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 the patterned grid fault recovery path dynamic display method of one.
Background technology
Traditional grid fault recovery path provides with the form or paper of recovering report usually, recover report and mainly comprise the executable switch tool sequence of operation, according to recovering, dispatcher can report that the switch tool sequence of operation provided carries out recovery operation, but the inadequate visual pattern of this display packing, dispatcher needs to read whole recovery report could understand restoration path preferably.
Summary of the invention
The object of this invention is to provide a kind of patterned grid fault recovery path dynamic display method, it is characterized in that, based on VC2010 programming tool, patterned grid fault recovery path dynamic display method comprises the steps:
1) by fault recovery system, route searching is carried out to the non-faulting dead electricity region after electric network fault;
2) search terminate after, by out-of-limit to path trend, switch tool number of operations, busbar voltage are out-of-limit, grid net loss rate, reserve capacity of power grid five indexs carry out superior and inferior evaluating to each restoration path;
3) according to evaluation result, to each restoration path coloured marking, by restoration path Dynamic Announce on graphical interfaces.
When each restoration path of described Dynamic Announce comprises the evaluation index and Dynamic Announce restoration path that show each restoration path, carry out flickering display to needing the switch of action during recovery operation.
After described route searching terminates, by restoration path Dynamic Announce on geographical wiring diagram and electrical network main wiring diagram interface, be convenient to the visual understanding of dispatcher to restoration path.
When the invention has the beneficial effects as follows Dynamic Announce restoration path, the evaluation index list of each restoration path is shown, be convenient to the good and bad degree that dispatcher understands restoration path more accurately, be convenient to the visual understanding of dispatcher to restoration path, to the switch variable color flicker needing in each restoration path to operate, be convenient to dispatcher and carry out operational processes.
Accompanying drawing explanation
Fig. 1 is somewhere partial electric grid electric main wiring diagram;
Fig. 2 is somewhere partial electric grid geographical wiring diagram;
Embodiment
The invention provides a kind of patterned grid fault recovery path dynamic display method.Be explained below in conjunction with accompanying drawing.
The present invention is based on VC2010 programming tool, patterned grid fault recovery path dynamic display method comprises the steps:
1) by fault recovery system, route searching is carried out to the non-faulting dead electricity region after electric network fault;
2) after search terminates, by carrying out superior and inferior evaluating to 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, reserve capacity of power grid five indexs to each restoration path;
3) according to evaluation result, to each restoration path coloured marking, by restoration path Dynamic Announce on graphical interfaces.
As shown in Figure 1, Kingsoft transformer station 2 transformer is faulty equipment, and 220kVII mother is non-faulting dead electricity equipment, and all the other equipment are charging operation equipment, and charging equipment is shown in red on a display screen.After electric network fault, startup separator recovery system is non-faulting dead electricity equipment search supply path.Find three restoration paths altogether, path one refers to switch tool 2200; Path two refers to switch tool 2211,2212; Path three refers to switch tool 2221,2222.According to the out-of-limit rate of path trend shown in table 1, switch tool number of operations, the out-of-limit rate of busbar voltage, grid net loss rate, reserve capacity of power grid five indexs, superior and inferior evaluating is carried out to three paths, obtaining outbound path one is optimal path, path two is sub-optimal path, as shown in table 1.
Table 1 path superior and inferior evaluating table
| The out-of-limit rate of trend | Switching manipulation number of times | The out-of-limit rate of busbar voltage | Network Loss Rate | Reserve capacity of power grid MVA | 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 |
Carry out painted display respectively on a display screen to three paths, path one is optimal path, is labeled as orange, and path two is sub-optimal path, is labeled as green, and path three is again path, is labeled as blueness.Simultaneously to the switch flicker needing in restoration path to operate, represented by dashed line to needing the switch of flicker in the drawings.Fault as depicted in fig. 1, on geographical wiring diagram on a display screen (as shown in Figure 2), the transformer station of faulty equipment is comprised with redness mark, and the restoration path on geographical wiring diagram only between display transformer station, do not show the restoration path being positioned at transformer station, as shown in the path two in Fig. 2, path three.
In sum, the patterned grid fault recovery path dynamic display method of the present invention's design, after efficiently solving electric network fault, fault recovery system to find after restoration path how in the problem of graphical interfaces Dynamic Announce, to different restoration paths mark different colours, be convenient to the good and bad degree of dispatcher to restoration path and carry out visual understanding.By carrying out fault simulation to somewhere partial electric grid, walking along the street path search of going forward side by side, carries out Dynamic Announce to each path at graphical interfaces, obtains good effect, demonstrates correctness and the validity of patterned grid fault recovery path dynamic display method.
The foregoing is only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.All any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., be all included in protection scope of the present invention.
