TCSC employs fast switching ability of power electronic devices and is able to control power flow on transmission lines during various alarming stages. The aim of this work is to integrate TCSC into 500 KV Hubco-Jamshoro transmission line to investigate the operational benefits. A simulation model is developed under MATLAB/Simulink and many simulation studies are performed to verify the feasibility of the proposed model for transmission line. The core essence of this work is to improve the power transmission capabilities of 500kV transmission line by employing TCSC switching schemes, which helps to compensate the power flows when installed in transmission line and thereby increases the transmission line loadability.
