Description

technical field [0001] The invention relates to a novel offshore power station, in particular to an offshore floating wind-force ocean current and wave power station. Background technique [0002] The ocean is a treasure land of energy storage on the earth, containing abundant wind energy, wave energy and ocean current energy resources. Offshore wind energy resources, as a clean and renewable energy source, have huge reserves. The exploitable offshore wind energy resources in the east coast of China amount to about 750 million kilowatts; According to ocean observation data, the total amount of wave energy resources is about 500 million kilowatts, and about 100 million kilowatts can be developed and utilized; China is also rich in ocean current energy, and the theoretical average power along ocean currents is 140 million kilowatts. [0003] The use of ocean energy is the direction of energy research in the world today, especially in the situation where energy is related to n...
