A floating platform for supporting generators of power derived from the wind, the waves and ocean currents, adopting an approximately disc-shaped general configuration with a circular or polygonal perimeter, which optimises its size and therefore minimises substantially its weight and likewise its production costs, as well as other associated complexities; which eliminates the possibility of entering into resonance with the movement of the ocean waves and thus not damaging the equipment installed, not overturning, and not surpassing the maximum list acceptable for wind power generators, nor wave power generators, nor ocean current generators; and which withstands the waves of the greatest size possible, all due to a ratio between its depth or height (13) and the diameter (14) thereof of between 0.06 and 0.35.

A blade pitch controller for a wind turbine includes a nominal control system and a tower feedback loop. The tower feedback loop includes a filtering system. The filtering system is arranged to control wind turbine blade pitch so as to provide additional effective stiffness to the wind turbine in response to motion of the wind turbine which is above a filter frequency of the filtering system.

The present invention relates to a solution for a floating wind platform made of reinforced concrete for mass production, characterized by a geometric design providing a hydrostatic natural prestressing to the concrete, causing it to work under compression. The structural response of the platform for working in the most effective mode is improved, and the occurrence of fractures or cracks in the concrete is prevented, which reduces permeability and allows for reducing the rebar to be contained in the structure, also increasing operational safety. Furthermore, the invention has a system for anchoring the mooring lines to the structure in the form of a truss made of reinforced concrete which evenly distributes mooring stresses, minimizing prestressing in the high area of the platform, and increasing the area for distributing shear forces due to the change in section between the platform and the tower of the wind turbine. The geometric design furthermore confers the versatility of being able to adopt low draft SPAR, semi-submersible, barge, or buoy solutions, with the wind turbine being installed such that it is centered or off-center on the structure, thereby being adapted to different draft requirements or environmental and logistics conditions.
