Description and testing of communication protocols IEC 60870-5-103 and 60870-5-104

This thesis is focused on testing of communication protocols IEC 60870-5-103 and IEC 60870-5-104. Theoretical part of the thesis describes basic principles, services and possibilities of both communication protocols. Practical part of the thesis deals with configuration of the IEC 60870-5-103 communication standard of protective terminal REF630. PCVDEW6 tool was used to test this communication protocol. Next part of the thesis is focused on convertion of the communication standard IEC 61850 to IEC 61870-5-104 using control system COM600. The testing of both communication protocols was carried out in the laboratory of the protection relays on the testing panels at ABB Brno
