Embodiment
Be described in further detail the specific embodiment of the present invention below in conjunction with accompanying drawing, wherein in institute's drawings attached, identical label represents same or similar parts, and the accompanying drawing in instructions is reduced form, only for understanding concrete structure of the present invention.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention.
As shown in Figure 1, be the directory tree that the present invention sets up according to subregion, transformer station, bus, circuit or main transformer level Four certain actual area electrical network.Wherein, N1, GX, NN, BS etc. are subregion; Auspicious week, moral treasured, old liberated area, that hero, Long Lin, Yun Ling etc. are the transformer station under BS subregion under a certain electric pressure; LONGL21, LONGL22 are two sections of buses of a certain electric pressure under Long Lin transformer station; TSQB220_1, TSQB221_2, LONGL21_, PINBA22_2, YOUSL222_, LONGL-Z2 are the element (transmission line of electricity, mother, the main transformer that are articulated under LONGL22 bus, wherein YOUSL222 transmission line of electricity in flow data annotated fall, but data retain, inoperative during calculating).
Be the function menu that in the quick editting function that designs of the present invention, right mouse button clicks appearance as shown in Figure 2, comprise: add bus, delete bus, delete mother, annotation, cancellation annotation." interpolation bus " function is the situation needing newly-increased bus when a certain electric pressure of transformer station has bus, and during transformer station's right-click therefore on directory tree, " interpolation bus " function is just effective." deletion bus " function need specify to delete which bus, and when the bus therefore on directory tree is clicked by right key, " deletion bus " function is just effective." deletion mother ", " annotation ", " cancelling annotation " are only for the element mounted under bus, and the element therefore on directory tree is clicked by right key just effective, it should be noted that, when element is mother, " deletion mother " function is just effective; When element does not have annotated, " annotation " function is effective; Otherwise " cancelling annotation " function is effective.
Below with certain actual area electrical network Long Lin transformer station for example, Fig. 3 to Fig. 8 main presentation be the implementation result of right-click menu function, the data modification effect of what Fig. 9 to Figure 11 showed is element handoff procedure
(1) bus is added.The a certain electric pressure of transformer station needs interpolation one section of bus.By clicking the grand woods station on directory tree by right key, click " interpolation bus ", as Fig. 3 in the menu ejected.After click completes, result, as Fig. 4, adds corresponding data in power flow files.
(2) mother is deleted.Click the mother element on directory tree by right key, click " deletion mother ", as Fig. 5 in the menu ejected.After click completes, result, as Fig. 6, deletes corresponding data in power flow files.
(3) annotate.Click the mother element on directory tree by right key, click " annotation ", as Fig. 7 in the menu ejected.After click completes, result is as Fig. 8, and the mother data in power flow files between the bus of grand woods two ends are annotated.
(4) element transfer bus.Directory tree finds the PINBA22_2 (flat class) be articulated under LONGL22 bus, " PINBA22_2 (flat class) " is clicked with left mouse button, pin left mouse button, " PINBA22_2 (flat class) " is drawn to " LONGL21 " bus on directory tree, now " LONGL21 " can deepen look, unclamps left mouse button and namely completes Ping Ban-Long Lin transmission line of electricity switches mounting bus data modification work at grand woods transformer substation side.Fig. 9 and Figure 11 respectively show Ping Ban-Long Lin transmission line of electricity and switches the flow data before mounting bus and stable data at grand woods transformer substation side, Figure 10 and Figure 11 is the amendment situation of flow data and stable data after transfer bus.
What the present invention proposed realizes bus changing method efficiently based on OO program technic and mentality of designing and has following outstanding advantages: 1. by adopting object-oriented programming method, building topology directory tree, provides operation interface interactive flexibly to user; 2. realize transfer bus and non-productive operation by mouse drag or right-click menu, the circuit or the main transformer that achieve same transformer station can freely switch between different buses, and ensure the unification of flow data and stable data; When 3. avoiding simple artificial amendment one by one, the problem such as large, the fallibility of workload, substantially increases the work efficiency of data edition; 4. method is short and sweet, simple to operate.
