Power Quality Analysis in a Distributed Power System Using D-SATACOM and DVR

ABSTRACT: This paper describe the more reliable power electronic devices for a stability analysis of power by correcting the supply voltage sag, swell and interruption in a distributed power system. The use of sensitive electronic equipment has increased. N ow days which have lead to power quality problems. To solve these power quality problems various custom power devices are used. At present, a wide range of very flexible controllers, which capitalize on newly available power electronics components, are emerging for custom power applications. Among these, the distribution static compensator (D-STATCOM) and the dynamic voltage restorer (DVR) both of them based on the VSC principle. DVR & D-STATCOM both are most effective devices,. A DVR injects a voltage in series with the system voltage and a D-STATCOM injects a current into the system to correct the voltage sag, swell and interruption. Simulation results using Matlab/Simulink are presented to verify the effectiveness of these devices. I
