随着对可再生能源期望的增加，人们正在研究波浪能的经济和环境效益。一种钟摆式波能转换器，在水室中诱发入射波，并且当入射波和反射波叠加时形成驻波。在驻波节点处安装一个摆板，它驱动与电力系统相连的发电机。本研究以二维模型试验来评估水室与摆锤系统的基本形状设计与波浪反应。通过改变波浪周期和波高，给出了固定模型水池的波浪响应和浮体模型的运动。一个电动机，作为一个负载系统的发电机与扭矩控制，连接到摆轴，以评估波能转换效率。从波能转换效率的角度比较分析了荷载和入射波条件（周期和高度）变化的影响。这些结果表明，一个更优化的设计与提高能量转换效率的钟摆波能转换器（WEC）。
With the increase in renewable energy expectations, wave-generated energy is being studied for its economic and environmental benefits. A pendulum wave energy converter induces incident waves in a water chamber and forms standing waves as the incident and reflected waves are superposed. A pendular plate is installed at the standing wave node and it drives an electric generator connected to the power system. In this study, two-dimensional model tests are conducted to evaluate the basic shape design and wave responses of a water chamber and pendulum system. The wave responses of the fixed model water chamber and the motions of a floating model are presented by varying wave periods and wave heights. An electric motor, acting as a load system of the generator with torque control, is connected to the pendulum shaft to assess the wave energy conversion efficiency. The effects of variations in load and incident wave conditions (period and height) are compared and analyzed from the viewpoint of wave energy conversion efficiency. These results suggest a more optimal design of a pendulum wave energy converter (WEC) with improved energy conversion efficiency.
