Abstract

In this study, the analyzed turbine is a 5MW upwind-type wind turbine. This conceptual model was made to compare the results of the numerical analysis program in the IEA Annex23 Subtask2 OC3 project. The numerical analysis program used in this study is FAST developed by NREL and AQWA of ANSYS. Motion characteristics, such as RAO, average motion, significant motion and average amplitude of 1/10 highest motion were obtained through the numerical analysis. The results of the numerical analysis were compared with the results of other numerical analyses and the experimental results, and all the results agreed with one another. The results will help resolve the fundamental design trade-offs between basic floating system concepts.

이 연구에서는 부유식 풍력발전기 콘셉트모델중의 하나인 5MW급 OC3-Hywind를 해석하였다. 이 모델은 스파형 플랫폼을 가지고 있으며 3개의 현수식 계류삭으로 해저면과 연결되어있다. 수치해석프로그램으로는 NREL에서 개발한 FAST와 AQWA가 사용되었다. FAST에 입력되는 유체력은 AQWA를 통해서 계산되었으며, 운동특성으로는 전달응답함수와 평균운동, 상위1/3운동, 상위1/10운동을 평가하였다. 다른기관의 해석, 실험결과와 비교하였으며, 이 결과는 부유식풍력발전기 컨셉모델의 기초설계를 재해석하는데 있어 도움이 될것이다.
