摘要
According to the working principle of the overtopping wave energy converters and the oscillating body wave energy converters, we designed a new type wave energy converter (WEC) and conducted the model study of the new floating-buoy WEC. The buoys move up and down with waves so that the electric energy can be constantly extracted from the wave energy. The buoys are important for the whole floating-buoy WEC. In this paper, three different shapes of the buoys and several mass blocks were designed to study the effect of the different shapes and the draught height of the buoys on the performance of the WEC. The flow rate within the pipes, the water volume in the reservoir and the power-capture efficiency were measured. Compared to the angle of the buoys, the height of the buoys are more significant to the flow rate within the pipes, the water volume in the reservoir and the power-capture efficiency. As the draught height of the buoys increases, the flow rate in the pipes increases. #3 buoys performed better than the #1 and #2 buoys. With #3 buoys, a maximum power-capture efficiency achieves 73.55%, at conditions of a 190mm wave height, a 3.33s wave period, and buoys with draught height of 41mm. © 2019 Chin. Soc. for Elec. Eng.
