Embodiment
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only a part of embodiment of the application, rather than whole embodiment.Embodiment based in the application, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all should belong to the scope of the application's protection.
Referring to Fig. 1, the figure shows the flow process of an embodiment of the electrical network SCADA alarm information processing method based on expert system tool that the application provides, this flow process comprises:
Step S101: the SCADA warning information is read in to the information analysis pond;
The SCADA system is as data acquisition and supervisor control, its internal gathering has a large amount of power equipment data, these information datas need to meet some specifically rule, while not meeting, will embody with the form of warning information, in actual application, these warning information will produce in large quantities, for ease of the application, alarm be carried out to the intellectual analysis processing, first these information be read in to the information analysis pond.The information analysis pond can be a memory device that possesses memory function, the SCADA warning information read in can be arranged in order according to the order (time) produced, during specific implementation, often acquire a SCADA warning information, this warning information is stamped after timestamp to the form storage with a piece of news.In addition, can also sub-category storage on the basis according to Time alignment, to facilitate subsequent treatment.
Step S102: the interpretation of rules mechanism according to the rule correspondence of storing in the expert system tool rule base is found out the incidence relation between warning information to warning information analyze in the information analysis pond, in described rule base, the rule of storage comprises mode section and action part, and interpretation of rules mechanism corresponding to described rule comprises the interpretation of rules mechanism to mode section;
Read in the SCADA warning information enormous amount in the information analysis pond, still, these warning information, in not independent generation in the same time, are stored in the information analysis pond with discrete form.Yet may there be association in the SCADA warning information, by the related discrete message of these tools of analysis-by-synthesis, will obtain some significant electric power events, thereby utilize this electric power event to carry out decision-making, improve the accuracy and efficiency of electric power system dispatching.Based on this, the application is analyzed according to interpretation of rules mechanism corresponding to rule in the expert system tool rule base the SCADA warning information read in the information analysis pond, to obtain the incidence relation between warning information.Here " incidence relation " between warning information refers in the regular hour scope, causing the dependent event generation or causing in the process of power grid cascading reaction the relation existed between the corresponding warning information formed when each event occurs due to a certain event.For example; certain interval 1 circuit fault that is short-circuited; but the not tripping of interval 1 switch, cause higher level interval 2 switch overstep trippings, the warning information such as interval 1 overcurrent I segment protect action, interval 2 overcurrent II section actions, interval 2 switch motions (separating brake) are the warning information with incidence relation.Rule in the expert system tool rule base can comprise mode section and action part, mode section can limit the incidence relation between the SCADA warning information, and action part is that the SCADA warning information meets the respective handling action that needs carry out after the condition that mode section sets.Expert system tool can need to be set series of rules according to actual conditions.Rule is different, concrete resolving to rule may not, such as, comprise simultaneously a plurality of " from " the interpretation of rules mechanism of the rule of logic and the rule that simultaneously comprises a plurality of "or" logics is different, the former need to analyze between the SCADA warning information " with " relation, the latter need to analyze the "or" relation between the SCADA warning information.
Expert system tool can have multiple way of realization, such as, PROLOG, Clips etc., these instruments respectively have characteristics, and PROLOG has successful application at aspects such as electric network failure diagnosis, equipment fault diagnosis, operation order generations.The inside of these expert's tool storage rooms has rule base, and rule base provides interpretation of rules mechanism, and this interpretation of rules mechanism can be controlled and search for matching strategy by reasoning and be found two incidence relations between the SCADA warning information.
Step S103: the action part output that will there is the corresponding rule of warning information of incidence relation;
After finding the incidence relation between warning information by abovementioned steps, the application is immediately by analysis result output, but the corresponding action part of the warning information that has incidence relation in analysis result is presented in face of the user.Rule can be divided into mode section and action part as previously mentioned, and mode section is used to indicate the conditional information in analysis result, and action part is used to indicate under electric power is controlled needs the operation of carrying out.Generally, conditional information partly belongs to the bottom-up information after expert system analysis, and this information is for the power scheduling personnel, unimportant, and important is action part, and which needs to take operate to overcome the alarm problem that the SCADA warning information embodies.For this reason, the analysis result that the application will meet the mode section condition chooses, then action part of selected analysis result output by these.
