Problems solved by technology

[0004] However, they all generate power from a single ocean temperature difference, and their energy utilization is single, and their thermal cycle efficiency is low, less than 4%.
[0012] 1) The form of energy utilization is single, only ocean temperature difference energy is used, and clean energy such as wind energy and solar energy are not utilized
[0013] 2) The thermal cycle efficiency of the ocean temperature difference power generation system is low, generally less than 4%
[0014] 3) The development of this traditional technology is slow: the expansion of power amplification is slow
[0015] 4) The experimental results of ocean temperature difference power generation in China show that the conversion rate is low, less than 4% in the world, and typically only 1-3%;
[0016] 5) At present, commercialization has not been realized in China, and the technology is constantly improving, so the corresponding electric energy storage technology and electric storage devices are cutting-edge innovations;
[0017] 6) The power generation power of the previous experimental project of ocean temperature difference power generation was relatively small, and there are still areas of continuous improvement in various technologies;

Description

technical field [0001] The invention relates to the technical field of electric energy, in particular to a multi-energy complementary offshore energy integrated power generation system. Background technique [0002] Ocean energy is a green and renewable energy with huge energy. Countries with ocean resources in the world are working hard to develop ocean energy resources and promote the development of new energy technologies related to ocean energy. Among them, ocean temperature difference power generation is one of the new energy technologies for the development and utilization of ocean energy. [0003] At present, the ocean temperature difference energy generation system (OTEC) includes open circulation system, closed circulation system and hybrid circulation system. The open cycle system is composed of a flash evaporator, a steam turbine, a condenser, and a seawater pump. The first working process is to pump warm seawater into the flash evaporator to evaporate part of it...
