Métodos de control de aerogeneradores para mejorar la producción de energía

Métodos de control de aerogeneradores para mejorar la producción de energía siguiendo una curva potencia vs. velocidad del generador (31 ) que comprende una zona nominal (39) donde se mantiene constante la potencia a su valor nominal, una primera zona sub-nominal (33), una segunda zona sub- nominal (35) donde se permite que tanto la velocidad del generador como la potencia aumenten/disminuyan en línea con la velocidad del viento y una tercera zona sub-nominal (37) entre la segunda zona sub-nominal (35) y la zona nominal (39) que comprende un primer segmento vertical (41 ) a una velocidad del generador Method of operation of a variable speed wind turbine (11) having control means for its regulation tracking a power vs. generator speed curve (31) comprising a nominal zone (39) where the power is kept constant at a nominal value, a first sub-nominal zone (33) where the generator speed is kept constant at its coupling value, a second sub-nominal zone (35) where both generator speed and power are allowed to increase/decrease in line with wind speed and a third sub-nominal zone (37) between the second sub-nominal zone (35) and the nominal zone (39) that comprises a first vertical segment (41) at a generator speed n r2 higher than the generator nominal speed n r1 and a second vertical segment (43) at the generator nominal speed n r1 connecting with the nominal zone (39), each of both segments (41, 43) to be followed in function of the wind speed changes for optimizing the energy production.
