Method of operation of a variable speed wind turbine (11) comprising control means for a standard regulation tracking a power vs. generator speed curve (21) that also uses an alternative regulation for optimizing the energy production along determinate time periods Tb for compensating previous energy losses at a higher power Pb than the power determined by said standard regulation, said alternative regulation being based on a continuous calculation of the accumulated lost energy ALE as the energy lost with respect to the maximum allowed energy production according to the standard regulation and on a setting of said higher power Pb and a setting of the duration of said time periods Tb being compatible with wind turbine electrical or mechanical limitations. The invención also refers to a wind turbine controlled by said method.
Method of operation of a variable speed wind turbine (11) comprising control means for a standard regulation tracking a power vs. generator speed curve (21) having a first sub-nominal zone (23) where the generator speed is kept constant at its coupling value, a second sub-nominal zone (25) where both generator speed and power are allowed to increase/decrease in line with wind speed, a third sub-nominal zone (27) where the generator speed is kept constant at a nominal value and a nominal zone (29) where the power is kept constant at a nominal value Pn, characterized in that an alternative regulation at a higher power Pb than the power determined by said standard regulation for optimizing the energy production is used along determinate time periods Tb for compensating previous energy losses.
