In a first aspect, referring to fig. 1, an embodiment of the present invention discloses a method for studying and judging internal and external alarm information of a substation, including:
s100, acquiring and analyzing the alarm file to obtain fault information, and judging the fault type according to the fault information;
s200, judging whether the fault information is true or false according to the fault type;
s300, if the fault information is true, judging a fault factor of the fault information;
s400, feeding back the fault factors to the terminal equipment.
The method comprises the steps of obtaining an alarm file, analyzing the alarm file to obtain fault information, judging a fault type according to the fault information, and judging whether the fault information is true or not according to the fault type after judging the fault type. If the fault information is true, the fault factor of the fault information is judged, and the fault factor is fed back to the terminal equipment, so that the automatic analysis of the alarm file is realized to extract the fault information, the fault factor of the fault information is obtained, the fault information and the fault factor are not required to be judged manually, the efficiency of fault analysis can be improved, the labor is saved, and the monitoring of the transformer substation is more intelligent.
The method comprises the steps of acquiring alarm files periodically according to a preset acquisition event, acquiring the latest alarm file, analyzing to acquire the latest fault information, and updating the fault information all the time.
In this embodiment, the latest alarm file is read every 1 minute, and then the alarm files of the latest 5 minutes, that is, 5 alarm files are analyzed to periodically update the fault information. And if the current time is 11 points and 25 points, analyzing the alarm files from 11 points and 20 points to 11 points and 25 points to accurately judge the fault information.
In some embodiments, the fault types include: feeder switch tripping, in-station switch tripping, bus voltage loss, and out-of-station switch tripping. Wherein the fault information includes: and judging the fault type to be bus voltage loss according to the current information and the switch tripping information, and judging the fault type to be feeder switch tripping, in-station switch tripping and out-station switch tripping according to the switch tripping information. Therefore, after the fault type is clear through analyzing the fault information, the authenticity of the fault information under a certain fault type can be accurately judged, the fault factor is acquired corresponding to the fault information, whether the current fault information is true or not is accurately judged, and the factor causing the fault is clear, so that a user can conveniently maintain according to the fault information and the fault factor.
In some embodiments, referring to fig. 2, step S100 comprises:
s110, acquiring and analyzing the alarm file to obtain fault information;
s120, identifying fault content in the fault information;
s130, if the fault content contains 'F', the fault type is feeder switch tripping;
s140, if the fault content contains 'L and/or D and/ST', the fault type is tripping of the switch in the station;
s150, if the fault content has the fault lower limit, the fault type is bus voltage loss;
and S160, if the attribute information of the off-site switch exists in the fault content, the fault type is the trip of the off-site switch.
Because the way of judging the authenticity of the fault information by each fault type is different, the fault type needs to be determined first to judge the authenticity of the fault information in the next step. And analyzing the fault information through the alarm file, identifying fault content in the fault information, and judging the fault type according to the fault content. The fault content is filtered to be 'F, L, D, ST, the lower limit of the accident is exceeded', if the fault content does not exist 'F, L, D, ST, the lower limit of the accident is exceeded', the judgment is directly ended, and no fault event exists. Wherein, F represents a feeder outlet switch, L represents an arc suppression coil, D represents a grounding transformer, ST represents a station transformer, and the lower limit of accidents is bus voltage loss, so keywords are extracted from the fault contents. If the keyword of 'F' exists, the fault type is feeder switch tripping, and if the keyword of 'L, D, ST' exists, the fault type is in-station switch tripping; if the keyword of exceeding the lower limit of the accident exists, the fault type is the bus voltage loss; and if the key words of the attribute information of the off-site switch exist, the fault type is the trip of the off-site switch. Therefore, the fault type is judged accurately by extracting whether the fault content has the keyword corresponding to the fault type.
In some embodiments, referring to fig. 3, since the different fault types have different true and false manners for determining the fault information, it is necessary to determine the fault type first and then perform the true and false determination on the fault information. Therefore, when the fault type is feeder switch trip, step S200 includes:
s210, obtaining the feeder line information according to the fault content, judging whether a single line diagram exists in the feeder line information,
s220, if the single line diagram does not exist in the feeder line information, the fault information is false;
s230, if the single line diagram exists in the feeder line information, judging whether the switch state of the feeder line in the single line diagram is the running state;
s240, if the switch state is not the running state, the fault information is false, and the fault information is debugging information;
s250, if the switching state is the running state, judging whether the feeder line has an executing main network maintenance list;
s260, if the feeder line has an executing main network maintenance list, and the current time in the main network maintenance list exceeds the scheduled power restoration time, the fault information is false, and the fault information is debugging information;
and S270, if the main network overhaul list in execution does not exist in the feeder line, and the signal after the accident brake-off of the feeder line occurs has a protection action signal of the feeder line, the fault information is true, and the fault information is the tripping information of the feeder line switch.
When the fault information is judged to be true or false, namely the fault information is judged to be that the feeder switch is tripped because of faults, the feeder switch is tripped due to the influence of several aspects, and if the feeder switch of the transformer substation is in a debugging state, the feeder switch is also tripped, so that the feeder switch is not tripped due to fault factors. Therefore, it is necessary to filter out the true and false judgment of the feeder switch trip caused by debugging or failure of the line corresponding to the feeder switch, so as to accurately judge whether the fault information is true.
