Flexible AC Transmission Systems (FACTS) devices are used for controlling the power flow in transmission lines. Series FACTS devices like TCR and TCSC varies line reactance for the power flow control. In this paper, the design aspect of TCSC is discussed based on percentage of compensation and ratio between inductance and capacitance. The capacitance and inductive region of operation along with shift in resonance are analysed. Finally the impact of TCSC in the power system is analysed under the factors like Surge Impedance Loading (SIL) and stability. © Research India Publications.
