Energy Recovery from Exhaust Gases in an Electric-assisted Turbocharger for Hybrid Vehicles
Calábek, Daniel ; Kudláček, Petr (referee) ; Novotný, Pavel (advisor)
Obsahem této diplomové práce byla vhodnost využití turbodmychadla s přidruženým motor-generátorem pro vybrané typy hybridních vozidel a následná analýza energetických toků pro danou motorovou aplikaci. Přístup prezentovaný v práci zahrnuje termodynamický model motoru v programu GT-SUITE ve kterém jsou zkoumány možnosti energetických toků při změně velikost turbínového a kompresorového kola turbodmychadla. Přistup je aplikován na turbodmychadlo s variabní geometrií lopatek s přidruženým motor generátorem pro donáškové vozidlo, kde je možné při různých zatíženích motoru rekuperovat energii z turbodmychadla. Zároveň byli zjištěny možnosti snížení spotřeby paliva v určitých provozních bodech motoru.

Modification of a diesel generator for parallel operation with the grid
Černý, Martin ; Ctibor, Jiří (referee) ; Knobloch, Jan (advisor)
This works applies the idea of adjustment an engine-generator, so it is possible to connect an engine-generator, or other type of a generator, to the electricity. Consequently, the machine can transform the power supply without an outage. This work concerns the complex approach, provides the descriptions of particular parts, sensors and active components of a motor-generator and includes the explanation of their function. Further research is focused on designing and drawing a plan with a choice of a control unit for the whole system. Finally, the work deals with the complex implementation and testing the machine in real operation.

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.

Electrical system designs of the hotel complex with wellness
Veselý, Vít ; Bátora, Branislav (referee) ; Ptáček, Michal (advisor)
The bachelor thesis deals with the implementation of the technical solution - the distribution of the electrical network of the hotel with wellness. The theoretical part of the thesis presents an analysis of the basic elements used for the design of substations and busbars and introduces the basic computational apparatus for sizing transformers and lines. The practical part presents the various technical solutions for the design of the electrical network of the site, specifically addressing the design of low voltage (LV) cable lines for two variants providing 100 % backup of the electrical supply to the site and two other variants providing 50 % backup. In addition to the technical design of the individual options, the work also presents for each option their detailed financial budgets, including their overall economic comparison.
