Abstract
The present disclosure illustrates a switch device for substation and an error warning method thereof. The switch device accesses and copies a generic object oriented substation event (GOOSE) packet, and when the copied GOOSE packet is determined to trigger an abnormal condition event, the switch device generates and transmits an abnormal condition event confirmation request to an upstream switch device. A warning message is issued when a ready response cannot be received by the switch device from the upstream switch device. Therefore, the technical effect of quickly and accurately finding the switch device triggering the abnormal condition event first to facilitate repair may be achieved.
