5 Requirements for Standard in SA Interoperability The ability for IED s from one or several manufacturer to exchange information and use the information for the their own functions. Free configuration The standard shall support different philosophies and allow a free allocation of functions e.g. it must work equally well for centralized (RTU like) or decentralized (IED base) systems. Long term stability The standard shall be future proof, i.e. it must be able to follow the progress in communication technology as well as evolving system requirements. July 1, 2013 Slide 5

13 Application examples Circuit-breaker failure protection OK, I hear you! I ll open my Breaker X REF615 IED B X REF615 IED A GOOSE message IED B (outgoing feeder) detects a fault, issues an opening command to its breaker and starts the breaker failure protection The breaker of the outgoing feeder fails to open and after a set time delay the breakerfailure protection in IED B sends a BFP trip command to IED A as a GOOSE message After receiving the GOOSE message IED A issues an opening command to the incoming feeder breaker and the fault is cleared My Breaker is not opening!
