Power Quality Improvement Using Shunt Active Power Filter

Shunt Active Power Filter are known to compensate the reactive and harmonic currents drawn by the Non-linear load so as to make supply current sinusoidal and have been explored for executing different power conditioning functions simultaneously, along with harmonic elimination. Many different methods can be used to control active power filters, whereby the reference current method forms a very crucial role in determining the active filter performance. The reference current can be calculated by pq transformation. In this paper, used hysteresis current controller for removing of current harmonics is presented. The system was tested and modelled using MATLAB/Simulink.0