Specifically, it is first necessary to determine whether the fault content has a keyword of "accident tripping", and if so, further obtain feeder line information according to the fault content, and if not, it is proved that the feeder line switch has not tripped, and then the next step needs to be executed. After the feeder line information is obtained, whether the feeder line information has a single line diagram corresponding to the feeder line information needs to be judged, if yes, the feeder line is proved to be put into production, and if not, the feeder line is proved not to be put into production. And if the feeder line is not put into production, the fault information is false, and the judgment of the authenticity of the fault information is finished. If the single line diagram proves that the feeder is put into production, whether the switching state of the feeder in the single line diagram is the running state or not is further judged according to the single line diagram, if the switching state of the feeder in the single line diagram is the non-running state, the feeder is proved to be in the debugging state, the fault information is false, and the fault information is not true fault but debugging information. If the switch state of the feeder line in the single line diagram is the running state, whether the feeder line has an executing main network maintenance list is judged according to the feeder line information, if the main network maintenance list exists, a bus to which the feeder line belongs has power failure in the main network maintenance list, and the current time exceeds the scheduled power restoration time, the currently acquired fault information is proved to be false, the fault information is debugging information, and the current feeder line is proved to be in the debugging state. If the feeder line does not have the main network maintenance list in execution, whether fault information after the accident switching-off exists a protection action signal of the feeder line needs to be judged, if the fault information exists the protection action signal of the feeder line, the fault information is true, and the fault information is the tripping of the feeder line switch, so that the tripping of the feeder line switch is accurately judged. The judgment of whether the protection action signal exists is mainly to judge whether a transformer substation where the feeder line is located has protection operation, and whether the action protection signal exists is accurately judged by judging whether keywords of the transformer substation and protection action exist in fault contents and judging whether the time difference between the protection action signal and the accident tripping is less than 10 seconds.
In some embodiments, referring to fig. 4, when the fault type is feeder switch trip, the determining the fault factor of the fault information in step S300 includes:
s310, acquiring a power distribution network power failure list, wherein if the current time is within the preset power failure time range of the power distribution network power failure list, the fault factor of the tripping of the feeder switch is power failure operation.
After the feeder switch is tripped, the fault information is determined to be a fault factor causing the feeder switch to trip, and a preset power failure time range of planned power failure of the power distribution network power failure list is mainly obtained. And if the current time is within the preset power failure time range, the fault factor causing the feeder switch to trip is proved to be power failure operation. And if the current time is not within the preset power failure time range, the feeder switch tripping is proved to be the tripping caused by the feeder switch fault. After the fault factors are obtained and fed back to the terminal equipment, a user can check the fault factors of the tripping of the feeder switch through the terminal equipment so as to take protective measures according to the fault factors, intelligent fault information analysis and fault factor analysis are realized, manpower is saved, and the efficiency and the accuracy of fault factor analysis are improved.
In some embodiments, referring to fig. 5, when the fault type is an in-station switch trip, step S200 includes:
s210', acquiring substation information of the substation according to the fault content, and judging whether the substation is put into production or not according to the substation information;
s220', if the transformer substation corresponding to the transformer substation information does not have production, the fault information is false;
s230', if the transformer substation corresponding to the transformer substation information is put into operation, judging whether the switch state in the main wiring diagram of the transformer substation is the running state or not according to the transformer substation information;
s240', if the switch state in the transformer substation main wiring diagram is not the running state, the fault information is false, and the fault information is debugging information;
and S250', if the switch state in the main wiring diagram of the transformer substation is the running state and a protection action signal exists after the accident tripping, the fault information is true, and the fault information is the trip information of the switch in the substation.
Judging whether a keyword of 'accident tripping' exists in fault content, if so, acquiring substation information of the substation according to the fault content, and judging whether the substation corresponding to the substation information is put into production according to the substation information, wherein whether the substation is put into production is judged, whether a distribution and dispatching ledger is put into production is mainly judged, if not, the situation is that the substation is not put into production, and if so, the situation is that the substation is put into production. If the transformer substation does not have production, the fault information is false, namely no fault information exists. If the transformer substation is put into operation, whether the state in the transformer substation main wiring diagram corresponding to the transformer substation information is an operating state needs to be further judged. If the main wiring diagram of the transformer substation is not in the running state, the current transformer substation is proved to be in the debugging state, so that the fault information is false, and the fault information is in the debugging state. If the state in the main wiring diagram of the transformer substation is the running state and the fault signal after the accident opening has the protection action signal of the in-station switch of the transformer substation, the fault information is true and the fault information is the trip information of the in-station switch. Whether a protection action signal exists is judged mainly through whether keywords of ' transformer substation ' and ' protection action exist in fault contents, and the judgment of the keyword of the ' protection action ' can be used for judging whether the protection action signal exists or not, judging whether the fault information is true or false and judging whether the fault information is false or not.
Referring to fig. 6, after the fault information is judged to be true and is the trip information of the switch in the station, the fault factor needs to be further analyzed. Therefore, for the fault type being the trip of the switch in the station, the fault factor of the fault information in step S300 includes:
and S320, acquiring a power distribution network power failure list, wherein if the current time is within the preset power failure time range of the power distribution network power failure list, the fault factor of the switch trip in the station is power failure operation.
Firstly, acquiring a distribution network power failure list, then identifying a preset power failure time range of the distribution network power failure list, and if the current time is within the preset power failure time range, proving that a fault factor of switch tripping in a station is power failure operation. If the current time is not within the preset power failure time range, the fact that the fault factor of the in-station switch tripping is the tripping caused by the self fault of the in-station switch is proved, the formed fault factor is fed back to the terminal equipment, and a user can check the fault factor of the in-station switch tripping through the fault factor so as to maintain the in-station switch according to the fault factor and ensure the normal operation of the in-station switch.
In some embodiments, referring to fig. 7, if the fault type is bus voltage loss, step S200 includes:
s210', obtaining the current voltage information of the substation bus according to the fault content;
