Fault Ride-Through Enhancement of a 9 MW DFIG Wind Farm Using a Dual-Layer STATCOM and Multi-Tier Protection Scheme: Detailed and Reduced-Order Modelling
The doubly fed induction generator (DFIG) dominates the wind energy market, yet its direct stator-to-grid connection makes it vulnerable to grid faults, creating a tension between hardware self-protection and grid-code fault ride-through (FRT) compliance. This paper presents the modelling and FRT analysis of a 9 MW DFI...
