摘要

The present invention relates to a method for the reduction of voltage fluctuations and flicker produced by wind farms of fixed speed asynchronous generators. The procedure consists of the regulation of the speed of one or more turbines of said park until obtaining, in each of these, an optimal position (phase) of the rotor, in such a way that the fluctuations of the power that they produce are subtracted to the fluctuations produced by the rest of the wind turbines. The present invention also relates to a device capable of providing an error signal to the control system of the wind turbines or the wind farm so that they vary their speed until their rotors are in their relative position suitable for the purpose pursued.
