A simplified example to upgrading of a hydropower plant through re-equipment and extension with a pump-hydro-storage-unite [articol]

Abstract

It is known that hydropower is one of the most reliable and proven sources of generating electricity, with three important attributes: it is renewable, available on demand, and it can be used to store power. But the normal life expectancy of a hydroelectric power plant is only 30 to 35 years and consequently renovation and usually upgrading is required thereafter at the end of this period. In the present paper a briefly calculation example to efficiency analysis of upgrade and modernization of a hydropower plant as well his extension with a pump-hydro-energy-storage- unite. This can be an aid as orientation basis for the elaboration of some preliminary studies to updating of existing waterpower plant.
