Abstract
This paper presents the transient stability enhancement of Doubly-Fed Induction Generator (DFIG)-based wind energy systems through the implementation of a Resistive Fault Current Limiter (RFCL). DFIG technology has gained popularity due to its ability to efficiently harness wind energy under variable conditions. However, its vulnerability to faults, particularly during symmetrical and asymmetrical disturbances, poses significant challenges to grid stability. This study investigates various internal and external control strategies, highlighting the limitations of conventional methods. The RFCL is proposed as an effective solution to mitigate fault impacts and improve system resilience. Simulation results demonstrate that integrating the RFCL significantly enhances transient stability, outperforming traditional fault current limiting approaches. This research contributes to optimizing DFIG performance and ensuring reliable wind energy generation.
