The storage water plants problem appreciation
Archalous, Jakub ; Himr, Daniel (referee) ; Sloupenský, Zdeněk (advisor)
This bachelor’s thesis deals with the use of hydropower. It gives an overview of hydroelectric plants and describes mechanisms that convert water energy into electric energy. The most attention is paid to the principle and operation of pumped storage power plants and the machinery used there. Also the efficiency of the pumping cycle at Dlouhe Strane power plant is calculated.
Pump storage station
Šimek, Petr ; Sloupenský, Zdeněk (referee) ; Kubálek, Jiří (advisor)
This bachelor thesis deals with the functions of hydro-power plants, describes the various machinery and their distribution according to the parameters of use. Outlines the calculation in the design of hydraulic machines. There are also descriptions of machine layout and their use in praktice. For the particular case, there is prepared hydro power plant Dlouhé stráně. Related topic that is included here, the electricity system and the daily load diagram.
Small hydro-power plant
Jedlička, Rostislav ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)

Adaptation of the Watermill
Pavlík, Jan ; Hudec, Martin (referee) ; Klas, Roman (advisor)
The bachelor´s thesis is composed of two parts. In the first part, there is a generally discourse about small water power plants, their structural design, mechanical equipment and economical efficiency and its function is to create the basic conception of the waterwork. The second one deals concretely with the small water power plant in Crhov, that was rebuilt from the original mill by Mr. Petr König in 1990s.

Chromý, Hynek ; Špano,, Miroslav (referee) ; Dráb, Aleš (advisor)
The goal of the work is to find suitable soulition for a small water plant in kontinuity of a projekt of damaged dam repair
Contactless Measuring Method of Blade Vibration during Increasing Turbine Operational Speed
Procházka, Pavel ; Vaněk, František ; Cibulka, Jan ; Bula, Vítězslav
A novel method for contactless measurements of turbine blade vibration during increasing or decreasing operational speed is presented. The method is based on the evaluation the time differences of blade tips passing along contactless sensors placed on the stator, and the substitution data correction using a numerical model. The method has been verified both numerically and experimentally. For the experimental research on the model bladed wheel of the Institute of Thermomechanics and subsequent applications in operating conditions, two new types of sensors functioning on the magnetoresistive and induction principle have been developed.

Procházka, Pavel ; Vaněk, František
The report contains the results of the design and implementation of a contactless vibrodiagnostic system for monitoring low-pressure turbine blades vibration of TG2 NPP Temelin. Results of the trial operation of the system are included.
The Measurement of Vibration of Low-Pressure Rotor Blades on TG2 ETE part 3, VYZ/TZ 56/107
Procházka, Pavel ; Vaněk, František
The report extends the results of the design and implementation of a contactless vibrodiagnostic system for monitoring low-pressure turbine blades vibration of TG2 NPP Temelin. The results of measurements, including start-up turbine performance, are summarized and discussed.
Aerodynamika špičkového řezu turbínové lopatky 1220mm
Synáč, J. ; Rudas, B. ; Šťastný, M. ; Luxa, Martin ; Šimurda, David ; Šafařík, Pavel
The paperis focused on aerodynamic characteristics of the tip section of a steam turbine last stage rotor blade with an active span 12200mm (48").
An improvement of the vibrodiagnostic system for research of rotating machine parts vibration
Procházka, Pavel ; Vaněk, František ; Pešek, Luděk ; Cibulka, Jan ; Vaněk, Petr
Methods of frequency analysis of rotating turbine blade vibration from tip-timing measurements are discussed. Procedures for increasing in accuracy of amplitude and frequency evaluations of blade vibration are suggested. Optimization of sensor positioning of a multi-channel vibrodiagnostic system has been solved by means of numerical and experimental modeling. A novel method for axial rotor displacements measurement is presented.
