Dynamic behaviour of two stator flux control systems of a doubly fed induction generator based grid-connected wind turbine during voltage dips

In order to investigate the dynamic behaviour of a wind turbine with Doubly Fed Induction Generator (DFIG) connected to the network during grid disturbance, this paper presents an equivalent continuous model. This model includes mechanical, electrical parts and the connection system to a distribution network. A comparison of two different DFIG control strategies during network faults is shown with the help of numerical simulation.
