Design and production of sample panels with system installation Ego-n
Vašíček, Martin ; Bátora, Branislav (referee) ; Macháček, Jan (advisor)
The thesis deals with the development of systems for intelligent building, focused on wiring system, division of them and comparison of their differences. The advantages of these systems like comfort, energy reduction, etc. are also mentioned. Nowadays several standards of systems for intelligent building exist as KNX/EIB or LON, therefore thesis concerns to trade-off these standards too. Main part of the thesis is focused on system Egon made by company ABB where the system concept as well as bus modules are described that allow different functions, mutual connection of modules and their programming. Tutorial panel with ABB Ego-n wiring system, which will be used for study purpose, is designed in the practical part of the work. It includes scheme of the panel, electric linkage of components and photographs of constructed panel as documentation. In the final part of the work two examples of laboratory exercise for installation and setting are listed, including programming description.

ABB RobotStudio - robot control using PLC B&R Automation
Mittaš, Eduard ; Lacko, Branislav (referee) ; Lang, Stanislav (advisor)
The goal of this bachelor thesis is to demonstrate various ways of communication with the controller of the robot as well as consecutive controlling of this robot. The simulation will be achieved by using the TCP/IP protocol, while the communication in the laboratory with real equipment will be assured by Profinet bus. This thesis will show also another solution, which is simple communication and connection between Microsoft Visual Studio and Robotstudio by using TCP/IP protocol. Initial chapters will describe ABB and B&R Automation companies, their control systems, history and information associated with them. Following chapters will serve as a guide describing creating of application in each of three presented solutions.

Loss-of-excitation Protection for Synchronous Generator
Čáslava, Jiří ; Geschwinder, Lukáš (referee) ; Orságová, Jaroslava (advisor)
The aim of this work is to create a theoretical analysis of the problem of the exciting and de/exciting systems of synchronous alternators, an analysis of their functions and the problem of their disturbances, in connection with this being the following analysis of the asynchronous operation of the generator which appears with a big drop or with total loss of excitation. Further, it is necessary to carry out an analysis of the marginal loading and of the transient phenomena during the loss of excitation with the following summary of the knowledge and of the possibilities of the excitation loss diagnosis. The next task is to get acquainted with the possibilities how to protect machine protection terminal REM 543 produced by the ABB company, as well as with their following configuration and testing, for which we use the testing equipment of the protections TZO 3 produced by EGÚ Brno company. The primary goal of this work is to create a detailed direction for the calculation of the parameters necessary to put up the protection function UE6High of the REM 543 terminal, further to create the configuration of the protection communication and of the TZO 3 test device with PC, as well as to put up the REM 543 terminal including the putting up of the test TZO 3 device. The UE6High function works on the principle of the distance protection which is the most extended and the most effective to detect the loss of the synchronous alternator excitement. By means of the calculated values we carry out the putting up in order to pull out the MHO characteristic on the impedance level. The work also contains the measured values of the switch characteristic on the impedance level for various putting up of the rapidity of change of the excitement working quantities like voltage, current and phase shift measured within all three phases.

Optimization of powder-coating process resulting in a reduction of labor intensity of finishing components in gas insulated substation - GIS
Svoboda, Tomáš ; Kubíček, Jaroslav (referee) ; Strejček, Jan (advisor)
The diploma thesis deals with the optimization of powder-coating process resulting in a reduction of labor intensity during finishing components in gas insulated switchgear (GIS). The thesis is divided into five main chapters that describe characteristic and function of gas insulated switchgear (GIS), the theory of powder-coating, including mechanical and chemical pretreatment of surfaces, the studies of contemporary quality of coating process in the company ABB s.r.o. with classification of components of GIS according to their function. This chapter also contains detailed analysis of section of coating process during the processing of selected parts (housing and conductor). The thesis also contains detailed studies of masking of surfaces at coating parts, specifies the most common defects and determines the main cause presented in a well-arranged chart, design, description and realization of optimization solutions with selection and evaluation of final version. An economic comparison of contemporary condition of powder-coating process with designed optimization solution is stated at the end of the thesis.

Synchronization of Generator by Applied Synchro-check Relay in Feeder Terminal
Gregr, Tomáš ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
The aim of this work is a theoretical analysis of the parallel operation problems of electrical networks, as well as of the connecting the synchronous alternators to the electric power system. The knowledge of the present methods of connecting the synchronous alternators to the common network, of the historical evolution of this set of problems, of the phase conditions, their permitted deviations, as well as of the actual use of the modern phase automatic equipment, thereafter we to concentrate exclusively on the function of the synchro-check feeder terminal REF 543 produced by the ABB company. A part of this work is the analysis of the transient phenomena, that of accurate phasing, as well as that of phasing during a voltage, frequency and phase shift. Thereafter our goal is to get acquainted with the configuration program CAP 505, to carry out the communication of the REF 543 with PC, creating a new project, its configurating and then transmitting it to the REF 543 terminal. Further we occupy ourselves with the project to adjust the synchronous function synchro-check to phasing. The main task of this work is the proposal and the following testing of the connexion with the aim to test the synchronous function of the REF 543 terminal in cooperation with the output circuit breaker simulated on the test panel from the ABB company. Using the 6-phase generator from the UNIMA-KS company, this will simulate the voltage of the alternator. The network voltage is induced by means of the three-phase autotransformer from the Křižík n.p. company. We end this work up with a detailed description of connecting the terminal to the computer, with its following configuration, with setting up the required values, as well as with connecting the apparatus on order to test the conditions for the correct connection of the whole device.

The thesis includes diagnostics temperature field of industrial low voltage. Place of origin, flow and heat transfer are important aspects in the design of the switchgear, especially in terms of proper equipment layout. The correctness of the design of the switchgear is verified by measuring the practical temperature field during testing or in work mode. To determine the temperature profile, it is necessary to measure the temperature at various points of the switchgear, either contact or contactless method. Measurements are performed on standardized low voltage switchboards, which are located power elements. The goal is to replace costly and time-consuming field testing switchgear efficient simulation of the temperature field mathematical model developed switchboards.
