Abstract
This paper proposes the use of a novel saturated amorphous alloy core-based fault current limiter (SAACFCL) to improve the LVRT capability of doubly-fed induction generator (DFIG) based wind energy systems, especially during voltage sag events. Compared to the traditional cores which are widely used in fault current limiter (FCL), amorphous alloy core possesses a very narrow B-H loop which indicates that the SAACFCL requires a smaller dc excitation current, and it will incur low core losses. Under normal conditions, this developed SAACFCL accomplishes low impedance and has a negligible impact on the network operation. During grid faults, a deep voltage sag causes large fault currents that de-saturate the SAACFCL core, increasing its impedance which limits the fault currents and improves the LVRT capability of DFIG systems. The SAACFCL is designed and characterized by ANSYS software. To validate the performance of the SAACFCL, a DFIG based system equipped with the SAAC ....
