The Results of the Implementation of the System for Monitoring the Quality of Electricity in Mining Enterprises

The work carried out theoretical and experimental studies on the measurement of electric power quality indicators at mining enterprises, assessed the effectiveness of the applied compensation instruments for higher harmonics, and developed proposals for creating a system for continuous monitoring of electric power quality indicators. As objects of study, electrical installations of surface and underground complexes of mines connected to 6 kV distribution networks and used in the extraction and processing of diamondiferous ores were considered. The results of the introduction of a system for monitoring the quality indicators of electric power on electric drives and frequency converters of a number of technological units are considered, a feasibility study is made and recommendations are made to improve the energy efficiency of using a frequency-controlled electric drive.
