| Abstract [eng] |
Eletrical network relay protection and automation laboratory system was made in this final work. The theoretical part examined multifunctional relay design and features. Their discrete and analog signal converters, relay inputs and outputs. Information visualization tools, storage of digital devices and communication with other digital devices. It was chosen for further microprocessor relay siemens siprotec 4 group 7SJ611. Described in its selection and communication connections. To adjust the settings and inputs, output configuration. For practical purposes it was made microcontroller protectors test stand for future engineers get acquainted with the work of such relays and configuration parameters. As well as atypical mode test and analysis. |
