System for testing roundtrip time between intelligent electronic devices

摘要

In one embodiment, a system (100) is provided including: a first intelligent electronic device (IED) (110A); and a second IED (110B) in communication with the first IED (110A), wherein each IED (110A, 110B) comprises: a transmitter (40) for transmitting a Generic Object Oriented Substation Event (GOOSE) message to another IED at a first timestamp; a receiver (50) for receiving the GOOSE message from the another IED at a second timestamp; a calculator (60) for calculating a roundtrip time based on the first timestamp and the second timestamp; and a determinator (70) for determining if the roundtrip time is within a specified roundtrip time.
