Description

Technical field: [0001] The invention relates to a control system of a land simulation experiment platform for high-power ocean temperature difference power generation. Background technique: [0002] Ocean thermal power generation is a thermoelectric conversion technology that uses the thermal gradient between the surface temperature seawater and the deep cold seawater to generate electricity. It is the most stable renewable energy in marine renewable energy, and it has huge reserves. Energy resources are very rich, with a theoretical installed capacity of 3.67×10 8 kW, calculated according to the utilization rate of 2%, the annual power generation capacity can reach 57 billion degrees. In addition, the ocean temperature difference can generate a large amount of high-quality deep cold seawater, which is rich in minerals, making the added value of this technology higher. . [0003] Since most of the ocean thermal energy resources are located in the deep sea, the high invest...

Problems solved by technology

[0004] At present, the power of the existing simulation experiment test platform in China is small, and the cold and heat sources mostly adopt heat storage and cold storage. This type of experimental platform has many disadvantages, the biggest disadvantage of which is that it limits the testable ocean temperature difference energy thermoelectric conversion system. With the increase of power generation, the power of the testable ocean thermoelectric power generation system is small and the test time is limited. The cold and heat source simulation system based on the heat pump is the development of the cold and heat source simulation method for the land experimental test platform of ocean thermoelectric power generation in my country. trend, not only can increase the power generation of the testable ocean thermal energy generation system, but also the experiment time can be unlimited
