Study of Vibration of Dual-Buoy on the Linear Electrical Generator for Wave Energy Converter

Nguyen Hoang Quan | Tran Thanh Tung ^[2]

Abstract: Today, Ocean wave energy is a renewable energy source with a large potential to contribute to the worlds electricity production. This report presents the results on the modeling and optimization the systems of two buoys for wave energy converter. The first is a floater. The second is a semi-submerged body. The energy is converted from the relative motion between the two buoys by the linear generator. For simulation in three dimensions, the system of equations (6 modes of motions) has been obtained. The governing equations are solved by ANSYS AQWA software and Matlab tools. In this report, Response Amplitude Operators (RAOs) are analysed. Based on the RAOs results, we will determine the wave frequency domain for the maximum energy. The obtained results can be used for the simulation, calculation and geometry optimization of the more realistic system in wave energy convertion.
