摘要
为了设计适用于浮式防波堤的波浪能发电装置,提出一种跷跷板式双浮筒型的装置方案,由水面双浮筒浮体和深潜水下的垂直阻尼板、连杆和PTO系统组成。利用水动力分析软件ANSYS-AQWA进行数值计算,在波浪侧向入射的工况下,分别研究自由漂浮和悬链锚固下的运动响应,研究3种海况下的轻重浮体在不同阻尼系数下的获能性能,以及型宽对获能性能的影响。结果表明,型宽对于获能性能具有较大的影响,半波长为最佳的型宽尺寸,发电装置在长波条件下也具有较强的发电能力。
In order to design a wave energy converter(WEC)that is applicable to floating breakwaters,a seesaw-type double-pontoon form WEC is proposed independently.It is composed of double floating pontoons,a deeply submerged vertical damping plate,a connecting rod and a PTO system.ANSYS-AQWA is utilized to carry out numerical simulation,the motion response under free-floating state and catenary moored state under oblique incident wave is studied accordingly,energy capture performance of light and heavy floating body under 3 different sea states and different damping coefficients is analyzed,and the effect of body breadth on energy capture performance is investigated.Results show that body breadth has significant effect on energy capture performance,half wavelength is the optimal body breadth size,and the converter has strong power generation capability in long wavelength states.
