Successful information, operation information are comprising transhipment row or to turn maintenance and do not include factory, stand or the information of field.
This step specifically: from the same day accident abnormality of dispatching log system extract comprising tripping and do not include be overlapped at
The information of function as an information, extracted from the same day accident abnormality of dispatching log system comprising transhipment row or turn maintenance and
Not comprising factory, stand or the information of field is as operation information.
S3, according to number and affiliated station, obtain the corresponding exception information of each electrical object or operation information as the electricity
The key message of gas object.This step specifically: number and title of the station as electrical object are obtained, then according to name
Claim the key message of the exception information or operation information that obtain each electrical object as the electrical object.
S4, keyword is extracted from key message, and close according to obtaining in preset keyword and event corresponding relationship library
Correlating event of the corresponding event of key information as electrical object；Multiple keys are prestored in keyword and event corresponding relationship library
Word, and it is labeled with corresponding event for each keyword, event is power failure or power transmission.
In this way, the corresponding key message of each electrical object is obtained by title comparison, then from key in present embodiment
The keyword that the state comprising electrical object or operational motion are obtained in information is the conclusion of subsequent electrical object correlating event
Specific reference information is provided, ensure that the reliable of the correlating event of the electrical object finally obtained.
S5, it is directed to each correlating event, obtains the electric parameter of corresponding electrical object, and confirm according to electric parameter and be associated with
Whether event is true, is, then records to correlating event；It is no, then delete the corresponding exception information of the correlating event or operation
Information.
In this way, being further confirmed that, being conducive to according to correlating event of the electric parameter to electrical object in present embodiment
Improve the accurate of the correlating event finally obtained.
S6, according in dispatching log maintenance plan information and exception handling information judge correlating event occurrence cause.This
In step, judgment method specifically includes the following steps:
S60, all electrical objects for being identified with correlating event of statistics are as test object.In this way, by electrical object
Screening, be conducive to improve working efficiency.
Maintenance plan information in S61, acquisition dispatching log, and maintenance plan information is handled, it will be each electrical right
The title of elephant carries out unification.Specifically, by Uniform Name, can avoid drain message in this step, to guarantee to detection pair
Effective statistics of the related information of elephant has guaranteed accurately to sentence correlating event occurrence cause on sufficient information condition
It is disconnected.
Specifically, the unification of unified specially naming method is carried out to the title of electrical object, for example, replacing in this step
Changing all " 1#, 2#, 3# " is " #1, #2, #3 ", and replacement " I, II, III " is " I, II, III ".
S62, judge that test object whether there is the maintenance plan letter in the dispatching log same day according to the title of electrical object
In breath.
It S63, is then to judge whether the remote signalling value variation of disconnecting link meets association on route where test object in dispatching log
The variation tendency of event；Meet, then the correlating event occurrence cause that will test object is labeled as planning；It does not meet, then deleting should
Correlating event.
S64, the maintenance object for being not present in maintenance plan information, then judge that it is according to the title of electrical object
In the no exception handling information for being present in the dispatching log same day.
It S65, is then to judge whether the remote signalling value variation of disconnecting link meets association on route where test object in dispatching log
The variation tendency of event；Meet, then deletes the correlating event；It does not meet, then will test the correlating event occurrence cause mark of object
Note is accident.
S66, for be not present in maintenance plan information and there is no with the maintenance object in exception handling information, then judge
Whether the remote signalling value variation of disconnecting link meets the scheduling actions of corresponding correlating event on route where test object in dispatching log,
It is that then will test the correlating event occurrence cause of object to be labeled as dispatching；It is no, then delete the correlating event.
In this way, in present embodiment, in conjunction with maintenance plan information and accident abnormality information to the association thing of a test object
Part occurrence cause is judged and is counted, and realizes the automatic retrospect for correlating event occurrence cause each on power grid, and herein
In the process, it realizes accident investigation and correlating event is further confirmed that, to further ensure the automatic of electric network state
What is monitored is accurate and effective.
