Thyristor controlled series compensator (TCSC) controller, are the type of flexible AC transmission system commonly known as FACTs. These are used to control the transmission line impedance by the thyristor-controlled capacitor in series introduced into the transmission line. Thyristor Controlled Series Compensator is used as compensator in transmission system. TCSC can control the power flow, to improve the transient stability and increase the transfer limits. These controllers provide a very response to increase the power by the mechanism of subsequent oscillations are damping. In this process quick changing of the equivalent capacitive reactance to the full compensation is achieved in the first few cycles after a fault. TCSC controllers are used for the compensation in transmission by variable impedance. The role of the compensator is mainly to mitigate the effects of voltage sag. In this paper the Simulation results represents a comparative study of output voltage and power stability across a three phase parallel load without and with Thyristor Controlled Series Compensator. The simulation was studied with help of model prepared by the Simulink in Matlab. The results showed that the proposed method of introduction of TCSC was efficient in mitigating voltage sags and improving the power quality of isolated power system.
