Comparison of Passive LC and Passive Single Tuned Filters in Reducing Current Harmonics

Abstract

Harmonics generated by non-linear loads will cause the current to be in the form of short pulses. From the measurement data conducted, there is a harmonic on Individual Harmonic Distortion (IHDi) fifth order on current transformer that is not compliant with IEEE 519 -1992 standard. In this study aims to compare the use of passive LC filter with Passive Single-Tuned Filter in reducing harmonics current is simulated using computer program. The simulation results show the Current Individual Harmonic Distortion (IHDi) fifth order in the current transformer is reduced according to IEEE standard 519 -1992 where IHDi fifth order is reduced to 0.04% using Passive LC Filter and 1.14% using Passive Single-Tuned Filter and THDi decreased to 0.28% using Passive LC Filter and 2.54% using Passive Single-Tuned Filter.

Analysis and Mitigation of Harmonics Distortion with Optimization Capacitor Banks and Single-Tuned Passive Filters

“…Automatic sizing of harmonic filters is provided by the harmonic package, which requires only harmonic orders and harmonic currents. A desired model or harmonic analysis of the power system can be used to obtain the desired harmonic order current magnitudes [17], [18]. However, automatic dimensioning only compensates for reactive power through filters.…”
