The small hydroelectric power station design
Kokeš, Petr ; Pěcha, Jiří (referee) ; Matoušek, Antonín (advisor)
The thesis deals with comprehensive design of the small hydroelectric power station in the particular site. There is the site description in the first part followed by evaluation of the hydroenergetic capacity of the watercourse and description of the inlet building and piping. Building and machinery part of the turbine hall is described in the next part. The electric part of the power station is worked up to wider scope and includes hydroalternator, switchgears incl. power for self-consumption, electric protections, cabling, transformer substation and high voltage inlet line. There is a description of the control system in the next part and economical evaluation of the investment is at the end.

The manufacturing of the aluminium-zinc coated steel sheet transformer
Sykáček, Jiří ; Šlais, Miroslav (referee) ; Císařová, Michaela (advisor)
The project developed in within the framework of Magister ´s studies of field M-STM is elaborated to meet customer requirements for manufacture of transformer station, which is intended for use in photovoltaic power station. Design and drawing documentation were prepared using 3D CAD System Solid Edge. Self-supporting frame of the transformer station welded from separate parts made from alu/zinc plates is in the form of a technological unit, which is equiped with electrical technology needed for safe and failure-free operation of the power station. It deals with technology of components production, including subsequent process of hard soldering and surface finishing. As the best solution was chosen processing of forming punching and using brake press. Chosen production methods are assessed not only form point of view of used technology, including the technical pitfalls associated with processing of alu/zinc plates, but also in terms of economic costs of manufacture throughout the transformer station. The forming processes are made using punching press TRUMPF TC200R, with rated shear force of 165 kN and brake press URSVIKEN Optiflex with rated compressive force 1 300 kN. Forming tools are optimally selected according to parameters of different types of parts. Finally, it compares the technical-economic aspects of production transformer station made of alu/zinc plates compared with whole-concrete construction of the station using bell-casting method.

Creation of customer transformer station database in SharePoint
TINAVSKÝ, Milan
Creation of a database of customer substations in SharePoint environment. The Scrum development method will be used for development. The database will be split into several relational linked lists, so that it follows the normal form of databases 1-3. Standard SharePoint tools such as views, forms, or dynamic filtering will be used in the development of the database. Using an extension from Nintex, a workflow will be created to monitor the expiration of contracts. Data will be imported from excel spreadsheets.
