Abstract
The friction presents several nonlinear characteristics becoming difficult its modeling. Also, its dynamic characteristics need to be planned or adequately compensated to reduce friction effects. This work presents a study of the starting performance of a horizontal-axis small wind turbine drivetrain, considering the friction phenomena of bearings typically used in wind systems. A theoretical mathematical analysis will be carried out, and a new dynamic model will be developed in order to consider the effects of static and dynamic friction on the behavior of wind turbines. The mathematical approach is compared using experimental data available in the literature.
