|a Sažetak na hrvatskom: Vjetroturbina je stroj koji pretvara kinetičku energiju vjetra u mehaničku energiju vrtnje. Postoje vjetroturbine različitih izvedbenih oblika. Vjetroturbina je ujedno i vrlo složen stroj izložen stalnom dinamičkom opterećenju (navale vjetra) tokom rada te njegove dinamičke karakteristike treba uzeti u obzir kod samog dizajniranja. Dinamičku analizu provodimo koristeći aeroelastične simulacijske modele. Današnji simulatori su vrlo moćni i daju vrlo vjerne simulacije stvarnih vjetroprilika i ponašanja analiziranog sustava koristeći veliki broj različitih varijabli. FAST je aeroelastični simulator za izradu aeroelastičnih modela vjetroagregata sa horizontalnom osi vrtnje. U ovom radu opisan je postupak modeliranja vjetroturbine i postavljen je model megavatnog vjetroagregata. Za simulaciju i modeliranje korišten je FAST i drugi pomoćni alati : AeroDyn, BModes, TurbSim. FAST modelira vjetroturbinu kao kombinaciju krutih i elastičnih tijela. Dobiven simulacijski model validiran je usporedbom karakteristika vladanja istog modela u GH Bladedu.

|a Sažetak na engleskom: Wind turbine is a device that converts kinetic energy of the wind into electrical power. There are many different types of wind turbines. Wind turbines are very complex machines that operate under continuous and intricate environmental dynamic loading insight in the turbine’s structural dynamic behaviors essential to their design and operation. These dynamics are analyzed using aero-elastic simulation models. Wind turbines are structures in motion and as such are not easily modeled. Modern wind turbine simulators are powerful and can accurately simulate many different variables.In this paper is used FAST for simulation and modeling of wind turbines and other tools. FAST is an aero-elastic simulator, developed by Jonkman, Buhl, and others at the NREL in Boulder, Colorado, designed to predict loads on horizontal-axis wind turbines.
Four such tools are used in this thesis: Modes, TurbSim, AeroDyn and FAST. The Modes is used to find the mode shapes of towers and blades, which are then used by Aerodyn and FAST. TurbSim is used to generate turbulent wind data sets:AeroDyn does aerodynamic calculations, and FAST uses those calculations to calculate many different loads on a HAWT. FAST considers the blade and tower to be flexible elements modeled. The blades are aerodynamically modeled to achieve lift when the wind hits them. Tower is also modeled as flexible multi-body entity. This paper presents how to model wind turbine in FAST and procedures for wind turbine model simulation. The FAST code models thewind turbine as a combination of rigid and flexible bodies what results with trustworthy model.The obtained model is validated in GH Bladed.