After the electrical network SCADA warning information treatment technology scheme based on expert system tool that the present embodiment provides is read in the information analysis pond by the SCADA warning information, directly do not represented or simply divide classification after represented, but by the interpretation of rules mechanism of the rule correspondence in the expert system tool rule base, warning information is analyzed, obtain the incidence relation between warning information, then analysis result is exported according to default mode.Compared with prior art, the technical scheme of the present embodiment provides the function of finding the incidence relation between warning information from the discrete message of magnanimity, thereby can find in time fault or abnormal conditions in electrical network, and these situations are offered to the power scheduling personnel, improved the accuracy and efficiency of power scheduling decision-making.In addition, the present embodiment the time is not exported the whole of analysis result in output, but advanced line output rule match (being the coupling between mode section and action part), only by the action part output of the analysis result that meets the demands.
Although above-described embodiment can be realized the application's goal of the invention preferably,, in actual application, based on various special requirements, can suitably improve or be out of shape above-described embodiment.Below exemplarily provide three kinds of modes of texturing of the improvement to above-described embodiment:
One of mode: as previously mentioned, in the electric power system dispatching process, the SCADA system will produce a large amount of warning information, and the aspects such as the classification of these alarms, character, attribute are different, some warning information can embody some current ruuning situation of electric system, and some warning information may not have much value, if all warning information are carried out to the nondistinctive unitized processing of milli, may cause processing the waste of resource.For this reason, the application has designed the strobe utility to the SCADA warning information.This mechanism, before the SCADA warning information is read in to the information analysis pond, is first read in the information filtering pond by the SCADA warning information, in the information filtering pond, the classification of SCADA warning information is differentiated.Typically, the SCADA warning information can be divided into five kinds, be accident information, abnormal information, displacement information, out-of-limit information and inform information, this five category information is for the value difference of carrying out correlation analysis: for the information of informing or normal displacement information, having little significance of correlation analysis, therefore, if judge and find that warning information belongs to this two category information by classification, can give up these information, it is not read in the information analysis pond and carry out analyzing and processing; For accident information, abnormal information or out-of-limit information; analyze the abnormal or failure condition that can find in time in electrical network; being conducive to the very first time provides valuable information to the power scheduling personnel; therefore; if judge and find that warning information belongs to the information of these classes, is read into it in information analysis pond and carries out analyzing and processing by classification.By above-mentioned filter operation, make the information analysis pond obtain " weight reducing ", rejected interfere information, be conducive to improve efficiency and the accuracy that follow-up warning information is analyzed.
Two of mode: in the above-described embodiments, when the SCADA warning information is analyzed, do not have to limit the quantity of once warning information being analyzed, in actual application, can an information of an information be analyzed, analysis that also can one group of information of one group of information.When the SCADA warning information is analyzed according to the mode of group, by the relevance problem related between group and group, when analyzing the SCADA warning information of this group, the information association of possible this group is to the information of other groups, make only to consider that the precision of analysis that this group warning information obtains is not high, for this reason, the application provides the method that the relevance between group and group is got rid of, i.e. the concept of dynamic (variable) time window.Particularly, the application first reads front and back two groups of SCADA warning information in succession from the information analysis pond according to default Fixed Time Interval, for example: suppose that the information analysis pond stores warning information with time sequencing, Fixed Time Interval is T, the 0th, read the SCADA warning information in the first period constantly, SCADA warning information in T read for the second period constantly, SCADA warning information in 2T read for the 3rd period constantly, the like, here front and back two groups of SCADA warning information in succession are as warning information group and the T warning information group constantly in the 0th moment, perhaps warning information group constantly of T and 2T warning information group constantly etc.After reading out SCADA warning information adjacent before and after two groups, these two groups of warning information are compared, two kinds of situations will occur in result relatively:
One is that two groups of warning information do not have relevance.In this case, even if illustrate last group of warning information analyzed, its can not relate to yet after one group of warning information, last group of warning information has independence for rear one group of warning information, at this moment can carry out the analytical work to the warning information of last group.Simultaneously, next the group warning information after rear one group of warning information is read in circulation, and then rear one group of warning information and its next the group warning information read are compared, and analyzes its relevance;
Two is two groups of relevant property of warning information.In this case, illustrate that last group of warning information can not carry out analyzing and processing at once, because it is carried out to analyzing and processing, one group of warning information after relating to, if do not include rear one group of warning information in the consideration category, may arrive and cause analysis result inaccurate.At this moment, the application increases a Preset Time length by Fixed Time Interval, the Fixed Time Interval that soon from analysis cell, reads the SCADA warning information is elongated, take this elongated Fixed Time Interval as basis again, again read two groups of SCADA warning information, like this, the warning information originally belonged in second group of SCADA warning information may enter into the first group of SCADA warning information again read, this first group of new SCADA warning information may no longer have relevance with second group of new SCADA warning information thereafter, if also there is relevance, can repeat aforesaid operations, finally make two groups of warning information that read from the information analysis pond become independent, lose relevance.Referring to Fig. 2, in fact provided the concept of dynamic time window by said process, in the situation that two groups of warning information that read have relevance, this dynamic time window can be elongated, until the relevance between two groups of warning information that " cutting off " reads.Above-mentioned Fixed Time Interval, Preset Time length can be determined according to actual conditions, and by considering various factors, the preferred Fixed Time Interval of the application is 6S, and Preset Time length is 3S.
