Development of Gas-Liquid Two-Phase Wave Power Generation System

Abstract

In a previous report, we proposed a new type of offshore floating wave power generation system and predicted its characteristics through model analysis. This device generates electricity by reciprocating water in a tank mounted on a floating structure through the oscillation of the floating structure caused by waves. In order to improve the power generation efficiency, it is necessary to match the period of the reciprocating main stream with the period of the oscillation of the floating body caused by the waves, and to keep the turbine rotating continuously. This paper reports on a method of controlling the reciprocating water flow period that was studied to improve the performance of this device.
