Definitions

  • FIG. 1 A first figure.
  • the front surface 23 of the rotatable aft float 20 faces toward the oncoming wave and is optimized in both radius and slope in order to maximize energy capture from the incident wave climate. Hydrodynamic numerical analysis and optimization techniques were employed to design the rotatable aft float 20 to maximize power delivered from the rotatable aft float 20 while minimizing the material utilized. Thus this shape (slope and radius) is the result of an optimized power to cost ratio.
  • the front surface 23 of the rotatable aft float 20 is rectangularly shaped to maximize exposed surface area in order to increase energy capture.
  • the damper 35 is mounted to the bottom end region 32 of the spar at point higher than the terminal end 33 of the bottom end region 32 such that the terminal end 33 extends beyond an underside of the damper 35 and the center of gravity and center of buoyancy of the wave energy converter are between the terminal end of the spar 30 and the water surface.
  • the geometry of components of the WEC 10 can be optimized for use on different bodies of water during different seasons based on many factors.
  • the fore float 15 and aft float 20 may be constructed with a narrow width to length ratio, or with a wide aspect ratio.
  • Fore float 15 and aft float 20 geometry is optimized for wave height, wave period, seasonal wave spectral density, power capture, and directionality considerations.
  • the shape of the rotatable fore float 15 and rotatable aft float 20 is not limited by the geometry heretofore described.
  • the WEC 10 body design optimization includes a cost function for materials and manufacturing.
  • the WEC 10 design optimization includes generator torque-speed performance feedback and the costs associated with the generator materials and manufacturing costs.
  • the integration of hydrodynamic optimization, torque-speed optimization and cost reduction define the complete system shapes, centers of gravity and inertias.

Abstract

L'invention concerne un appareil et un procédé de conversion de l'énergie des vagues à l'aide du mouvement de rotation relatif entre deux ensembles flottants reliés l'un à l'autre et le mouvement de rotation relatif entre chacun des ensembles flottants et un espar qui s'étend dans l'eau à partir d'un point de liaison avec les ensembles flottants à la surface de l'eau.
