Abstract

The application of thyristor-controlled phase-shifters for damping power system oscillations as a result of small signal perturbations is studied. A simple method for detailed representation of phase-shifters in the studies of power system dynamics is presented. The method is based on the calculation of the complex torque coefficient. The proposed method is used to study and to optimize the parameters of the control system of a phase-shifter, for damping subsynchronous resonance (SSR) in AC systems. The studies are performed on the first IEEE benchmark of SSR. The analytical results are verified by detailed digital computer simulation studies, using the BPA´s Electro-Magnetic Transients Program (EMTP).
