Bridge-Type Fault Current Limiter to Improve the Transient stability enhancement of Doubly Fed Induction Machine based Wind Generator

Abstract

In this paper Transient stability is a major sympathy toward doubly fed induction machine (DFIM).A DFIM-based wind generator is promptly influenced by shortcomings at the network side as its stator windings are interfaced to grid. Be that as it may, the wind generators need to stay connected and proceed with operation during flaws at the grid side as indicated by the network code prerequisites. Along these lines, it is imperative to improve the transient soundness of the DFIM-based wind generators. To accomplish upgraded transient steadiness of the DFIM, a bridge type fault current limiter (BFCL) is proposed through FLC in this paper. Symmetrical as well as unsymmetrical faults were applied to test system efficiency of the BFCL in transient stability enhancement. Simulations were carried out in Matlab/Simulink environment. To demonstrate the effectiveness of the proposed BFCL ,its performance is compared with series dynamic braking resistor(SDBR). Simulation results of BFCL gives better stabilization of DFIM.
