Abstract
This paper investigates the usage of passive
harmonic filters to mitigate harmonic distortions when two
resonant points are present in a system caused by shunt
capacitors used for power factor correction and bus voltage
regulation. Six scenarios were investigated using DIgSILENT 14
Power Factory software. The investigations are with and without
power factor correction and capacitors used to increase bus
voltage. Passive harmonic filters are designed to reduce
harmonic distortions at the point of common coupling (PCC) to
fall within the IEEE 519 harmonic voltage and current limits
caused by parallel resonance. The results of the case studies are
analysed to evaluate the effectiveness of the filter design
