چکیده    Encountering series-compensated transmission lines, sub-synchronous resonance (ssr) may strike the power system by jeopardizing its stability and mechanical facilities. this paper aims to verify the capability of static synchronous series compensator (sssc) in mitigating the mechanical and electrical oscillations such as ssr in wind farm integrations. a wind turbine with a self–excited induction generator (seig) represents the wind farm and it is connected to the system through a transmission line compensated by a series capacitor. both the induction–generator (ig) effect and torsional interaction (ti) on ssr occurrence are examined. simulations are carried out using emtdc/ pscad on the ieee first ssr benchmark model along with a seig based wind turbine. also a fast fourier transform (fft) analysis is performed to determine the dominant torsional mode existing in the turbine generator system. the sssc impact on ssr mitigation is interrogated in various case studies. a sssc with a simple power flow control in its base case is first considered. it is shown that the sssc can damp the ssr even without any specific auxiliary controller. in the following the same sssc is shown to effectively damp ssr when equipped with an auxiliary ssr damping (ssrd) controller.
