Abstract

This paper proposed a pulley-buoy accelerated type linear wave power generation system, and verifies its feasibility and effectiveness through experiments. Compared with traditional three-phase wave energy converter, the process of energy transfer was cancelled in the pulley-buoy accelerated type linear wave power generation system, wave energy was converted into electrical energy through the movement of float directly. In the system, the pulley assembly increased the velocity of the float and the generating capacity of the linear generation system, thereby increasing its conversion efficiency. In the experiment, an undersized pulley-buoy accelerated type linear wave power generation system and a swing wave-making system were built in the laboratory. The experiment explored the influence of the number of the stator coil on the power generation performance of the system, and results showed that within the scope of this research, increasing the stator coils to a certain extent could effectively raise the efficiency of wave energy conversion and improve the generation performance of the pulley-buoy accelerated type linear wave power generation system. This research provides valuable experience for the actual application and effective operation of wave energy conversion system.
