The paper presents a conventional damping scheme, the excitation control, to stabilize synchronous generator torsional oscillations that occur in a power system containing series capacitor compensation. The IEEE second benchmark model, system-1 is employed in this study. This system, consists of a synchronous generator connected to an infinite bus through two parallel transmission lines, one of which includes an adjustable series capacitor. A power system stabilizer (PSS), which is designed by using modal control theory, is installed in the excitation system to provide damping torque for the generator. The order to demonstrate the effectiveness of the damping enhance by the proposed controller, various test results, such as the torsional mode shapes, eigenvalue sensitivities for different operating conditions, and the real parts of torsional modes for distinct degrees of series compensation, are shown in this paper. In addition, dynamic responses of the nonlinear system under pulse torque disturbance are performed. It can be concluded from the simulation results that the proposed excitation controller can effectively stabilize the torsional oscillations.
