Abstract :
In this paper, sub-synchronous resonance (SSR) damping in a doubly-fed induction generator (DFIG)-based wind farm using thyristor controlled series capacitor (TCSC) is studied. An SSR damping controller (SSRDC) is designed for the TCSC using the observed-state feedback method. Model reduction is applied to obtain a lower order model for the power system under study in order to make the SSRDC design simpler and practical. The IEEE first benchmark model modified to include a 100 MW doubly-fed induction generator (DFIG) - based wind farm is employed as a case study. In this work, MATLAB/SIMULINK is used for eigenvalue analysis and PSCAD/EMTDC for time-domain simulations, respectively.
