Abstract

In this paper application of voltage source inverter (VSI) based series compensator, known as static synchronous series compensator (SSSC), is studied. A power flow controller is designed for a 48-step SSSC. Small signal and large signal torsional characteristics of an SSSC compensated power system are studied. The effects of DC link capacitor of the SSSC on torsional modes are studied. An integral state feedback controller is proposed to improve the torsional characteristics of the SSSC. The torsional characteristics are studied through eigenvalue analysis and the results are validated through PSCAD/EMTDC simulation studies.
