Storehouse, according to the corresponding SVG graphical models of the transformer station, the reality of the function in power transformation station name auto-associating network system shape library
It is now that the splicing based on character string dynamically generates its SVG graphical model title in network system, and then is associated with figure
Corresponding graphical model in shape storehouse.
The acquisition of SVG graphical models and the graphical model of the system transformer station are derived from the shape library of network system, according to change
The corresponding SVG graphical models of the transformer station in the title auto-associating network system shape library of power station, the realization of the function is to be based on
The splicing of character string dynamically generates its SVG graphical model title in network system, and then is associated with phase in shape library
The graphical model answered.
Display function of the SVG graphical models in Web is that (HyperText Markup Language are super based on HTML5
Text mark up language) inline mode be directly embedded into webpage to realize.HTML5 supports that 6 kinds of modes show SVG figure moulds
Type：(1) used as picture<img>Label；(2) used as object as CSS background pictures (3)<object>Label is introduced
(4) use<iframe>Label (5) is used<embed>Label (6) uses inline<svg>Label.The system is due to that need to pass through
JAVASCRIPT captures operation of the user on SVG figures to realize interactive interactive function, therefore have selected the third mode and come real
It is existing.
Further, the treatment prediction scheme for being formed, is combining《State Grid Corporation of China is on emergency preplan management method》, with
And《State Grid Corporation of China's regulator control system prevention and disposal large-area power-cuts event emergency regulation》Design configuration prediction scheme system
Make function, will meet power system operating mode requirement, and passed through the accident treatment scheme of safety check, be fabricated to corresponding pre-
Case, and the primary condition of network system operation, the accident plan of establishment, and processing procedure can be obtained in prediction scheme, according to state
The documentation requirements of net company, the standardized Templates specifications of standardization generation；The thing based on power network future models can be also carried out simultaneously
Therefore prediction scheme training and manoeuvre；
Treatment prediction scheme finally consigns to user to be presented in the form of form.In the technical program, prediction scheme form refers to state
The standard of net, realizes the automation standard compliant PDF prediction schemes document of generation.System is based on the value of different content in prediction scheme,
The view CSHTML files that generation Razor view engines are supported, the view file is certainly made in strict accordance with state's network mark；The function
Key technology point is the binary number that the CSHTML view files are converted into PDF by the translation function of iTextSharp controls
According to stream, and then client browser is sent to, is correctly parsed by browser.Subscription client supports turning over for prediction scheme form
The function such as page, positioning, zoom, download.System is directed to all reports, is preferentially customized using template, it is ensured that year is most lifelong
Into the accuracy of version.
As shown in figure 3, prediction scheme of the invention deduces module 40, program management module 41, the structure of user management module 42
Figure, prediction scheme deduces module 40 includes prediction scheme creation module 400 and prediction scheme export module 401, and prediction scheme creation module 400 is configured to
Rule of thumb parameter establishment processes prediction scheme, and is derived prediction scheme is processed to program management module 41 by prediction scheme export module 401.
Program management module
Conventional traffic department has formulated substantial amounts of emergency preplan according to Specification, but the big portion of these emergency preplans
Store point in the form of paper document or electronic document, exist that word description is fuzzy, responsible party divide it is indefinite, answer torrent
Cheng Zhihang is not specific, emergency drilling poor operability, inquiry and the shortcomings of inconvenient retrieval.Program management module can be completed such as
Lower correlation function.Prediction scheme enquiry module 410：The entity object list mapped from SQL SERVER is inquired about, is completed for history
The lookup of data, arranges；Prediction scheme editor module 411：The entity object list mapped from SQL SERVER is updated, is passed through
Entity Framework are write back in SQL SERVER.Realize the amendment in time of the mistake during being created to prediction scheme and update；
Prediction scheme removing module 412：The entity object list mapped from SQL SERVER is deleted, is write back by Entity Framework
To in SQL SERVER.Memory space rationally is utilized, the management of historical archives is realized.
Intelligent grid dispatches emulation of the support system for electric network model, and scheme forming process needs steady based on safety on line
The early warning information of setting analysis application, comprehensive utilization stable state, dynamic data are out-of-limit or hidden to failure present in the current operation of power network
Suffer from, analyze adjustable device, be the safety of power network it is determined that meeting the scheduling auxiliary strategy of multiclass scleronomic constraint and control cost optimization
Operation provides perspective adjustable strategies and supports.
For the different substation information visuallization request that user sends, system is sent to client according to power transformation station name
The corresponding operational view View of end subscriber, contains the SVG graphical models of the visual transformer station in view View, binding
From the corresponding Model model values of transformer station's prediction scheme that Controller controllers get, the acquisition of the Model values passes through
LINQ technologies inquire about Model lists, Table in the SQL SERVER that Model lists are completed from Entity Framework
ORM maps.
User operates the View views of the transformer station to carry out prediction scheme deduction on the basis of visualization, and the system uses JQUERY
The interaction effect to user's operation is realized with CSS technologies, while multiple deduction inputs of user and operation information are temporarily stored into not
In with variable, prediction scheme is completed by the merging of variable in JQUERY and deduces completely collecting for information, customer terminal webpage calls AJAX
Technology sends asynchronous XMLHttpRequest and asks to the Action of backstage Controller controllers, and prediction scheme deduces complete remittance
Total information represents that server end Action is parsed after receiving the JSON information to it using the JSON forms of light-type, parses
Into corresponding Model model entities object, and then Controller controllers are according to the Model model entities object generation of generation
Preview view or derive PDF views that related prediction scheme is deduced.
In the prediction scheme deduction system based on scene, with reference to the accident prediction in area, corresponding picture service, example can be provided
Such as the transmission of static graphics fileinfo, show running status before failure generation in the system picture library, and for area, such as：
The scene of the large area blackout of the important transformer stations of 220KV and 110KV is simulated and sets, at the same can according to before and after trend and
The change of running status, carries out the crash analysis of prediction scheme, and dispatcher's simulation for the demonstration of accident treatment step.
The process of accident prediction is deduced mainly comprising running status before failure, and failure is set, at accident analysis and failure
Reason four processes.
The wherein progress of each link, system provides analysis template, and the Model moulds of transformer station are bound in View views
Type entity information, inquiry operation of the Model entity informations from LINQ technologies, inquiry is completed based on Entity Framework
The ORM mappings of Table in SQL SERVER.
For the formulation of typical prediction scheme, adjusted with being formed according to step operation, county adjusts the report of level, while can be by electricity
The web platforms issue prediction scheme of net service system, for prefecture-level dispatcher, sole duty is checked.
