Rotor overcurrent suppression strategy for doubly-fed induction generator based on vector PI controller under grid voltage faults

When a grid fault causes voltage sag, the rotor circuit of the doubly-fed induction generator (DFIG) may experience overcurrent, posing a threat to the safe operation of the converter. The research establishes a mathematical model of the DFIG under grid voltage sag conditions, analyzes the mechanism...
