Abstract: The purpose of this work is to present an approach to determining the parameters of mine-type capacitor units in the conditions of their use in the underground part of the power supply systems of mining sections of coal mines based on the use of simulation and optimization methods. The article gives a brief description of the optimization methods used for reactive power compensation and substantiates the use of a surrogate optimization algorithm. Further, the authors present a description of the objective function used, which includes the value of the net present value, and make a mathematical description of the optimization conditions. The work uses a simulation model of the power supply system for the excavation area of a coal mine and electric drives for mining equipment, implemented in the Matlab - Simulink environment, and which allows simulating the operation of the power supply system for the excavation area in dynamic modes, taking into account mining and geological conditions and technological parameters of mining machines. The final part of the article presents the results of optimizing the parameters of capacitor units in the implementation of reactive power compensation at the stage of operation and design of the power supply system. Conclusions are drawn about the high economic efficiency of reactive power compensation, as well as significantly better performance in the implementation of measures at the design stage of the power supply system.
