Power Quality Improvement in Distribution System by using DSTATCOM

Solid state power converters are widely used in applications such as Adjustable speed drives (ASD), Static power supplies. Hence it affects the power quality (i.e.) related to non-standard voltage, current and frequency at the load side. In this paper an attempts has been to analyses the role of D-Statcom (Distribution static compensator) and located at load side in the distribution system, which can to eliminating or overcome the problems of source side like voltage sag and interruption etc... In order to maintain the power system quality the D-Statcom will absorb and provide reactive power to mitigate voltage sag, swell, interruption and improve power factor in various conditions. Utility distribution network, sensitive industrial load and critical commercial operation suffer from various type of outage and service interruption, which can cost significant financial losses. Here in this paper the work has been carried out by various techniques with D-Statcom to minimize the problem associated in distribution system such as voltage sag, swell, interruption and low power factor in power system with different condition. D-Statcom used to supply the reactive power and absorb the real power to maintain power quality as well.
