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.
