The equipment alarm information and the equipment operation data input into the expert database reasoning algorithm model may be equipment alarm information and equipment operation data of the same equipment, or equipment alarm information and equipment operation data of a plurality of different equipments, and if the input equipment alarm information and the equipment operation data are data of a plurality of equipments, whether a causal relationship exists between the generation of the alarm information of the equipments can be analyzed according to the concurrent conditions of the alarm information of the equipments (for example, when a fault a occurs, a fault B also occurs at the same time).
And 103, associating and combining the equipment alarm information with the same alarm reason according to the alarm reason.
It should be noted that, when a fault event occurs, multiple pieces of equipment alarm information are often generated, and when the alarm reasons output by the expert library inference algorithm model are used, the equipment alarm information belonging to the same alarm reason is associated and combined.

The above is a detailed description of a first embodiment of the intelligent substation alarm processing method provided by the present application, and the following is a detailed description of a second embodiment of the intelligent substation alarm processing method provided by the present application.
Referring to fig. 2 and 4, a second embodiment of the present application provides an intelligent substation alarm processing method, including:
It should be noted that, in step 201 and step 202 of this embodiment, an expert library inference algorithm model is established through the collected historical alarm events of the intelligent substation and the operation data of the alarm device, and the established model can be used for performing alarm reason analysis in subsequent steps.
And step 203, receiving equipment alarm information and equipment operation data uploaded by the intelligent substation.
It should be noted that, in the embodiment, the device operation data is specifically acquired in real time by a panoramic signal gateway deployed in an intelligent substation, and information interaction data of a station control layer and a bay layer is acquired by recording a message of a mirror interface of a station control layer switch; and acquiring auxiliary system information through an IEC61850MMS or DL476 transmission protocol, and uploading the equipment alarm information and the acquired equipment operation data when an alarm event occurs.

It should be noted that the filtered device alarm information is not input into the expert base inference algorithm model of this embodiment for operation, and may be stored in a preset buffer or directly reported to the scheduling end of the background.
Specifically, the following example can be referred to for the processing manner adopted for different filtering information:
(1) companion signal processing
In the process of switch operation, due to the fact that the contact shakes, the control loop is reported to be broken, the spring is reported to be not stored with energy due to insufficient time delay, and related signals such as device alarm and the like are generated by devices of individual types. The program places these accompanying signals in a buffer area, and if the corresponding reset item is received within a certain time delay, the signal will not be reported. Otherwise, if there is no reset item in the delay, the signal is reported after the delay is finished. If the time delay of 'spring non-stored energy' is 20s, 'control circuit is broken' and 'device alarm' is 2 s.
(2) Dither signal processing
For frequent jittering signals caused by poor insulation of the auxiliary contact, the signals are generally single signals, such as frequent deflection of a disconnecting link and frequent alarm resetting of the device. Judging whether the signals are jitter signals or not by counting the action times of the signals in a certain period, directly alarming and displaying that the signals are jitter signals after the signals are the jitter signals, and displaying and sending judgment results of the jitter signals.
(3) Non-operational state information filtering
The intelligent warning system of the transformer substation filters information of non-operational state equipment such as cold standby equipment, maintenance equipment and the like. Wherein cold reserve interval state passes through equipment state judgement, and the maintenance state passes through topological information such as switch, earthing switch position to and KK handle position comprehensive judgement.
After the filtered and screened device alarm information and device operation data of the intelligent substation are obtained, the device alarm information reflecting the device alarm condition and the device operation data reflecting the operation state of the device during alarm are input into a preset expert database inference algorithm model, and corresponding alarm reasons are obtained by matching historical alarm event samples in the expert database and trained inference algorithm rules.
The equipment alarm information and the equipment operation data input into the expert database reasoning algorithm model may be equipment alarm information and equipment operation data of the same equipment, or equipment alarm information and equipment operation data of a plurality of different equipments, and if the input equipment alarm information and the equipment operation data are data of a plurality of equipments, whether a causal relationship exists between the generation of the alarm information of the equipments can be analyzed according to the concurrent conditions of the alarm information of the equipments (for example, when a fault a occurs, a fault B also occurs at the same time).
And step 206, associating and combining the equipment alarm information with the same alarm reason according to the alarm reason.
It should be noted that, when a fault event occurs, multiple pieces of equipment alarm information are often generated, and when the alarm reasons output by the expert library inference algorithm model are used, the equipment alarm information belonging to the same alarm reason is associated and combined.
