Abstract

In this paper, wave energy convertors which convert incident wave energy into electric power using floating light buoy are investigated. One-tenth models of a floating light buoy, straight line and seesaw type electric power plant are manufactured and tested in wave flume. In these systems, we measure the horizontal and vertical slope, generated current and power of buoy with different wave heights and periods. This was confirmed the capability of getting electric power, then we suggest further works to get more efficiency.

본 연구에서는 등부표를 이용하여 외해에서 입사되는 파랑에너지를 전기에너지로 변환시키는 파력발전 방식에 대하여 연구하였다. 등부표와 직선형과 시소형 자가 발전체를 1/10 축소 모형으로 제작하고, 파랑수조에서 실험을 실시하였다. 이러한 시스템에서 서로 다른 파고와 주기를 갖는 파랑을 대상으로 등부표의 수평 및 수직 경사, 발생 전류와 에너지를 측정하였다. 이를 통하여 전기 에너지 획득 가능성을 확인하였고, 차후 연구 과제를 제안하였다.
