초록

다중공진 파력발전체는 파랑의 공진현상을 복합적으로 이용하여 실해역의 평상파 내습시에도 파랑을 증폭시켜 효율적인 발전이 가능하다. 공진에 의해 파랑이 증폭될수록 다중공진 파력발전체의 발전 효율이 증가하며, 발전 효율이 최대가 될 수 있도록 공진부의 형상 최적화가 필요하다. 다중공진 파력 발전체는 항만 공진부와 수로 공진부에서 파랑을 증폭시키며, 본 연구에서는 수로 공진부의 길이, 위치 등 다양한 조건에서 CFD 수치실험을 수행하여 조건 별 상관성을 분석하고 수로 공진부의 최적 형상을 도출하였다.

Multi-resonance wave energy converter can generate efficient power generation by complexly utilizing the resonance phenomenon of waves even when waves propagate normally. As the wave is amplified by resonance, the power generation efficiency of the multi-resonance wave energy converter increases, and the shape of the resonance part needs to be optimized to maximize power generation efficiency. The multi-resonance wave energy converter amplifies waves in the seiche resonance part and the channel resonance part. In this study, CFD numerical experiments were performed under various conditions such as the length and location of the channel resonance part to analyze the sensitivity for each condition and derve the optimal shape of the channel resonance part.
