采用可再生能源中的波浪能为航标供电,是解决航标供能的有效方式。本文以为航标供电的振荡水柱式波浪能发电装置为研究对象,开展不同工况及负载对振荡水柱式波浪能发电装置转换效率影响的研究,确定最高效率下波浪能装置的各类参数值。通过物理模型试验结果表明,获得的最佳效率点在T=2.5s时,H=104mm,转换效率最大为35%。振荡水柱式波浪能发电装置的能量转换效率受负载影响较小,受波浪要素中波高和周期的影响较大,特别是受波高周期比影响较大。本试验结果对优化振荡水柱式波浪能发电装置的方向提供指导意义,有助于进一步研究。

Experimental Study on Conversion Efficiency of Wave Energy Powered Navigation Marks

That is an effective method to use wave energy to provide electricity power for navigation beacons, which can solve the energy supply of navigation beacons. This article researches the efficiency of the oscillating water column wave energy converter (OWC WEC) under different operating conditions and loads. Then it determines various parameter values of the WEC under the highest efficiency. The results of physical model tests show that the best efficiency is 35%, when wave period is 2.5s, wave height is 104mm. The energy conversion efficiency of the OWC WEC is less affected by the load, and more greatly by the wave height and period, especially by the wave height to period ratio. The result of this test provides guidance for optimizing the direction of OWC WECs, and is helpful for further research.
