Resumen
Method for the distributed control of the frequency in a wind farm, where the park comprises wind turbines (11) connected to a line (24) connected to a busbar (3), where the bar (3) is connected by a transformer (6) with a diode AC/DC rectifier station (7) connected to a DC link (8) that evacuates through an inverter station (9) the energy generated by the wind farm (1) to the electricity network (10). Each wind turbine (11) includes an internal converter (110) comprising an inverter (113) and a capacitor (C) connected between the output of said inverter (113) and a transformer (23) output elevator of the wind turbine (11). The method comprises equalizing the frequencies generated by each wind turbine (11) by controlling the quadrature component of the current (ikq) at the output of the inverter (113), performing said control acting on the internal voltages of the inverter (113).
