Abstract
An automatic screening method for fault recording documents in a grid fault information system comprises the following steps: reading fault recorder information, judging whether a grid goes wrong or not, judging analog quantity sudden change data, judging switching value tripping data, marking the data as an internal fault, carrying out fault location, marking the located fault as an external fault, and the like. The automatic screening method has the advantages that data recorded by a fault recorder can be screened, classified and stored automatically; only the part related to fault equipment is reserved to facilitate targeted analysis of fault data for related technical personnel.
Description
Technical field
The invention belongs to electric network fault information system technical field, particularly relate to the auto-screening method of failure wave-recording file in a kind of electric network fault information system.
Background technology
Along with the development of computing machine and mechanics of communication, the use of fault oscillograph in electric grid secondary equipment is very general.In the time that electric system is broken down or be disturbed, fault oscillograph can record a large amount of data and information.Be the precious troubles inside the sample space data of value and only have a little in the middle of these information, troubles inside the sample space data can be used for the purposes such as localization of fault.How these are worth to precious troubles inside the sample space recorder data in the marine salvaging of data of fault oscillograph out, carry out emphasis mark, become those skilled in the art's problem anxious to be resolved.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide the auto-screening method of failure wave-recording file in a kind of electric network fault information system.
In order to achieve the above object, in electric network fault information system provided by the invention, the auto-screening method of failure wave-recording file comprises the following step of carrying out in order:
Step 1) S01 stage of reading oscillograph information: the information in read failure oscillograph, then enters next step;
Step 2) judge whether S02 stage of breaking down: according to the information that the S01 stage obtains, judge current whether breaking down; If judged result is "Yes", enters next step S03 stage, otherwise finish this operation;
Step 3) judge S03 stage of analog quantity accidental data: judge in the information that the S01 stage obtains whether comprise analog quantity accidental data, if judged result is "Yes", enter next step S04 stage, otherwise next step enters the S07 stage;
Step 4) judge S04 stage of switching value tripping operation data: judge and in the information that the S01 stage obtains, whether comprise the switching value data that trip, if judged result is "Yes", enter next step S05 stage, otherwise next step enters the S07 stage;
Step 5) be labeled as S05 stage of troubles inside the sample space: be troubles inside the sample space information by this information labeling, then enter next step S06 stage;
Step 6) carry out S06 stage of localization of fault: carry out localization of fault according to the troubles inside the sample space information obtaining, then finish this operation;
Step 7) be labeled as S07 stage of external area error: be external area error information by this information labeling, then finish this operation.
In step 3) in, described analog data comprises voltage U and electric current I.
The implementation result of the auto-screening method of failure wave-recording file in electric network fault information system provided by the invention: the data that can automatically include the fault oscillograph storage of screening, classify, only retain the part relevant with faulty equipment, therefore facilitate person skilled to carry out specific aim analysis to fault data.
Brief description of the drawings
Fig. 1 is the process flow diagram of the auto-screening method of failure wave-recording file in electric network fault information system provided by the invention.
Fig. 2 is fault oscillograph line attachment protection figure.
Embodiment
Below in conjunction with the drawings and specific embodiments, the auto-screening method of failure wave-recording file in electric network fault information system provided by the invention is elaborated.
As shown in Figure 1, in electric network fault information system provided by the invention, the auto-screening method of failure wave-recording file comprises the following step of carrying out in order:
Step 1) S01 stage of reading oscillograph information: the information in read failure oscillograph, then enters next step;
Step 2) judge whether S02 stage of breaking down: according to the information that the S01 stage obtains, judge current whether breaking down; If judged result is "Yes", enters next step S03 stage, otherwise finish this operation;
Step 3) judge S03 stage of analog quantity accidental data: judge in the information that the S01 stage obtains whether comprise analog quantity accidental data, if judged result is "Yes", enter next step S04 stage, otherwise next step enters the S07 stage;
Step 4) judge S04 stage of switching value tripping operation data: judge and in the information that the S01 stage obtains, whether comprise the switching value data that trip, if judged result is "Yes", enter next step S05 stage, otherwise next step enters the S07 stage;
Step 5) be labeled as S05 stage of troubles inside the sample space: be troubles inside the sample space information by this information labeling, then enter next step S06 stage;
Step 6) carry out S06 stage of localization of fault: carry out localization of fault according to the troubles inside the sample space information obtaining, then finish this operation;
Step 7) be labeled as S07 stage of external area error: be external area error information by this information labeling, then finish this operation.
In the S01 stage, information in described oscillograph comprises analog data and switching value data, and wherein analog data comprises voltage U, electric current I, high frequency GP, and its medium-high frequency GP is just as Real-time Collection amount, and do not judge still voltage U and the electric current I of main judgement.
Fig. 2 has further explained the difference of troubles inside the sample space and external area error.Such as 115 line faults, fault oscillograph one and fault oscillograph two all can have the variation of analog quantity voltage U, electric current I, change, and fault oscillograph two have the switching value of the trip protection of 115 lines to change but fault oscillograph one does not have switching value.So the fault of 115 lines is external area error to fault oscillograph one, are troubles inside the sample spaces to fault oscillograph two.
In electric network fault information system provided by the invention, the auto-screening method object of failure wave-recording file is a large amount of data and the information of fault oscillograph record to carry out automatic screening, out carry out emphasis mark by being worth precious troubles inside the sample space data screening, carry out the purposes such as localization of fault.In the time containing switching value tripping operation data and analog quantity accidental data in the oscillograph data that receive in same primary fault, be labeled as troubles inside the sample space; When data trip when containing analog quantity accidental data in the oscillograph data that receive in same primary fault without switching value, be labeled as external area error.
It is emphasized that; embodiment of the present invention is illustrative; instead of determinate; therefore this example comprises and is not limited to the embodiment described in embodiment; every other embodiments that drawn according to the technical scheme of this patent by those skilled in the art, belong to the scope that this patent is protected equally.
