Testing of the differential protection relays by the tester CMC256+
Machovič, Jakub ; Orságová, Jaroslava (referee) ; Toman, Petr (advisor)
The bachelor`s thesis is focused on the concepting of tests and measurements for the differential protection relays by the tester CMC 256+. At the beginning of the document are elaborated theoretical knowledges of electrical wiring failures and their consequences, which differential protection relays help to prevent. Furthermore, the description of the function of differential protection relays and their splitting by way of comparison and protecting criteria. Theoretical analysis of differential protection relays testing includes a brief description of measurements carried out by conventional laboratory techniques and a detailed description of the measuring by tester CMC 256 + along with an explanation of its functions. The thesis include a description of functions and parameters measured by differential protection relay S-30 of the ZPA Trutnov company. This work is accompanied by a laboratory task concept focusing on comparative tests of S-30 along with a description of the measuring procedure by using CMC 256+. The concept of tasks is based on the options that are available by using the basic operating software Protection package and the acomplished measurements.

Testing of Synchro-check Function of Feeder Protection Terminal
Cekl, Jakub ; Wasserbauer, Vojtěch (referee) ; Orságová, Jaroslava (advisor)
This thesis is oriented on testing of automatic synchronizing with the help of the machine terminal REM 545 by ABB and its synchro-check function by CMC 256+ tester by OMICRON, where network and alternator parameters are simulated. Basic principles of phasing and phasing conditions are briefly mentioned. Creation of configuration, tester preparing and test execution are described in following chapters. Test of real use is suggested at the end.

Testing of the IEC 61850 relay communication
Bolgár, Robert ; Topolánek, David (referee) ; Toman, Petr (advisor)
Goal of this thesis is practical use of standard IEC 61850, which deals with communication between devices in substation. The main idea is create a model for testing communication between relays with testing device CMC 256+ from OMICRON company and his software equipment „IEDScout“, „GOOSE Configuration“ and „QuickCMC“.
