Protection functions of the REX 640 terminal in case of earth faults
Siegel, Josef ; Bukvišová, Zuzana (referee) ; Wasserbauer, Vojtěch (advisor)
This bachelor thesis deals with the protection, implementation and evaluation of test for fault condition indicators. Thesis focus on earth fault indicators. These protections must be able to evaluate earth faults in compensated, compensated with auxiliary resistor, unearthed and high-resistance earthed networks. Furthermore, part of the thesis is research of methods of earth fault detection, including their principles and function description.

Design of reconstruction the part of the LV distribution network including make the creation of Detail Design Documentation
Kubeša, Radek ; Wasserbauer, Vojtěch (referee) ; Bátora, Branislav (advisor)
This master’s thesis deals with problems associated with the design of LV distribution networks. In the theoretical part there are described, legislative requirements for the designer of distribution networks, overwiev of standards in which the designer should have oriented and programs used in practice to create design documentation. In the next part there are given requirements for the detail design documentation. Practical part of master’s thesis is devoted to design of reconstruction of distribution network in the given part of village. Appraisal of existing a newly design distribution network was done by calculating of stady state in the BIZON program. In the last part there is listed design documentation for construction in range for the smooth implementation of the project.

Operation of embedded cable lines into HV distribution grid
Černý, Tomáš ; Wasserbauer, Vojtěch (referee) ; Ptáček, Michal (advisor)
The thesis focuses on a section of cable line inserted into overhead high voltage power line. The essence is a description of the benefits, risks and impacts of the operation of such sections in terms of protection, transition processes. etc. The thesis also includes economical comparison of an acquisition and operating costs of both overhead and cable line. The topic of this thesis was given by ČEZ Distribuce a.s.

Use of the MAWIS Photo solution for data collection and creation of 3D building models
Viktorin, Tomáš ; Wasserbauer, Vojtěch (referee) ; Ptáček, Michal (advisor)
This bachelor thesis deals with the use of the MAWIS Photo service for data collection and creation of 3D models with a specific focus on cable routes. In this context, the thesis provides a basic overview of the legislation and technical standards relevant to the implementation of projects and the control of cable route construction. It also focuses on a detailed description of the MAWIS Photo web application, including it`s usability, basic principles of operation, advantages and disadvantages. The thesis also discusses GIS systems and surveying in relation to energy construction. In the practical part of the thesis, the applicability of the application in practice is verified, specifically the description of the measured cable route, measurements, creation of a 3D model of the structure, subsequent creation of drawing documentation and evaluation of the achieved results. Following the direct experience gained with the use of MAWIS Photo application, the thesis also provides a critical evaluation of the applicability of the application itself in the practice of power structures.

Reconstruction of a transformer station with a substation for auxiliary systems
Novický, Marek ; Wasserbauer, Vojtěch (referee) ; Jurák, Viktor (advisor)
The master thesis deals with the premises of the Staré Brno heating plant, where there are two 22 / 0,4 kV transformers used to supply the heating plant's auxiliary system. The thesis deals with theoretical areas related to the planned design. After theoretical section is following a detailed description of the recent state of HV and LV substations and transformers. The scope of work is the design of new transformers, HV substations and LV substations, central compensation. At the end of the thesis is discussed the economic side of transformers.

Extensible measurement socket placement optimalization with respect to the higher number of conductors
Šindler, Matěj ; Čepička, Martin (referee) ; Wasserbauer, Vojtěch (advisor)
In opening, this bachelor thesis is describing structure and basic block description of UniGear switchgear manufactured by ABB company. Then this thesis focus on current and voltage transformers and sensors often used in this type of switchgear. Main part of this thesis is dedicated to evolution and description of connector, used in connection solution of withdrawable metering unit with low-voltage compartment. Next part states the main requirements for new connector, that will replace current connector in future solution. In following part there is a list of different options for new connector with their biggest strengths and weaknesses pointed out. Then there is list of alternative placements for new connector. In final part is chosen and described new connector and its placement. This solution is valuated and backed up by created 3D models.

Utilization of SINCAL tool in the field of network protection
Rampák, Dominik ; Wasserbauer, Vojtěch (referee) ; Topolánek, David (advisor)
This bachelor thesis is describing the basics of using program PSS SINCAL for protection of distribution networks. The thesis is divided into 3 parts. The first part is describing basics and functions of the program. The second part is devoted to the moduls, work with moduls described in form of manuals. The last part is describing creation of test network and simulation of single-phase to ground short-circuit to verify selectivity of the protection devices.
