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 10):
Control method according to  claim 5 , wherein the power optimization algorithm based on attaining the optimal value of an efficiency function f(\u03b8 *) obtained from the aerodynamic power model for each wind turbine comprises the following stages:\n checking and adapting by low-pass filtering of the integrity of the parameters obtained from the hardware ( 21 ) of the wind turbine ( 1 ) with respect to some preset ranges based on its particular characteristics. \n determining the efficiency function of the wind turbine ( 1 ) by calculating the ratio between the obtained generated power and the theoretically producible power calculated on the basis of the particular characteristics of the wind turbine ( 1 ). \n high-pass filtering of the efficiency function and demodulation of the obtained signal \n determining the gradient signal by multiplying the signal obtained from the previous step by the actual deviation value of the nacelle ( 4 ) and low-pass filtering the resulting signal \n accumulation of the value of the gradient signal in a variable that integrates the previous steps to secure a stabilized deviation value with respect of a preset value \n attaining the real deviation of the nacelle ( 4 ) with respect of the wind direction.
