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%
