Design of coaxial high-speed gear reducer
Neklapil, Libor ; Ing. Tomáš Hubáček, Ph.D (referee) ; Bradáč, František (advisor)
The thesis deal with design of coaxial high-speed gear box for small-scale turboshaft engines. At the beginning a study of problems was performed and for design concept was elected version of single-shaft turbo-engine with electric generator. Kinematic diagram, type of gear design, material and lubrication method was designed. Further was solved proposal of basic gearing parameters, choice of the number of tooth and basic proposal calculations were performed. Was performed check calculation of gearing, calculation of bearings durability and was processed design documentation in required range. Designed gear reducer has two stage with three coutershafts, that are deployed evenly about main axis of reducer. First stage is gear with external gearing, second stage with internal gearing. The thesis may be used as a template for next similar gear reducers design.

Utilization of local systems for power system regulation
Kostov, Jiří ; Geschwinder, Lukáš (referee) ; Bartošík, Tomáš (advisor)
Bachelor’s Thesis deals general information about methods of regulation of elektrification systems, including basic principles of regulation of frequency, regulation of voltage and regulation of reactive and active power. Work includes information about aggregate remote control system, power plants that participate on regulation and self device for regulation and controlling of reactive power. Work engages on new options in section of regulation and his requirements for distribution sites. Part of work deals information about renewable natural energy sources and his requirements for distribution sites.

Simulation of micro hydro power plant with induction generator
Felcan, Matúš ; Bulín, Tomáš (referee) ; Huzlík, Rostislav (advisor)
The main focus of this work is understanding the importance of induction machines of small hydropower plants . Their principles and applications in practice. The use of asynchronous generators connected to the grid and in island mode. Created a literature search for hydropower plants and dynamic model of induction generator. Appropriately selected program Matlab to simulate asynchronous generators connected to the grid and also in the island mode.

Using the Arduino module to manage the physical model of the MVE
Perout, Miroslav ; Vrána, Michal (referee) ; Radil, Lukáš (advisor)
This bachelor thesis is focused on acquaintance with the model of MVE and creation of a proposal of the structure of management on the basis of the obtained information. In the first step, the differences in the generators used are described and explained. Subsequently, according to the parameters of the measured system, individual measuring elements and modules are designed to send information to the selected microprocessor. In the last step, the issue of creating visualization software through the Processing environment is discussed.
