Simulation And Optimization Design Of An Array Of Cantilever Oscillating Float Wave Energy Conversion Device

Marine renewable energy is a renewable energy vigorously promoted by the Chinese government,which plays an important role in supporting the national industrial restructuring,cultivating emerging industries and exploring energy structure reform.In the past few decades,the Chinese government has implemented specific plans and strategies for marine renewable energy,and given state funding support,and research,development and deployment related to marine renewable energy are also rapidly unfolding.Wave energy is one of the most promising marine renewable energy sources.As a wave energy conversion device for extracting wave energy,it has also been developed rapidly.The point absorption wave energy conversion device,which is more suitable for the development of wave resources in China,is the focus of our research.The research group has done a lot of optimization design in the aspect of cantilever oscillating float wave energy conversion device and arrayed it.On this basis,it is necessary to further optimize the design of wave energy conversion device array to increase its wave energy capture capacity.Firstly,this paper summarizes the research progress of oscillatory floater wave energy conversion device,and summarizes the research progress of single device and array modeling technology of wave energy conversion device.For the arrangement of rectangular array floats distributed on both sides of the platform,we propose an improved scheme,and try to use the circular array floats.Under the condition of ignoring the central platform,we compare the power output and the interaction effect between the rectangular array floats and the circular array floats,and verify the superiority of the circular array floats Sex.On the basis of selecting the circular array as the analysis object,the research group proposes a cantilever oscillating float wave energy converter with multi float array based on the floating platform of wind wave integrated power generation system.The direct matrix interaction theory is used to evaluate the performance of the proposed array and perform layout optimization.Using FLOW-3D software,based on the layout optimization of the improved scheme,the platform is introduced into the simulation model,and the more appropriate parameters of the circular array are selected,and then compared with the rectangular array to verify the superiority of the improved scheme.
