Abstract

This paper presents the results of a study on the application of shunt reactors for the damping of torsional oscillations that occur in a power system containing series-capacitor compensation. The IEEE Second Benchmark Model, system-1 is employed to investigate the benefits of the utilization of modulated reactive power in suppressing unstable SSR modal interactions. A set of shunt reactor is connected to the generator bus of the affected synchronous machine whose shaft is directly coupled to the turbine system of the benchmark model. In order to stabilize all the torsional modes, a unified approach based on modal control theory is proposed for the design of a shunt reactor controller, which is essentially a dynamic output compensator. For demonstrating the effectiveness of the damping enhanced by the proposed scheme, eigenvalue analysis for different loading conditions, and sensitivity analysis for controller parameters are performed. In addition, dynamic responses of the nonlinear system under a three-phase short-circuit fault at infinite bus are also carried out. It can be concluded from the simulation results that the proposed shunt reactor control scheme can effectively suppress the torsional oscillations.
