Rosseti Centre Belgorodenergo (a branch of IDGC of Centre - Belgorodenergo) completed the modernization and technical re-equipment of the 110 kV “Promyshlennaya” substation in Stary Oskol.
As part of the reconstruction, the power engineers replaced relay protection and emergency automation systems, upgraded remote control and electricity metering systems, installed vacuum and gas-insulated switches instead of obsolete oil switches and short-circuiters.
A high level of observability and rapid response to emergency processes is implemented at the facility. All data on operating parameters of equipment is supplied to the operational information complex of the City Dispatch Centre of the Stary Oskol Distribution Zone. At the same time, the dispatcher can not only monitor technological processes, but also provide remote control of switching devices and relay protection and automation devices, and make necessary switching at the substation.
The 110 kV “Promyshlennaya” substation with an installed capacity of 50 MVA was commissioned in 1983. The facility provides power to a number of large consumers, including the confectionery “Slavyanka”, the dairy plant “Avida”, a pumping station of the Oskol water and wastewater treatment plant and many others. The reconstruction of the feeding centre will significantly increase the reliability of electricity supply to residents and enterprises of the Stary Oskol city district.