Three of mode: in the application's implementation procedure, be the technical scheme computerize by the application, can will be converted into program language in above-mentioned processing procedure, utilize the control and the search matching technique that become language itself to realize event and regular analysis coupling.But there is obvious problem in the mode of this direct code: the one, the effect of visualization of knowledge base is bad.If analysis process is write sentence by sentence with high level language, that determined information generated processing knowledge can only be the programmer, and the power scheduling personnel are limited to the structure of knowledge of himself, can't participate in visually among Design with Rule; The 2nd, due to the effect of visualization do not had, the power scheduling personnel can not participate in the generation of expert system tool rule base, the power scheduling personnel can only offer the program staff by the experience of oneself and professional knowledge, be converted into program statement by the program staff, once rule needs additions and deletions, still need programmer's participation, this mode will make the formation efficiency of rule base low, have influence on the processing to the SCADA warning information.For this reason, the application be take expert system tool as basis, improves the visualization that the SCADA warning information is analyzed, exported by the transformation to expert system tool.The Clips expert system tool of below take describes as example: Clips is a forward direction derivation language based on the Rete algorithm, it adopts the C language compilation, there are the characteristics such as high transplantability, high scalability, powerful knowledge representation ability and programming mode, just this characteristics and with the close relation of C language, for the analysis of carrying out warning information based on the Clips instrument, visual providing is provided may.The application is on the knowledge representation layer of expert system tool Clips, utilize the C language to be improved the interface of Clips alteration ruler, encapsulation forms visual rule and generates interface, like this, the power scheduling personnel can be by the Clips interface formation rule interpreted library after improving, then Clips saves as text by this rule automatically according to the Clips grammer, when the SCADA warning information is analyzed, interpretation of rules driver by Clips is resolved the text of preserving, utilize the interpretation of rules mechanism that analysis result is corresponding to realize the analysis to the SCADA warning information.Can at least obtain the more excellent effect of two aspects in this way:
The one, programming and execution efficiency are improved.The improved regular interface that power scheduling librarian use Clips instrument provides is write the warning information analysis rule, can aspect power scheduling personnel new rule be placed among the Clips rule base, for the programmer, its programming organization is simple, with respect to simple, with the C Plus Plus programming efficiency, can improve more than 30%, the reasoning while carrying out concrete warning information analysis is controlled execution efficiency and can be improved more than 50%;
The 2nd, there is good effect of visualization.On Clips rule execution level, generate interface by C language compilation rule, and the rule definition at this interface operation is converted into to the regular text that Clips needs, and changed the abstract and readable problem differed from of the code of Clips own, make the dispatcher can easily participate in regular formulation and verification.After having had above-mentioned visual basis, the output of previous embodiment also can adopt visual interface to realize.Referring to Fig. 3 (a) and (b), wherein: the top that Fig. 3 (a) shows rule generation ，Gai interface, interface is mode section, in bottom, is action part; Fig. 3 (b) is the visualization result of output.
For the application's technical scheme is described, below again with one more specifically embodiment (embodiment bis-) the application's technical scheme is explained.Referring to Fig. 4, the figure shows the flow process of this embodiment.This flow process comprises:
Step S401: the SCADA warning information is read in to the information filtering pond;
Step S402: judge the category attribute of the current SCADA warning information read from the information filtering pond, if the warning information category attribute be displacement information or inform information, perform step S403; If the information category attribute is accident information, abnormal information, out-of-limit information, perform step S404;
