Description of drawings
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Fig. 1 is a fault information organization level schematic diagram;
Fig. 2 is a device internal fault associating information;
Fig. 3 is that Trouble Report is integrated between device.
Embodiment
Information process and organize models under the electrical network primary fault in accompanying drawing 1, have been provided, fault message divides three layers to organize in this model: the 1) Trouble Report of device layer, the device here refers to protection, oscillograph etc., finish in the process of " tissue device's Trouble Report " shown in the figure, result comprises to be opened before and after starting fault time, device into information such as displacement, record ripple start-up times, record ripple bulletin for the oscillograph generation, can also recorder data be screened according to the faulty equipment in the bulletin, only keep the part relevant with faulty equipment; 2) fault message of transformer station and wall, " the internal fault associating information of standing " part shown in the figure is finished, and result comprises the device of action under fault time, between-failures and the interval etc.; 3) all information under electric network fault, " electric network fault of tissue " part shown in the figure is finished, and result comprises the device action information of fault parameter and each side.In addition, to the information of sending of transformer station, i.e. the 3rd step of the information processing shown in the figure need in transformer station on the related basis of integrating of plant failure report, be carried out necessary filtration according to certain rule to fault message and select.
When on protection information or record ripple file, delivering to the fault message substation, at first will install the processing module that the information of sending is sent into the substation.In the processing module of substation, set up caching mechanism according to fault message organizational form shown in Figure 1; information element in the buffer memory is by tree type tissue; be divided into primary fault; the interval that primary fault comprises; device report at interval; protection incident in the device report; record ripple file etc.; wherein; the attribute of primary fault comprises ID; describe etc.; plant failure Report Properties under wall and the interval all has the member of an affiliated fault ID; the ID attribute that also has self in the attribute of plant failure report; except General Properties, has only one of affiliated Trouble Report ID in the information element under the device report; the purpose of why doing like this is because wall is a management concept; generally do not need fault to be inquired about from wall; and the plant failure report has embodied the runnability of a table apparatus; often need the action situation of device in inquiry a period of time, the purpose of setting up Trouble Report ID is for the ease of the statistic device Trouble Report.
When new protection information or recorded wave file enter processing module, at first carry out related according to existing device action report in set rule and the buffer memory.If be successfully associated, namely new information belong in the buffer memory certain once move, again according to sending rule information to be carried out sending on the needs whether the judgement of main website on the set information; If related failure; then come action report or the report of record ripple of organization protection according to new information category; judge according to established rule whether this device action report can be related with other action reports in the buffer memory then; if again related failure is then according to No way out being arranged or having fault-free to determine whether that needs set up electric network fault one time.
In message processing module, with the implementation process of device information correlation rule as shown in Figure 2, mainly be divided into and calculate fault zero constantly and set dual mode reset time.Wherein calculate fault zero implementation process constantly in two steps, at first calculate the fault zero of certain device information constantly, determine their whether associations according to whether identical the fault of two information zero constantly then, and the fault time of zero moment of fault as device level bulletin, consider device operation principle and the difference of difference in functionality piece on sensitivity, can provide the error of 1-2 millisecond during actual judgement.Fault zero calculating constantly is divided into following two kinds of situations: 1) absolute time and the relative time of protection incident are all non-vanishing, and fault zero constantly equals absolute time and deducts relative time; 2) relative time of protection incident is 0, but the fault sequence number is effective, and this is to come between judgement information onrelevant being arranged according to the fault sequence number is whether identical, in this case, the absolute time of event at first be whole device report fault zero constantly.Set the interrelational form of reset time; main in order to adapt to relative time and all invalid situation of fault sequence number, its implementation process is such: given protection reset time, judge that whether two time differences between the information are less than reset time; less than reset time then can be related, otherwise can not.The setting of reset time can rule of thumb provide, and generally is about 20 seconds.Compare with zero moment of fault mode, this interrelational form is not enough strict.
When organizing substation level fault bulletin in the level message processing module of substation, whether what need describe the plant failure bulletin is to judge that the implementation process of judgment principle can be with reference to the accompanying drawings shown in 3 with an electric network fault.In this step; time principle is the primary foundation of fault associating information; consider the asynchronism of information clock in the real system; in judgement, introduced the relation between device; be that the protected primary equipment classification shown in the right side is judged in the accompanying drawing 3, and the time of delivering to the backstage on the information is as the auxiliary judgment condition.Its judgment principle mainly is to depend on three time errors, be respectively with in the interval device between time error, with the station in the device between time error, backstage accept time error, during to time error, think then that twice bulletin is relevant less than given in the fault zero of the device bulletin time difference between constantly; If the fault zero of two device bulletins constantly greater than given to time error, and recently between a period of time device and the backstage communication normal, then accept the time according to the backstage and whether judge less than assigned error whether two bulletins related.
