Abstract
The invention relates to an intelligent processing method capable of protecting the operation report of the two ends of a circuit in an online management system. The online management system comprises a main station and multiple substations. The method comprises the steps that the substations send a message to the main station; the main station judges whether the message is relevant to the circuit; if the message is relevant to the circuit, the main station judges whether the message is a line fault event in a power grid and generates the two-end operation report if yes, and the process is ended if not; if the message is irrelevant to the circuit, the main station processes the message. By the adoption of the method, fault messages generated by relevant protective recorder devices in transformer substations at the two ends of a fault line can be automatically converted into a complete two-end operation report more accurately and reliably after the power grid line fails.
Description
Technical field
The present invention relates to electrical network field, particularly relate to electric grid secondary equipment monitor and management, specifically refer to a kind of intelligent processing method protecting line double-end action report in online management system.
Background technology
The requirement of State Grid Corporation of China to power network schedule automation level is in recent years more and more higher, and relay protection information is collected online and is also able to fast development with monitoring thereupon.Relaying protection online management system mainly based on protective relaying device action behavior information concentrated collection during electric network fault, teletransmission and finish message, analysis, is made up of substation and main website two parts.Collection and the teletransmission of information are responsible in substation, and main website is responsible for the unified of information and arranges and analyze, for professional's judge and process power grid accident provide decision support.
Protection information on-line operation and management system are based on the collection of protection information, arrangement and analyze, and can see accurate, complete action report fast after user expects electric network fault most at main website end.Because prior art is too desirable for secondary device action report method for sorting after fault, cause often occurring information leak return, mistake returns and the problem such as maintainability difference, expected result cannot be obtained in actual applications, be mainly manifested in the following aspects:
1, protect crucial trip event by manual sort, workload is large, not easy care;
Artificially event information is classified; a protective device is by 100 case points; a transformer station is by 50 protective devices; net is economized and is adjusted main website generally by access 200 substations; then main website end total event is counted as 100*50*200=1000000 bar; medium scale main website the common event is counted and is all reached 1,000,000; if these information all carry out information classification artificially; workload is very large; follow-up continuous protection reorganization and expansion work in addition; workload impersonal force can be, and actual motion effect does not reach expection.
2, cause information in report to omit problem because on-the-spot secondary device clock is inconsistent
With the time of Article 1 critical event for the information of benchmark to different device is filed, require that the whole network protection and oscillograph equipment clock must be highly consistent; But in fact; because there are each side's reasons such as early having late, device self time adjustment function defect and management protection and the oscillograph device time of putting into operation in transformer station; cause secondary device in each transformer station pair time very inaccurate; even if the distinct device in same transformer station differs several hours, even the phenomenon such as several years is very general, and this is general knowledge well known in the art.Protection in transformer station is as the main operational outfit of protection power grid security, and operate when generally all forbidding that external system carries out soft pair to it in operating standard, unification is upgraded to all protective devices or transformed, very unrealistic again; Therefore from existing situation, in transformer station, the clock of running protection device is difficult to be consistent, when protecting inaccurate clock, then with the temporal information of equipment for foundation, the filing bag of formation will inevitably occur that information is omitted.
3, leak due to distinct device, different rate of information throughput difference and the information that causes return, mistake returns problem
Protective device information transmission to the process of main website is: protection-> substation-> main website; protection producer, type, the information category of transmission and substation producer is related to all different in this; grid collapses in a flash; the amount of information produced is very large; network storm and each implementation and technological means uneven, the speed of final collection information is difficult to consistent.The time that prior art receives Article 1 critical event with main website starts timing, the relevant information received in follow-up X second is included into a fault bag, X receives the information relevant to this fault after second again, then report cannot be included into, X arranges too short, occurs information dropout, arranges long, then twice shorter for interval continuous fault may be included into same report, finally cause leakage to be returned, mistake returns phenomenon.
