Analysis ofelectrical output from the power plat working in the middle of town
Hrubý, Radek ; Brno,, Luděk Ondroušek - Teplárny (referee) ; Matoušek, Antonín (advisor)
The work focuses on outlet of the electrical power from power plants operating in urban areas. After a short analysis of the general possibility of leading out electric power from power plants of various types, thesis continues to describe of outlet electrical power from PPC Červený Mlýn. Subsequently, are calculated short-circuit conditions in the main switching station. It follows an analysis of power lines. The last part dealt with the issue of reliability of sources in connection with random transition processes in the electrical network and the light of the operational reliability of electrical power equipment.

Simulation of small single-phase transformer
Nevřivý, Tomáš ; Hájek, Vítězslav (referee) ; Vítek, Ondřej (advisor)
This bachelor‘s thesis deals with the complex design of single-phase transformer for low power transfer. The basis of the work is procedure of design referred to standardized tables together with the analytical calculation of all transformer parameters. The calculated parameters are verified using by finite element method in the environment of the program FEMM. Analytical calculation is verified by simulation in stationary and quasistationary magnetic field. The conclusion of the work is supplemented by measurement of the transformer, which according to the calculated parameters was made by company of ELEKTROKOV, Inc.

Optimalization of vibration microgenerator
Kurfűrst, Jiří ; Hadaš, Zdeněk (referee) ; Ondrůšek, Čestmír (advisor)
The article describes how to produce energy necessary for sensor supply. These generators are used as a local source operating on vibratory principle. Mechanical vibrations that occur in moving machines, in nature etc. are used in order to gain required energy. So are kinesis principles and analysis employed in some of the avaible generators. It also contains patent and literary background research. Work is oriented to solving mechatronic perimeter, in the concrete micro - generator. Mechatronic perimeter piles from seat power control parts and mechanical parts, where common solving equation system leads to correct solving. Mentioned analyses be of consequence for usage optimization methods artificial intelligence. Optimization method are used on optimum solving proposal micro - generator. To inquest dynamism system was used program Simulink (part of MATLAB), generator is buckthorn for f = 17 [Hz] acceleration yam = 0,5g [ms-2]. As a algorithm is used SOMA – All to one.

Design, optimization and full load circuit simulation of the surface mounted permanent magnet machine
Bláha, Martin ; Ondrůšek, Čestmír (referee) ; Kurfűrst, Jiří (advisor)
This thesis deals with the possibility of using the finite elements method for the analysing of synchronous permanent magnets machines. The aim of this work is to discuss the possibility of the machine design more effectively with using the finite elements method and Maxwell software for the simulations. On the created parametric model, simulations were performed according to master thesis assignment. The aim of this work is to determine induced voltage, iron losses, machine inductances and make a permanent magnets demagnetization analysis. From simulations results the machine efficiency is calculated. The parametric model was used for the optimization of selected parameters. From results of optimization new dimensions of permanent magnets was obtained. Machine efficiency was increased by new permanent magnet material and optimized design.

Electromagnetic damper
Mikyska, Jan ; Huzlík, Rostislav (referee) ; Ondrůšek, Čestmír (advisor)
This master´s thesis is focused on obtaining electrical energy from vibration control car using electromagnetic dampers. The primary use of the electromagnetic damper is the production of electrical energy, which can then be used to power electrical appliances in your car or battery charging. The thesis is divided into six main parts: a literature review of possible ways of getting electricity from the car damping, theoretical and mathematical analysis of problems, the choice of design with computational analysis of dampers and power calculation.
