摘要：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. Now 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.
