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.

The object of the invention is to have come by following technical solution, described a kind of transformer station on-Line Monitor Device automatic fault diagnosis method, described transformer station's on-Line Monitor Device is primarily of on-Line Monitor Device, the network switch, photoelectric commutator photoelectricity switch and CAC composition, described transformer station's on-Line Monitor Device adopts SNMP, ARP, Ping, Telnet, the technology such as data filtering, realize on-Line Monitor Device network failure, hardware fault, the automatic diagnosis identification of the faults such as data exception, and provide detailed diagnostic analysis report to supply the reparation of repair and maintenance personnel fast failure, described automatic fault diagnosis method specifically comprises:
1) transformer station's on-line monitoring network topology automatic analysis, it utilizes transformer station's on-line monitoring network topology, makes all-network switch, photoelectricity transponder arranges IP and open SNMP function; First CAC utilizes Ping and Arp technology to obtain the IP address of all-network equipment in on-line monitoring networking, utilize the SysObjectID node of snmp protocol can pick all switches, utilize the dot1dBridge node of snmp protocol to analyze other network equipment MAC Address that port each with switch be connected and IP address, thus to construct with CAC be the network tree architecture on summit;
2) power transformation on-Line Monitor Device fault automatic location, when CAC finds that certain on-line monitoring network interrupts, available PING and telnet command access on-Line Monitor Device and switch step by step from the network bottom, and judgement is that trouble spot is at device, switch or photoelectricity transponder;
3) on-line monitoring abnormal data filtering, when described CAC normally can accept online monitoring data, if find that online monitoring data belongs to following several situation, the database or mail to superior system of restoring after filtering being carried out to data:
A) online monitoring data exceeds Practical Project scope, and data quality position is designated as overflow status;
B) online monitoring data rate of change absolute value exceedes threshold value, temporarily retains data; If next group date restoring is normal, then the accidental data retained is abandoned; If next data keep state after sudden change, then will retain data stored in database or mail to superior system;
C) all data of on-Line Monitor Device become 0 suddenly, temporarily retain data; If next group date restoring is normal, then the accidental data retained is abandoned; If next group data are 0 entirely, data quality position is designated as suspicious state, data will be retained stored in database or mail to superior system;
4) power transformation on-Line Monitor Device Analysis on Fault Diagnosis is reported, power transformation on-Line Monitor Device can using above failure diagnosis information as Real-time Alarm; After user receives alarm, the report of on-Line Monitor Device Analysis on Fault Diagnosis can be transferred and carry out judgment means failure condition; The report of on-Line Monitor Device Analysis on Fault Diagnosis comprises the networking state, PORT COM state, abort situation, data mode etc. of device.
It is simple and reliable that the present invention has method, can utilize transformer station's on-line monitoring network topology automatic analysis, fault automatic location; The features such as on-line monitoring abnormal data filtering.
