Design of electrical substation for office building
Ličman, Petr ; Ptáček, Michal (referee) ; Novotný, Jan (advisor)
This bachelor thesis describes a design of an electrical substation for office building. The first part deals with requirements for the supply of electricity and its quality. Because of the possibility of power supply interruption, the thesis also addresses the use of alternative sources. These can be divided into static sources (UPS) and rotating sources (motor-generator). The thesis also focuses on the issue of auto-switching power sources. In the practical part, the main power distribution of the building is designed, which also contains the main elements such as high-voltage switchgear, transformer, motor-generator and UPS. Focus on alternative sources has led to creating two variants of a backup system.

The assessment of advantages of construction of large hydroelectric power plants in the area of Cukrova bouda, district Sumperk
Knápek, Michal ; Kopřiva,, Miroslav (referee) ; Mastný, Petr (advisor)
The subject matter of the master´s thesis is, in particular, an evaluation of the advantageousness of the construction of a pumped-storage hydroelectric power station in the vicinity of Cukrová Bouda. In the master´s thesis introduction the utilisation of pumped-storage hydroelectric power stations in providing reserve power generation to the operator of a power transmission system is discussed. The thesis then focuses on a technical design solution where two alternatives are drawn up for which the nominal parameters of individual designs for a pumped-storage hydroelectric power station are specified. The following part deals with the impact of the structure and the plant’s subsequent operation on the environment. A further key part is the determination of investment and subsequent operating costs and an evaluation of the plant according to economic pointers. The final part of the master´s thesis contains a SWOT analysis and an assumed programme of works for the plant’s preparation and actual construction. The conclusion contains an overall evaluation.
