Specific embodiment
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clearly defining.
Refer to Fig. 1, the embodiment of the present invention includes：
A kind of power communication anomalous event filter method, comprises the following steps：
1st, after message accounting analytical equipment grabs basic data, record preserves original message.
2nd, the message getting in step 1, using following intelligent identification Method, anomalous event, recognition methodss are analyzed
Including：Single-point information continuous monitoring, up-downgoing message analysis, the same information point of primary channel monitoring rate relatively, different information point
Correlation comparison, by these intelligent identification Methods, filter out different types of anomalous event.
(1) single-point information continuous monitoring method is made comparisons to the real-time data record stacking that each is put, and determines remote signalling and trembles
Dynamic event, remote measurement transition event, remote measurement unchanged event for a long time.Telesignalling dithering event, remote measurement transition thing are described separately below
The filter method of part, remote measurement unchanged event for a long time：
Telesignalling dithering event filtering method：Under normal circumstances, remote signalling amount will not have multiple displacement at short notice or connect
Continue displacement, such as in setting time window, same remote signalling point repeatedly conjugates or continuously conjugates, and is judged as " telesignalling dithering thing
Part ", concrete grammar is in setting time window (as 10 seconds), calculates the remote signalling change frequency in setting time section, such as changes
Number of times exceeds setting value and is extremely；
Remote measurement transition event filtering method：Most of remote measurement amount is under normal circumstances all without quick change moment
Change, this is the physical characteristics decision under being run by its corresponding physical quantity is normal, such as the load in certain region, electrical network frequency
Rate, electric current, voltage etc., when stable telemetry curve plays peak value suddenly, are judged as " remote measurement transition event ", specially exist
A suitable saltus step amount limit value is set, the currency using remote measurement amount deducts previous value, if both differences in filter method
Absolute value be transition more than saltus step amount limit value；
Remote measurement unchanged event filtering method for a long time：In electrical network, many physical quantitys all have the characteristic of real-time update, this
A little physical quantitys can change over time and change, it is abnormal that these remote measurement amounts keep not changing for a long time, frequently not
The embodiment of live time of day.In filter method, during to each telemetry station continuous monitoring, length in same telemetry station
Time does not change, and is judged to " remote measurement unchanged event for a long time ".
(2) up-downgoing message analysis method is analyzed by the descending implementing result to upper line command, filters out descending
Command timeout event, down order are not carried out event.Described down order time out event, down order are not carried out the filtration of event
Method is：
Down order time out event filter method：Set a limiting time, if finding in limiting time that main website issues
Order gives recording-related information and time, without due response frame in limiting time, then for " down order surpasses
When "；
Down order is not carried out event filtering method：Set a limiting time, main website transmitting order to lower levels in limiting time
Give recording-related information and time, receive the reply of positive response, but the return of no respective action, then it is " down order
It is not carried out ".
(3) value of main channel and standby passage is entered by the monitoring relative method of the same information point of primary channel to same information point
Row intersection compares, and determines the asynchronous event of remote measurement, the asynchronous event of remote signalling.Wherein, the asynchronous event of remote measurement, remote signalling are asynchronous
The filter method of event is：
The asynchronous event filtering method of remote measurement：Record the same telemetry intelligence (TELINT) point of active and standby passage respectively, and set one
Time window, such as 5 minutes, resets a limit value, the active and standby dual pathways that will record in window at the same time
Value intersect compare, the phase difference that the value of the same telemetry intelligence (TELINT) point of bilateral trace record relatively obtains exceedes limit value, judge
Go out " the asynchronous event of remote measurement "；For example, define " phase difference=(| the value of the identical telemetry station of the passage first changing-rear
The value of the identical telemetry station of the passage of changing | the value of the identical telemetry station of the passage that ÷ first changes) ", limit value defines
For 0.001.As 00:00:001～00:05:When 001, telemetry station 1 changes value for 220.05 in main channel, with
Telemetry station 1 occurs in time window and changes value for 220.06 in standby passage, now calculating phase difference is | 220.05-
220.06 | ÷ 220.05=0.000045, less than limit value 0.001, it is judged to that remote measurement is synchronous；As 00:00:001～00:
05:When 001, telemetry station 1 changes value for 220.05 in main channel, leads to standby with telemetry station 1 in time window
Road changes value for 220.10, and now calculating phase difference is | 220.05-220.10 | ÷ 220.05=0.0043, more than restriction
Value 0.001, is judged to that remote measurement is asynchronous；As 00:00:001～00:05:When 001, telemetry station 1 occurs in main channel
Changing value is 220.05, changes value in standby passage with telemetry station 1 in time window, is now directly judged to remote measurement
Asynchronous.
The asynchronous event filtering method of remote signalling：Record the same remote signalling information point of active and standby passage respectively, with this remote signalling point
Changing value is as the trigger point time each time, this all changes value under journal, and sets a time interval, and often completely one
The active and standby twin-channel value intersection recorded is compared by individual time interval, if value is inconsistent, is judged to " the asynchronous thing of remote signalling
Part ".For example, defining a time window is 1 minute, e.g., 00:00:001～00:01:When 001, in time point 00:
00:001 remote signalling point 1 changes value for conjunction value in main channel, now, 00:00:001 trigger point calculating as main channel, touches
Send out and check standby passage 00:00:001～00:01:The value of remote signalling point 1 occurs in 001 time window, if conjunction value does not occur, sentences
It is set to remote signalling point 1 asynchronous.As 00:00:001～00:01:When 001, in time point 00:00:001 remote signalling point 1 exists
Standby passage changes value for conjunction value, now, 00:00:001 as the trigger point for path computation, and triggering checks that main channel exists
00:00:001～00:01:The value of remote signalling point 1 occurs in 001 time window, if conjunction value does not occur, is judged to remote signalling point 1 not
Synchronous.
Because the needs of reliability, there are the dual pathways or the multichannel backup of redundancy in field of power communication many plant stands,
The stipulations of these redundant channels can be identical it is also possible to be different, but the data of transmission is consistent.
3rd, the anomalous event filtering out in step (2) is preferentially pushed to dispatching and monitoring end.
