Mining enterprise

Company profile

One of the largest producers of metallurgical-grade coal, the world’s leader in supplies of high quality Ultra High Grade (UHG) anthracite.
In 2019, the production volumes amounted to 23.7 million tons of coal and anthracite.

Before implementation:

  • An increase in production volumes led to an increase in enterprise production capacity .
  • High losses in power lines (about 2 MW).
  • Voltage surges and dips that reached 1kV affecting the entire power system.

Project results:

  • Reactive energy was compensated by combining the operation of capacitive and inductive excavators, and the annual data statistics helped to select reactive power compensators
  • The problem of voltage surges and dips, which reached 1kV, was eliminated
  • The analysis of power supply system parameters showed the true picture for different types of consumers
  • The difference between manual input and system reactive energy data totaled to 145 hours of excavator downtime
  • Reduction of losses in power lines from 2 MW to 500–600 kW
  • Calculations based on water meter readings led to a decrease in costs for discharges into rivers by more than 60%
