Resumen:
During the planning process of a wind farm, an important aspect to be studied is
the best use of the available area. However, an increased number of wind turbines leads
to a reduction of the distances between each wind turbine, causing a significant drop in
the park’s globlal production due to the track effect. In this context, this paper presents a
study case of wind farms layout in northeast Brazil, where considering the preferred
wind direction, the wind turbines characteristics and their positions, the minimum
distances that must exist between the turbines are analyzed (in the perpendicular
direction of the wind and the prevailing wind direction) to mitigate the treadmill effect.
Initially, data describing wind energy development in Brazil and worldwide is
presented. Then concepts related to the study of winds, wind turbines and the treadmill
effect are elucidated. Subsequently the main factors that influence the design layout of a
wind farm are presented. Finally, the case study parks are presented, with their
respective results and evaluations.
