Abstract :
The paper presents the potential use of supplemental control of doubly-fed induction generator (DFIG)-based wind farms for damping subsynchronous resonance (SSR) oscillations in nearby turbine-generators connected to series capacitive compensated transmission systems. SSR mitigation is achieved by introducing a supplemental signal into the control loops of the DFIG voltage-sourced converter-based back-to-back. The validity and effectiveness of the proposed supplemental control are demonstrated on a modified version of the IEEE second benchmark model for computer simulation of subsynchronous resonance by means of time domain simulation analysis using the EMTP-RV program.
