Abstract-- This paper addresses implementation issues associated

with a novel damping control algorithms for STATCOM and

SSSC (static synch ronous series com pensator) in a series

compensated wind park for mitigating SSR (subsynchronous

resonance) and damping power system oscillations. The IEEE

first benchmark model on subsynchronous resonance is adopted

with integrating aggregated self-excited induction generator

based wind turbine to perform the studies. The potential

occurrence and mitigation of the SSR caused by induction

generator effects as well as torsional interactions, in a series

compensated wind park are investigated. The auxiliary

subsynchronous damping control loops for the STATCOM and

SSSC based on a novel design procedure of nonlinear

optimization are developed to meet the damping torque in the

range of critical torsional frequencies. The performances of the

controllers are tested in steady state operation and in response to

system contingencies, taking into account the impact of short

circuit ratios (SCRs). Simulation results are presented to

demonstrate the capability of the controllers for mitigating the

SSR, damping the power system oscillation and enhancing the

transient stability margin in response to different SCRs.
