Abstract

A wind energy-wave energy-tidal current energy integrated power generation structure based on a single pile platform comprises a single pile platform wind power generation structure, a wave energy power generation device and a tidal current energy power generation device, the single pile platform wind power generation structure comprises a wind machine, a tower frame structure, a single pile supporting structure and a matched power transmission system, the wave energy power generation device is arranged on the water surface of the tower frame structure, and the tidal current energy power generation device is arranged on an underwater single pile supporting structure. The wind energy-wave energy-tidal current energy integrated power generation structure has the advantages that the single pile platform structure is convenient to construct, low in construction cost and wide in application range, the wind power generation structure, the wave energy power generation device and the tidal current energy power generation device share the single pile supporting structure and the power transmission system, the unit power generation cost can be effectively reduced, the structural design is reasonable and stable, the construction scheme is mature in technology, existing commercial products can be selected by a wind power generator and a tidal current power generator, modeling is simple and convenient to achieve, and performance optimizing design can be performed on a wave energy power generator by combining wave statistical features of a site selecting place.

Description

technical field [0001] The invention belongs to the field of ocean energy utilization, in particular to a wind energy-wave energy-tidal current energy comprehensive utilization device. Background technique [0002] Offshore wind energy, wave energy and tidal current energy are all clean and renewable marine energy sources. Wind energy can be converted into electrical energy by wind power generation devices, wave energy can be converted into electrical energy by wave power generation devices, and tidal current energy can be converted into electrical energy by tidal current power generation devices. electrical energy. The exploitable offshore wind energy resources in the eastern coast of my country are about 750 million kilowatts, which not only has huge resource potential, but also has good market conditions for development and utilization, and is closer to China's economic center. Offshore wind energy development has the advantages of saving precious land resources, more st...

Problems solved by technology

[0004] The disadvantages of the existing technology are: the energy conversion rate of the wave power generation device and the tidal current power generation device is low, and the unit power generation cost is high, which limits the commercial application of the two

Although offshore wind power generation has the advantages of saving land resources, large single-unit capacity, high annual effective utilization hours, small noise standard restrictions, and convenient transportation conditions, there is still a lack of integration of wind power generation, wave power generation and tidal current power generation.
