Resumen
The invention describes a method for controlling the voltage and frequency in an isolated network, where the isolated network comprises a busbar (5) that receives energy from at least one wind turbine (1) and evacuates it by means of a rectifier (2) to a dc transmission link (4), and where the busbar (5) is connected to a capacitor bank (6). The method makes it possible to keep constant the magnitude and frequency of the voltage in the busbar (5) if the direct component d (9) and quadrature q (10) of the voltage vector (11) in the busbar (5) are kept constant. . This is achieved by controlling the reactive injected in the busbar (5) and, in case the rectifier (2) is controlled, controlling the firing angle of the thyristors.
