Active power filter simulation for nonlinear Load Harmonics Effects Reduction

Nowadays, the increased severity of power quality problems and other problems associated with the passive filters such as large size and weight, higher cost, fixed compensation, and resonance problems with loads and networks have required a focus on a power electronic solution, that is, active filters. At this article nonlinear Load Harmonics Effects Reduction with active power filter is studied. First a shunt active power filter is simulated on Instantaneous Reactive Power Algorithm and synchronous reference by simulink/matlab. Then its performance is shown with a model that contains a nonlinear load and an ideal power supply.
