The plant will be connected to the existing 220 kV and 500 kV transmission
systems in the North Caucasus Region. New transmission lines will be
constructed for this purpose and the existing transmission lines running through
the site will be rerouted.
This design was accomplished by carrying out a detailed study of the region's
existing transmission system to determine the upgrades that will be required to
bring 900 MW of new capacity on line. These studies included detailed load flow
and fault analysis, dynamic studies and system stability studies. These studies
assumed that the existing ties between the North Caucasus region and the
Ukraine will remain available and that the first stage of the interregna1 tie between
the Center region of the Russian Integrated System and the North Caucasus
comprising three 500 kV lines from Balakovskaya Nuclear Plant to Rostovskaya
Nuclear Plant will also become available.
The load flow studies indicated that to deliver power to the regional consumers at
220 kV, three new substations will need to be constructed in Kurgannaya,
Cheremushki, and Zilposelok. These additions and changes include:
