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.

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.

Substation model with double busbar system
Kopáček, Petr ; Jurák, Viktor (referee) ; Wasserbauer, Vojtěch (advisor)
The goal of my Bachelor´s Thesis is to rebuild a single busbar medium voltage Switchgear substation model with two sections where one Switchgear cubicle represents the incoming breaker of the busbar section. Furtherly, the goal is to configure the model, test and put it into the operation for laboratory exercise. The base problems for model rebuild are described in the theoretical part which is followed by the description of rebuild for this particular case and solution of control and instruments interlocking configuration using CAP505 program. The updated drawings after the rebuild completion are attached. The conclusion of my Bachelor Thesis summarizes the problems identified during testing and their resolution. Few laboratory exercises are also included in the Thesis.

Partial discharge measurement of middle and high voltage cables
Pelikán, Luděk ; Wasserbauer, Vojtěch (referee) ; Krbal, Michal (advisor)
The main topic of this work is the analysis of the measurement of partial discharge measurements on high voltage cables. The thesis also deals with other measurements, including the measurement of the loss factor and the voltage retention and breakdown test. Part of the text describes the issue of partial discharge, its measurement by galvanic method and methods of elimination of disturbing influences that affect this method in terms of sensitivity and accuracy of the measured values. Thesis also describes the construction of the cables, their marking and the tests carried out on them. There is also a description of the cable terminals used for measuring, especially water terminals, which are designed for high voltages and which are carried out in the practical part of the thesis. The next part deals with problems prior to the commissioning of water terminals and their preparation for certain tests, including description and evaluation of the results of the measurements.

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.

Electric boiler connection in heat plant for providing ancillary services
Ditrych, Marek ; Příhoda, Martin (referee) ; Wasserbauer, Vojtěch (advisor)
The bachelor thesis deals with using the electric boiler for extension ancillary services in heating plant. The system and support services are described in the thesis, because the ancillary services regulate an energy deflection. The system and ancillary services are described in the thesis. Thanks to these services an energy deflection is regulated. The thesis describes different types of electric boilers and there functions. In the thesis is shown the possible solution of using an electric boiler in heating plant Opatovice. The cable conduction is designed for a power of electric boiler. For this reason, there is calculated the equivalent warming short-circuit current close to the electric boiler.

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.
