Kametstal modernizes substation to improve safety and reliability

The Kametstal plant of the Metinvest mining and metallurgical group (Kamensk, Dnipropetrovsk region) has begun the first stage of a large-scale overhaul of one of its important substations, which supplies electricity to technological processes.

According to the company, the overhaul will also include the modernization of key equipment, which will improve the reliability of power supply and occupational safety.

The main tasks of the overhaul include replacing obsolete equipment that is no longer used in external power grids with modern switching equipment. In particular, disconnectors will be replaced with new 150 kV gas-insulated circuit breakers. Electromagnetic relays will also be replaced with microprocessor-based protection and automation relay units, which provide more sensitive protection with automatic rapid response of equipment to emergency situations.

It is specified that the new equipment will enable the protection of 150 kV electrical circuits directly at the Kametstali substation, whereas previously this was carried out at the remote DTEK substation. This will enable power engineers to localize the emergency area and optimize the process of eliminating the emergency situation.

The report notes that this is one of the most important overhauls of key equipment in the workshop this year, replacing outdated electrical equipment with modern automated equipment. In particular, this is a new level and a modern approach to the process of operational switching, which will now be performed remotely – automatically, using a control key, without the physical presence of employees at the switching device.

“This is a significant step towards improving the safety of our personnel. As a result, we expect to have a modern, reliable power supply system for an important part of the enterprise, as well as improved conditions and increased safety for the personnel of the Central Power Plant,” explained Mikhail Revin, assistant head of the network and substation engineering department, whose words are quoted in the report.

Currently, the old equipment has been completely dismantled at the repair site, and excavation work is underway to pour the foundations for the new equipment. After that, repair specialists will begin its installation.

Kametstal is part of the Metinvest Group.

INTERNATIONAL ATOMIC ENERGY AGENCY INFORMS ON RESUMPTION OF POWER SUPPLY TO CHORNOBYL

Power supply has been restored to the Chornobyl Nuclear Power Plant (NPP) site after repeated damage from hostilities, the International Atomic Energy Agency (IAEA) said.
“Ukraine has informed the IAEA that external power had again today been restored to the Chornobyl Nuclear Power Plant after line had been again damaged by the occupying forces,” the IAEA said in a tweet on the night of Monday to Tuesday.
Other details are not reported.
The IAEA website notes that the “regulatory authority” informed the agency about the resumption of power supply to the Chornobyl nuclear power plant on the afternoon of March 14.
“The regulatory authority told the IAEA that at 13:10 CET external power had again been restored and that staff at the Chornobyl NPP had restarted operations to reconnect the NPP to the grid,” the agency said.
The city council of Slavutych, a satellite city of the Chornobyl nuclear power plant, on its Facebook late on Monday evening announced that the city’s power supply had been resumed and the connection of residential buildings would be carried out gradually.
As reported with reference to NPC Ukrenergo, on March 14, Russian invaders again damaged the high-voltage line supplying power to the Chornobyl nuclear power plant and Slavutych, after the company had repaired it.
The NPP site and Slavutych were de-energized on March 9 due to shelling of energy infrastructure by Russian troops.
