Title:
WIND TURBINE FOR LOW WIND SPEED, AND WIND TURBINE SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/065927
Kind Code:
A1
Abstract:
According to the present invention, a block multistage structure is configured in an overall upright or twisted structure, and a drag-type blade forming an inner overlapping region is adopted, such that the amount of starting torque for rotating the blades of a wind turbine from a standstill is large in order to achieve aerodynamic properties in which a moment of rotation becomes greater. Airfoil-type blades are adopted on the outside in order to obtain a rotation acceleration having a velocity ratio of 1.0 or greater, wherein wind power generation can be performed under low wind conditions regardless of wind direction, and wind power generation that is economical, environmentally friendly, and has very high efficiency can be performed regardless of location or position and with low installation costs.
