Embodiment Construction

[0027] Referring to the drawings, wherein like reference numerals refer to like or similar elements, a suspended wind turbine system according to a first embodiment of the present invention is generally designated 10 and comprises: a central shaft 12; a turbine section 14, the turbine Section 14 includes front wind turbine 16 and rear wind turbine 18 rotatably mounted to shaft 12; generator 20, which converts rotation of turbines 16, 18 into electricity; and lifting structure 22, which A lift structure 22 is coupled to the turbine section 14 for generating a lift force to enable the turbine section 14 to be lifted into the atmosphere. Although referred to as a central axis because the shaft 12 is preferably located in the axial center of the system 12, it is conceivable that the shaft 12 could be positioned eccentrically, and thus the central nature of the shaft 12 should not be viewed as a limiting feature, but rather is a preferred feature only.

Abstract

An airborne system (10) for producing electricity from wind energy includes a shaft (12), at least two turbines (16, 18) rotatably mounted to the shaft (12) and arranged to rotate independent of one another and in opposite directions when subjected to the same wind, and generators (20) which convert rotation of the turbines (16, 18) into electricity. The magnitude of electricity generation by the generators (20) is related to the magnitude of torque induced by the generators (20) on the shaft (12), and the electricity generation by the generators (20) may be controlled such that torques induced on the shaft (12) by the generators (20) is controlled such that a sum of torques induced on the shaft (12) is substantially zero. A lifting structure (22) generates a lifting force to lift the turbines (16, 18) to a desired altitude, and an anchoring system (56) anchors the turbines (16, 18) relative to the ground. Generated electricity is conducted to users, to electricity storage, or to processing components.

Description

technical field [0001] The present invention relates generally to a wind turbine system for generating electrical power, and more particularly to such a wind turbine system for generating electrical power that is airborne and in a public The suspension structure includes both the turbine and the generator. Background technique [0002] Wind energy is one of the most readily available forms of natural energy (including solar, hydro, geothermal) and is therefore often used to generate electricity. In terms of watts per square meter, wind energy has one of the highest densities of any other form of natural energy. [0003] Existing systems for generating electricity from wind energy have certain disadvantages. For example, because wind speed generally increases with height, and high wind speeds are critical to optimizing wind-based power generation, tall towers should be constructed to elevate wind turbines to high operating heights in order to enable the generation of electr...
