Study of Two Machine Power System with Static Synchronous Series Compensator

Modern power system carries very high demand. Thus they cause the stability problem. This paper studies the problem of controlling the power flow through transmission line using a FACT controller named Static Synchronous Series Compensator. In this paper the controller investigate the effect for controlling the active and reactive power as well as damping power system oscillation. Under heavy loaded condition there may be insufficient reactive power causing the voltage to drop. This voltage may lead to drop in voltage at various buses. Flexible AC Transmission System (FACTS) controller have been mainly used for various power system stability .The SSSC equipped with source of energy in dc link can supply or absorb the active power to or from the line along with the reactive power flow control .The SSSC is represented by a variable voltage injection with associated transformer leakage reactance and voltage source.
