Abstract :
    In turbines of variable speed systems, the turbine wind turbine absorbs wind power mechanical velocity by changing its velocity, and the output power curve is smoother, which helps improve power quality, but Since variable velocity generates variable frequency voltages, frequency stabilization should be used with electronic power converters, while fixed speed systems can be optimized at a specific wind speed. Variable velocity variable speed systems, with constant speed and constant torque function, have variable speed and constant torque. This superior feature of variable speed systems, despite the increased losses caused by power electronics and their high cost and the probability of structural resonance, has led to the rapid replacement of variable speed turbines by fixed speed turbines. Since controlling systems play a very important role in today s modern wind turbines, we investigate the behavior of wind turbine generator induced two-way power in Fault conditions without interfering with the protective scheme, the induction generator control system We describe the vector control method and simulate and analyze the behavior of this kind of generator using the Dynamic Voltage Recovery Protection Design by Simulink Matlab, which can be confirmed by increasing the stability of the farm and the network.
