波浪能发电系统浮板的优化设计

Optimization Design of Floating Plate for Wave Energy Generation System

针对波浪能发电系统设计中浮板能量转换效率低的问题,基于海南省某地现有波浪能发电实验站的波浪能采集装置,采用Fluent软件进行建模仿真的方法对其进行优化设计,提出一种优化摆式浮板的设计方案。比较原浮板和优化浮板在吸收波浪水平方向动能的能力、能量损耗、浮板积水问题等方面的差异,结果表明这种优化的摆式浮板能成功实现浮板在收集波浪水平动能能力上的提升,并且解决浮板积水问题,减小能量损耗,从而提高浮板能量转换效率。

Aiming at the problem of low transformation efficiency of floating plate in wave energy system, Fluent is used to model and simulate the wave energy converter in the wave energy generation testing station in Hainan province, so that the device can be optimized. A solution of optimized floating plate is put forward. The original floating plate and optimized floating plate are compared in the aspects of wave energy absorption in the horizontal direction, energy dissipation and floating plate residual water. The results of simulation show that the optimized design has improved the ability of collecting wave horizontal kinetic energy, raising the conversion efficiency of the floating plate and reducing energy loss, thus improving the wave energy conversion efficiency.
