Description

technical field [0001] The invention relates to the technical field of offshore wind turbine foundations, in particular to a wind energy and wave energy combined power generation device based on a jacket foundation. Background technique [0002] With the continuation of the world's energy crisis and the destruction of the environment by fossil energy consumption, human demand for renewable clean energy is increasing. The exploration and research of renewable clean energy has gradually extended from land to the vast ocean. Offshore wind energy is currently the most It is one of the clean energy with commercial development value and the most mature technology. It has the characteristics of abundant reserves, stable and continuous power generation, and high hours of power generation. It is suitable for large-scale development. According to incomplete statistics, my country's offshore wind energy reserves exceed 700 million kilowatts. Estimated development value. Offshore wind po...

AI Technical Summary

Problems solved by technology

[0003] Wave energy and offshore wind energy are also renewable clean energy with huge reserves. The difference between them and offshore wind energy is that the existing wave energy power generation devices have the defects of less energy absorption, low conversion rate, high cost and high damage rate. The bottleneck of wave energy has led to the fact that wave energy does not yet have the value of large-scale development. Most of the wave energy power generation devices launched by scientific research institutes and enterprises on the sea are single-point launch, which are only used for scientific research and teaching, and do not have the conditions for grid-connected power generation.

[0004] Aiming at the defects of low conversion rate of wave energy generation device, high cost of support structure, and easy to be corroded by seawater, with the help of the stable support structure of offshore wind power and the coexistence of offshore wind power and wave energy, a joint offshore wind energy and wave energy based on support structure is studied. The power generation device is of positive significance to reduce the cost, improve the power generation efficiency, and realize the commercialization of wave energy development
