaw system for the nacelle ( 4 ) for yawing with respect to the wind direction comprising an acquisition unit ( 8 ) that retrieves values of parameters that relate the wind direction (\u03b3) with a real deviation (\u03b1) of the wind turbine nacelle ( 4 ) by using the hardware already existing in the wind turbine ( 1 ), a calculation unit ( 9 ) of an efficiency function y=f(\u03b8) of the wind turbine and a comparison unit ( 10 ) for the deviation of the nacelle ( 4 ) characterized in that, being general automatic, installed in any location and requiring no extra measuring devices in addition to the ones already existing therein, (speed measurement sensors, wind direction measurement, power measurement and rotor rotation measurement), wherein said control system can detect and prevent misalignment situations of the nacelles in wind turbine implementing an optimization algorithm of numerical analysis of the efficiency function y=f(\u03b8) that maximizes the wind turbine efficiency, where \u03b8 * is the optimal alignment, that incorporates a filtering stage to attenuate low frequencies (k/s) of the components that generate the wind and meteorological characteristics and high frequencies (s/s+h) of the components of the wind turbine and characterized in that through said algorithm, commands are generated to permit the yaw system to orient the nacelle ( 4 ) of the wind turbine ( 1 ) toward positions that would maximize the efficiency function.
