摘要：Doubly fed Induction generators are used commonly in variable speed wind energy conversion systems due to their high output energy. This paper analyzes the steady state of wind power systems based on doubly-fed induction generator when subjected to different voltage sags at grid and the various parameters undergoing variations due to this. PWM converters are used as excitation power supply source to the DFIG wind energy conversion system of VSCF, which join rotor to the used grid. To control the convertor rotor side, vector control scheme is used which is based on stator voltage strategy. The model based on this scheme is simulated with the help of MATLAB software.
