摘要
针对目前已有的越浪式发电装置和振荡浮子式波浪能发电装置,设计研发一种新型浮筒式波浪能发电装置,并进行物理模型试验研究。浮筒随波浪上下运动,将波浪能转化为水势能,利用水轮机发电技术,产生稳定电能。基于波浪能发电装置中浮筒因素,研究不同浮筒形状及吃水深度对输水管道中流量、蓄水池中上水量及装置能量俘获效率的影响特征。结果表明:浮筒锥度和浮筒高度对输水管道中流量、蓄水池中上水量及能量俘获效率都有影响,其中浮筒高度的影响更为显著;随着浮筒吃水深度的增大,输水管道中流量有增大趋势;3号浮筒表现的性能更优于前2种浮筒,且在在波高为190mm,周期为3.33s,吃水深度为41mm时,能量俘获效率达到最大,此时效率为73.55%。
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 190 mm wave height, a 3.33 s wave period, and buoys with draught height of 41 mm.
