The paper uses the methods of mathematical modeling and instrumental control to justify the introduction of energy-saving measures and technical solutions in the power supply systems of mining enterprises. An assessment of the implementation of energy saving methods in electric drive and power supply systems at mining enterprises demon-strated the possibility of achieving a multiplier economic effect with the right approach to the implementation and subse-quent operation of energy-saving technologies. The energy saving potential was shown in the industry in ge¬neral, and in mining enterprises in particular. For example, in some areas of enterprises, such measures as reactive power compensa-tion, the introduction of automated electric drive systems, the development and pilot operation of power quality control systems with continuous recording of indicators were considered. The mathematical modeling method was implemented using the MatLab software package which has proven itself in engineering calculations around the world. Instrumental control and evaluation of power quality indicators were carried out in accordance with the requirements of GOST RF 32144–2013. As a result of the potential optimization of individual power supply systems, the estimated total economic ef-fect due to energy savings was obtained. The figure approached 28 million rubles per year, which is on average 20% of the cost of electricity consumption of the considered sites of mining enterprises.

“…Its characteristics depend on the methods used to generate control signals for active filters. In this case, it is advisable to use a strategy for generating control signals based on the use of instantaneous values of symmetrical components of voltages and currents of a 3-phase network [11][12][13][14][15][16].…”

The article considers a hybrid power quality conditioner (HQPC) for 3-phase 4-wire systems with a distributed modular structure. Some conditioner modules provide compensation for the component currents and voltages that form the negative and zero sequence systems. The open structure of the HQPC, consisting of independent modules, allows compensating for distortions of currents and voltages of the 3phase network caused by the nonlinear nature and asymmetry of single-phase loads. The compensation characteristics of the proposed conditioner were researched using a model developed in the MatLab environment. The simulation showed that the proposed conditioner can ensure normalization of power quality in 3-phase 4-wire system at various modes of network operation.
