【Abstract】 Research on high-efficiency wave energy generation system can solve the problem of energy shortage in China’s islands. According to the characteristics that the frequency of the main band of wave power spectrum is higher in China and the energy is significantly concentrated in a certain frequency band, the wave power generation system based on cross-flow rotor is studied combining with inner flow channel design. The natural frequency of water body changes with the change in incident wave frequency, so the system can absorb the wave energy within the main frequency band of wave power spectrum. Using seawater as the working medium, the system is featured by direct drive rotary generators and floating installation. The main contents of the study are to determine the shape of the inner flow channel based on the wideband design theory of wave energy generation,which can guarantee that the incident wave excitation fully converts into water body oscillation in the flow path.The wave energy generation system studied in this paper has a wide working bandwidth, and is suited to China ’s coastal wave energy conditions. The findings can be used to improve the efficiency of system operation, establishing a solid foundation for the theoretical research and practical applications in the field of wave energy generation.The wave energy generation device has undergone real-sea state testing.更多还原
