Abstract
Atmospherical wind wakes in wind farms can be the cause of efficiency loss, extra mechanical efforts, maintenance anticipation and component replacement. In this paper it’s presented a review of the recent studies that highlight the impact of these phenomenom and the strategies used to mitigate these negative impacts. Basic concepts are presented in order to have a better understanding about the issue, such as wind wake and wake steering effects. Wind wake analysis are also provided via LIDAR and SODAR data indirectly collected, whose results reinforce the idea of wind wake effects studies require precise models in order to preview the performance of wind turbines.
