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.
