commissioning work at the renovated Julfa substation in
Azerbaijan’s Nakhchivan has been completed, the State Energy
Service of Nakhchivan told Trend.
The Julfa substation with a capacity of 132/110/10 kV, built in
2004 in accordance with the electricity needs of that time, has
been completely reconstructed, since the old equipment did not meet
modern requirements and had exhausted its service life.
The installation of transformers purchased for the Julfa
substation within the framework of the “State Program for the
Socio-Economic Development of the Nakhchivan Autonomous Republic
for 2023-2027” has been completed. The final testing and adjustment
works of the relay protection and SCADA systems at the substation
were carried out with the participation of specialists from the
State Energy Service, the Open Joint Stock Company “Azerenergy” and
the Turkish Europower Energy and Automation Technologies San. Tic.
Anonim Şirketi company. The substation was connected to the
automated dispatching system SCADA of JSC Azerenergy.
The substation was equipped with one new 132/110 kV 50 MVA
transformer and two new 110/35/10 kV 16 MVA transformers, bringing
the substation capacity to 82 MVA.
An open switchgear unit (OSU) of 110 kV was built at the
substation, a cable well was constructed, an optical cable was
laid, modern electrical equipment, electronic relay protection and
automation systems that meet international standards were
installed. To meet internal energy needs, solar panels and three
5-kilowatt inverters are installed on the roof of the building. The
necessary working conditions have been created for the duty
personnel, and appropriate service, maintenance and management
premises have been built.
The construction of a 35-kilovolt closed switchgear at the
substation and its connection to the grid will create a 35-kilovolt
ring power supply circuit for the Julfa district, as well as ensure
the stability and reliability of the power supply.
The reconstruction of the substation made it possible to change
the connection schemes of 110 kV power transmission lines. Thus,
the reliability of the 110 kV power supply scheme between the
Bilava HPP and the 110/35/10 kV Cheshmebasar substation was
increased, and the future connection to the 36 MW Ordubad HPP
substation was taken into account.
