Measuring system for laboratory generator unit
Pochop, Zbyněk ; Ptáček, Michal (referee) ; Orságová, Jaroslava (advisor)
This Master thesis deals with the measurement and description of the synchronous generator , which is located in laboratories. First, the thesis deals with the theory of synchronous machines. This is followed by a detailed description of the involvement of laboratory genetatory unit. Subsequently, the work deals with the measurement of basic parameters of the synchronous machine and also quite thoroughly devoted to displaying transients at various levels on the digital oscilloscope. The dissertation aims to compare theoretical ideas with the measured results. Finally, it is shown what could be measured next to the generator set.

Integral quality criteria of regulation
Gruna, Jiří ; Cejpek, Zdeněk (referee) ; Dosoudilová, Monika (advisor)
This bachelor’s thesis deals with the assessment of the quality of regulation using integral criteria. In the first part we are interested in the basic theory of regulation needed to understand the problem. It includes a description of the control system, differential equations in the theory of transfer function, types of regulators and addresses the question of stability. In the second part the thesis introduces the integral criteria. Using their area, we assess the quality of regulation. For clarity, the criteria are supplemented by examples to show their advantages and disadvantages.

Didactic program for transient analysis
Kříž, Petr ; Murina, Milan (referee) ; Sedláček, Jiří (advisor)
The aim of this work is to create didactic program for transient analysis in the environment of C++ Builder. For the disposal we have pre-defined bank of inertial circuits, that we can change at will and enlarge with the help of implemented editor of circuits. If we want to make an analysis, we will choose random circuit from offered palette and put in our values of components RLC. Subsequently, we specify if we want to know ´image´ of function F(p) of impulse or transient characteristic, finally we push the button ´Execute´. The program will display demanded ´image´ of function F(p) and simultaneously figure out ´original´ of function f(t) with the help of implemented Heavisides figures. This function is acceptable for display in time, which make this program enable. It is easy to find out by the change of time axis, when comes to stabilization of transient analysis and with the help of moving cross exactly establish in which time it has happened and what is the value of transmission, voltage or current in the curciut at the moment. Achievement results shall be print out.

Organic electronics for biosensors
Netočný, Martin ; Vala, Martin (referee) ; Salyk, Ota (advisor)
In the first part are discussed the organic thin-film transistors and their possible use for chemical and biological sensors. Middle section discusses the electrical properties of OECT device in steady-state and transient behaviour and potential use of OECT for cell monitoring. The final experimental part deals with influence of temperature, aging, electrolyte environment and geometry on the function of OECT device.

Models of distribution systems integrating distributed resources in PSCAD and simulation of chosen operational regimes
Bezecný, Ján ; Kopička, Marek ; Drápela, Jiří
The content of this Master´s Thesis is creating of dynamic models of distributed energy sources in PSCAD and their validation in chosen operation regimes. In the introduction of this thesis is summarized theoretical knowledge about methods for power systems analysis and there is a comparison of static and dynamic methods for power systems analysis. Static methods are used to calculate electric variables in grid nodes. In compare with them, dynamic methods are used to study instantaneous electrical and mechanical variables not only in grid nodes, but also at components of power system. Secondly, we individually designed distributed energy sources in according to requirements, we made a topology of distribution grid and we integrated these energy sources to the distribution grid. Finally, we chose some operation regimes, and studied a behavior of energy sources during these operation regimes.
