Abstract: In the present day scenario, transmission systems are becoming more insecure with unscheduled power flows. The transmission and distribution losses are increasing day by day because of high demand. However, many high voltage transmission systems are operating below their thermal ratings due to constraints, such as voltage and stability limits. This leads to reduction of life of transmission lines and is less economical. The power flow through the transmission network is mainly limited due to line impedance and load angle of the generator. To control the real power flow through any transmission line it is needed to control the impedance of the line or load angle. This control can be achieved by Flexible Alternating Current Transmission System (FACTS) device. In this paper, Thyristor Controlled Series Capacitor is used to compensate the line reactance of transmission line and look up table based TCSC controller is proposed for power flow control. The design and hardware implementation of TCSC control is discussed in this paper. The system stability is analyzed with and without TCSC Controller. It can be achieved by introducing TCSC through a transmission line. The effective impedance of the transmission line is changed by giving series compensation to the transmission line, thus compensating line reactance. This system is tested in laboratory set up for open loop and closed loop control under different operating conditions.
