Dynamic Properties and energy Conversion Efficiency of A Floating Multi-Body Wave energy Converter

引用

China Ocean Engineering 2018年第3期32卷 347-357页

作者： YANG Shao-hui WANG Yong-qing HE Hong-zhou ZHANG Jun CHEN Hu College of Mechanical and energy Engineering Jimei UniversityXiamen 361021China key laboratory of energy Cleaning utilization and Development of fujian Province Xiamen 361021China key laboratory of Ocean Renewable energy Equipment Fujian Province UniversityXiamen 361021China

The present study proposed a floating multi-body wave energy converter composed of a floating central platform,multiple oscillating bodies and multiple actuating arms. The relative motions between the oscillating bodies and the floating central platform capture multi-point wave energy simultaneously. The converter was simplified as a forced vibration system with three degrees of freedom, namely two heave motions and one rotational motion. The expressions of the amplitude-frequency response and the wave energy capture width were deduced from the motion equations of the converter. Based on the built mathematical model, the effects of the PTO damping coefficient, the PTO elastic coefficient, the connection length between the oscillating body and central platform, and the total number of oscillating bodies on the performance of the wave energy converter were investigated. Numerical results indicate that the dynamical properties and the energy conversion efficiency are related not only to the incident wave circle frequency but also to the converter’s physical parameters and interior PTO coefficients. By adjusting the connection length, higher wave energy absorption efficiencies can be obtained. More oscillating bodies installed result in more stable floating central platform and higher wave energy conversion efficiency.
