Resumen
Method and system for controlling wind farms (1) connected in series to an hvdc link (8), where each wind farm (1) is connected to a bus (3) which, in turn, is connected through a step-up transformer (6) to an ac/dc rectifier station (7) that evacuates the generated energy to an hvdc link (8), where the bus (3) is connected to a capacitor bank (5) and to an electronic converter ( 4), which also comprises a plurality of alternating current links (11) connecting the bars (3) to each other at least two to two, so that it is possible to equalize the powers injected by each ac/dc rectifier station (7) to the hvdc link (8) by modifying the frequency in the busbar (3) of each wind farm (1) so that said frequency increases proportionally to the voltage in said busbar (3).
