Abstract: The growth of interconnected power system continuous process as the demand of power is increasing day by day. As per power demand is increasing, power generation is also increase, and hence need of reactive power compensation; oscillation damping improves more, and improved the voltage control. This research paper is present behavior of TCSC on the transmission line. Here for different value of firing angle the influential characteristic of TCSC is simulated.
