Branch of OAO UES FGC completed the construction and installation of the main power equipment on the reconstructed 220 kV substation gas in the Astrakhan region

The branch of JSC "FGC UES" — Trunk Power Grids (IEC) Center — has completed construction and installation of the main power equipment on the reconstructed 220 kV substation "gas" in the Astrakhan region. Reconstruction of power is carried out in the framework of the investment program of OAO "UES FGC". As a result of the modernization of the substation will be significantly improved the reliability of power supply of the city of Astrakhan with a population of about 500,000 people.

To date, on-site reconstruction of the buildings of Substation Control (GTC), the closed distribution system (ISG) 10 kV, checkpoint, pump, camera switching valves, completed the construction of oil receivers. Mounted primary equipment of outdoor switchgear 110, 220 kV substation control house, indoor switchgear 10 kV. Installed at regular places and mounted two auto-transformer with a capacity of 125 MVA, two reactors with a capacity of 25 MVA. Installed lighting and radio towers. Laid-site roads and cable channels.

At the moment, scientists began laying power cables and installation of secondary equipment. In the course of the panel will be mounted digital relay protection and automation, automated process control and metering of electricity. Complete installation of the secondary equipment is scheduled for the second quarter of 2011.

Complex reconstruction of the 220 kV "gas" began in 2009. After replant existing power lines to the new equipment will be dismantled old. As a result of the reconstruction of the substation will be highly reliable, compact, and low-maintenance. The installed capacity of the substation will increase by 62 MVA and will be 250 MVA. The planned date for completion of reconstruction — December 2011.

220 kV substation "gas" transformer capacity of 188 MVA was built in 1985 to supply the Astrakhan gas processing plant. Today substation is the main supply center of Astrakhan. From its stable operation depends on the reliability of electricity not only a gas processing plant, but also the gas compressor stations, LLC "Gazprom mining Astrakhan."
