摘要: The hydrodynamic performance of a novel system, which integrates an oscillating buoy wave energy converter with a pile-restrained floating breakwater, is experimentally investigated in a 2-D wave flume. A current controller-magnetic powder brake system is used to simulate the power generation system. Results show that excellent wave attenuation performance and satisfactory capture width ratio of the integrated wave energy system can be achieved at certain ratios between the width of floating breakwater and the wavelength. The wave pressure at the bottom of the breakwater is measured for different values of the excitation current of the current controller, corresponding to the power-take off damping force. The experimental results show that the wave pressure amplitude is affected by the power take-off, and that the installation of a wave energy absorbing system may reduce the horizontal wave loads. Hence, the integration of a wave energy system with the floating breakwater may not only utilize wave energy in a cost-efficient way, but may also improve the breakwater performance and survivability. © Copyright 2016 by the International Society of Offshore and Polar Engineers (ISOPE).
