| Abstract |
This paper demonstrated the dynamic behavior of DFIG wind turbine during grid balanced and unbalanced faults by
using simulation results, the effect of voltage sag on DFIG wind turbine is discussed through comparing of the various voltage sag depth in a type of fault lengthways and contrasting various fault type in the same voltage sag depth
horizontally. The response characteristics of DFIG wind turbine during PCC voltage sags are summarized by a typical example. Finally it is clear that some countermeasures on the rotor side convertor or the stator side must be taken into account for DFIG wind turbine ride through PCC extreme voltage sag. |
