Transient Modeling and Postfault Stability Analysis of GFM-DFIG Considering Rotor-Side Current Limitation
This letter establishes transient models of currentlimited grid-forming doubly-fed induction generator (GFMDFIG) that incorporate the dynamics of the voltage controller. Based on the switching logic between normal operation and current limitation, the impact of the saturated current angle (SCA) on the transient performance of the system is revealed. Theoretical analysis and experimental results demonstrate that GFM-DFIG exhibits three distinct transient behaviors after fault clearance, including withdrawal of current limitation, highfrequency oscillations, and remaining locked in saturation, which guides the selection of current limiting parameters.
