Article Preview

Abstract:

This paper presents the resonance impact on power factor correction system (PFC system) in power system with harmonic distortion. The main purpose is to show harmonic current amplification that generated by the parallel resonance phenomenon in power system and problem solution. The power system model for analysis consist of the harmonic current source and PFC system. These devices are established by MATHLAB/Simulink. In simulation, the variable speed drive, which is DC drive, instead to the harmonic current source in power system that use capacitor to improve power factor of system. The problem solution, the series reactor, which is detune filter, is used to correct parallel resonance problem, by connecting capacitor with the series reactor, which is detune filter. The result of simulation, detune filter is able to avoid the parallel resonance phenomenon and partially reduce harmonic current that flowing to capacitor, however the series reactor, which is detune filter, is unable to reduce harmonic current of the harmonic current source.
