Abstract:To limit the current in stator and rotor circuit is a key technology for the low-voltage ride through(LVRT) of the double-fed wind power generating system.An active rotor crowbar circuit is used for limiting the over current in the rotor.This paper uses DFIG to establish.a simulation model for the wind power system and carries out simulation analysis based on PSCAD/EMTDC.The simulation results show that the active rotor crowbar circuit for the LVRT of the wind power system is effective.
Keywords:doubly fed induction generator  low-voltage ride through  crowbar circuit  PSCAD
