The power quality and electromagnetic compatibility have been studied and analyzed in power supply systems of oil-producing enterprises. Measurements were carried out at the 35,6 and 0,4 kV buses at the switching stations of oil-production plants by means of the «Resurs UF2M» measuring device. Deviations of power quality indexes from GOST 13109-97 standards have been revealed through these measurements. Recommendations have been developed, which allow enhancing power quality in power supply systems of oil-producing companies by means of on-load regulation of voltage adapter settings of power transformer and installing active and passive filters to equalize upper and lower harmonics. A structure of complex automated system to control power quality and power consumption is proposed for power supply systems of oil-production companies.
