Modeling of Shunt Active Filter Using P-Q Theory

Kirti Vibhute

Abstract: APF's are known to cancels the reactive and harmonic currents drawn by the load so as to make supply current sinusoidal and have been explored for executing different power conditioning functions simultaneously, along with harmonic elimination due to increase in Non-linear & unbalanced loads at the point of common coupling. The paper presents a study of different control strategies for APF's with an emphasis on instantaneous real power theory based Shunt APF, which is predominantly used in present scenario. The filter topologies are investigated through Matlab?/ Simulink? and the design issues of APF for Non-linear load conditions are also discussed.
