Economic view of the fast closing valve selection for HPP Vranov

By Ondřej Gipka

Abstract

The thesis deals with the evaluation of the investment in the fast closing valve replacement in The dam Vranov using Computational fluid dynamics (CFD). The final effects of the fast closing valve replacement will be examined on three different types of valves with regard to the turbine output in operation zone and without the influence of water intake runner and turbine draft tube. The aim of the thesis is to theoretically evaluate alternatives of the fast closing valve replacement and define its basic characteristics and classifications
