Impact of Increased Penetration of DFIG Based Wind Turbine Generators on Rotor Angle Stability of Power Systems

  title={Impact of Increased Penetration of DFIG Based Wind Turbine Generators on Rotor Angle Stability of Power Systems},
  author={D. Gautam},
i ABSTRACT An advantage of doubly fed induction generators (DFIGs) as compared to conventional fixed speed wind turbine generators is higher efficiency. This higher efficiency is achieved due to the ability of the DFIG to operate near its optimal turbine efficiency over a wider range of wind speeds through variable speed operation. This is achieved through the application of a back-to-back converter that tightly controls the rotor current and allows for asynchronous operation. In doing so… Expand
