Filed:

Sep 15, 2015

Appl. No.:

14/855134

Inventors:

- Seattle WA, US
Zachary Murphree - Dallas TX, US
Antoine Peiffer - Oakland CA, US

Assignee:

OSCILLA POWER, INC. - Seattle WA

International Classification:

F03B 13/22
E02B 9/08

Abstract:

A device for converting wave energy includes a surface float, a heave plate, at least one load carrying structure that is mechanically coupled to at least one component of at least one generator on the surface float and the heave plate. The heave plate has an asymmetric geometry to facilitate a first level of resistance to movement in an upward direction and a second level of resistance in a downward direction. The first level of resistance is higher than the second level of resistance. The at least one load carrying structure includes a flexible tether. The at least one component is configured to experience force changes caused by hydrodynamic forces acting on the surface float and heave plate.

Abstract:

A method for controlling an inclination of a floating wind turbine platform comprising a generator, a set of turbine blades connected to a shaft inside a turbine nacelle, the turbine nacelle being mounted onto a tower, and at least three stabilizing columns is presented. Each of the at least three stabilizing columns have an internal volume for containing ballast. Position data associated with an orientation of the floating wind turbine is received. A heel angle in reference to the floating wind turbine platform is determined based on the position data. A first signal for adjusting at least one of a blade pitch of the set of turbine blades, and a torque of the generator is sent based on the determined heel angle. A second signal for distributing the ballast among the at least three stabilizing columns is also sent. The second signal for distributing the ballast is based on the determined heel angle and the first signal.
