Enhancement of Transient Stability of Induction Generator Using Plugging Mode Operation
This paper deals with transient stability enhancement of grid connected squirrel cage Induction Generator. In
most of the wind power generation Induction Generator is widely use because of its reliability and low cost. Fault occurs in
power system, leads to over speed and voltage instability of induction generator. When the fault is clear rotor speed is high
that make system become unstable. For stability improvement, unique property of the induction machines in which direction
of the rotating flux is reversing employed. After clearing the fault operating mode of the induction machine is changed from
the generating to the plugging mode for a short duration of time. This shows that the proposed method can be effective in
enhancing the transient stability.
