Parameters impact on the performance of a double-fed induction generator-based wind turbine for subsynchronous resonance control

With increasing wind power in power systems, impact of subsynchronous resonance (SSR) on wind generator is of interest. This study presents the models of a double-fed induction generator (DFIG)-based wind turbine in a series-compensated network for SSR study. For DFIG (induction machine), the induction generator effect (IGE) is the most important factor of SSR. The control scheme for IGE is proposed in this study and the impact of the control parameters is also studied in detail. Eigenvalue analysis is conducted to study the impact of wind speeds, series compensation levels and control scheme on IGE phenomena. Time-domain simulations are performed in Matlab/Simulink to confirm the analysis.
