کنترل سازه ای و تحلیل خستگی توربین بادی پایه کششی شناور فراساحلی با استفاده از میراگر جرم تنظیم شونده

As wind power continues its rapid growth worldwide, Offshore Wind Turbines (OWTs) are likely to comprise a significant portion of the total production of wind energy. These kinds of wind turbines cause of their placement environment should resist in great stormy conditions, which cause fatigue failures. Fatigue loads are one of the main failure reasons in offshore structures. One of the best ways for decreasing these kinds of loads is reducing the structure vibration. In this research application of a tuned mass damper with different masses, in an offshore Tension Leg Platform (TLP) is investigated. Tuned Mass Dampers (TMDs) modeled in a developed code FAST-SC. Results show that using TMD in the nacelle can reduce the moments in the base of the tower and turbine vibration. This reduction can also increase time until failure factor of the OWTs.
