Abstract

In this paper, distribution static compensator is used to compensate the source currents which are affected by the harmonics due to unbalanced and non-linear loads. Here a PV based inverter is used as a shunt active power filter to mitigate the current harmonics. The theory of unit vector control is used to generate the three phase reference currents. Hysteresis current controller (HCC) is used to generate the switching pulses for the gate drives of the grid interfacing inverter. The inverter act as a shunt active power filters to inject the compensated current to the system. The total harmonic distortion (THDs) of the source currents are reduced by using D-STATCOM. The THDs of the distribution system with and without are compared. Further the paper discuss about Fuzzy logic controller and impact of controller on power quality. By replacing PI with Fuzzy we can compare the THD of source current and observed that fuzzy is having better performance than PI. The whole work is been done in MATLAB/SIMULINK.
