Voltage Stability of 11 kV Feeder by using Thyristor Control Series Compensator TCSC ABSTRACT In the industry real and the reactive powers are governed by the voltage magnitude and the difference of angle at the ends of transmission lines Power transfer in the industry is constrained by the voltage stability and the power stability To stabilize the voltage for the requirement of industry it has always been a challenge demand to increase the power transmission capacity There has been always an issue of voltage stabilization in the power system industry This is mainly due to the high variation of the load Conventionally the voltage stabilization of the industry can be controlled by using the capacitor bank The capacitor bank helps in improving the power factor and voltage will become stable The main disadvantage of this method is that the capacitor is the fixed solution that is calculated and installed for the fixed or full load The issue of the voltage stabilization can also resolved by using the FACTS Flexible AC Transmission System devices Flexible AC Transmission System devices are the solid state devices that are used for the transmission of the AC power
