WIND POWER GENERATION TOWER PROVIDED WITH GYROMILL TYPE WIND TURBINE (VERSIONS) Russian patent published in 2018 - IPC F03D3/00 F03D3/04 F03D3/06 

FIELD: power engineering.

SUBSTANCE: invention relates to a wind power generation tower (versions). Wind power generation tower comprises a wind collection section including wind inlets, into which wind enters, the inlets being formed in a plurality of tiers, and each tier being configured to change a strength and direction of the wind; and an energy conversion section configured to convert energy of the wind while the wind passes therethrough, wherein the wind collection section includes a plurality of wind guide walls disposed radially around the centre of the wind power generation tower so that the wind flowing in through the wind inlets can flow in a radial direction of the energy conversion section; the energy conversion section includes therein a Gyromill-type wind turbine installed at the centre of each tier of the wind power generation tower, the Gyromill-type wind turbine including Gyromill-type wind blades having a tip-speed ratio (TSR) in the range of 1.1 to 2.4, a solidity of 0.2 or more, and RPM of 240 or less; and the energy conversion section includes wind flow paths formed in the space between the wind guide walls and the wind blades, and inner flow paths formed in the space between the wind blades at the centre of the wind power generation tower and is divided into four equal parts with reference to a direction perpendicular to a wind blowing-in direction of the wind power generation tower to define the parts as first to fourth regions. Plurality of wind guide walls are formed to have an inclined angle that causes the winds passing through the wind collection section to flow to the outside through the first and fourth regions of the energy conversion section. When the wind blades rotate counterclockwise, the length of the wind flow paths is set such that the wind speed flowing through the wind flow paths of the first and fourth regions of the energy conversion section, is not lower than the wind speed flowing through the inner flow paths of the first and fourth flow regions. When the wind blades rotate clockwise, the length of the wind flow paths is set such that, the wind speed flowing through the wind paths of the second and third regions of the energy conversion section is not lower than the wind speed flowing through the inner flow paths of the second and third flow regions. When the wind blades rotate counter-clockwise, the minimum length of the wind flow paths of the energy conversion section extends to a position, at which positive torque is initially created in the fourth region, and the maximum length of the wind flow paths is equal to the radius of the wind turbines. When the wind blades rotate clockwise, the minimum lengths of the wind flow paths of the energy conversion section extends to a position at which a positive torque is initially created in the third region, and the maximum length of the wind flow paths is equal to the radius of the wind turbines. When the wind blades rotate counterclockwise, the angle of attack of the wind blades is set so that a positive torque is created in the first and fourth regions. When the wind blades rotate clockwise, the angle of attack of the wind blades is set so that a positive torque is created in the second and third regions.

EFFECT: wind power generation tower is proposed.
