SIMULATION UNDER BALANCED GRID CONDITION
It is observed that the active and reactive powers supplied by the utility grid are decoupled and dc link voltage is maintained constant due to the control strategy made in the grid side converter. SIMULATION RESULTS UNDER VOLTAGE SAG CONDITION The simulation results under the voltage sag 80% of rated voltage is applied in the faulted period. The DFIG system produces active power of 1.4 MW which corresponds to maximum mechanical turbine output minus electrical losses in generator. When the grid voltage changes suddenly from its rated value i.e.415V the stator current as well as rotor current increases and the active power P suddenly oscillates between 0.8 MW to 1.4 MW.
