Optimized Design of Demagnetization Control for DFIG-Based Wind Turbines to Enhance Transient Stability During Weak Grid Faults
This letter analyzes the transient stability of DFIG-based wind turbines (WTs) with demagnetization control during weak grid faults. It is firstly pointed out that there exist transient instability issues, and the main influential factors (i.e., fault depth, short circuit ratio (SCR), and demagnetization coefficient) on stability have been revealed. On this basis, an optimized design of demagnetization control is firstly proposed for DFIG-based WTs to improve the transient stability during weak grid faults. Finally, the analysis and proposed method are validated by experiments.
