Method and device for monitoring GOOSE messages of digital substation

The invention discloses a method and device for monitoring GOOSE messages of a digital substation. The method includes the steps that after the GOOSE messages are acquired and analyzed, target MAC addresses are extracted from analysis results of the GOOSE messages and the GOOSE messages are classified into corresponding data queues according to the target MAC addresses; the GOOSE messages are correspondingly stored and marked according to characteristic values in corresponding data queues; the GOOSE messages are independently, comprehensively and quickly monitored from the aspects such as whether the GOOSE messages are test signals or not, whether the GOOSE messages are lost or not, whether the GOOSE messages skip or not, whether the GOOSE messages shift normally or not, whether the GOOSE messages are in an inverted sequence or not, whether the GOOSE messages hop or not, whether the GOOSE messages are repeated or not and whether the GOOSE messages indicate intelligent electronic device resetting or not. The method and device for monitoring the GOOSE messages of the digital substation provide data support for dealing with hidden failures and provide preconditions for further analyzing whether relevant intelligent electronic devices in the digital substation operate normally or not.
