Nowadays by changing the rules, according to a new code of networks, the integration of wind energy, wind turbine during a fault even when the voltage to zero, reducing the need for injection of reactive current (proportional to the voltage drop) network stay connected. However, a practical reality in the operation of the wind turbine converters, the converters connected to grid instability throughout the flow injection errors low voltage (close to zero) in many papers have been ignored. In this paper, unstable exchange network side wind turbines, for loss of synchronization (LOS) have been defined and are looking for a sustainable approach based on frequency control and phase-locked loop (PLL) is to control the phase and reactive current and Active injection errors during severe wind turbine to reduce the volatility and thus the stability of the network
