新型浮筒式波浪能发电装置试验研究
|
摘要
设计研发一种新型浮筒式波浪能发电装置,并对其进行试验研究。采用1∶16的缩尺比制作模型,通过不同输水管径及不同波浪条件的模型试验分别研究输水管径、波浪高度、波浪周期这3个因素的变化对新型波浪能发电装置输水流量、上水量、一二级能量俘获效率的影响特征规律,为实际建设波浪能发电装置提供可靠的设计依据。试验结果表明:随着输水管径的增大,流量、上水量、能量俘获效率呈一致增大的趋势;随着波高的增大,流量、上水量均有所增加,但能量俘获效率反而减小,而波浪周期的变化对三者的影响幅度较为稳定。该模型试验中,所设计新型浮筒式波浪能发电装置的俘获效率最高可达37%,证明新型浮筒式波浪能发电装置是一种具有竞争力的方案。
A new floating-buoy wave energy converter(WEC)is proposed and designed. A test study of the new floatingcylinder WEC was carried out. A model with 1∶16 scale was built and tested experimentally. The effects of pipe diameter,wave height and wave period on the performance of the water flow within the pipe,water volume in the reservoir and energy capture efficiency of the new floating-buoy WEC were researched which provides a reliable design basis for the construction of WECs. The results show that as the pipe diameter increases,the flow rate in the pipe,the water volume in the reservoir and the energy capture efficiency are increased. On the other hand,as the wave height increases,the flow and the water volume are also increased,but the energy capture efficiency is decreased. The change of wave period only has a small effect on the flow,the water volume or the energy capture efficiency. In model experiments,the energy capture efficiency of this new floating-cylinder WEC can be up to 37%,which is competitive with existing designs.
