Popis: This paper discusses the influence of Accelerating power input Power System Stabilizer (PSS) and Supplementary Modulation Controller (SMC) for Static Synchronous Series Compensator (SSSC) on the system stability of a single-machine infinite bus system. The objective of the work presented in this paper is to design a robust PSS with accelerating power input and a robust Supplementary Modulation Controller for SSSC to damp low frequency oscillations arising out of small and large disturbances by placing all the eigen values within a specified contour in the s-plane. The selected input signal for the PSS is devoid of many disadvantages that the usually chosen speed input signal has. The control signal for SMC of SSSC used is Thevenin angle and is obtained by using the current through the line where the SSSC is installed. For tuning the controller parameters a nonlinear constrained optimization technique is used with the objective of damping oscillations to make the controller robust for a large range of operating conditions. The design of SMC is validated by performing nonlinear simulations for small and large disturbances.
