跷跷板式波浪能装置阵列发电性能分析

The performance of seesaw type wave energy converters array

波浪蕴含着巨大的能量,也具有较大的破坏作用。提出了一种跷跷板式的波浪能发电装置,采用双浮筒型的水面浮子结构形式,在水下设置垂直阻尼板。波浪激励浮子产生横摇运动,利用浮子与水下阻尼板的相对摇荡运动发电,结构简单,运行可靠。利用ANSYSAQWA水动力分析软件计算了标准单体、大面积单体和多体阵列的发电性能,结果显示,在周期6.28 s,波高2 m的海况下,跷跷板装置具有每平方米上百瓦的发电能力,具有显著的应用前景。

The waves contain a enormous energy for exploitation and also invove great forces for destruction.A seesaw-type wave energy converter is proposed for exploitation of the huge energy,with a double-pontoon floater structure,and a vertical damping plate underwater.Waves drive the floater to produce a roll motion,and the relative rotation motion of the floater and the underwater damping plate is used to generate electricity.The structure is simple and reliable.The ANSYS-AQWA hydrodynamic analysis software is used to numerically calculate the power generation performances of the standard module,the large-area modules and the multi-body arrays.It is shown that with the linear wave of 6.28 s in period and 2 m in wave height,the seesaw device generates a power over one hundreds of watts per square meter,and could be adopted in many applications.
