PENGARUH FILTER AKTIF DENGAN PENGATURAN DAYA REAKTIF TERHADAP EFISIENSI TRAFO BERBASIS SIMULINK

Abstract

Harmonic distortion usually occurs due to the operation of excessive non-linear
electrical loads, this distortion can be reduced by utilizing an active harmonic filter which can
usually be adjusted for reactive power on the filter. In this study, an analysis of reactive power
settings on the active filter was carried out to determine the efficiency value obtained by
following the IEEE 519 - 2014 THDi standard value of 8% for each phase. The results of the
analysis of the smallest reactive power setting but exceeding the transformer efficiency value
when the existing condition meets the IEEE 519 - 2014 standard is 40 % with the THDi value for
the R phase = 7, 54%, S = 7,74%, and T = 7, 37% obtained an efficiency value of 96, 31%.
