“…One of the promising ways of improving power quality in operation of AC VFIMD is addition of an active rectifier (AR) in a frequency converter (FC) [3][4][5][6][7][8]. FC with AR are an effective tool for the power quality improvement and energy saving in mining machines with VFIMD, and enjoy widening application therefore, for instance, in shovels [1,4].…”

The paper presents the results of a study on hybrid filter operation and performance under hybrid power supply. In the study, a hybrid filter structure was developed and proved to perform a set of power quality improving functions. The paper demonstrates that it is necessary for the hybrid filter structure to be variable in order to adapt to changes in power supply. A case is made for using an additional passive filter at the active part output of the hybrid filter under distributed generation. The optimal structure and parameters of such an additional passive filter are identified and proved. Based on the experimental research results, the mathematical and computer simulation models of the proposed hybrid filter for hybrid power supply were developed. The modeling and simulation results showed the efficiency level to be satisfactory and power quality to improve due to applying the proposed hybrid filter. Using the modeling and simulation results, an adaptive algorithm to control the operation factors of the proposed hybrid filter under hybrid power supply was developed, tested, and evaluated. Practical recommendations for industrial application of the proposed hybrid filter are given.

“…The power of electric drive systems used at the mine reaches tens of MW and constitutes the main share of the enterprise's load that determines the nature of the impact of higher harmonics on the power supply system as a whole [9]. One of the effective measures used to reduce higher harmonics generated by an electric drive to normalized values is the installation of filtercompensating devices [10].…”

In the paper, theoretical and experimental studies including measuring of the electricity quality indices at mining enterprises were made. The evaluation of the efficiency of the applied means of highharmonic compensation was fulfilled. The proposals to create the system for continuous monitoring of power quality indices were developed. Electrical devices of surface and underground complexes of mines connected to distribution networks 6 kV and used in mining and processing of diamondiferous ores were considered as the research objects. The results of installation of the monitoring system of electric power quality indices at electric drives and frequency converters of some process units were studied. Technical and economic analysis was carried out, and the guidelines concerning the improvement of energy efficiency of frequency-controlled electric drives were formulated.
