Reduction In Total Harmonic Distortion Using Active Power Filters

Abstract-Power Quality issues are becoming the most important concern of today’s power system engineers. Harmonics play considerable role in deteriorating power quality, called harmonic distortion. Harmonic distortion in electric distribution system is all the time more growing due to the extensive use of nonlinear loads. Active power filters are quite new and rather expensive but they do have various important advantages that should be watched carefully which are inherently current limiting, have no resonance problems, are adaptable, can be configured to either correct the full range of harmonics or to target particular harmonics and being able to balance for harmonics without fundamental frequency reactive power concerns. For the accurate function of the filter, it is essential to determine the magnitude of the currents, which have to be added to load current so as to get rid of high harmonics in the supply current. This manuscript introduces the performance of Active Power Filters which are helpful in removing the total harmonic distortion and also helps in enhancing the power quality of the power system network
