Design of Shunt Active Power Filter Using Reference Frame Theory For Power Quality Improvement

This paper deals with design of shunt active power filter using reference frame theory. To reduce total harmonic distortion (THD%) in source current below the IEEE standard-519 of 5% permissible limits, paper gives simulation on shunt active power filter using reference frame theory. The result shows that the distortion in source current and THD is reduced within the permissible limit.
