Abstract :
This paper presents analysis of different inverter topologies for Low voltage distribution system by using DSTATCOM. The reference currents are generated by using instantaneous symmetrical component theory to control the switching devices using hysteresis current control pulse width modulation. The loads are unbalanced and nonlinear & may draw harmonic currents. The purpose of shunt compensator is to balance the load, as well as make the supply side currents balanced and sinusoidal with unity power factor. In this paper, the compensator is realized using conventional inverter and the effects of different inverter based DSTATCOM topologies for the low voltage distribution system are analyzed. Comparative analysis of inverters on the basis of performance is discussed using MATLAB SIMULINK.
