Abstract

This study is an attempt to implement the International Electrotechnical Commission (IEC) - 61850 to protect a transmission line using Generic Object Oriented Substation Events (GOOSE) messaging. IEC 61850 describe rules for integration of protection, control, measurement and monitoring functions within a power system network at the process and station control levels. Earlier envisioned for substation automation, IEC 61850 has shown its potential in eliminating substation wiring, enhanced interoperability between vendors and systems. Thus efforts are now being made to expand it to cover substation to control center and substation to substation automation. In this paper, GE D90 Plus Line Distance Protection relays were used to protect an assumed transmission line scheme through Permissive Overreach Transfer Trip (POTT) communication scheme. Different types of faults were calculated for different locations and tested. GOOSE messages carrying trip signals were transmitted by the relays. The relays operated in the expected tripping zone and picking up right elements thus validating the results. The time delay between tripping the relays at each end of transmission line was found to be ranging between 3 microsecond to 2.9 millisecond.
