Application of TC SC in Enhancing Dynamic Performance of Interconnected Multimac hine Power System

Abstract

TCSCs (Thyristor Controlled Series Capacitors) have been used by many modern electric power system utilities for regulating power flow and increasing power transfer capability. The ability in regulating the transmittable power flow also implies the potential application of the device for the improvement of system stability and dynamic performance. The research reported in this paper investigates the application of TCSC in improving dynamic performance of large interconnected electric power system. Simulation results show that the TCSC provides better system stability and dynamic performance. The results have also been verified through eigenvalues analysis and confirmed by time-domain simulations.
