Coupling Characteristics of DFIG-based WT Considering Reactive Power Control and Its Impact on Phase/Amplitude Transient Stability in a Rotor Speed Control Timescale

The transient stability issues caused by doubly fed induction generator (DFIG)-based wind turbines (WTs) are receiving increasing attention. The q-axis reactive power control (QCtrl), as an essential part of DFIG-based WTs, has a significant impact on its transient response. In this paper, the impact of QCtrl on the phase/amplitude transient stability of a DFIG-based WT-dominated system is analyze...
