ORTHOGONAL TYPE WIND POWER PLANT Russian patent published in 2022 - IPC F03D3/06 F03D7/06 F03D3/02 

FIELD: power engineering.

SUBSTANCE: scope of use: in the design of wind power plants with a vertical axis of rotation, designed to provide electricity to household and industrial power grids that consume low and medium power. An orthogonal wind power plant includes a mast with an electric generator and a wind wheel in the form of traverses radially extending from the mast at the junction of the generator shaft with vertical blades of an aerodynamic profile facing the bulge to the axis of rotation of the wind wheel. Each blade of the wind wheel is equipped with an additional blade with the same aerodynamic profile and chord size, while the additional blade has a typical slat for subsonic speeds and is mounted relative to the blade with a bulge to the axis of rotation with an offset to the axis of rotation by 1/3 of the chord and 2/3 of the chord in the direction of rotation of the wind wheel. The wind wheel is divided into three parts, the extreme ones rotate in the opposite direction relative to the central part, the height of the blades of which is twice the height of the blades of the extreme sections. The ends of the blades on all three sections of the wind wheel are equipped with barriers that prevent disruption of the air flow, made in the form of rings. The rotor of the electric generator is mechanically connected to the extreme sections of the wind wheel, and the stator is connected to the central section of the wind wheel to ensure rotation of the rotor and the stator of the electric generator in opposite directions. The electric generator is located in the central part of the wind wheel. In the rotor of an electric generator made in the form of flat parallel disks with annular rows of permanent magnets, the polarity of which alternates in a row, an even number of permanent magnets are located on one disk, and on the second disk an even number, increased by a pair or a multiple of a pair of permanent magnets, and the winding of the windings on the stator is made obliquely, in accordance with the displacement the magnetic field caused by the displacement of the permanent magnets in the upper row relative to the permanent magnets of the lower row.

EFFECT: increase in the relative speed of the sections of the divided wind wheel; an increase in the useful area of the blades of the wind wheel; an increase in the power of the wind power plant; elimination of the effect of “sticking” of permanent magnets due to the inclination of the magnetic field.
