Improving Power Line Utilization And Performance With Facts Devices In Disturbed Power Systems<br>
<br>

<strong>Abstract</strong><br>
This Paper describes the theory and simulation by mat lab of flexible Alternative Current Transmission Systems 
(FACTS) devices used in the disturbed power systems. One of these devices, Unified Power Flow Controller (UPFC) will be 
chosen for a specific application,  detailed in this  Project.  Simulation investigate the effect of UPFC on the voltage of the 
related bus, it also considers the effect on the amount of active and reactive power flowing through the transmission system. 
Finally  simulation  results  have  been  presented  to  indicate  the  improvement  in  the  performance  of  the  UPFC  to  control 
voltage in disturbed power systems.
