Abstract

In this study, numerical investigations of the performance, wake and control-strategies of an optimized wind turbine were performed. These investigations delivers an intensive insight of the wind turbine operation under different control strategies. Further, wake analysis has been validated with existing experimental data. The wind turbine was analyzed by the 3-D steady state CFD simulations of Star CCM+ and by using of two CFD configurations. These are wake and pitch models. The first is used for the wake analysis at the design velocity, where-as the second, which is constructed of the overset technique, is applied for the pitch-control strategy. The overset mesh technique was adapted in the pitch model to overcome the com-putational domain with overlapping grids. The main advantage of the overset is to facilitate the computational time and effort in investigating the pitch control-strategy, since the pitch angle is prone to variation within a range of operating speed. Thus, it is possible to predict the performance and show a constant output rated power. The wake analysis results show agreement with the experimental data.
