Study on the damping of the wind energy conversion system

Abstract

"Wind force" is improved which people have used for long time ago. Recently, wind forces have been reconfirmed as important energy. There is wind energy conversion system which wind energy is efficiently changed into electric power. This system have been researched and developed. However, there are some problems in this system. This vibration which is generated in winds, earthquakes, and propeller rotation. May have the bad influence of storing up fatigue on the tower itself. In this research, it aims that safety of this system improves using dampers including masses, such as TMD (Tuned Mass Damper) and IMD (Impact Mass Damper) which is applied impact energy. We carried out analysis with simple model of wind energy conversion system during earthquakes and winds. The result of this analysis is reported in this paper.
