Power Quality Improvement by Reduction of Harmonic using Shunt Active Power Filter

This paper focuses on the harmonic reduction by using shunt active power filter. The reduction in harmonics reflects as improvement in power quality. This paper includes the operation of shunt active power filter. It also includes the Simulink model and their results. It also describes the PI controller used in Simulink model. The total harmonic distortion is compared with filter and without filter. The permissible limit of THD is also followed as per IEEE.
