An increase of hydro-aggregate's installed power and efficiency factor before the revitalization phase

Abstract

The revitalization of hydro-aggregates should be performed before the life-time expiry of most their parts. But, as in our practice aggregates have been under exploitation much longer then theoretical life-time advices (40, even 50 years), there is a need to estimate the equipment's condition through more sophisticated monitoring, providing the maximum level of safety and availability with minimum investment expenses, before the revitalization finally takes place. That estimation is based on appropriating calculations and measurements needed to take the competent decision. Results of that analysis can be also useful for estimation of the aggregate's power and parameters after the revitalization. In this paper the results of appropriate calculations and measurements for the Hydropower station HE Zvornik are given. .

“…Representative data related to technical and economical performances of Plants Djerdap 1, 2 and 3, were selected from the projects (Petrović et al, 2006). Data related to environmental and social impacts of Djerdap 1, 2 and 3, as well as the contribution to the stability of the Electro Energy System (EES) and the involvement of other RES and impact on local community, were the result of different studies (Karakosta et al, 2011b), named in Section 2.3.…”
