Research on Transient Stability for Wind Power System Based on PSAT

    Abstract
  •   Introduction   The paper aims to study the transient stability of the wind power system and that how the injection of reactive power to the wind power system affects the stability.
      Method  So we established the mathematic model of the wind power generator， the frequency converter， and a three-machine-nine-node power system model was constructed based on PSAT. We realized the the time simulation in condition of the three phase fault.
      Result  Then we get the voltage and power angel figure of direct drive wind power system，double-fed wind power system and constant speed wind power system under different bus short circuit fault time.
      Conclusion  It demonstrates that the wind power system has different stability based on different wind power generator， disturbance and duration.
