ArcelorMittal Kryviy Rih Upgrades Electric Substations
09/15/2011 - PJSC ArcelorMittal Kryviy Rih has implemented new filter-compensating devices at electric substations No. 8 and 18 that will help to ensure more stable operation of electric equipment at all units of the company.
PJSC ArcelorMittal Kryviy Rih has implemented new filter-compensating devices at electric substations No. 8 and 18. The new equipment will enable the facility to improve energy quality by slowing down the frequency of net energy oscillation and increasing the electrical power factor. The upgrade will help to ensure more stable operation of electric equipment at all units of the company.
According to the company, installation of the new filters is an important step forward in the process of improving energy efficiency. The upgrade will lead to a reduction of the company’s total reactive energy consumption, and an expected cost saving for energy consumption of around 360,000 UAH per year.
The company said the new equipment also will positively impact operational safety, as the filters are equipped with microprocessor units for security and control. Because the units are completely automated, company specialists will only need to monitor filter operation, record their energy readings, and maintain the devices regularly. The company has made maintenance of the devices much safer for employees by building special premises for the filters at substation No. 8. Filter-compensating devices were mounted at substation No.17 on open air ground.
According to the company, installation and maintenance of new filters at the substations lasted about nine months. The total cost of project amounted to 18 million UAH.
“New filters enable to improve electric power specification produced by our substations,” said Aleksandr Balahnin, Foreman of Substation Net Shop of PJSC ArcelorMittal Kryviy Rih. “Now we can significantly reduce the number of defects in net impacted negatively energy quality of operation of electric motors and cables in the shops. Now we prepare to measure improvements of energy in our nets. And filter-compensating devices enable to reduce energy consumption payments significantly.
“We expect this cost saving will help to repay installation of filters in 2 or 3 years. The company plans to install such filters at substation No.5 in 2012.”
