摘要

本文介绍了一种波能转换器(WEC)的实际设计。WEC是基于一种创新的机械装置动力输出(PTO),它可以通过一个浮动的浮标将波浪能转化为电能。WEC采用缆绳和滑轮机构,将海浪的双向运动转化为发电机的单向旋转,从而在浪涌和升沉两种模式下都能捕获波浪能量,从而实现高效率工作。首先给出了系统的结构,描述了系统的工作原理。在此基础上,对水动力进行了时域分析。此外,在Matlab/Simulink中对耦合力学和水动力模型进行了仿真,以验证所提设计的性能。仿真结果表明,所提出的WEC能够高效地吸收波浪能量,可以应用于实际工况。

A Study on Design and Simulation of the Point Absorber Wave Energy Converter Using Mechanical PTO
This paper presents a practical design of a wave energy converter (WEC). The WEC is based on an innovative mechanical device power take-off (PTO) which can convert wave energy into electric energy by using a floating buoy. By using cable and pulley mechanism, the WEC can work in high efficiency by capturing wave energy in both surge and heave mode and converting the bidirectional motion of ocean waves into one-way rotation of an electric generator. First, the configuration is presented to describe working principle of the system. Then, the hydrodynamic forces are analyzed in the time domain. Moreover, the coupled mechanical and hydrodynamic model are simulated in Matlab/Simulink to investigate the performance of the proposed design. Finally, simulation results indicate that the proposed WEC can absorb wave energy in high efficiency and can be applied in the realistic condition.
