Summary

This paper addresses the analysis, mathematical modelling and parameter justification of an active power harmonic filter designed to optimise the operation of industrial electromechanical systems equipped with high-power semiconductor converters. The relevance of the study stems from the growing proportion of non-linear loads in industrial power networks, which causes voltage and current waveform distortion, additional active-power losses, transformer overheating, and premature degradation of motor insulation. Based on an analysis of non- sinusoidal operating modes, a mathematical model of a three-phase parallel-type active power filter built around a voltage-source inverter with IGBT transistors and pulse-width modulation is developed. A real-time algorithm for extracting harmonic current components, based on instantaneous power (p-q) theory, is proposed and provides high dynamic compensation accuracy. Simulation and experimental results are presented, confirming a reduction in the total harmonic distortion factor of the current from 24.6 % to 3.8 %. The technical and economic prospects of implementing active filters at industrial facilities to improve supply reliability and electromagnetic compatibility are outlined.
