Enhancement of Fault Ride-Through Capability during Symmetrical Fault of the DFIG Wind Turbine using Alternative Resistive-type SFCL [PDF]

open access: yes, 2018
In this paper, the resistive-type superconducting fault current limiter (RT-SFCL) with doubly-fed induction gen¬erator (DFIG) based wind turbine has been proposed to suppress the steady-state and transient fault current at stator side to improve the ...
