Abstract
Marine resources exploration and development can’t be separated from the underwater exploration buoy, battery capacity limits the working time and range of the buoy, the use of ocean thermal energy for underwater exploration buoy energy supply can effectively solve the problem of energy supply. The solid-liquid phase change energy storage technology was used to capture ocean thermal energy, and the electro-mechanical system was used to convert ocean thermal energy into electrical energy to realize the self-supply of buoy energy. In this paper, we studied the influence of the system parameters on the system performance by analyzing the working process of the buoy electromechanical system, establishing the mathematical model of the whole system, and combining AMESim/Simulink simulation technology to reveal the law of ocean thermal energy generation. The results show that increasing the volume of the accumulator and reducing the displacement of the hydraulic motor can help to increase the power generation of the generator and choosing a suitable load can help to increase the power generation.
