| dc.description.abstract | Analize hidrauličnih prelaznih radnih režima su neophodne u fazi projektovanja novih i revitalizacije postojećih hidroelektrana. U ovom radu su razmatrani prelazni procesi pri specifičnim ekstremnim radnim režimima za derivacionu hidroelektranu u kojoj su ugrađeni vodostan i sinhroni regulator pritiska na spiralnom kućištu turbine. Posebni osvrti su na analizama prelaznih režima pri oscilacijama vodenih masa i hidrauličkom udaru. Razmatrani su razni eksploatacioni režimi i različiti zakoni rada sihronih regulatora pritiska. Rezultati su dobijeni pomoću originalnog softvera razvijenog za potrebe ovih analiza. Urađena je kalibracija modela, a rezultati su upoređeni sa analizama prelaznih režima iz faze projektovanja postojeće hidroelektrane. | sr |
| dc.description.abstract | Hydraulic transients analyses are necessary during the design stage of both new and refurbished hydropower plants (HPPs). In this paper, transients of specified most extreme operational regimes are investigated for a long derivation system, provided with a surge tank as well as pressure relief valves (PRVs) at the turbines spiral casing. The transients analyses are focused on water-mass oscillations and water hammer. Investigations for various exploitation regimes and different operating laws of the PRV's are adopted. Results are obtained by means of an original software developed for these analyses. The model was duly calibrated, and the results were compared with the results of the transient analyses from the original design phase of the existing HPP. | en |
