A Study on Dynamic Motion and Wave Power in Multi-Connected Float-Counterweight Type of Wave Energy Converter

Abstract

Recently, with respect to structural strength and relevant analysis of a float-counterweight wave energy converter, it has been more improved than existing oscillating body type. this study is mainly focusing on dynamic motion and wave power generation of ‘multi-connected’ float-counterweight device by calculating the acquired generation amount. This advanced research based on the original float-counterweight device was conducted through the wave’s up and down motion by setting up bulkhead which is called wave camber. Most of all, it was obtained that the ‘multi-connected’ float-counterweight device would be more efficient and practical than the original one in terms of float displacement, wire tension and amount of wave power. Through this study, a basic data for design of wave chamber was utilized on advantageous condition under actual circumstances of the sea and then estimation of generation amount for the ‘multi-connected’ float-counterweight device was realized, compared to the original one.
