Abstract

The excessive use of power electronics elements in power distribution system creates the power quality problems because of its own non-linear (V-I) characteristics and switching instants. That quality of power can be improved by usage of the compensators and active power filters. This paper gives the Simulink model of shunt active power filter for improvement of quality of power. Harmonic currents produced by non linear loads are compensated by shunt active filter and maintain the source current sinusoidal. In this proposed methodology shunt active power filter is acts as a current source and eliminates the harmonics by injecting equal but opposite current harmonics components at the Point of Common Coupling (PCC). The operation of shunt active power filter explained using instantaneous reactive power (IRP) theory with Hysteresis Band current controller (HBCC) and PI controller. The simulation results of the shunt active power filter using instantaneous reactive power (IRP) theory is simulated by MATLAB/SIMULATION tool box.

Keywords: Shunt Active Filter (SAF), Hysteresis Band current controller (HBCC), PI controller, Instantaneous Reactive Power (IRP) theory.
