Abstract-- Sub-Synchronous Resonance (SSR)

oscillations in long transmission line brings to failure of

the turbine shaft. STATic COMpensator (STATCOM)

is a multifunctional FACTS device which its ability

depend on its location on transmission line. In this

paper, a controller is proposed and designed for

STATCOM in transformer bus to damping SSR in all

operation points. The controller is designed based on

speed deviation damping signal. In addition to SSR

damping, STATCOM implemented in the transformer

bus can control line active power and other dynamical

events such as first swing stability and power

oscillations. Eigenvalue analyses and nonlinear

simulations in PSCAD/EMTDC software are employed

to illustrate the performance of the proposed controller

and the STATCOM. Simulation results approve the

proposed scheme capability in SSR damping at different

level of series compensations of the transmission lines.
