Abstract

Taking into consideration the current financial situation of the country and energy in general, and the fact that since 1990 there have been no new facilities, the best way to maintain and ensure the energy security of the country is the restoration of the existing thermal and nuclear power plants in order to extend the service life of equipment for 15 - 20 years, and to increase its efficiency and ecological compatibility. The most significant connection of the low-potential complex with a power unit is carried out through the final parameters of stream (Pk, tk) and the consumption of electricity to drive the pumps of the complex.

The most significant connection of the low-potential complex with a power unit is carried out through the final parameters of stream (Pk, tk) and the consumption of electricity to drive the pumps of the complex, i.e. the low-potential complex affects the efficiency of thermal power plants, affecting their performance
