The transit possibility of the south-west part of common elektric power systems of the countries CIS
This paper analyzes the transit possibilities South-West part of the CIS power system. As the South- Western part CIS power system are considered power systems of Moldova and southern Ukraine. The paper shows the results of the limit values of possible transit power flows through the power section of Moldova and Ukraine, working in sync with each other and with CIS power system. Through this section may transit capacity in the power system of Romania, Bulgaria and other countries in the region. It is shown that under the current operating condition of high intersystem connections limit value of the transmitted power by overhead 330 kV and 110 kV overhead line connecting the power system of Moldova and Ukraine, can reach values of the order of 1400-1500 MW, and for 400 kV and 110 kV transmission lines connecting power system of Moldova and Romania, it can be 600-700 MW. Further increase transit capacity of this electrical can be achieved through the construction of new overhead transmission lines, both external and internal, restoration of the transmission line 750 kV South - Ukrainian nuclear power plant - Isakcha, as well as a number of technical measures for the synchronous operation of energy systems of Ukraine, Moldova and the countries CIS and create opportunities to work together with the power system of Romania, Bulgaria and other countries in the region.
