The behavior of VSCF Doubly Fed Induction Generator (DFIG) during symmetrical grid fault is proposed in this chapter. The equivalent model of DFIG wind turbines in synchronous speed w1 coordinate system is given, thus design the network side, the rotor side Pulse Width Modulation (PWM) converter of directed d-axis voltage (or flux) with vector control program, and to improve it to meet for the operational control requirements of DFIG wind turbine under the grid voltage sags with mild conditions. Its simulation results show that the improved control scheme provides the system with a better ability to run uninterrupted.