4, the report generated is too many, and electrical network true fault bag is submerged wherein, cannot correct identification problem
Power grid construction and reorganization and expansion frequent; each transformer station need carry out a lot of dosage test to all kinds of reorganization and expansion protective device every day; after dosage, in protection, the data sent also comprise crucial trip event, and whether most of protective device cannot identify during carry information be in a transport protocol test data.Existing relevant filing way, automatically Trouble Report can be generated equally after main website end receives these Test Information every day, test data and true fault data cannot be identified, cause the test data fault bag that there is a large amount of non-genuine accident in main website end Trouble Report list, and the frequency that electrical network true fault occurs is very low, and (a general area occurs several times for 1 year, maximum tens times), after operation a period of time like this, true accident bag by a large amount of " rubbish Trouble Report " flood, subsequent analysis application very inconvenience.
5, line fault ranging information disappearance or range measurement inaccurate, affect fault fast positioning and recovery.
6, need special messenger's screen of staring on duty to check, do not support that intelligent terminal is applied.

Embodiment
In order to more clearly describe technology contents of the present invention, conduct further description below in conjunction with specific embodiment.
After Guangdong power system, the relevant protection device of circuit two ends transformer station understands action simultaneously and record trouble process.After present invention can be implemented in Guangdong power system accurately, the automatic both-end action report fault message that secondary device relevant in the transformer station of faulty line two ends produces being carried out automatic archiving, form information completely reliably; and be pushed to multiple terminal (i.e. display device of the present invention) in the very first time; professional is facilitated to analyze two ends protection act situation, check; pass judgment on both sides protection act behavior correctness and quick diagnosis fault, recover electrical network and normally run.
Online management system is made up of substation and main website.The sample and transform of information is responsible in substation, main website is responsible for receiving each substation information and comprehensively carries out arranging and analyze, form comparatively perfect, reliable both-end action report, and the very first time is pushed to multiple terminal (i.e. display device of the present invention).
In addition, display device of the present invention is not limited only to display, and refers to and a kind ofly can show or point out user's both-end equipment that action report has generated by the both-end action report generated in the present invention.
Referring to shown in Fig. 1, is the flow chart of steps of the intelligent processing method of line double-end action report in protection online management system of the present invention.
Described method comprises the following steps:
(1) substation described in sends information to described main website;
(2) whether the information described in the main station judging described in is relevant with circuit;
(3) if described information is relevant with circuit, then whether the described information described in main station judging is the line fault event in electrical network;
(4) if described information is the line fault event in electrical network, then described main website generates both-end action report;
(5) if described information is not the line fault event in electrical network, then terminate and exit;
(6) if described information and circuit have nothing to do, then main website processes for this information.
Described step (1) is specially:
Described substation sends the information comprising device information time of origin in electrical network, substation time of reception, event description, device numbering and device model to described main website.
Wherein, for the timing differential solving different protective device in transformer station is comparatively large, the inaccurate problem of information filing, the present invention introduces dual-time source way, a temporal information carried when being and sending data after protective device action itself, i.e. device information time of origin; Another is substation receives information time from protective device, i.e. substation time of reception.
Transmission protocol between substation and main website, when making information from substation Shang Song main website, supports the time of transmission substation itself.Substation from every bar event that protective device and oscillograph receive all with device information time of origin, after substation receives, prime information basis increases the timestamp information of substation itself, namely substation receives the time of this information, and then by information by the stipulations of expansion deliver to main website, the information increasing its temporal is preserved by substation on the spot simultaneously, wherein, it is in order to information backup that information is preserved by substation, when in main website during this information dropout, this information of preserving in substation makes user still can view, in addition, in a preferred embodiment, the information received is stored to database or high in the clouds by described substation or main website, safer to make information preserve.
In addition, main website needs to judge that whether the information received is relevant with circuit, if had nothing to do with circuit, then described main website processes this information according in main website to the processing mode of this information.
