Abstract:This paper deals with critical flow regimes that may induce an unacceptable water hammer in the Sava River Kaplan turbine hydropower plants. The rigid water hammer model is introduced first. The computational results are then compared with the results of measurements in two distinct hydropower plants (HPP): (i) The refurbished and upgraded Medvode HPP, and (ii) The newest Brežice HPP. Comparisons of the computed and measured results are examined for normal operating regimes. The water hammer in the two power plants is controlled by appropriate adjustment of the wicket gates and runner blades closing/opening manoeuvres. The agreement between the computed and measured results is reasonable.

Title:Teoretične in eksperimentalne raziskave vodnega udara v hidroelektrnah s Kaplanovimi turbinami na reki Savi
Abstract:Prispevek obravnava kritične pretočne režime, ki lahko povzročijo nesprejemljiv vodni udar v hidroelektrarnah s Kaplanovo turbino na reki Savi. Najprej je predstavljen model togega vodnega udara. Računske rezultate nato primerjamo z rezultati meritev v dveh značilnih hidroelektrarnah (HE): (i) prenovljeni in nadgrajeni HE Medvode ter (ii) najnovejši HE Brežice. Primerjave izračunanih in izmerjenih rezultatov so podane za normalne režime obratovanja. Vodni udar v obeh elektrarnah je krmiljen z ustrezno nastavitvijo manevrov zapiranja oziroma odpiranja vodilnih in gonilnih lopatic turbine. Ujemanje med izračunanimi in izmerjenimi rezultati je dobro.
