Testing of Control and Logic Functions of Feeder Terminal
Kaplanová, Klára ; Paar, Martin (referee) ; Orságová, Jaroslava (advisor)
This work occupies itself with an analysis of operational manipulations in the feeder terminal of the distribution system and it considers the configuration of its apparatus equipment with the following configuration of the logical operations for controlling the apparatus in the feeder terminal. Further, this work occupies itself with switching high voltage equipment, their qualities and distribution, with their electrically driven mechanism, including the method of their control. Moreover, the work is aimed at the configuration of the logical operation with the aid of the Boole functions for controlling the feeder terminal apparatus within the CAP 505 software, and at its following testing on the REF 543 terminal from the ABB Company. The aim of the work is theoretical analysis of controlling and operational manipulations in a high voltage distribution system, the following creation and registration of the blocking conditions as well as with their use to create a functional configuration of the feeder terminal of the distribution system and its testing on the demonstration panel which is set with the REF 543 terminal and with further apparatus equipment that simulates the complete high voltage distributor. In the factory configuration the simulation is carried out by the LOGO! module from the Siemens Company. Therefore, our further aim is to design and subsequently to connect the feeder terminal so that the controlling and signaling panel elements could be connected directly to inputs and outputs of REF 543 terminal and could so enable its controlling and checking of the operation conditions. The main aim of the work is to elaborate a detailed description of the functional configuration creation as well as the following REF 543 terminal adjustment for testing the blocking conditions.

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.

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.
