“Zvenigorod” 110/35/6 kV substation (SS) is waiting for the next phase of reconstruction. S has been in operation since 1969 and it provides electricity to the urban settlement Zvenigorod, the population of which is growing steadily.
Renovation of the feeding center began in 2010. Full completion is scheduled for the end of 2015.
During the first phase, two 20 MVA transformers by two power transformers of 40 MVA each was implemented to remove overload in the grid. Vacuum circuit breakers of 6 kV were installed to replace obsolete bus section breakers.
A new stage stipulates an increase in the total transformer capacity from 80 MVA to 126 MVA. For this purpose, two transformers of 40 MBA will be replaced by two 63 MVA ones. The project provides for installation of new switchgear assembly of 35 kV using vacuum breakers.
The outdoor switchgear of 110 kV will also pass reconstruction. It is planned to install two additional cells for connection of another two 110 kV power lines, which are constructed to improve reliability of the main scheme of substation connection to the grid.
A new building of common substation control panel (CSCP) will be constructed to ensure smooth transmission and distribution of electricity; communication equipment involved in switching will be located there.
According to Victor Ivanov, chief engineer of the Western Electric Grids – the branch of JSC “MOESK”, “Throughout the whole period of its reconstruction, the substation will remain to be in operation. Before dismantlement of equipment, energy specialists will develop a backup power supply scheme and agree it with the Moscow Regional Dispatching Administration in order to prevent decline in quality of life of people.”
Reconstruction of the substation “Zvenigorod” is one of the largest projects of the long-term investment program in the branch. The Western Electric Grids will assign more than RUR 5 bn in 2013 in total for construction and modernization of existing centers, fulfillment of technical re-equipment and reconstruction of existing electric grids.
