Faculty of Electrical and Computer Engineering Shahid Rajaee Teacher Training University, Tehran, Iran


The effect of wind generator on sub-synchronous resonance (SSR) is being interested by increasing penetration of wind turbine in power systems,. Purpose of this article is to analyze SSR in a wind farm based on doubly fed induction generator (DFIG) which is connected to compensating series grid. A dynamic model for analysis of induction generator effect and Torsional Interaction (TI) has been utilized and simulated. The IEEE first benchmark model, is modified to include a 100 MW DFIG-based wind farm, is employed as a case study. three phenomena including a) series compensation level, b) the rotor speed, and c) effect of internal parameters of RSC controller on SSR are evaluated and the simulation results are analyzed.
