Simulation of single phase Shunt Active Power Filter for domestic non-linear loads

The realization of the standards and guidelines such as IEEE-519-1992/ IEC 61000 has attracted the attention of both utility and consumer to share their responsibilities, to keep the harmonics contamination within acceptable limits and provide quality power to the consumer. Harmonic mitigation can usually be done by the use of conventional active filters. Conventional passive filters, namely LC passive filters, possess the merits such as the simple structure, low cost and can compensate reactive power along with harmonics elimination. But PF based on resonant principle have many disadvantages, such as large size, fixed compensation, tuning problems etc. To overcome aforesaid problems, active filters came into picture to provide appropriate solution best suited to the compensation necessities under dynamic load conditions. This paper presents the study and simulation of Shunt Active Power Filter using hysteresis current controller for different non-linear loads.
