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.

Measurement of three-wire transformer parameters
Kováč, Frederik ; Bukvišová, Zuzana (referee) ; Wasserbauer, Vojtěch (advisor)
Thebachelor’sthesisdealswithmeasuringsymmetriccomponentalimpedanciesofthree winding transformer. Thesis is divided into a theoretical and practical part. In theoretical part is described principle of transformer operation, its parameters, open-circuited and short-circuited measuring, measuring of zero-sequence impedance and connection schemes. Practical part deals with design of workplace in laboratory, description of used instruments and practical measurements with real connection schemes. For measuring parameters of three winding transformer is created a laboratory instruction manual.

Concept of smart home energy monitoring and management
Kolouch, Petr ; Wasserbauer, Vojtěch (referee) ; Vrána, Michal (advisor)
This bachelor thesis deals with smart metering of home. The introduction of the thesis deals with the approach of this issue. It then explains the principle of smart socket operation and the possibility of linking smart sockets with renewable sources. In the next part of the thesis there is a thorough search of existing smart systems in the Czech Republic and abroad. In the practical part, 3 commercial smart sockets were measured and evaluated. The last part is the creation of the concept of smart socket-based on microchip ADE7753. Subsequently, the implementation of the measuring device is detaily described.

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.

Plan of grid connection for small hydroelectric power plant
Miškovský, Ján ; Wasserbauer, Vojtěch (referee) ; Radil, Lukáš (advisor)
The purpose of the thesis is a plan of grid connection for a small hydroelectric power plant in Rastak. The introduction briefly analyses the scheme, MVE, description of the particular constructive parts and specified technical equipment as well. The main goals of the study were choice of suitable transformer, the proper VN substation as well as a plan of overhead power lines. Particular attention was paid to: figuring the short circuit current and mechanical strain, the best choice of electric field VN substation for MVE, the transformer connection in the point VN substation and geometrical measurement of its power line with 35 kV voltage summing up, it can be concluded that above mentioned is crucial to cooling of the transformer in Raštak.

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.

System of Protection for Laboratory Generator Set
Jurák, Viktor ; Wasserbauer, Vojtěch (referee) ; Orságová, Jaroslava (advisor)
This thesis deals with draft of protection synchronous generator. The introduction of this thesis is devoted to the description of the laboratory generator set and to the comparison of the devices – protection terminals and measuring devices - which can be used for its protection. In the practical part, it is designed to protect the laboratory generator by means of the selected protection terminal and the way it is connected to the generator circuit so as to enable the generator to be shut down in case of a fault. The last part is dedicated to the configuration, parameterization and testing of the protection terminal.
