Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A graphic example method based on IEC61850 trouble analysis system, is characterized in that: comprise following two steps:
1, the multi-level logic configuration based on SVG
Native system is used SVG form storage protection logic; support rectangle; text; the basic elements such as curve; also support the self-defined pel shape of <symbol> element definition, <g> component identification pel hierarchical relationship, by <use> element by pel instantiation; definition id attribute is as the unique identification of logic element, and the mapping of setting up pel and logic element attribute.Definition logic diagram as shown in the figure adopts following primitive data to represent:
Edit Text-
Use <use> element to carry out instantiation to this pel as follows:
<use?x=″60″y=″60″width=″200″height=″40″symbol=″logicDraw1″????????????????????????????id=″cd@mode@allTrip″transform=″matrix(1.338,0,0,1.073,-121.817,-15.823)″/>
Adopting <g> element to realize layering shows below:
For example, then the definition of hyperlink: hyperlink utilizes attribute href to indicate the address of hyperlink, <rect href=" tagID### " ... ./>.The definition of algorithm: <use id=" Algorithm_xxx " expressList=" xxx; xxx; xxx " > wherein id indicate the label table of this algorithm, expressList element indicates the attribute set sign that this algorithm relates to.The definition of curve comprises two parts: curvilinear coordinate system <useid=" CoordinateDraw_xxx " expressList=" xxx, xxx, xxx " > wherein id indicate this element for drawing the chart with coordinate system, expressList element indicates the attribute set sign that this graphical dots relates to, curve utilizes <polyline points=160200, 204201, 252186, 298156, 338154 " expression=xxx, xxx, "/> realizes the definition of curve key point to xxx.
2, the intellectual analysis of failure wave-recording
Native system calls MMSEASELiteConnectTo () and connects with device server end: MMSEASELiteConnectTo () first calls get_nextavailable_netindex () and distributes client logic sign, then call mvla_initiate_req_ex () initialization MMS and connect and ACSE (ISO ACSE), set up afterwards readjustment index.After initialization success, software is quoted different service identifiers and is called MMSEASELiteService () and realize various service operations, transmit MMS_SERVICE_FDIR parameter query file directory, inter-process is by mvla_fdir () execute file catalog request, utilize waitReqDone () monitoring whether within the wait-for-response time, to obtain correct execution response, then calling call back function completes software and obtains the various operations after file directory, user selects the file that will download from file directory, software transfer MMSEASELiteService (), transmit MMS_SERVICE_GETFILE parameter, call getFile () and download this file, getFile () utilizes MMS-Lite interface mvla_fopen (), mvla_fread (), mvla_fclose () realizes service, and call call back function and complete and download successfully or failed subsequent operation.Required file is all downloaded complete, calling MMSEASELiteDisConnect () disconnects: first mvla_concl () sends and connects the request of termination, waitReqDone () waits for after request response, del_clientinfo_byindex () deletion client logic sign and del_callbackinfo_byindex () readjustment index.
As shown in Figure 2; visual logic realization adopts the operate condition of a certain moment logic element of mode inverting of layering demonstration; ground floor shows the flow process of protection action in whole record ripple; the second layer is listed the discharge state of a certain moment protection action for protection motion flow; the 3rd layer presents the triggering reason of a certain protection outlet in detail, which logical action element action just to cause protection outlet by.Every layer of displaying contents all adopts SVG form to be stored in the * .des of record ripple paper series.The visual logic of layering shows provides preliminary total sight to understand, the analysis mode of successively deeply probing into, and wherein each level enters and exits by element hyperlink and complete.The sequence chart that visual layering logic shows is as follows:
Visual logic demonstration is divided three classes: protection motion flow, logical framework demonstration, logical diagramization show:
Protection motion flow shows according to reading element-specific sign <use id=" ProcessDraw_xxx " >; obtain and need the intake embodying to identify; by reading recorder data list; generate the list of protection motion flow; the display mode of data and position in dynamic assignment list; finally complete, as shown in Figure 3.
Logical frameworkization shows; the logic that realizes protection action element shows; but; the block diagram that contains logical operation with door or door, NAND gate etc.; need to import into the current state of input element; call gate mathematical algorithm obtain output, thereby determine gate logic block diagram put action look still return to look, as shown in Figure 4.
(3), the demonstration of logical diagram: for the impedance operator of distance protection; the protection motion analysis of the calculation of complex such as the ratio braking of differential protection; analysis in the past need to carry out hand computation and just can analyze according to relevant current data or resistance value the reason of protection action; by calculating these data, draw impedance operator figure and ratio brake analysis chart herein; make to analyze more intuitive and reliable; take ratio Braking Analysis figure as example
Intelligence curve need to be drawn two class graphical informations:
The first kind is relevant to coordinate system, with the irrelevant graphical information of time shaft, they are only relevant with the definite value of current intelligent electronic device, as long as definite value is constant, these information can not change, mainly contain X-axis, Y-axis, initial point and the ratio braking curve of drawing out by differential current definite value and stalling current definite value, be implemented as follows: definition <use id=" CoordinateDraw_xxx " expressList=" xxx, xxx, xxx " > wherein id indicate this element for drawing the chart with coordinate system, expressList element indicates the attribute set sign that this graphical dots relates to, while resolving element, according to attribute set sign, reading analysis list obtains, in the parsing SVG form stage, draw complete.
Equations of The Second Kind information is relevant to time shaft, according to currency, real-time rendering is around ratio braking curve, embody the graph data of current action situation: t moment stalling current is transverse axis coordinate figure, t time difference streaming current is ordinate of orthogonal axes axle. triggers while redrawing interface information groove dragging time shaft, program according to recorder data list read differential and stalling current, be converted to and float in the upper and lower some data of ratio braking curve.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
