Description
Technical field
The present invention is applied to the dispatching automation of electric power systems field, particularly in electric grid relay protection and the failure information system, and the disposal route of electric network fault report and action report.
Background technology
Development along with computing machine and mechanics of communication; smart machines such as microcomputer type relay protection, aut.eq., fault oscillograph are used in electrical network in a large number; when electric system is broken down or be disturbed; these equipment records lot of data and information, these information have important effect to dispatching of power netwoks operation.The construction of power dispatch data network; make that communicating by letter of dispatching terminal and factory station end is more convenient; this has created good condition for the networking of relay protection and fault oscillograph, can be by networking mode with the information uploading of these smart machines to dispatching terminal, composition electric grid relay protection and failure information system.Clearly propose in " State Grid Corporation of China's dispatching system Eleventh Five-Year Plan ", carry out the research of intelligentized correlation technique of scheduling decision and back-up system, strengthen the information-based and intelligent of power network dispatching system.For this reason; domestic each big grid company or by the mode of networking, is actively carried out the construction of electric grid relay protection and failure information system, provides real time fail information in the electrical network Shi Nengwei scheduling of breaking down; improve the automatization level of scheduling, the auxiliary dispatching decision-making.
It is the critical function of electric grid relay protection and failure information system that the electric network fault report generates automatically; at present; because the difference that each smart machine is handled failure message; the each place has difference to go out expansion again to stipulations; cause the content of the failure message of delivering to the failure information system main website on the each place different with form; and these failure messages are put in order the electric network fault report of back formation in the each place and the format and content of device action report also has different requirements; in system's process of construction; often need to carry out customized development according to requirements of different users; flexibility ratio is little, and the development amount is big.Simultaneously, some are local for strengthening information security, prevent the computer virus infringement, and requiring main station system is UNIX operating system, the requirement that output format that this just reports electric network fault and display environment have proposed the platform compatibility.In order to adapt to the diversity of this demand, the present invention proposes a kind of method of handling the output of electric network fault report template multi-format, this is the new trial of being done on the basis of system's operating experience accumulation.
Summary of the invention
The present invention proposes the method for the electric network fault report template multi-format output of a kind of XML/XSL of employing, its objective is and be to guarantee in electric network fault, by the different-format that send on the different intelligent device and the various information of content, can be intactly by form complete showing on operating platforms such as WINDOWS, UNIX of user's request, and only need not revise Trouble Report module software program and just can adapt to the modification of sending data layout on the intelligent apparatus and user variation the demand of the format and content of Trouble Report, action report by the modification of template.
XML (eXtensible Markup Lanaguage) is a kind of extendible SGML, does not need pre-defined label.The main two types application of XML: web issue and exchanges data.HTML is appreciated that becomes a kind of specific XML file.Because XML do not use predetermined mark, so the implication of mark can not directly be understood, and in order to show XML document, must have a mechanism to describe and how show these data files.XSL (extendible stylesheet language) is the first-selected stylesheet language of XML.
XSL refers to extensible stylesheet list language (eXtensible Stylesheet Language), in order to the conversion and the format of definition XML document, and can be with the display format output of the data among the XML with appointment.XSL comprises that three parts: XSLT (is used to change the language of XML document, the XML data of can filtering and classify, be used for XML document is converted to the language of other types document or other XML document), XPath (a kind of language of navigating in XML document of being used for, make XSLT is convenient to locate in XML), XSL-FO (a kind of language that is used to format XML document.Make the result of conversion become the process of the output format that is suitable for reader or audience's use, as convert the PDF document to, directly printout, even audio frequency output).
Wherein, XSLT is a most important parts in the XSL standard, and it is used for converting an XML document to another XML document (as HTML, XML) or the document of another kind of type.XSLT can also increase brand-new element in output file, or removes some elements.It can be rearranged these elements and element is classified, and test also determines to show which element or the like.The simple theory of this transfer process is exactly: XSL converts an XML source tree to another XML bearing-age tree (or convert an XML source document to another XML result document) with XSLT.
The present invention utilizes XML/XSL to realize the output of electric network fault report template multi-format is specifically comprised following steps:
A) collect the various relevant informations of each regional transformer station electric network fault (comprising information such as protection action, protection alarm, fault parameter, recorder data) by failure information system;
B) shield the difference of sending on the fault data that causes owing to reasons such as stipulations realizations, form consolidation form (as accompanying drawing 1), and the fault relevant information is carried out the XML levels of language describe;
In the hierarchical structure of failure message; the fault parameter unification is treated to the part of incident and promptly handles by event argument; and handle the problem of bringing thus by the XSL template: the event argument that has no corresponding incident; by event id=-1 expression; in the XSL template, filter the protection incident of ID=-1; only handle the event argument of this type of incident, event argument is presented at gauge outfit, filters problems such as double faults relevant information.
C) different according to each zone to the demand of the form of expression of electric network fault report and action report and content, form that electric network fault that different XSL represent is reported and the template of action report;
Wherein, record ripple figure is when forming electric network fault report and action report, not as a big figure output, and be cut into the processing mode of the little figure of a plurality of record ripples output, several little figure are ideally coupled together, promptly make things convenient for the user editor and the paging of setting type again when preserving into html format or office word form, also conveniently browse.
D) the level fault relevant information that XML is described changes into the information of the multi-format that meets different regions demand spanning operation system platform demonstration by the XSL template;
As shown in Figure 3, template changes into HTML by xslt processor for XML data and XSLT (one of XSL standard), and HTML can cross-platformly show on web client and man-machine interface fully.Equally, XSLT and XML can finally be converted to pdf document by xslt processor and certain display engine (as the fop of apache).
