Abstract
Due to the rapid technological progress,
theconsumption of electrical energy increases
continuously.In this paper the frequently occurring
power quality problemvoltage variation has been
discussed. The voltage sag/dip is the most frequently
occurring problem. There are many methods to
overcome this problem. Among them the use of FACT
devices is an efficient one. This paper presents an
overview of the FACT devices like- DVR and DSTATCOM
in mitigating voltage sag. Each one of the
above device has been studied and analyzed along
with the control strategies to control these devices.
The proposed control strategies have been simulated
in MATLAB Simulink platform and the results are
presented. A comparative study based on the
performance of these devices in mitigating voltage
sag has been presented.
