PLANT FOR ELECTRIC POWER GENERATION FROM WIND ENERGY Russian patent published in 2016 - IPC F03D1/04 F03D7/00 F03D9/00 

FIELD: power industry.

SUBSTANCE: invention relates to devices for power generation from wind energy. The wind-driven power generation plant comprises the casings, each of which has a mouth; wind turbines, each of which is located in the mouth of one of casings; the power supply system for conversion of mechanical energy taken from wind turbines into electric energy; blocks, each of which contains at least two casings and related wind turbines, and the power supply system; the rotary assembly system for rotary support of each of blocks; the supporting framework supporting blocks above the surface. Each of casings in addition contains internal surface and external surface which converge in the circular front edge and the circular back edge, and the circular front edge has the edge diameter, the half of radial cross section of internal and external surfaces form a pattern the rotation of which around the horizontal axis of the casing defines internal and external surfaces; the internal front curve of internal surface with the shape which maximizes the weight and speed of the wind passing through the mouth with the diameter D and minimizes the wind swirling and resistance along internal surface of the casing, while the internal front curve begins in the point at the circular front edge the distance from which to the casing axis is within 0.55D-0.95D, passes to the named axis in the direction within the angle 15° with reference to the plane, perpendicular to the axis, and ends in the mouth in the direction within the angle 15° with reference to the line parallel to the named axis; the external front curve of external surface with the shape which maximizes the mass of the wind passing through the mouth in combination with the shape of the internal front curve and minimizes the wind swirling and resistance along external surface of the casing, and the named external front curve begins at the circular front edge, passes in the direction from the axis within the angle 15° with reference to the plane, perpendicular to the axis, and ends in the direction within the angle 10° with reference to the line parallel to the axis, at the distance within 0.6D-2.0D from this axis.

EFFECT: invention is aimed at increase of power generation capacity.
