Stabilized operation and short - circuit conditions within E.ON 110 kV power network supplied from Slavětice 110 kV switching station, during the period of 2011
Nábělek, Ondřej ; Rampl, Martin (referee) ; Blažek, Vladimír (advisor)
In the Master Thesis discusses the impact of the bridge connecting the transformer to power system connection to a separate transformers. They were first analyzed the method of calculating the steady operation of the network using the Newton iterative method and the method of calculating short-circuit ratios. It describes the area Slavětice 110kV substation, which is the subject of subsequent calculations. It is also elucidating the function of the bridge connection, advantages and disadvantages. The reason for implementing the bridge operation is to increase the reliability of electricity supply to customers but the major disadvantage is the greater technical and economic performance because increased short circuit current and the need for transmission transformer 400/110kV same type with the same parameters. Point is the practical part, which contains already concrete results taken with the dispatcher software Sinaut. There is a short-circuit resistance compared to short-circuit power substation, then the burden of the elements (transformers, lines) for two specified connection alternatives and four interruptions important elements. Finally, it stated that it can be done with the bridge connection which technical measures. It was discovered that in terms of short-circuit ratios in the present time it is not possible to operate the bridge connection transformers substation Slavětice 110kV and in terms of very different parameters of transformers 400/110kV the operation is not recommended.
3D machining module
Horák, Michal ; Omes, Jiří (referee) ; Dokoupil, Vladimír (advisor)
The thesis deals with choosing the appropriate conception for a 3D CNC machining module, design, and construction of the given machine. This work is laid out into several parts that deal with automated production assemblies, appropriate construction alternate design, design of the selected machining module, and FEM method.
Detection of the border between North and South Europe by using mental maps
ŠTEMBERK, Martin
The bachelor thesis deals with the detection of the borders of North and South Europe by using mental maps. The whole elaboration was created with the participation of nine European countries, which represent Central, Western and Eastern Europe. Altogether, the research involves more than 300 respondents who visit European universities in selected countries. Various display variants, such as line or polygon, were later used to work with mental maps. The work also deals with the centre of Europe and the dominant elements of creating mental maps. The data were processed via ArcGis Pro. The work aims to analyze the results, compare the individual lines and create the borders of North and South Europe. Finally, it responds to the results that are delived from the practical part of the work.
