Abstract
This paper mentions parallel resonance impact on power factor improvement in power system with harmonic distortion and correction. This paper illustrates effect of parallel resonance phenomenon to harmonic voltage and harmonic current amplification in power system by illustrated a case study for power factor improvement in power system with harmonic distortion and a case study for correction of harmonic voltage and harmonic current amplification when corrected power factor of power system with harmonic distortion. A power system model is established with MATLAB/Simulink. A non-liner load, which is a harmonic current source, is a direct current variable speed drive (DC drive). This paper mentions a direct current variable speed drive (DC drive) because it is the most type of motor speed control and it has a low power factor, resulting in a need for power factor correction. The mitigation of harmonic voltage and harmonic current amplification on capacitors when parallel resonance generated in power system is connection of series reactors (the detuned filter) to capacitors in a power factor correction device because this solution is cheaper and easier than other solutions.
