Definitions

  • the subject invention is directed to hybrid systems and methods for generating energy from wind and wave power, and more particularly, to offshore wind-wave power plant constructions, and still more particularly, to power plant constructions that includes a wind turbine and a wave power generation apparatus associated with the foundation/structure used to support the wind turbine offshore.
  • renewable energy resources such as solar power, wind power and wave power are seen as beneficial in reducing the risks of atmospheric pollution and change to the earth's climate which may arise from the extensive use of fossil fuels, and also in reducing dependence on fuel resources which may become expensive or scarcer in future.
  • the oscillating water column has become a very popular method of converting wave energy into electrical power, whether as a shore-based device, such as that disclosed in U.S. Patent No. 5,191,225 to Wells or a floating device, such as that disclosed in U.S. Patent Application Publication No. 2010/0025996 to Edwards et al.
  • the disclosure contained in each of these patent publications is incorporated herein by reference.
  • the water level oscillates up and down within a water column as the crests and troughs of the waves pass through the water column. If this oscillating water level is made to take place in a structural column opened at both ends, the air column above the water oscillates in a similar manner and, thus, wave energy is thereby converted into low pressure, high volume air flow. Energy is then extracted from the moving air by a self- rectifying Wells turbine, for example, in which rotation is unidirectional regardless in which axial direction air is flowing. In essence, the Wells turbine is essentially operated as a wind or aero turbine. The working interface is therefore between water and air, and air and rotor blades.
  • annular float 10 bobs up and down with the waves around a mostly submerged support structure 20, working an internal plunger 30 that is connected to a hydraulic pump.
  • the joints 25a-c which connect the float 10 to the support structure 20 and plunger 30 are in frequent contact with the seawater and therefore, are susceptible to corrosion and failure.
  • Publication No. 2010/0025996, which is herein incorporated by reference, include a floating platform or support structure which is not capable of surviving large storm waves.
  • the present invention is directed to an offshore hybrid wind-wave power plant, which includes, inter alia, a base substructure that has a tubular support element that defines an internal chamber.

  • a base substructure that has a tubular support element that defines an internal chamber.
  • At least one water inlet is formed in the base substructure and is positioned below mean water level such that a water column level within the internal chamber oscillates with each passing wave.
  • the number of tubular support elements, internal chambers and water inlets can vary without departing from the inventive aspects of the present disclosure. For example, depending on the type of substructure used in the design, the number of internal chambers which contain an oscillating water column used for wave power generation, can be increased or decreased based on for example the number of support legs used in the substructure.
  • the offshore hybrid wind- wave power plant of the present invention also includes a wind turbine for generating wind power.
  • the wind turbine is supported by a tower structure that extends vertically from the base substructure.
  • a generator is operatively associated with the internal chamber defined in the base substructure such that the generator creates power based on the oscillating water column within the base structure.
  • the offshore hybrid wind- wave power plant of the present invention further includes a foundation element for securing the base substructure to sea bottom.
  • the base substructure can be, for example, a monopile structure, a jacket structure, a tripod structure, or a gravity base structure.
  • the oscillating water column compresses and expands air contained within the internal chamber formed in the tubular support element of the base substructure and the compression and expansion of the air is used to move a piston element associated with the generator.
  • the offshore hybrid wind- wave power plant further includes an air duct in communication with the internal chamber defined in the base substructure.
  • the generator includes a piston positioned with the air duct and piston driven gearbox.
  • the generator can include a bi-directional turbine or a pneumatic power generator operatively associated with the internal chamber. It is envisioned that the bi-directional turbine can be a Wells turbine.
  • the preferred embodiments of the present invention are more cost effective than prior art designs/constructions because they leverage the structure and infrastructure of existing offshore wind farms, taking advantage of their foundation structure and electrical grid.

Abstract

L'invention porte sur une centrale électrique hybride en mer houlomotrice et éolienne qui comprend, entre autres choses, une sous-structure de base qui comprend un élément support tubulaire qui définit une chambre interne. Au moins une entrée d'eau est formée dans la structure de base et est positionnée au-dessous du niveau moyen de l'eau, de telle sorte qu'un niveau de colonne d'eau dans la chambre interne oscille à chaque vague qui passe. La centrale électrique hybride en mer houlomotrice et éolienne de la présente invention comprend en outre une turbine éolienne servant à générer une énergie éolienne. La turbine éolienne est supportée par une structure de tour qui s'étend verticalement à partir de la sous-structure de base. En outre, un générateur est associé fonctionnellement à la chambre interne définie dans la sous-structure de base, de telle sorte que le générateur crée de l'énergie basée sur la colonne d'eau oscillante dans la structure de base.
