Enhancing performance efficiency of electric consumers within surface infrastructure of coal mines

This study analyzes influence exerted by coordinate adjustment of electromechanical systems (EMS) in the structure of electric consumers within the surface infrastructure of coal mines, namely, mine hoists, on high-order harmonic generation. The authors propose a test procedure and a functional chain of the mine hoist EMS for the analysis of high-order harmonic generation at different-type coordinate adjustment. The article describes the simulation models of EMS of mine hoists with different-type coordinate adjustment. The results of the simulation modeling of the mine hoist EMS with standard setting, open-loop control, as well as with parallel and mixed-type coordinate adjustment are analyzed. The conclusion on the influence exerted by the coordinate adjustment on the high-order harmonic generation by the electric consumers of surface infrastructure of coal mines is drawn.
