Abstract

Turbulence is a phenomenon associated with the flow of wind in wind farms. It has a significant effect on the performance of wind turbines, causes a strong load on the blades and modifies the evolution of the profile of the wind speed in the increasing wake. In order to investigate this phenomenon and describe in a much more precise way the effect of wind turbulence on the produced power of a wind turbine, we present in this work, a study which aims at the effect of turbulence on a wind turbine in downstream in the wake of another front wind turbine, for a given wind farm. This study is based on the use of the complete Ishihara wake model which takes into account the ambient and generated wind turbulence and on the input of data and characteristics of the ENERCON E2 commercial wind turbine. The simulation results obtained from the power developed with turbulence have been presented and compared to those without turbulence.KeywordsTurbulenceWind farmIschihara Wake modelWind energyWind flow
