Experimental study on performance of breakwater integrated with oscillating water column wave-energy converter

为了考察防波堤兼作振荡水柱波能装置的实际发电性能,构建了物理模型并开展水工试验,试验中采用空气透平作为能量转换部件,并连接发电机,在不同入射波浪条件下,考察了装置的发电出力情况。研究结果表明:波浪周期对防波堤兼作振荡水柱波能装置的能量转换性能有较大的影响,长周期波浪作用下,装置的波电能量转换效率较高;当入射波波高较小,波浪条件较差时,装置的能量转换性能较弱。

To investigate the operating performance of breakwater integrated with an oscillating water column wave-energy converter, a model experimental study was performed in the wave flume. An air turbine and an electric generator were used for converting pneumatic power to electricity. Performances of the device under different incident wave conditions were examined. The results show that the wave period has a considerable effect on the performance of breakwater integrated with an oscillating water column and the device shows better performance under long wave period conditions. The device represents low energy conversion efficiency when the incident wave height is small.
