Abstract
The invention discloses an imaging method for dynamically displaying a failure recovery path of a power grid, and belongs to the field of failure monitoring technology of power systems. After a failure happens in a power grid, a failure recovery system is started to search power supply recovery paths. The quality of each recovery path is evaluated, and the power supply paths with different quality degrees are dynamically displayed on an image interface in different colors. Based on a VC2010 programming tool, failure simulation is performed by utilizing a local power grid model in a region, so that the power supply paths are displayed dynamically.
Description
Technical field
The invention belongs to electric power system fault monitoring technique field, particularly a kind of patterned electric network fault restoration path dynamic display method.
Background technology
Traditional electric network fault restoration path provides with form or the paper spare that recovers report usually, recover report and mainly comprise the executable switch tool sequence of operation, the dispatcher can carry out recovery operation according to the switch tool sequence of operation that the recovery report provides, but the inadequate visual pattern of this display packing, the dispatcher need to read whole recovery report could understand restoration path preferably.
Summary of the invention
The purpose of this invention is to provide a kind of patterned electric network fault restoration path dynamic display method, it is characterized in that, based on the VC2010 programming tool, patterned electric network fault restoration path dynamic display method comprises the steps:
1) carries out route searching by the non-fault dead electricity zone of fault recovery system after to electric network fault;
2) after search finished,, grid net loss rate out-of-limit by, switch tool number of operations out-of-limit to the path trend, busbar voltage, five indexs of electrical network reserve capacity were carried out superior and inferior evaluating to each restoration path;
3) according to evaluation result, to each restoration path coloured marking, restoration path dynamically is presented on the graphical interfaces.
When described each restoration path of dynamic demonstration comprised the evaluation index that shows each restoration path and dynamically shows restoration path, the switch that need to move during to recovery operation carried out flickering display.
Described route searching dynamically is presented at restoration path on geographical wiring diagram and the electrical network main wiring diagram interface after finishing, and is convenient to the dispatcher to the visual understanding of restoration path.
When the invention has the beneficial effects as follows dynamic demonstration restoration path, evaluation index tabulation to each restoration path shows, be convenient to the good and bad degree that the dispatcher understands restoration path more accurately, be convenient to the dispatcher to the visual understanding of restoration path, to the switch variable color flicker that needs in each restoration path to operate, be convenient to the dispatcher and carry out operational processes.

Embodiment
The invention provides a kind of patterned electric network fault restoration path dynamic display method.Be explained below in conjunction with accompanying drawing.
The present invention is based on the VC2010 programming tool, patterned electric network fault restoration path dynamic display method comprises the steps:
1) carries out route searching by the non-fault dead electricity zone of fault recovery system after to electric network fault;
2) after search finishes, by the out-of-limit rate of path trend, switch tool number of operations, the out-of-limit rate of busbar voltage, grid net loss rate, five indexs of electrical network reserve capacity are carried out superior and inferior evaluating to each restoration path;
3) according to evaluation result, to each restoration path coloured marking, restoration path dynamically is presented on the graphical interfaces.
As shown in Figure 1, Kingsoft transformer station 2 transformers are faulty equipment, and the 220kVII mother is non-fault dead electricity equipment, and all the other equipment are charging operation equipment, and charging equipment is shown in red on display screen.Behind the electric network fault, starting fault recovery system is non-fault dead electricity equipment search supply path.Find altogether three restoration paths, path one finger switch tool 2200; Path two finger switch tools 2211,2212; Path three finger switch tools 2221,2222.According to the out-of-limit rate of path trend shown in the table 1, switch tool number of operations, the out-of-limit rate of busbar voltage, grid net loss rate, five indexs of electrical network reserve capacity three paths are carried out superior and inferior evaluating, getting outbound path one is optimal path, path two is sub-optimal path, and is as shown in table 1.
Table 1 path superior and inferior evaluating table
| The out-of-limit rate of trend | The switching manipulation number of times | The out-of-limit rate of busbar voltage | Network Loss Rate | Electrical network reserve capacity MVA | The path superior and inferior evaluating | |
| Path one | 5% | 12 | 6% | 6% | 50 | Optimal path |
| Path two | 8% | 10 | 8% | 6．8% | 48 | Sub-optimal path |
| Path three | 6% | 14 | 10% | 7．2% | 49 | Worst path |
Three paths are carried out respectively painted demonstration on display screen, path one is optimal path, is labeled as orangely, and path two is sub-optimal path, is labeled as green, and path three is path again, is labeled as blueness.Switch flicker to needing in the restoration path to operate dots the switch of needs flicker in the drawings simultaneously.Such as fault that Fig. 1 describes, on the geographical wiring diagram on the display screen (as shown in Figure 2), the transformer station that comprises faulty equipment with the redness mark, and only show the restoration path between the transformer station on the geographical wiring diagram, do not show the restoration path that is positioned at transformer station, shown in the path two among Fig. 2, path three.
In sum, the patterned electric network fault restoration path dynamic display method of the present invention's design, after efficiently solving electric network fault, fault recovery system finds behind the restoration path problem that how dynamically shows at graphical interfaces, to different restoration path mark different colours, be convenient to the dispatcher the good and bad degree of restoration path is carried out visual understanding.By the somewhere partial electric grid is carried out fault simulation, the walking along the street path search of going forward side by side dynamically shows at graphical interfaces each path, has obtained good effect, has verified correctness and the validity of patterned electric network fault restoration path dynamic display method.
The above is preferred embodiment of the present invention only, is not for limiting protection scope of the present invention.All any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., all be included in protection scope of the present invention.
