Wind energy-wave energy integration power generation structure based on floating type tension leg platform

Abstract

A wind energy-wave energy integration power generation structure based on a floating type tension leg platform comprises a floating type tension leg wind power generation structure and a wave power generation device. The floating type tension leg wind power generation structure comprises a wind turbine, a tower structure, a tension leg type supporting platform structure and a matching power transmission system. The wave power generation device is arranged on the water surface of the tower structure, and the wave power generation device is in coupling connection with the outer side face of the tower structure through a slide way type contact device. The wind energy-wave energy integration power generation structure has the advantages that the structure is reasonable and stable in structural design, the technology is mature in the construction scheme, the supporting platform structure and the power transmission system are shared, construction cost of independently using the wind turbine and the wave power generation device is reduced, the tension leg structure is favorable for optimal control of movement and improvement of utilization efficiency of wave energy. A system of the wind energy-wave energy integration power generation structure can be widely applied to development of deep water wind energy-wave energy resources.

Description

technical field [0001] The invention belongs to the field of ocean energy utilization, in particular to a comprehensive utilization device for wind energy and wave energy. Background technique [0002] Offshore wind energy and wave energy are both clean and renewable ocean energy. Wind power can be used to convert wind energy into electrical energy, and wave power can be used to convert wave energy into 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 stable wind power, larger wind turbine unit capacity, higher annual effective utilization hours, less restricted by noise standards, and more convenient transportation conditions. Wave energy resource...

AI Technical Summary

Problems solved by technology

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

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 comprehensive development of marine energy that integrates wind power generation and wave power generation. structural system
