Abstract

As a result of the exhaustion of fossil fuel, interest about renewable energy is increasing day by day. Inter alia, study for wave power energy of which the calculability is high and the available amount is abundant is going along actively. As a float-countweight wave energy converter is equivalent improved structural strength compared with oscillating body type. we made the wave only in order to up and down motion by setting up bulkhead which is called wave camber at the outside of float. This paper mainly focuses on generation amount of plural connected float-counterweight wave energy converter and we calculate the amount. The result, we confirmed that the more a numerical value of nl/L increases, the more amount of electricity rises and also when it is over nl/L=0.40, it is possible to get continuous generation. Through this study, we can use as basic data for design of wave chamber on advantageous condition at the real seas and by way of estimation for generation amount.

화석 연료의 고갈로 인해 신재생 에너지에 관한 관심이 날로 증가하고 있다. 그 중에서도 예측가능성이 높고 이용 가능한 양이 풍부한 파력에너지에 관한 연구가 활발히 진행되고 있다. 부유체-균형추식 파력발전장치는 진동 타입과 비교해 구조 강도가 증진된 장치이며, 부유체의 포면에 웨이브 캠버라 불리우는 격벽을 설치하여 파도가 오직 상하운동만을 하도록 만들었다. 본 논문은 주로 병렬 연결된 파력 발전장치의 발전량에 중점을 두고, 그 발전량을 계산하였다. 그 결과, nl/L의 값이 증가할수록, 더 많은 전력량이 발생하고, nl/L=0.40 이상이 되었을 때, 상시 연속적인 발전량이 얻어진다는 것을 알 수 있었다. 이 연구를 통해서, 실제 해역 조건에 유리한 유수실을 설계하는데 기본 자료로 활용할 수 있다.
