Design the Transformer Station for the Outgoing Power of Cogeneration Unit
Pastorek, Jaroslav ; Procházka, Aleš (referee) ; Orságová, Jaroslava (advisor)
The thesis deals with the design of a transformer station for the outgoing power of cogeneration unit with an electric capacity of up to 1 MW. The thesis describes the design procedure of individual devices such as a transformer with a nominal ratio 22/0,4 kV, high voltage switchgears and low voltage switchgears. With the proper selection of the transformer, along with the technical parameters, the economic benefits that come from its purchasing and operating costs with the transformer operation are also considered. Based on this, the economic comparison of selected types of oil transformers during 20 years is also developed. Another part of the thesis deals with HV and LV switchgears, which are dimensioned according to shortcircuit conditions in the transformer station. In conclusion this work deals with the grounding of a transformer station and design protection in accordance PPDS.

Comparison of design classic and smart wiring of house
Valo, Marek ; Novotný, Jan (referee) ; Bátora, Branislav (advisor)
This work contains requirements for the design of high-voltage and low-voltage classic and smart wiring. The aim of this work is to implement a project of classic and smart wiring for house and their subsequent comparison. In the beginning is introduction to wiring as such, insight into history, a brief presentation of contemporary species of wiring. The following chapter provides an analysis of high-voltage systems and criteria in its designing, which is based on the currently valid standards. The chapter contains also a brief excerpt dealing with ways of storing wires in buildings and installation zones individual rooms. Chapter of system wiring briefly describes the idea of this kind of wiring and its function. Introduction is focused on explanations of the system wiring, then the chapter directed to a specific producer used in the design of the project itself. In the chapter number five the problem of low voltage wiring and methods for their design are analysed. The following section deals with the design of wiring own project (classic and system) for a family house, designing switchboard, budgeting and technical reports. In conclusion, these two types of wiring are compared in terms of design, project documentation and budget. The practical part is dedicated to creating drawings containing high-voltage and low voltage wiring, switchboard scheme, budget, calculating illuminance and technical reports. The project documentation is discussed further in the technical report.

Evaluation of industrial heritage
Navrátil, Oldřich ; Králová, Eva (referee) ; Zemánek, Václav (referee) ; Ryšková, Michaela (referee) ; Zemánková, Helena (advisor)
The main subject is evaluation of effective use in terms of care (not only within protection of monuments) in order to save and protect industrial heritage. Pointing out on critical issues connected with the end of production of traditional branches which played the key role in historical development of our cities. Nowadays abandoned buildings and sites are represented by memory of the place or its prosperity. New owners often don't share the positive approach to the industrial heritage, developers are seeking new sites, cities and inhabitants have developed new needs through the time. The work will demonstrate examples within European context and will make recommendations in monitoring and classification of industrial heritage to prevent undo able losses.

Methodology of identification of revisions and inspections of technical equipment for a manufacturing company based on the requirements of ISO 45001
Valenta, Jakub ; Jandová, Kristýna (referee) ; Bača, Petr (advisor)
This work deals with the issue of inspections and revisions of technical equipment according to safe operation standards on the basis of OSH and FP requirements. In the introduction, these fields of work safety and fire protection are described, which will be used in later parts of the work. Subsequently, the term „technical equipment“ and subcategories of this issue are defined, with each of the subcategories being specifically approached. As a result, the thesis describes why it is necessary to regularly inspect the technical equipment, while the individual types of inspections are subsequently defined. This is accompanied by the distribution of the person’s rights to carry out individual inspections and the distribution of responsibility for the inspections carried out. The acquired knowledge is then used to create a model of the process of regulation of inspections and revisions and to create an overview of periodic inspections and revisions of technical equipment for a manufacturing company. This model and review of inspections are then considered the output of this bachelor’s thesis.

Effective Integration of PCM 30U OCH into Laboratory Education
Procházka, Jiří ; Atassi, Hicham (referee) ; Škorpil, Vladislav (advisor)
The aim of my bacherol’s thesis was to introduce with problemation of PCM, especially PCM 1. class and their practical use by instalation of equipment PCM30U. The project includes description of transmission equiment possibilites of its praticable setting of intertable cards and basic units. The result of my thesis is suggestion for completing new laboratory exercises for the subject Access and transport networks. The first assignment creates so called “hot line” between two localities connected by E1 line. This option is used e.g. by railway system for dispatching control. The second assignment simulates checking measurement of the optical part of PCM30U, transmitting and receiving part of board JRO. This measurement is important for setting the device when suggesting the fitting and also for regular measurement showing the status of laser or optical connection. The third assignment shows the possibilities of setting and using the order board PBS in PCM30U-OCH. This card is often used in power engineering for transfer of protections and control signals.

Individual stand-by of incoming feeder of Energetika Trinecs´ 6 kV substation
Borski, Roman ; Hodula, Petr (referee) ; Topolánek, David (advisor)
The thesis titled Individual stand-by of incoming feeder of Energetika Třinec 6 kV substantion is theoreticaly and practically concived work that offers comprehensive information on automatic standby focused on the selected operation of Energetika Třinec. At present, the standby is in authention mode and thesis solves shutdown of transformer T5. The extract of automatic device indicates trouble-free operation and thesis focus on the power take-off for transformer T5. The theoretical part provides information about problems of own comsumption of power plants, automatic device of standby and protection of electrical equipment. Thesis also sloves the protection settings, which is supported by calculations of short-circuit currents. The practical part is formed from the suggestion of solution in accordance to current criteria and the evaluation of possible settings of protective automatic devices together with an assessment of implementation option of standby. The aim of the thesis is to perform analysis of standby and evaluate effects which causes shutdown of own comsumption part. The final part assesses current settings of protection based on calculated values. Existing protections are unsuitable and it is recomennded to deploy digital multi-stage protections as a replacement for present relay protections.

The Active Bonnet Hinge
Galda, Michal ; Růžička, Bronislav (referee) ; Brandejs, Jan (advisor)
This thesis deals with designing the construction of an active bonnet hinge, tuning the kinematics and appropriate proportioning of individual parts of the hinge. The thesis consists of two main parts – the first part is an analysis of the current state of knowledge and the second part presents a designing the construction. The active hinge should serve as a safety element in automobiles to minimize consequences of head injury suffered during the collision of a pedestrian with an automobile.