Refer to shown in Fig. 2, after main website receives every bar information from each substation, first resolving information, and according to device model and some table information thereof, obtain event description corresponding to this information, device numbering, device model, device information time of origin, substation time of reception.Described main website generates both-end action report, specifically comprises the following steps:
(4.1) whether the filing business of the circuit that the main station judging described in is corresponding with this line fault event exists;
Wherein, according to the device numbering in information and the topological relation (namely step (0-1)) hereinafter set up; obtain the circuit number that it is protected; and then whether report in internal memory arranges the business of searching this circuit number in service lists (i.e. both-end action report of the present invention) and exists; if do not exist; then carry out the latest report bag generating process of step (4.2), otherwise the dual-time source of carrying out step (4.6) judges process.
(4.2) if the filing business of the circuit corresponding with this line fault event does not exist, then whether described this circuit of main station judging exists the trip time;
(4.3) if this circuit exists trip event, then new report bag is generated;
Wherein, major key is generated by " device model _ event description " form; search during the device model set up in internal memory and event description MAP show; if it is true for returning results; then under this equipment institute protection circuit numbered node, generate the latest report node that is title with present event substation time of reception; add this device node in latest report bag, add this information again under device node, otherwise end process.To be reported in internal memory storage node structure as shown in Figure 3.
(4.4) if this circuit does not exist trip event, then step (4.1) is continued;
(4.5) if the filing business of the circuit corresponding with line fault event exists, then whether described main station judging exists the report bag corresponding with this line fault event;
Wherein, whether described main station judging exists the report bag corresponding with this line fault event, specifically comprises the following steps:
(4.5.1) whether the main station judging described in also exists other report bag;
(4.5.2) if there is no other reports are wrapped, then continue step (4.2);
If (4.5.3) also there is other report bag, whether the substation time of reception of this line fault event of described main station judging is in the threshold time of report bag; Described report bag threshold time is for being greater than the difference of report bag time and the first setting-up time and being less than and reporting bag time and the first setting-up time sum;
If (4.5.4), the substation time of reception of line fault event is in the threshold time of report bag, then whether the device information time of origin of described this line fault event of main station judging is in the threshold time of device information; The threshold time of described device information is greater than the difference of device information time of origin and the second setting-up time and is less than device information time of origin and the second setting-up time sum
If (4.5.5) the device information generation event of this line fault event is in the threshold time of device information, then continue step (4.6);
If (4.5.6) the device information generation event of this line fault event is not in the threshold time of device information; Then continue step (4.5.1);
If (4.5.7) the substation time of reception of line fault event is not in the threshold time of report bag, then continue step (4.7).
According to " substation time of reception " in reception event, traversal search report bag belonging to this event (the substation time of reception of this event the report bag time ± N second within the scope of, wherein N is the first set point); If found, then finding in the device numbered node under report bag belonging to present event, " device information time of origin " in further decision event whether within this deuterzooid device information scope time (comparatively under this device node the device information time of origin of Article 1 event within ± M second, wherein M is the second set point), if in scope, then judge the relevant information of present event as this fault, and under this information is included into this device node; If not in scope, this fault non-is then described, continues already present Next Report bag in traversal internal memory by same way, if traversal terminates, this event is not included in any one report bag yet, then carry out the latest report bag product process of step (4.3).
In addition, the problem of dual-time source mechanism solution is as follows:
Owing to there is cycle soft time adjustment function support in the present invention, basically identical after " the substation time of reception " that ensure that on each substation of synchronization in carry information reaches main website.Substation time of reception ± (N can be arranged N mechanism second, the information transmission time difference of generally causing due to a variety of causes can not more than 30 minutes, therefore generally arrange about 1800 seconds), avoid the larger problem of different secondary equipment time difference in transformer station on the one hand, ensure that the distinct device information be associated in same secondary line fault can be included in same report bag by main website accurately; On the other hand, also efficiently solve because substation is sent from the message delay that dissimilar devices communicating mode difference, different types of information transmission rate speed are distinguished and implementation not first-class reason in different substations causes in prior art, thus the main website end report mistake caused is returned, is leaked the problem of returning.
Device information time of origin ± (M can be arranged M mechanism second; general protective device generation continuous several times tripping operation interval is not less than 20 seconds; therefore generally get 20 seconds); ensure that and the tripping operation information of the same primary fault under same secondary device can be included into accurately in same report bag, efficiently solve may occur in prior art by repeatedly continuously different tripping operation be included into the problem of same report.
