Abstract

The invention relates to an exchanger device for a transformer substation and a fault warning method. The exchanger device replicates and accesses a generic object-oriented substation event packet; when the exchanger device determines that the generic object-oriented substation event packet triggers an abnormal state event, the exchanger device generates an abnormal state event confirmation request and transmits the request to a corresponding upstream exchanger device; and when the exchanger device can not receive a ready response from the upstream exchanger device, a warning message is sent out. Therefore, the exchanger device can obtain the initial triggered abnormal state event rapidly and accurately and thus maintenance is carried out conveniently.

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...