In the message processing module of substation, finish after the association of burst information, need to judge whether this information needs to send main website, mainly contain two purposes: the one, with the shielding of the disturbance information of electrical network in the substation, the 2nd, when fault, send the information that can reflect failure condition on only.In order to realize this two purposes, at first the character of protection event is classified, be divided into startup, outlet, fault parameter, common event four classes, the determinant attribute of action bulletin can obtain according to character type and the parameter of contained event, its implementation process is as follows: if the outlet event is arranged in the bulletin, then the character of this report is the protection action; If the No way out event, then this report character starts for protection; Character is the protection event of fault parameter, mainly refers to range finding, separate etc., can distinguish corresponding parameter value to enrich the bulletin content according to keyword.When having only under the primary fault when starting report, then protect action message all to send on not, report out of order special circumstances if this moment occurred certain relevant record ripple, then record ripple report and the protection down of the out of order interval incident element under reporting and send on whole; When in certain the device report under the primary fault outlet being arranged, then this device report place at interval following all information give on whole.
Main website is to the tissue treatment process of fault message, and is relevant with the performance of substation.When the substation possessed above-mentioned fault message function of organization, the groundwork that main website handles fault message was the associating information of finishing between the different stations; When the concrete fault message correlation function in substation, what main website at first will do is the tissue of finishing the substation fault message, and its organizational process as previously mentioned.The fault message organize models of on the basis of the substation fault message of organizing the correlation of the information between different substation being judged then and being described according to the present invention sets up once complete electric network fault message structure.Whether at first between primary equipment corresponding to judgment means have topology contact, secondly be to judge according to the timing that fault message produces if in the fault message processing procedure of main website, whether can be defined as the judgment principle that produces with electric network fault to the action report at difference station.This organizational process is embodied in the accompanying drawing 3.Wherein, what contact was judged to topology is that process is as follows: 1) at first be whether the protection domain of judging two devices has intersection, classification difference with the faulty equipment original paper in protection classification or the report of record ripple is carried out different processing, be divided into the situations such as circuit, bus, transformer, breaker, consider probability and complex fault processing reliability that physical fault takes place, realize and only to contact be judged as topology with bus equipment; The bypass protection adjusted along with the method for operation of equipment for protection, when normally a certain protection in the route protection withdrawed from when considering actual motion, drop into bypass protection, so the bypass protection interval can be thought and all line segregations all belong to same circuit; 2) secondly being the action report of judging satisfying the topology contact, according to timing the protection action report being carried out association again, when using timing that action report is carried out association, is to adopt the mode of setting time error equally.Adopted two time errors on the implementation, be respectively different stations time error and backstage are accepted time error, during to time error, think then that twice bulletin is relevant less than given in the fault zero of the device bulletin time difference between constantly; If the fault zero of two device bulletins constantly greater than given to time error, and communication is all normal between interior relevant station of a period of time and relevant apparatus and the backstage recently, then accepts the time according to the backstage and whether judges less than assigned error whether two bulletins can be related.3) the auxiliary discrimination principle of another one is if had device corresponding to latest report in the current electric network fault, and is then no longer related; The prerequisite that this principle exists is that protection action and coincidence outlet belong to once moving bulletin.
More than describe the embodiment of the present invention in automatic running in detail, it must be admitted that, this method can not guarantee under any electric network fault can both true(-)running, there is the possibility of associated errors in actual use in the fault message element of mentioning among the present invention, and therefore manual reorganization and editor's function need be provided.In order to guarantee consistent with raw information, between the fault message element of mentioning in the present invention the embodiment of incidence relation only with increase under ID number of level, any one information element can be added from primary fault information or withdraw from easily, an electric network fault Information Organization structure is carried out off-line adjustment and modification, realize the filing management of fault message, convenient inquiry and fault recurrence.
And scope of the present invention should not be limited to these descriptions.Any modification, improvement in principle of the invention scope all belongs to protection scope of the present invention.
