날개 요소 운동량 이론을 적용한 풍력 발전기 해석용 모듈 개발 연구

(Development of a module for wind turbine analysis applying blade element momentum theory)

Abstract :

In this study, a module is developed for modeling and analyzing dynamic behavior of a wind turbine using RecurDyn, which is a commercial multi-body dynamics software developed by FunctionBay Inc. The wind turbine consists of tower, nacelle, hub and three blades. Tower and blades are regarded as flexible bodies for considering elastic effect using beam theory and spring force. In this paper, a constant speed wind was assumed and aerodynamic force was modeled using blade element momentum theory. Dynamic analysis applying this aerodynamic force was carried out. To verify the validity of analysis results, these results are compared to those of GH-Bladed which is commercial software for analyzing wind turbine system distributed by Garrad Hassan.
