4. WOWO/2015/009175 - PSP WIND-POWERED GENERATOR COMPRISING BLADES AT DIHEDRAL ANGLES22.01.2015
F03D 1/06
PCT/PE2014/000010SAAVEDRA PACHECO, PedroSAAVEDRA PACHECO, Pedro
The invention relates to a wind-powered generator comprising blades at dihedral angles (PSP), characterised by an aerodynamic, semi-flat blade having, on one if its sides, a bent section measuring approximately a quarter of the total width of the blade and forming a dihedral angle of less than 30°, the interior space of which captures the kinetic power of the wind impacting on the blade, thereby generating a powerful rotary movement in that direction. The blades form a diametrical set of two blades generating a strong and effective rotary movement at a 90° angle to the linear movement of the wind. The invention can be used to create: a generator comprising one single set of two blades; a generator comprising two sets of blades moving in one direction and generating an aggregate output; and/or a generator comprising two sets of blades rotating in opposite directions that generate twice the output of a set of blades rotating in one direction, with one single fixed and mobile structure, one single generator and one single wind mass.

5. WOWO/2015/004737 - FLOATING OFFSHORE WIND POWER GENERATING DEVICE AND TRANSFORMER USED IN SAME15.01.2015
F03D 11/00
PCT/JP2013/068793HITACHI INDUSTRIAL EQUIPMENT SYSTEMS CO., LTD.MASHIMA Yasushi
In floating offshore wind power generating devices, with the objectives of safety and of suppressing loss during power transmission, there have been requests for installing a transformer in floating offshore wind power generating devices. At such a time, the transformers installed in floating offshore wind power generating devices are agitated by wind and waves, and so there has been the possibility of incurring transformer damage. As a result, in the present invention, the transformer is disposed at the vicinity of the metacenter, which is the center of the tilting of the floating offshore wind power generating device. As a result, it is possible to suppress agitation of the transformer due to wind and waves, optimize transformer anti-agitation measures, and to reduce costs.
