REVIEW OF SHUNT ACTIVE POWER FILTERS CONTROL STRATEGIES FOR ELIMINATION OF HARMONICS

Abstract

Energy electronic loads are being linked to the allotted energy flora thru strength digital converters and those electricity digital converters and hundreds are the source of harmonics and reactive energy which affects the performance of the strength system network. Switching compensators called lively filters or active strength line conditioners brings an effective alternative to the traditional passive LC filters as they can make amends for numerous harmonic orders, and are unaffected by means of primary changes in community characteristics, keeping off the threat of resonance between the clear out and network impedance and are compact and strong in comparison with traditional passive compensators. The overall performance of the power system relies upon on the excellent of strength on which system are working. The power quality depends on various factors. These factors include voltage & frequency variations, faults and line outages in the system. The reduction in power quality reduces the life and efficiency of the equipment of the system.
