정격풍속 이하에서 풍력터빈의 타워 섀도 추력 동하중 개발 = Evaluation of Thrust Dynamic Load under Tower Shadow in Wind Turbine below the Rated Wind Speed

다국어 초록 (Multilingual Abstract)

This paper relates to a method of modeling the thrust dynamic load caused by the thrust variation occurring on the blade due to the tower shadow below the rated wind speed. A method that uses thrust coefficient is presented by introducing “tower shadow coefficient of thrust variation”. For a 2MW wind turbine, the values of “tower shadow coefficient of thrust variation” are calculated and analyzed at wind speeds below the rated. The dynamic load model of thrust under tower shadow is evaluated in Matlab/Simulink using the obtained “tower shadow coefficient of thrust variation” and thrust coefficient. It shows that the thrust variations acting on the three blades by the tower shadow can be expressed using both the thrust coefficient and the introduced “tower shadow coefficient of thrust variation”.
