ABSTRACT A dynamic braking resistor control strategy has been proposed to
damp the slowly growing subsynchronous resonant frequency oscillations.
It employs generator speed variation, rotor angle and power variation
signals to switch in braking resistors at the generator terminal. The
proposed control has been tested on the IEEE second benchmark model for
subsynchronous resonance studies. The dynamically switched braking
resistors have been found to control the unstable modes very
effectively. The control algorithm is simple and its realization will
require very little hardware

    ABSTRACT: This paper presents a new concept for damping electro-mechanical oscillations in large turbo generator. The proposed concept is based on coordination between Power System Stabilizer (PSS) and Thyristor Controlled Braking Resistor (TCBR). This coordination will enhance the stability of the inertial and torsional oscillatory modes. The study is performed on system-1 of the second IEEE benchmark for simulation of Sub-Synchronous Oscillations, using eigenvalue analysis and verified by detailed digital simulation. A dynamic fundamental frequency model for TCBR is developed. The pole placement technique is used to design the control system of TCBR and PSS. The shaft torque's following a disturbance is computed and analyzed. The obtained results indicate that substantial damping is achieved by the proposed coordination.

    ABSTRACT: This paper presents a method for damping torsional oscillations in large turbo generator using thyristor controlled braking resistor (TCBR). The study is performed on system-1 of the second IEEE benchmark for simulation of sub-synchronous oscillations, using eigenvalue analysis and verified by detailed digital simulation. A dynamic fundamental frequency model for TCBR is developed. The pole placement technique is used to design the control system of TCBR. The shaft torques following a disturbance is computed and analyzed. The obtained results indicate that substantial damping is achieved not only for the torsional oscillatory modes but also for the inertial mode by using the proposed control system.
