||PCT/PE2014/000010||SAAVEDRA PACHECO, Pedro||SAAVEDRA 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

||PCT/JP2013/068793||HITACHI 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.
