Problems solved by technology

[0004] In the same-source dual network, when the sending source or one of the communication networks is abnormal, it is easy to cause abnormal messages in the GOOSE data received by the receiver. The current processing method is to manually monitor the abnormal messages and perform Troubleshooting and processing, however, the manual monitoring method has the problems of low efficiency and long processing time
[0005] Therefore, the current GOOSE packet anomaly monitoring technology has the problem of long processing time

Abstract

This application relates to a GOOSE message abnormality monitoring method. The method includes: obtaining the ST field and the SQ field in the received GOOSE message; if the ST field is consistent with the ST field of the previous frame, and the SQ field is consistent with the SQ field of the previous frame, Then generate a first abnormal signal; if the ST field is inconsistent with the shifted ST field of the current frame, generate a second abnormal signal; when detecting the first abnormal signal or the second abnormal signal, generate GOOSE A message abnormal signal; generating a GOOSE message abnormal alarm according to the GOOSE message abnormal signal. By adopting the method, the abnormal situation of the GOOSE message can be quickly monitored, and the processing time of the abnormal monitoring of the same-source dual-network of GOOSE can be shortened.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a method for monitoring abnormality of GOOSE messages. Background technique [0002] GOOSE (Generic Object Oriented Substation Event, Generic Object Oriented Substation Event) is a fast message transmission mechanism in the IEC61850 standard, used to transmit important real-time signals between IEDs (Intelligent Electronic Devices, intelligent power monitoring devices) in substations . In various automatic protection devices in smart substations, it provides basic data for functional modules such as protection logic calculation of primary equipment, information collection and information transmission of equipment in the station. [0003] In terms of reliability design of smart substations, dual redundant design methods are often used, for example, dual AD redundant sampling is used for analog sampling of primary equipment, and dual CPU processing is used for co...
