Project of Logical Busbar Protection
 Kulač, Ivan ; Paar, Martin (referee) ; Orságová, Jaroslava (advisor)
The main objective of master‘s thesis was creation logical overcurrent busbar protection. The first part of document describes teaching test panels with ABB REF feeder protection´s terminals. These panels are installed in Laboratory of electrical protections at Department of electrical power engineering, Faculty of electrical engineering and communication, Brno University of technology. On these panels we can simulate the real involvement of the distribution station. Were subsequently describes used digital protection´s terminals REF 543. Then was designed configuration of these panels so to achieve logical busbar protection, which will be able to assess the short circuit fault and shut the smallest part of the busbar system. Within the configuration it was necessary to solve the cooperation of protection terminals. This was finally accomplished through connecting wires between each test panel. After the configuration it was necessary make the tests. We used secondary protection tester CMC 256plus. After the tests was analysis fault´s records and has been verified the accuracy of the proposed logical busbar protection.
