Vertical axis wind turbine system for power generation

Abstract

A vertical axis wind turbine system for power generation which has at least one wind rotor which has at least three blades spaced apart from each other in a uniform angle pitch, the blades have a concave and an opposite convex surface, and in at least one wind rotor the blades are arranged in a plane perpendicular to the axis (13), and the at least one wind rotor is supported by bearings for rotation about the vertical axis (13) and located on the top of a column (10) and / or support rod (52), and the system includes a device for converting the rotational energy of the rotated axis (13) into another type of energy, wherein the blades (15, 16, 17; 59, 60, 61, 62) are arranged along the sides of a regular polygon (21) surrounding the axis (13) as the center and in the plane, and their extensions where each side has a side length M, and the convex side of the blades faces the inside of the polygon, the inner end of each blade (15, 16, 17; 59, 60, 61, 62) extends at least to the midpoint of the side to which it belongs, and the total length (L) of blades (15, 16, 17; 59, 60, 61, 62) shall be at least 2.5 times the mentioned length of the side (M) that is L > 2.5 M, and the number of the sides of the polygon being not less than 3 and not more than 6.
