Transient stability enhancement of DFIG based 10 MW wind farm by using of new inductive bridge type fault current limiter

Due to numerous advantages of the doubly-fed induction generator (DFIG), the application of DFIG based wind generator (WG) is increasing very rapidly. However, the transient stability is one of the major concerns of the DFIG based wind generator. Therefore to accomplish this goal, in this paper, an existing non-linear controller based new inductive bridge type fault current limiter (NC-NIBFCL) is proposed to augment the transient stability of the DFIG based wind farm (WF), and its performance is compared with the existing series dynamic braking resistor (SDBR). In this work all simulations were executed in Matlab/Simulink software and in simulation, a temporary three-line-to-line (3LL) fault, and double-line-to-line (2LL) faults were applied in the DFIG based tested model system to examine the transient stability improvement performance of the proposed NC-NIBFCL. After simulation results, it is proved that the proposed method can improve the transient stability of DFIG based WF and performed well compared to SDBR.
