Abstract
In this paper we present experimental results concerning the impact of the chosen torque control gain on the deterioration of the drive-train in wind turbines. Here the deterioration is considered to be produced by the mechanical stress, on the drive-train, and it is measured as the dissipated power at this level. The wind turbine is assumed to be controlled, into the variable-speed region, by using the optimal torque control method, commonly used for maximum power tracking. In this work, we present and discuss the obtained results of produced energy and dissipated one (at the drive-train level), for different choices of the torque control gain under the presence of high turbulence intensity of the wind speed. The tests have been performed in simulation by using real wind-speed data and by a combined simulated drive-train and a real mini wind turbine available at GIPSA-lab.
