Simulation and Optimization Design of Large Wave Power Generation Device Based on Group Array Module

Based on the research achievements of the Haiyuan 1 oscillating buoy wave power generation device, this paper proposes the innovation about a group array of the buoy to increase the output of power generation and realize large-scale power generation. Firstly, the conversion efficiency of wave energy captured by buoys of arrays 3, 6, and 9 for power generation is theoretically estimated. According to wave theory, the energy conversion efficiency of buoy increases with the increase of array number. Then, the modeling and simulation of the buoy array wave energy generation system are carried out by using AMESim simulation software. Through the simulation and optimization of the parameters of the components in the array buoy storage power generation system, the stability and efficiency of the wave power generation device under different array buoys are studied. The simulation results show that by adjusting the volume of the accumulator, precharge pressure and the displacement of the hydraulic motor, the power generation system can not only realize the continuous power output, but also the power output increases with the increase of the number of accumulators. It is proved that the feasibility and rationality of the designed buoy power generation system in group array module, and the research results can make a reliable technical reference for the construction and implementation of large-scale wave power generation system.
