System and methods for controlling the oscillation of floating ground stations in aerial wind turbine systems are disclosed. Thrusters on the ground station or on one or more aerial vehicles associated with the ground station apply a compensatory force to the oscillating ground station to reduce and/or substantially eliminate wave-induced oscillations. Submerged thrusters may also rotate the ground station to a preferred alignment direction with the waves. Additionally, control systems use environmental and/or positional sensor data to develop a predictive force profile that maps desired compensatory force magnitude versus time. The control systems use that predictive force profile to direct the thrusters to apply a varying compensatory force over time.

A self-aligning to the incoming wind floating platform supporting multiple wind turbines(17, 18) forms a wind power generation unit. Under horizontal wind, the wind load resultant passes the center of geometry of the wind load receiving areas (hereafter C.Geo) of the floating platform, but not the turning axis (15), resulting a yaw moment about the turning axis (15) to turn the floating platform until the wind load resultant passes through the C.Geo and the turning axis (15) simultaneously.

A lift-driven wind turbine has a turbine rotor with blades mounted to the turbine shaft by two struts hinged to the shaft and each blade to form a four-bar linkage. The blades' airfoil cross section generates lift that rotates the blades around the axis in the presence of a prevailing wind. The airfoil chord forms a geometric angle of attack αG relative to the tangent of the blade path and the struts orient the blades with an outward tilt angle γ. The turbine is designed with values of αG and γ that cause the lift generated by each blade to have an upward component that supports the blade against the force of gravity and a mean radially inward component that substantially balances centrifugal forces on the blade. Wind turbines designed according to the principles disclosed herein facilitate the construction of free-floating utility scale wind turbines for deep water installations.