(4.6) if there is the report bag corresponding with this line fault event, then by this line fault event synchronization to this report bag;
(4.7) if there is no corresponding with this line fault event report bag, then continue step (4.2).
In addition, refer to shown in Fig. 2, further comprising the steps of after described step (4.3):
(4.3.1) main website described in by this line fault event synchronization to this new report bag;
(4.3.2) whether the cycle that the main station judging described in sends information to display module arrives;
If (4.3.3) send the cycle arrival of information to display module, then described main website generates the new report sent to display module;
If the cycle (4.3.4) to display module transmission information does not arrive, then described main station judging arranges the need of exiting both-end action report;
If (4.3.5) need to exit both-end action report to arrange, then described main website terminates and exits;
If (4.3.6) do not need to exit both-end action report to arrange, then continue step (1).
In addition, refer to shown in Fig. 2, further comprising the steps of after described step (4.6):
(4.3.3) main website described in generates the new report sent to display module.
Wherein, the mode combined with filing automatic continuous after fault is filed when present invention employs fault in time.It is very fast due to protective device event class information being sent, be generally in level second and send, consider that both-end many covers protective device send simultaneously, therefore first after L second (L is traditionally arranged to be 60 seconds) the report bag of ArchivalEvent category information is put in storage fast and is notified interface display, so that operations staff understands the basic situation of fault fast; But now in background memory, the life cycle of this report does not terminate, then continuous wait N second, so as to collect delayed on the information sent.In archiving process subsequently, often increase in this report bag or upgrade an information, backstage all can be put in storage in time and be sent fault bag Notification of Changes to foreground, so that the up-to-date report content of display is refreshed at interface in time.Both ensure that the most newly reported promptness, simultaneously also solved compared with prior art the problem that lag information cannot correctly file.
In addition, refer to shown in Fig. 1, in order to ensure the normal work of system, further comprising the steps of before described step (1):
(0.1) main website described in communicates with described substation;
(0.2) when the main website described in and described substation carry out soft pair.
After electric network fault, user is generally a minute rank to generating the time requirement of Trouble Report, when the mode cycle is to each substation system pair when main website adopts soft message pair in the present invention, guarantees that main station system and the time of substation system reach second extremely consistent.
Further comprising the steps of after described step (6):
(6.1) during soft pair of the main station judging described in, whether the cycle arrives;
(6.2) if soft pair of described main website time the cycle arrive, then continue step (0.2);
(6.3) if soft pair of described main website time the cycle do not arrive, then whether described main station judging exits online management;
(6.4) if exit online management, then terminate and exit;
(6.5) if do not exit online management, then step (0.1) is continued.
Further comprising the steps of before described step (0.1):

(1) during circuit true fault; the relevant protection at general circuit two ends all can produce tripping operation information; and when protection dosage being tested in transformer station; equipment reorganization and expansion is all generally to single device dosage test in station; new website is at most also test the relevant device dosage of circuit one end when building, therefore whether available line two ends relevant device all produces tripping operation information as one of foundation judging whether true fault.
(2) situation of part relevant device information Bu Shangsong main website may also be there is when substation system exception or with equipment component communication abnormality, for avoiding this kind of situation to cause main website to judge by accident, special introducing the second basis for estimation.During circuit true fault, not only protection can produce tripping operation information, generally also changes along with circuit-breaker status; And when carrying out dosage test to protective device in transformer station, although protection produces in tripping operation information and send, its circuit-breaker status be associated can not change; Therefore circuit-breaker status can be adopted as another foundation judging to protect whether truly tripping operation.Circuit breaker real-time status and displacement information data are collected mainly through EMS system; protection information management system does not gather circuit-breaker status information; therefore the present invention takes to carry out communication interface mode with EMS system obtains circuit-breaker status; namely after often generating a latest report bag in internal memory filing business; the circuit breaker numbering that this line fault is associated is obtained according to topological relation; then the instant state displacement information obtaining corresponding circuit breaker from EMS system, and then judge whether true tripping operation.
