An approximate model is introduced first, followed by numerical rigid water hammer models. Comparisons of the computed and measured results are examined for the transient load case of an emergency shutdown in Vrhovo hydroelectric power plant. The water hammer is mitigated by adjusting the guide vane and runner blade closing/opening laws properly. The results show a good agreement between the approximate and numerical and measured results"},{"@xml:lang":"sl","#text":"V prispevku raziskujemo učinkovitost in natančnost približnih in numeričnih modelov vodnega udara v slovenskih hidroelektrarnah s cevnimi turbinami na reki Savi.
