Abstract

The influence of converter load on distortion of current and voltage curves is evaluated. The indicators of electric power quality, on which the higher harmonics of converters have the greatest influence, including current curves for 6- and 12-pulse converters, are considered. The results of their Fourier series decomposition are obtained. The harmonic spectrum of these curves is analyzed. Relations reflecting the dependence of the order of harmonics on the converter pulses and allowing the selection of appropriate filters to reduce the negative influence of the converter harmonics on the operation modes of electric networks are given.
