Abstract

The invention relates to a substation online monitoring device fault automatic diagnosis method. The method includes the following steps that:1) substation online monitoring network topology automatic analysis: all network switches and photoelectric repeaters are made to set IPs and enable SNMP functions through utilizing substation online monitoring network topology; 2) substation online monitoring device fault automatic location: when a CAC finds that a certain online monitoring network is interrupted, the CAC can access online monitoring devices and the switches level by level from the bottommost layer of a network through utilizing PING and Telnet instructions, and judge whether a fault point is located on the devices, the switches or the photoelectric repeaters; 3) online monitoring abnormal data filtering: when the CAC can normally receive online monitoring data, and find that the online monitoring data belongs to following several cases, the CAC filters the data and then stores the same in a database or sends to a high-level system: and 4) substation online monitoring device fault diagnostic analysis reporting: a substation on-line monitoring device adopts the above fault diagnostic information as real-time alarm, and the user calls an analysis report to judge device fault situations after receiving the alarm.

Description

technical field [0001] The invention relates to a fault automatic diagnosis method for an on-line monitoring device of a substation, and belongs to the technical field of on-line monitoring and fault diagnosis of a substation. Background technique [0002] In recent years, a large number of on-line monitoring devices in substations have been installed and applied, laying a solid foundation for the informatization construction of smart substations. However, the quality of each manufacturer is uneven, and the online monitoring device presents the characteristics of high failure rate and unstable data. Due to the many levels of the online monitoring network of the entire substation, accurate analysis of the location of the fault and timely maintenance is a problem that needs to be solved in the application of online monitoring. In view of the instability of the data of the online monitoring device, the simple data filter can filter out most of the mutation data. Contents of ...
