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

Umesh Chaudhary, Jyotishman Pathak

Abstract


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 fault ride through (FRT) capability of the system. This fault current limiter utilizing the superconductor dc coil so there is not any power loss during both normal as well as faulty operation of system. The analytical analysis has been also presented. The simulation results of a 0.9 MW/0.69 kV, the DFIG-based wind turbine are obtained with and without proposed RT-SFCL using PSCAD/EMTDC software. Finally, it observed that the voltage sag at the generator terminal and consumption of reactive power from the grid has been reduced during symmetrical fault