E) different interfaces (web client, man-machine interaction program) goes up the failure message that shows html format, and handles relevant hyperlink.
This method shielded since the otherness that intelligent apparatus is realized stipulations and different expanded function bring on the failure message content sent and the uncertain problem of form, adopted the XSL template to deal with changes in demand about electric network fault report and action report demonstration, on the basis of safeguarding a cover XSL template, be beneficial to the stable operation and the cross-platform requirement of program.XSL can be fit to user's multiple demand fully as a kind of development language of analyticity, has good extendability; This template is supported multiple output simultaneously, the data conversion of XML form can be formed HTML, XML, even the PDF document.
Description of drawings
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments,
Fig. 1 is that the fault level of information is expressed;
Fig. 2 is the templating treatment scheme of fault report;
Fig. 3 is the flow process that XML and XSL change into HTML and PDF;
Fig. 4 is two kinds of different action reports (clipped record ripple figure) that same XML data XSL format back shows.
Embodiment
The failure message that failure information system is collected is to represent (as shown in Figure 1) by the hierarchical structure of a complete tree type.Because the expansion difference of each place protective device, stipulations, the format and content of last carry information is also different, and still the preposition supervisor by failure information system is organized into as shown in Figure 1 hierarchical structure with collected failure message.For concrete different area, some failure message increases and decreases to some extent, such as, because protection does not support to send opening into amount before and after the fault, just do not open in the failure message of Shou Jiing so into information such as amounts.This hierarchical structure also can be expanded easily according to the development of total system.
Wherein, the mode difference that fault parameter send on the each place, stipulations are handled different, send on some parameter as certain incident, and some has been expanded separately on the type and has sent, handle for unified, in our hierarchical structure, fault parameter is all handled as the part (event argument) of incident, has the event argument of no corresponding incident like this, and some place requires event argument must be presented at gauge outfit, and can filter duplicate message.These can all be handled by the XSL template fully.
In accompanying drawing 1, each node is some General Properties all, as the attribute of " protective device " node " title " is arranged, " action zero constantly ", " affiliated interval name " etc.And the complete available XML of data of this tree-like hierarchical structure describes.
The hierarchical structure of whole like this failure message is beneficial to the XML language description very much, and simple examples is as follows:

For the fault information data that XML represents, just can pattern be described by the XSL template, display action report and electric network fault report also can be clicked according to the hyperlink in the XSL template definition response report simultaneously, and be user-friendly.
In the process of conversion, XSLT defines the part that is complementary with one or more predetermined templates in the source document with XPath.When having found a coupling, XSLT just converts the compatible portion in the source document to result document; And finally in the result, do not remain unchanged in the source document with the part of any one template matches.XSL can also use one or more templates to define and how export the XML element, with a match attribute template and an XML element are connected, and can also come to define template for a complete branch of XML document with match attribute.As accompanying drawing 3.
Idiographic flow as shown in Figure 2, the fault information data that XML describes, XSL template according to predefined, adopt the xslt processor of the cross-platform libxslt of GNU, change into the information of html format, be presented on cross-platform human-computer interaction interface and the web client, and can in report, produce some hyperlinks according to the XSL template, user-friendly.
The XSL simple examples is as follows:
<？xml?version＝’1.0’？>
<xsl:template?match＝″gridFaultReport″>
<html>
<head>
<title>
<xsl:value-of?select＝″@faultTime″/>-<xsl:value-of?select＝″@faultDesc″
/>
</title>
<link rel＝″stylesheet″ rev＝″stylesheet″ href＝″style.css″
type＝″text/css″media＝″all″/>
</head>
＜body style=" the font-family: ' Song typeface '; Font-size:12pt; Font-weight:400;
font-style:normal；text-decoration:none；″bgcolor＝″#ffffff″>
＜h2 align=" center "〉the electric network fault report＜/h2 〉
……
</body>
</html>
</xsl:template>
XSL can be fit to user's multiple demand fully as a kind of development language of analyticity, has good extendability; This template is supported multiple output simultaneously, the data conversion of XML form can be formed HTML, XML, even the PDF document.
When changing into XML (a kind of special case of the actual XML of being of HTML), carry out the location of XML data by XPATH in the XSLT template, the data of locating among the XML are replaced the content of coupling XSLT template, so just change into corresponding XML or HTML, as accompanying drawing 3.
And when exporting, need use that XSL-FO formats output among the XSL as PDF.At first XML document is converted to the file that is made of the XSL-FO element by xslt processor with the XSLT style sheet.Use certain display engine (as the fop of apache) that the XSL-FO element is converted to pdf document again, as accompanying drawing 3.
In addition, in electric network fault protection and action report, the record ripple is generally as a big figure output, if when at this moment being kept at HTML or office word format file, scheming under the bigger situation, and existence can't be edited, problem that can't paging.Propose will record the processing mode that ripple figure is divided into how little figure, usefulness＜br in HTML for this reason, in doc, adopt the soft return mode several little figure ideally can be coupled together, promptly make things convenient for user's paging of setting type again with editing the back, also conveniently browse.Splicing effect as the little figure of 2 width of cloth in the accompanying drawing 4.
Accompanying drawing 4 is same failure message, after XML describes, by the different action report of different XSL template generations.
More than describe the specific embodiment of the present invention in detail, this method shielded that the otherness that stipulations realized by intelligent apparatus and different expanded functions bring on the failure message content sent and the uncertain problem of form, adopt the changes in demand of XSL template reply about electric network fault report and action report demonstration, on the basis of safeguarding a cover XSL template, be beneficial to the stable operation and the cross-platform requirement of program.And can click according to the hyperlink in the template definition response report, user-friendly.
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.
