Experimental Research on LVRT Capability of DFIG WECS during Grid Voltage Sags

Low voltage ride through capability of DFIG wind energy conversion system had been paid much attention. The steady-state model of DFIG is discussed first, then the dynamic model is analyzed which considers transient current in stator side during voltage sags. To implement the LVRT capability of DFIG wind turbine, a method integrating rotor active crowbar… (More)
