PROJECT TITLE :
Transient Stability Enhancement of Doubly Fed Induction Machine-Based Wind Generator by Bridge-Type Fault Current Limiter
Transient stability could be a major concern for doubly fed induction machine (DFIM). A DFIM-based mostly wind generator is instantly plagued by faults at the grid side as its stator windings are interfaced to grid. But, the wind generators want to remain connected and continue operation during faults at the grid side in keeping with the grid code necessities. Therefore, it is important to enhance the transient stability of the DFIM-based mostly wind generators. To realize enhanced transient stability of the DFIM, a bridge-type fault current limiter (BFCL) is proposed during this study. Symmetrical along with unsymmetrical faults were applied to the test system to check the efficacy of the BFCL in transient stability enhancement. Simulations were administered in Matlab/Simulink environment. To demonstrate the effectiveness of the proposed BFCL, its performance is compared with that of the series dynamic braking resistor (SDBR). Simulation results show that the BFCL is a terribly effective device to attain better stabilization of the DFIM and outperforms the SDBR in all aspects.
