POWER QUALITY IMPROVEMENT IN DISTRIBUTION SYSTEM USING D-STATCOM

In this paper we present DSTATCOM (static synchronous compensator) is a power electronics device using force commutated device like IGBT to control the reactive power. In powernetwork voltage is stabilise whilesynchronizing withdemand.The D-STATCOM used to mitigate the power quality issues like voltage sag, voltage swell, harmonics and compensation the reactive power. InVSC voltage source converter can act as either a source or sink of reactive power. TheD-STATCOM has many features such as low power losses, lessharmonics production, high regulatory capability, lowcost and compact size.In matlab we can use distribution static compensator model.
