The assessment of the series active filter efficiency in power supply systems of oil production enterprises

Abstract

This paper deals with the problem of the efficient application of the series active filter in conditions of power supply systems of oil production enterprises with non-linear load and voltage dips. The mathematical model of the power supply system of oil production enterprise with the connected series active filter is developed. The control system for the series active filter with usage of the phase transformations, symmetrical components and frequency-controlled pulse-width modulation of IGBT control pulses is developed and proved. Based on the modelling results, the analysis of the efficiency of power quality indicators' correction by means of the series active filter is carried out. The dependence of the voltage total harmonic distortion factor from the rated power of the output transformer of the series active filter is obtained.
