Simulation modeling of the power supply system of the coal mine excavation area with facts devices

The introduction of technologies for active-adaptive control of the operating modes of the power supply systems of coal mines can contribute to an increase in the energy efficiency of coal mining. High-response FACTS devices of the second generation can be used for dynamic reactive power compensation, voltage regulation and limitation of current and voltage harmonic components in conditions of sharply variable electrical loads of mining machines at a breakage face. Evaluation of the effectiveness of the implementation of FACTS devices in the power supply systems of coal mines can be performed using simulation methods.This article discusses the main approaches to the development of a simulation model of a power supply system of a coal mine, mining equipment and FACTS devices. The main results of modeling the joint operation of mining machines are shown. Conclusions about the effectiveness of the use of FACTS devices in the extraction area of a coal mine are made
