Modern wind turbines operate with variable speed and most of them are based on doubly fed induction generators (DFIG), with a back-to-back power converter. During voltage dips, the stator terminals can cause overcurrents in the rotor windings, which could threaten the converter integrity. The use of crowbar systems is the most common technique to avoid this situation. The crowbar activation disables...
At the present time, the wind power is one of the most accepted renewable energy sources and its penetration in electrical power systems has increased considerably. The high penetration of wind power influences the electrical power system performance. In this paper the behavior of a transmission system with a high level of wind energy penetration using doubly fed induction generator (DFIG) based wind...