After being judged by above-mentioned two kinds of modes, if truly tripped, then this fault bag is designated true electric network fault bag; Otherwise be designated test data fault bag, and basis for estimation is added in report.
Further comprising the steps of after described step (4):
(4.a) main website described in receives the data message that EMS module gathers;
(4.b) data message that described EMS module gathers is synchronized in both-end action report by the main website described in, and judges whether there is real line fault in electrical network;
If (4.c) there is real line fault in electrical network, then described main website obtains the ranging information of this real line fault further; Otherwise continue step (4.e);
(4.d) main website described in notifies that user's both-end action report generates;
(4.e) described both-end action report stores and shows in display module classification by the main website described in.
In online management system of the present invention line double-end action report intelligent processing method in increase fault localization information accurately in both-end action report, in prior art, the acquisition of line fault ranging information is generally by two kinds of approach: 1. claimed or oscillograph device automatically on give; 2 zero main website ends carry out analytical calculation according to both-end recorded wave file.Because substation field relates to the protective device put into operation various years, comparatively early period do not support send range finding, even if to send ranging information on supporting, result is also single end distance measurement result, and error is larger.If calculated by main website end, not only relate to the work of a large amount of line parameter circuit value configuring maintenance, simultaneously higher to the clock synchronization requirement of two ends generation recorded wave file, the accuracy of parameter and algorithm etc. all can affect the precision of final result.Undesirable through practical application effect, therefore above-mentioned two kinds of modes all do not possess practicality very much.
Small echo ranging system is all the time as the Main Means calculating both-end distance measuring, and range measurement is accurate and precision is high.To adopt directly in the present invention and mode that small echo ranging system interface obtains range measurement is carried out.Specific practice is: using the substation of small echo distance measurement Master station system as protection information online management system; connect and synchrolock model with small echo ranging system; on the one hand can the cycle by soft message mode to small echo ranging system pair time; guarantee the clock of native system and small echo ranging system second level consistent; the communications status of native system and small echo ranging system when can supervise in real time on the other hand, so that abnormal rear timely recovery.After main website end often generates one " true fault report ", according to the numbering of faulty line immediately to this circuit number of small echo ranging system request at that time moment ± K second in range measurement information, if got, range measurement is included into report, otherwise every ten seconds obtain once, support circulation W time, until obtain range measurement.
Namely the manner avoids a large amount of repetition modeling of identical services, configuration effort, also ensure that the required precision of range measurement simultaneously, and practical application effect is good, and comparatively prior art greatly promotes in construction difficulty, practicality, accuracy and economy etc.Described main website obtains the ranging information of this real line fault further, comprises the following steps:
(4.c.1) main website described in obtains the data of small echo range finder module;
(4.c.2) main website described in is by both-end action report extremely described for the data syn-chronization of the little broken range finder module got.
Described main website notifies that user's both-end action report generates, is specially:
By the mode of note or mail, described main website notifies that user's both-end action report generates.
(1) report stores and shows and all presses " true electric network fault bag " and " test data fault bag " classification process, both the demand of consulting true fault bag had fast been solved, also meet user whether correct by the analysis of test data fault bag, judgment device optimum configurations, put into operation in order to avoid delay equipment on schedule.
(2) there is the basis for estimation of report classification in each report, substantially increase the perfection and practicability of action report.
(3) only to " the true electric network fault bag " that generate, support that IMU crosses note and the fault profile information very first time is sent to relevant designated person by mail two kinds of modes, even if on duty without special messenger, also the very first time can understand grid fault conditions, substantially increase compared with prior art the promptness that related personnel understands information.
In addition, referring to shown in Fig. 4, is the arrangement flow chart of steps of volume both-end action report of the present invention.In online management system of the present invention line double-end action report intelligent processing method in can upgrade each both-end action report in main website internal memory, further comprising the steps of after described step (4.e):
(4.e.1) main website described in obtains an existing both-end action report;
(4.e.2) whether the life cycle of this both-end action report of the main station judging described in arrives;
