Abstract

A switch device and fault warning method suitable for substations. The switch device copies and accesses the general purpose-oriented substation event grouping. When the switch device judges that the general purpose-oriented substation event group triggers an abnormal state event, the switching The switch device generates an abnormal state event confirmation request and transmits it to the corresponding upstream switch device. When the switch device fails to receive a ready response from the upstream switch device, it sends a warning message, so that the initial trigger abnormality can be quickly and accurately known The switch device for status events for technical efficiency in maintenance.

Description

technical field [0001] A switch device and a fault warning method, in particular to a switch device and a fault warning method suitable for substations. Background technique [0002] Generic Object Oriented Substation Events (Generic Object Oriented Substation Events, GOOSE) is the most important communication protocol in IEC 61850 substations, and its protocol defines the control commands between intelligent electronic devices (Intelligent Electronic Devices, IEDs) in substations. [0003] When an abnormality occurs in the system, the supply of power lines in the abnormal area will be stopped to isolate and protect the normal power supply in other areas. Therefore, the correct and immediate action of the general goal-oriented substation event grouping can reduce the affected range when an abnormality occurs. Minimize the loss of money and operation. [0004] When the existing intelligent electronic device cannot normally receive the general purpose-oriented substation even...
