Modeling and Simulation of Different System Topologies for DSTATCOM

Power Quality enhancement in a distribution network is achieved by shunt compensation device known as Distribution static compensator (DSTATCOM).In this paper, three different system topologies for Distribution Static Compensators (DSTATCOMs) are modeled and tested using Simulink'SimPowerSystem Toolbox for power system quality studies. Simulation tests on a distribution system, equipped with the unbalanced and non-linear load. With the different system topologies of Distribution Static Compensators (DSTATCOMs) it is observed that power factor can be improved in supply system. The DSTATCOM controls are based on Synchronous Reference Frame control. The modeled DSTATCOM topologies can be used to develop and test different, control strategies and methods for the DSTATCOM. These models can also aid instructors in teaching power quality courses.
