Abstract

Medium voltage distribution networks of 6–35 kV are used in inplant power supply systems at steel mills. As a mutual influence result of long cable line capacitances and step-down transformer inductances, resonance phenomena can occur in the medium frequency range. If the high-frequency harmonics generated by frequency converters with active rectifiers fall into the resonant range, this can lead to disturbances in the plant internal distribution network. Such phenomena can cause long downtime of technological equipment and product defects. This entails significant economic losses, especially in the production of high value-added products. This paper reflects the experimental research results of voltage quality in 34.5 kV distribution networks at the metallurgical plant "MMK Metalurji". The purpose of the experimental studies was to analyze the current operating modes of the power supply system in order to develop scientifically substantiated technical measures aimed at improving the voltage quality at the point of common connection with internal consumers in the main mode of the power supply system operation. The Fluke 435 power quality analyzer and the Fluke i5s current clamp were used in the experimental studies. Measures for electromagnetic compatibility improvement of frequency converters with active rectifiers of electric drives in hot strip mill 1750 with supply mains are proposed.
