Abstract:In recent years,many large ocean buoys have been put into use, and the types and quantities of observation equipment and intelligent sensors equipped with them have become more diversified,and the increase in load has put forward higher requirements for the power generation and operation stability of the buoy power supply system.Aiming at the characteristics of high energy consumption of large marine buoys,a set of integrated power supply system model of wind-solar diesel storage is built in the MATLAB/Simulink platform,combined with the oscillation of buoys in the marine environment and the high temperature phenomenon in the cabin,an energy coordination control strategy of the power supply system is designed,and the simulation experiment of the operating state of the system under complex working conditions is carried out.The correctness of the model and the feasibility of the control strategy are verified by the experiment.
