AutomatiC Compensation of reaCtive power with a system for monitoring a 6 kV eleCtriCal power grid in a mine

摘要

The paper features a ConCept, exeCution and results of a Central system for automatiC reaCtive power Compensation of a 6 kV eleCtriCal power grid in a mine. The following were used as Controlled Compensators of reaCtive power: synChronous motors of driving systems working in a mine, CapaCitor batteries and filters of higher harmoniCs. Then a CommuniCation system was desCribed. Finally, a system for monitoring the state of the mine grid was presented.
