摘要

提出了一种利用液压水柱和液压活塞强迫谐波运动的压差海浪能转换器的概念。来自液压活塞的机械动力通过线性感应发电机转换为电能。根据波能转换器的设计尺寸和力学性能,推导了波能转换器的运动方程和产生的电功率。对系统的频率响应进行了数值模拟,对系统的时间响应采用简单的欧拉法数值模型进行了模拟。研究发现,该波能转换器的最大转换效率为27%,并且对在其固有频率附近的波的驱动具有快速的瞬态响应。高生存能力和减少视觉和水面冲击可能是这种设计概念的优势,因为所有机械部件都可以并入海底和海岸线。

A harmonic pressure differential wave energy converter

A pressure differential sea wave energy converter concept using the forced harmonic motion of a hydraulic water column and hydraulic piston is presented. The mechanical power from the hydraulic piston is converted to electrical power by a linear induction generator. The equation of motion, and electrical power generated are derived in terms of design dimensions and mechanical properties of the wave energy converter. The frequency response of the system is modelled numerically for a variety of wave frequencies, and its time response is modelled using a simple Euler method numerical model. It was found that the wave energy converter yields a maximum conversion efficiency of 27% and a prompt transient response to actuation with waves around its natural frequency. High survivability and reduced visual and water-surface impact are likely advantages of this design concept, since all mechanical components may be incorporated into the sea-floor and shoreline.
