Research on the Distribution Characteristics of Temperature Difference Energy and Site Selection in the South China Sea
In order to quantitatively evaluate the power generation capacity of island based temperature difference generation platforms in the South China Sea region,and provide reliable theoretical basis for optimizing the site selection of temperature difference energy generation platform,this paper is based on a global water temperature distribution dataset and uses data reanalysis methods to establish a three-dimensional mathematical model for the distribution of thermoelectric energy in the South China Sea.A quantitative evaluation of the spatiotemporal distribution characteristics of thermoelectric energy in the South China Sea is carried out,and explored the impact of different site locations on the efficiency of temperature difference energy utilization.The research results indicate that the annual average temperature difference between the 800 m depth and surface water temperature in the South China Sea is around 23 ℃,and the annual temperature difference variation amplitude is within 3 ℃.The temperature difference energy resources in the South China Sea reached their peak within the year in summer,and the net power of temperature difference energy in the Sansha Sea area was above 19 MW;Winter is the lowest period of thermal energy level in the South China Sea.The thermal energy of the Xisha Islands is only about 12 MW,and that of the Zhongsha Islands is about 15 MW.The temperature difference energy increases significantly with the increase of water depth.The net power difference of temperature difference energy under the same water depth condition is very small,but the offshore distance difference corresponding to different site selection schemes is more significant.
