In the present time of industrial and modern technologies, the demand of power is increasing day by day. In the recent past, the major problem power system instabilities with and transmission facilities with increase in the load demand of electrical power is due to rapid industrial development. So there is an immediate requirement to increase the quantity, quality and reliability of highly complex power systems. Power instability is the major problem that the industrial and domestic sector is facing nowadays. Construction of new power grids and transmission lines is not the best option due to some constraints i.e. permits granting, land acquirement and cost considerations. Here we need some improvements such as of reactive power compensation and improved the voltage control. In these aspects a TCSC is very useful in improvement of quality of supply and to reduce the power loss. The paper discusses the conceptual study of a TCSC device in the transmission line and the various characteristics and impedance curve characteristics of TCSC device using a Simulink model of TCSC in the matlab.

Keywords: TCSC, Power Quality, Voltage sag, Voltage swell, Simulink, impedance curve characteristics.
