Description

Technical Field

[0001] The present invention relates to the technical field of wave power generation platforms, and in particular to an ocean floating platform wave energy power generation system and a working method thereof. Background Art

[0002] With the development of the global economy, the demand for energy is increasing. Traditional fossil energy faces problems such as limited reserves, environmental pollution and climate change. Therefore, the development and utilization of renewable energy has become an important direction for global energy development.

[0003] The ocean covers about 70% of the earth's surface. Wave energy is a widely available renewable energy source with a relatively high energy density. The theoretical reserves of global wave energy are huge. It is estimated that the exploitable potential of wave energy far exceeds the current human demand for energy. The use of wave energy does not produce greenhouse gas emissions and has minimal pollution to the environment. Compared with fossil energy, wave energy is a clean energy source that helps alleviate global climate change. The movement of waves has a certain regularity and predictability. Through meteorological and oceanographic data, the generation of wave energy can be predicted to a certain extent, which is convenient for the effective use of energy and the stable access to the power grid.

[0004] Most of the early wave power generation devices were based on simple mechanical principles, such as pendulum type, oscillating water column type, etc. These devices have large energy losses during the energy conversion process, resulting in low overall power generation efficiency. Due to the harsh marine environment, wave power generation devices need to withstand a variety of adverse factors such as strong winds, large waves, corrosion and biological adhesion. Many early wave power generation devices are prone to equipment failures and poor reliability during long-term operation. The research and development, manufacturing, installation and maintenance costs of wave power generation devices are high. The complex marine environment requires the equipment to have high strength and corrosion resistance, which increases the manufacturing cost of the equipment.

[0005] At the same time, due to frequent equipment failures and high maintenance costs, the large-scale application of wave energy generation technology is limited. This technology has good adaptability and flexibility, and can be designed and adjusted according to different sea conditions and wave conditions. At the same time, the floating platform structure facilitates modular design and mass production, which helps to reduce costs.

[0006] In summary, the emergence of wave energy power generation floating platform technology is to overcome the limitations of existing wave energy power generation technology, utilize wave energy resources more efficiently, reliably and economically, and meet the growing energy demand and environmental protection requirements.
