The participation of wind power in the energy mix of current power systems is progressively increasing, with variable-speed wind turbines being the leading technology in recent years. In this line, dynamic models of wind turbines able to emulate their response against grid disturbances, such as voltage dips, are required. To address this issue, the International Electronic Commission (IEC) 61400-27-1, published in 2015, defined four generic models of wind turbines for transient stability analysis. To achieve a widespread use of these generic wind turbine models, validations with field data are required. This paper performs the validation of three generic IEC 61400-27-1 variable-speed wind turbine model topologies (type 3A, type 3B and type 4A). The validation is implemented by comparing simulation results with voltage dip measurements performed on six different commercial wind turbines based on field campaigns conducted by three wind turbine manufacturers. Both IEC validation approaches, the play-back and the full system simulation, were implemented. The results show that the generic full-scale converter topology is accurately adjusted to the different real wind turbines and, hence, manufacturers are encouraged to the develop generic IEC models.

In this paper, torsional vibrations in a five-mass drivetrain of a doubly fed induction generator (DFIG)-based and a permanent magnet generator (PMG)-based wind turbine are investigated through simulations. The simulated model includes aerodynamics of a 750kW wind turbine, as well as the dynamics of the generator, gearbox, and back-to-back power converters. In this study, the effectiveness of a sliding mode based control scheme to damp the drivetrain torsional vibrations for the events of a voltage dip occurring on the power grid and a wind speed variation is presented. The simulation results demonstrate mechanical disturbances have similar impacts on the drivetrain of DFIG-based and PMG-based wind turbines. However, the back-to-back converters in a PMG-based wind turbine effectively isolate the effects of power oscillations on the drivetrain.
