Investigation of Dynamic Loads in Wind Turbine Drive Trains Due to Grid and Power Converter Faults
Energies, 2021 Electrical faults can lead to transient and dynamic excitations of the electromagnetic generator torque in wind turbines. The fast changes in the generator torque lead to load oscillations and rapid changes in the speed of rotation.
