Abstract

This paper presents aerodynamic power outputs of wind turbine of 6 MW wind farm composed of 3 sets of 2 MW wind turbine according to the separation distance by using CFD. Layout design including offshore wind farm and onshore wind farm is key factor for the initial investment cost, annual energy production and maintenance cost. For each wind turbine rotor, not actuator disc model with momentum source but full 3-dimensional model is used for CFD and it has a great technical meaning. The results of this study can be applied to the offshore wind farm layout design effectively.

본 논문은 2 MW급 풍력터빈 3기로 구성된 6 MW 해상풍력발전단지의 풍력터빈 이격거리에 따른 공기역학적 출력 변화를 전산유동해석을 활용하여 연구한 것이다. 육상 뿐만 아니라 해상풍력발전단지에 있어서 레이아웃 설계는 풍력발전단지 초기 투자비, 년간 발전량 및 유지보수비에 영향을 끼치는 핵심 인자이다. 각 풍력터빈 로터에 대해서 모멘텀 소스를 가지는 액츄에이터 디스크가 아닌 완전한 3-D 모델에 대해서 전산유동해석 기법을 적용하여 연구하였으며 이는 기술적으로 큰 의미를 가진다. 본 논문의 연구결과는 향후 해상풍력발전단지 레이아웃 설계에 유용하게 적용될 수 있을 것이다.
