Abstract

In this study, the dynamic modeling of floating offshore wind turbine system is reported and the dynamic behavior of the platform for the offshore wind turbine system is analyzed. The modeling of the wind load for a floating offshore wind turbine tower is based on the vertical profile of wind speed. The relative Morison equation is employed to obtain the wave load. ADAMS is used to carry out the dynamic analysis of the floating system that should withstand waves and the wind load. Computer simulations for four types of tension leg platforms are performed, and the simulation results for the platforms are compared with each other.

본 논문에서는 해상 부유식 풍력타워의 동역학 모델링이 제시되고, 다양한 해상환경하중인 풍하중, 파랑하중을 모델링하여 플랫폼의 동적 거동해석을 수행하였다. 풍하중을 모델링하기 위해 풍속은 높이에 따라 변하도록 고려하였고, 파랑하중은 상대운동 모리슨방정식을 이용하여 모델링 하였다. 동적 거동해석을 위해 동역학해석프로그램인 ADAMS 를 이용하였다. 부유식 플랫폼에 많이 쓰이는 tension leg platform 의 네 가지 타입에 대해 동적 거동특성을 비교하였다.
