In the last 20 year the power demand has increased rapidly. As the demand in power is increased, the expansion of the transmission line and generation facility is been severely limited. Due to this the transmission line are loaded heavily and the voltage stability become power transfer limiting factor. So to solve the various power system problem the flexible AC transmission system (FACTS) is been mainly used now a day. In this paper we have aimed towards the benefits of using the Thyristor controlled series capacitor (TCSC) controller and how it improve the operation of an electrical transmission line. Mathematical model, performance, operation and application of TCSC controller has been discussed in this paper. Simulation of the MATLAB circuit without and with TCSC controller has been done using MATLAB software.
