Abstract

The invention discloses a wind energy / wave energy integrated power generation device and a power generation method thereof. The wind energy / wave energy integrated power generation device comprises a hollow pile; the bottom of the hollow pile is inserted into the bottom of the sea, and the top of the hollow pile extends out of the surface of the sea; wind driven generator blades are installed on the top of a tower; electricity generated by a wind driven generator is transmitted to a controller in the tower; the controller supplies power to various components in the wind driven generator; the controller is also electrically connected with an external grid through a cable; the hollow pile is sleeved with a water storage pool; the top of the water storage pool is located above the surface of the sea; a rising slope is arranged between the surface of the sea and the top of the water storage pool; the bottom of the water storage pool is below the surface of the sea; a descending slope is arranged between the surface of the sea and the bottom of the water storage pool; the rising slope and the descending slope are in butt joint with each other so as to form an ice-resisting cone; the upper part of the water storage pool is open; two or more water-discharging holes are formed in the bottom of the water storage pool; and water turbines are installed in the water-discharging holes respectively. According to the power generation device of the invention, a relatively mature offshore wind power technology and a wave energy power generation technology with a great development potential are combined together so as to form a complementary power generation system, and therefore, grid-connected power generation can be realized with high possibility; offshore wind energy foundation pilesare effectively utilized; and a wave energy generation device and a wind energy power generation device share one set of power transmission system, and therefore, the power generation cost of the waveenergy power generation device can be decreased.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of wind energy and wave energy at sea, and in particular relates to a wind energy wave energy comprehensive power generation device and a power generation method in the field. Background technique [0002] The 21st century is called the century of the ocean. In the face of the rapid expansion of the world population, the depletion of land resources, and the deteriorating environmental conditions, it has gradually become a consensus to obtain clean and renewable energy from the ocean. Ocean energy is a renewable energy stored in seawater. In a broad sense, ocean energy includes offshore wind energy, offshore solar energy, wave energy, tidal energy, ocean current energy, temperature difference energy, and salinity difference energy. Its reserves are huge and widely distributed. At present, offshore wind power technology is relatively mature. Compared with onshore wind energy, offshore wind e...
