초록

본 연구에서는 부유식 풍력-파력 복합발전 플랫폼 안에 설치된 다수 파력발전기의 현 배치안을 부체 간의 상호 간섭효과를 고려하여 평가하였다. 다수 부체가 수면 위에 떠 있는 경우, 순수한 입사파와 함께 인접한 부체에 의해 발생하는 산란파와 방사파의 영향으로 인해 다수 부체 간의 상호작용 과정은 매우 복잡하다. 다수 파력발전기 배열에 따른 회절 및 방사 문제의 상호작용 해석을 위하여 고유함수전개법을 적용하였다. 해석해의 타당성을 검증하기 위하여 상용 프로그램인 WAMIT으로부터 계산된 수치계산 결과와 비교하였다. 다수 부체 간의 상호 간섭효과를 나타내는 q-factor를 이용하여 복합발전 플랫폼내의 24기 파력발전기의 현 배치안에 대한 전체 성능을 평가하였다.

In this study, the present deployment of the multiple wave energy converters (WECs) in a floating wind-wave hybrid power generation platform was estimated considering the interaction effect among WEC buoys. The interaction processes of multiple buoys were very complex, since scattered and radiated waves from each buoy affected the others in the array. The interaction analysis of the diffraction and radiation problem by the array of WECs was applied by matched eigenfunction expansion method (MEEM). The analytical solutions were compared with the results of numerical calculation based on WAMIT. The overall performance of 24 WECs installed in the hybrid power generation platform was evaluated by the q-factor representing the interaction effect among buoys.
