The present study deals with the conceptual design of a motion reduction device for a floating wave-offshore wind hybrid power generation platform. A damping plate attached to the bottom of a column of a large semi-submersible is introduced to reduce the motion of the platform. Performance analyses ...

파력과 풍력을 동시에 발전하는 발전시스템의 대표적인 프로젝트에는 무엇이 있나? | 최근 해양에너지 발전시스템의 경제성 향상을 위하여 다수의 해양에너지원을 복합적으로 발전하는 시스템을 개발하려는 시도가 이루어지고 있으며, 계류계, 전력변환,계통연계, 이송/설치 등의 비용을 절약할 수 있는 시스템에 대한 연구가 이루어지고 있다. 특히 환경 적지가 일치하는 파력과 풍력을 동시에 발전하는 발전시스템의 개발 및 실해역 시험이 유럽을 중심으로 수행되고 있으며, MARINA platform project(Soulard et al., 2013), H2Ocean project(Palomar, 2013), P80(Yde etal., 2015) 등이 대표적이다. 국내에서도 선박해양플랜트연구소(KRISO, Korea Research Institute of Ships and Ocean Engineering)주관으로 2013년부터 2016년까지 부유식 파력-해상풍력 연계형 발전시스템 설계기술 개발에 대한 연구가 수행되었으며, 부유식 플랫폼에 다수의 풍력터빈 및 파력발전기를 탑재하고 통합전력제어시스템을 통해 복합 해양에너지원을 동시에 활용하고자 하는 발전시스템에 대한 개념설계가 완료되었다(Kim et al. | |
선박 및 해양구조물의 과도한 운동을 억제하기 위한 장치에는 무엇이 있나? | 선박 및 해양구조물의 과도한 운동을 억제하기 위한 장치들은 동조액체감쇠장치(Tuned liquid damper), 빌지킬(Bilge keel),핀 안정기(Fin stabilizer), 수평판(Horizontal plate) 또는 감쇠판(Damping plate), 트러스 폰툰(Truss-pontoon) 등 다양한 형태가 존재한다(Fig. 1). |
