FLOATING VERTICAL OFFSHORE WIND TURBINE WITH COMPENSATION SYSTEM AND METHOD TO PREVENT THE OVERTURNING OF SAID FLOATING WIND TURBINE

Vertical axis floating offshore wind-powered generator (100) comprising a wind turbine (1) arranged on a floating platform (2), and a method for stabilizing the floating platform (2) of said wind-powered generator (100). The wind turbine (1) comprises a plurality of blades (3) rotating about a vertical shaft (4), each blade (3) being attached to the vertical shaft (4) through at least one attachment arm (5). The floating wind-powered generator (100) also comprises a compensation system which reduces a bending moment transferred to the floating platform (2) as a result of the force exerted by the wind on the blades (3). The compensation system comprises at least one compensating device (6) associated with a blade (3), each compensating device (6) being arranged in an attachment arm (5). Each compensating device (6) comprises a moving element (6.1) which is configured for redirecting a surrounding air enveloping the wind turbine (1) and which generates, by way of reaction, a force causing a compensation moment on the floating platform (2) which counteracts the bending moment generated by the force exerted by the wind on the blades (3), thereby successfully increasing the stability of the floating platform (2).
