Recent Trends in Real and Reactive Power flow Control with SVC and STATCOM Controller for transmission line

ABSTRACT Flexible alternating current transmission systems(FACTS) technologies opens up new opportunities for controlling power and enhancing the usable capacity of present as well as new upgraded lines. FACTS devices use power electronics components to improve system performance. This paper will discuss and demonstrate, how fixed capacitor thyristor controlled reactor (FCTCR) and static synchronous compensator (STATCOM) are applied to control transmission system dynamic performance for system disturbance and effectively regulate system voltage. SVC and Static synchronous compensator (STATCOM) is basically a shunt connected Static VAR generator whose output is adjusted to exchange capacitive or inductive current so as to maintain or control specific power variable; typically the control variable is the SVC bus voltage. One of the major reasons for installing SVC is to improve dynamic voltage control and thus increase system load ability. This paper shows the performance of the system for SVC and STATCOM devices in improving the power flow in transmission line. All the simulations are carried out by using MATLAB/SIMULINK software. The simulation result shows the performance of FACTS devices in transmission line.
