A Review of Various Topologies and Control Schemes of DSTATCOM Implemented on Distribution Systems

Nowadays the demand for receiving the high quality electrical energy is being increasing as consumer wants not only reliable but also quality power .The usage of automated equipment are increasing and far more susceptible to disturbances compare to the prior generation equipment and information systems. With the deregulation of the electric power energy market, the awareness concerning the quality of power has been increased day by day among diverse categories of customers. Power quality has become an important topic to electricity consumers at all levels of usage. Power quality can be improved in distributed system by using shunt compensation device known as Distribution Static Compensator (DSTATCOM). This paper covers the different topologies of Distribution Static Compensators (DSTATCOMs) and the various control methodologies, and its selection for specific applications.
