Abstract
The research of electrical power quality of electrical complex of oil refinery OOO PO Kirishinefteorgsintez was carried out. The values of distortion coefficient of sinusoidal voltage curve in the network in the spectrum of harmonics 6k± 1 (5, 7, 11, 13, 17), showing that their sources are 6-pulse frequency converters of the regulated drive. The negative impact of the higher current harmonics on the electrical consumers of the oil refinery has been determined. For normalization of electromagnetic situation and reduction of non-sinusoidal voltage are proposed: schematic measures, use of filtering devices, use of special equipment, characterized by a reduced level of generation of higher harmonics in the network.
