# Time-domain dynamic simulation of a wind turbine including yaw motion for power prediction. A new wind turbine simulation tool for a time-domain dynamic simulation was developed in this study. For the wind turbine model, the NREL 5MW reference wind turbine was used. Using measured data, the developed tool was applied to predict annual energy production from the wind turbine at four different sites in a complex terrain of Korea. The results were compared with those predicted by a commercial frequency-domain program widely used to predict the annual energy production from a wind turbine. Without a yaw control, the predictions from the proposed tool were close to those from the commercial wind farm design program. The results of this study suggest that the power production from a wind turbine can be predicted by the proposed time-domain wind turbine simulation tool with a proper yaw algorithm which is not available in commercial frequency-domain programs.

Dynamic overset CFD simulations of wind turbine aerodynamics Yuwei Li a,1, Kwang-Jun Paik a,2, Tao Xing b,3, Pablo M. Maxwell Stanley Hydraulics Laboratory, The University of Iowa, Iowa City, IA 52242, USA a r t i c l e i n f o Article history: Received 21 November 2010 Accepted 18 June 2011 Available online 18 July 2011 Keywords: Wind turbine aerodynamics Overset grids Rotor flow Computational fluid dynamics a b s t r a c t Simulations of the National Renewable Energy Laboratory (NREL) phase VI wind turbine using dynamic overset grid technology are presented. Computations of the effect of wind speed (5,10,15 and 25 m/s) at a fixed blade pitch angle of 3 with constant rotational speed using unsteady Reynolds-Averaged NaviereStokes (RANS) and Detached Eddy Simulation (DES) turbulence models, both showing little difference in the averaged forces and moments. The effect of angle of attack is evaluated by dynamically changing the pitch from 15 to 40 at constant wind speed of 15 m/s.
