【Abstract】 To solve the problem that most ocean data buoys are powered by solar cells and storage batteries,a power supply device based on wind energy,solar energy and current energy is proposed. The device uses double-rotor generator as co-carrier of wind energy and power flow energy,and has superior performance of high generation efficiency and small volume and light weight. Magnetic levitation bearing is used to reduce mechanical friction power consumption of double-rotor generator. The dual-rotor generator is used as the carrier of wind energy and power flow energy co-generation. It has the advantages of high power generation efficiency and small volume and light weight. The magnetic bearing used in the device reduces the mechanical friction power consumption of the dual-rotor generator.Based on the analysis of the operation principle of photovoltaic power generation and wind-current power generation,and combined with the power demand of buoys,the model establishment and parameter design of each power generation module are carried out. The research shows that the power supply device can make full use of the time and space complementarity of various energy sources,meet the power demand of each equipment of the buoy stably,and ensure its long-term and efficient operation.更多还原
