| Summary: | Power quality standards (IEEE-519) require to limit the total harmonic distortion within satisfactory
range caused by power electronic based devices. Our work deals with the design of hybrid active filter to
reduce current perturbations produced by power electronics based devices. The Instantaneous Active and
Reactive Power Method (pq) is used to perform the identification of disturbing currents. The pq algorithm
creates a reference current, whereas, this reference current is tracked by the current of the voltage
source converter. The currents of the voltage source converter are controlled by hysteresis controller.
Simulation results showed that the hybrid active filter can compensate the harmonic currents effectively
and improve power quality. |
