Abstract:The transient stability of grid-connected wind farm with doubly-fed induction generator(DFIG) type and tran-sient characteristics of DFIG are analyzed.Wind turbine models and generator dynamic models of DFIG are established.The stator active and reactive powers decoupled control are implemented by modeling rotor-side converter,and the DC link voltage between converters is kept constant and adjust output reactive power by the grid-side converter vector con-trol strategy.The impacts on the power system and wind generator of DFIG of type when the three short-circuit faults occurring in the power system are studied by simulation,the results can offer references for constructing large capacity wind farm with DFIG type.
Keywords:wind farm  doubly-fed induction generator  converter  transient stability
