Day by day electrical power consumption has been increasing very rapidly. It must be necessary to supply to all the consumers with quality and reliability. So the exact prediction of load is not possible but only estimated that the generation must be equal to load all the times. Due to variation in load low frequency oscillation, electromechanically oscillations are unavoidable characteristics of power system. FACTS devices can be use to damp these low frequency oscillations. In this paper, result obtained for the dynamic control of the power transmission, damping oscillations with UPFC based on theory & computer simulation through PSAT software. The objective of this paper is to find location of UPFC in a Multimachine power system tested on IEEE-14 bus system, relation between system parameters and effect of oscillation.
