Paper Title
Comparison Of SVPWM And FFM Tchniques In DVR To Mitigate Volage Sag And Swell
Abstract
In this paper, the operation of DVR is
presented and the control techniques used for voltage
source inverter are Fundamental Frequency Method
and Space vector PWM. Space vector PWM techniques
can utilize the better dc voltage and generates the fewer
harmonic in inverter output voltage than Fundamental
Frequency Method. Phase jump compensation is
achieved by using Phase Locked Loop. This work
describes the DVR based on Fundamental Frequency
Method and Space Vector PWM incorporating the PLL
provides voltage support to sensitive loads and is
simulated by using MATLAB/SIMULINK. The control
approach presented is able to compensate for any type
of voltage sags and swells. THD comparison between
FFM and SVPWM has presented. This work also
intended to assimilate the amount of DC energy storage
depends on the installed load in case of SVPWM.
