Wind energy plays an increasingly important role in the world because it is friendly to the
environment. During the last decades, the concept of a variable-speed wind turbine (WT)
has been receiving increasing attention due to the fact that it is more controllable and
efficient, and has good power quality. As the demand of controllability of variable speed WTs
increases, it is therefore important and necessary to investigate the modeling for wind
turbine-generator systems (WTGS) that are capable of accurately simulating the behavior of …

This paper presents a vector control direct (FOC) of double fed induction generator intended
to control the generated stator powers. This device is intended to be implemented in a
variable-speed wind-energy conversion system connected to the grid. In order to control the
active and reactive power exchanged between the machine stator and the grid, the rotor is
fed by a bi-directional converter. The DFIG is controlled by standard relay controllers. Details
of the control strategy and system simulation were performed using Simulink and the results …
