摘要

In this paper, a non-linear controller based new bridge type fault current limiter (NC-NBFCL) is proposed to augment the transient stability of the doubly-fed induction generator (DFIG) based 20 MW wind farm (WF), and observed improved voltage profile with minimized fault current during the fault. The performance of the proposed NC-NBFCL is compared with the series dynamic braking resistor (SDBR) and static var compensator (SVC) in order to show the effectiveness of the proposed NC-NBFCL in terms of transient stability enhancement of DFIG based WF. In this work extensive simulations were executed in Matlab/Simulink software and in simulation, a temporary balanced and unbalanced faults were applied in the DFIG based tested model system to examine the transient stability improvement performance of the proposed NC-NBFCL. From all simulation results, and numerical analysis, it was found that the NC-NBFCL augments the transient stability of the DFIG based WF and outperforms the SDBR and SVC performances in all aspects.
