Data reconciliation of energy processes
Nováček, Adam ; Kuba, Pavel (referee) ; Touš, Michal (advisor)
This thesis is focused on problem data reconciliation of measurements. The objective of this thesis was reconciled measured value from electric drum dryer to suit exactly to the mathematical model of drying. For solution was used nonlinear data reconciliation with constrained nonlinear optimization. The entire calculation is processed in programme MATLAB and outputs are graphs of reconciled values of measurement on dryer such as inlet and outlet temperature and humidity, differential pressure of exhaust moisture air, weight of laundry, atmospheric pressure and electric supply. Achieved solution can by characterized by an amount of evaporated water. Weight of wet and dry laundry are 27,7 kg a 17,7 kg. The calculated amount of evaporated water from measurements was almost 18,8 kg. With reconciled measurements it was 9,7 kg. Goals of the thesis were found more realistic values.

Protection for Generator Unbalance
Kuba, Petr ; Paar, Martin (referee) ; Orságová, Jaroslava (advisor)
The thesis deals with the problem of unbalance in generators and discusses various means of generator protection against the effects caused by this abnormal working condition. The general importance of the problem is described in the introductory part of this work. The theoretical section of the thesis contains an analysis of procedures applied to solve different types of unbalance by the help of the method of symmetrical components. As a central aspect of the topic, the causes of unbalance are examined. This investigation is realized together with a close insight into the diverse possibilities of unbalance reduction and, importantly, in respect the effects of negative sequence current on a generator and its components. The principles of generator protection against unbalance are described at the end of this section. In its practical part, this work deals with the procedure of protection setting and testing. The applied protection is an actual component of the REM 543 machine terminal as made by the ABB company. In order to facilitate the testing of the protection, we used the TZO3 electrical protection testing device provided by the EGÚ Brno, a. s. company. A summary of the most important information and measurement results can be found in the final part of the thesis.

Stabilized operation and short-circuit conditions within E.ON 110kV power network supplied from Otrokovice 110kV switching station, during the period of 2012
Kuba, Petr ; Rampl, Martin (referee) ; Blažek, Vladimír (advisor)
This thesis deals with steady running and short-circuit conditions in the 110 kV network, E. ON, fed from 110 kV Otrokovice. Substation Otrokovice ensures system transformation from 400 kV to 110 kV system through three transformers. In order to increase reliability of power supply and improved economy is considered to bridge the transition from the operation of two transformers in bridge operations of the three transformers. However, this brings with it significant worsening of short-circuit conditions in the 110 kV network. The task of this work is to evaluate and compare the two variants of operation in terms of steady running and short-circuit conditions in the network at 110 kV and then implement operational and technical measures. The introduction describes the electricity system and its parts. The theoretical part of the paper discusses ways of dealing with steady running and short circuit conditions of long lines. Practical part will deal with applications of knowledge on the network. The conclusion summarizes the most relevant information and the results assessed both variants.

Energy sources and consumption
Majer, Jan ; Kuba, Pavel (referee) ; Bobák, Petr (advisor)
The thesis describes basic methods of producing energy and presents the basic division and characterize sources of energy. It compares and describes the production of energy in the Czech Republic and the United States of America. The thesis explains, where and how is this energy consumed and presents energy production and consumption in the Czech republic and in the United States of Amerika and provides a comparison of the two countries. Indicates the percentage of consumption in various sectors in these countries and the distribution of energy consumed by resource used. The thesis is also focused on the comparison of household consumption in the Czech Republic and the United States of America. It specifies the average household consumption of Prague and New York and investigates the causes of the difference in average household consumption of both countries.

Design of experiment on a washer extractor
Těthal, Josef ; Šomplák, Radovan (referee) ; Kuba, Pavel (advisor)
This bachelor thesis deals in the first part with research regarding the laundry process and introduction to design of experiments. The next part, which is the output of this work, describes an experiment made. The experiment defines the impact of rinsing temperature and spin speeds on consequential humidity of the laundry.
