Description
Technical Field
The invention belongs to the technical field of ocean renewable energy development and utilization, and particularly relates to a semi-closed wave energy recovery and energy storage system.
Background
Energy problems in the world today have become a core interest issue of concern in all countries. Under the large background that fossil fuel energy is increasingly deficient, how to develop renewable energy has important significance for the development of energy strategy in China. A large amount of renewable energy sources in the ocean can be utilized, such as wind energy, tidal energy, wave energy, salinity gradient energy and the like, but most of the renewable energy sources are not exploited and utilized due to the great difficulty in conversion and storage.
Under the background, the research on the development mode of the ocean renewable energy can improve the competitiveness of energy development in China and the speaking right of China in the world energy field on the one hand; on the other hand, the method can practically solve the problem of energy shortage in coastal areas around China, and has great strategic significance for optimizing energy structures in China, improving energy safety of China and developing low-carbon economy.
The wave energy power generation is a power generation technology which utilizes the motion of waves to drive a power generation mechanism to generate power and converts potential energy and kinetic energy existing in the waves into electric energy. Wave energy reserves are abundant in offshore sea areas in China, but large-scale development is difficult due to the fact that the wave energy reserves are low in grade and high in development difficulty, and the wave energy reserves are not stable in power and are not easy to store and transport. Wave energy development has been studied earlier in the world, and has had some commercial effect in france, norway, uk, japan, etc. However, the wave energy in China starts to be researched later, but through decades of researches, great progress is made. In the future, wave energy is used for a sea mountain drilling platform, an offshore lighthouse and an ocean fishing boat, a wave energy generating set can be built in an offshore sea area rich in wave energy to supply power to a power grid, and power generation can be used for sea water desalination, electrolytic hydrogen production, offshore operation and the like in the offshore area.
The super capacitor (EDLC) is a novel energy storage device, can adapt to charging and discharging of non-constant power (as long as the rated voltage of the super capacitor is not exceeded) due to the unique charging and discharging principle (physical charging and discharging), and is very suitable for storing and converting the energy of the non-constant power. Wave energy is not constant in generated power due to its instability, and thus its storage and conversion of energy has also been a big problem. The super capacitor is used for storing and converting wave energy, and the problem that the generated power is unstable can be well solved. The super capacitor can temporarily store electric energy, and can also discharge the energy at constant power after charging to a certain capacity to supply the energy to a carrying platform.
