Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Power distribution network self-healing application system constantly perfect, the efficient foundation of the crucial framework of self-healing, in realizing power distribution network self-healing process, the high speed of power distribution network production real-time running data is intensive, how effectively allowing service data realize self-healing function, is key of the present invention, and the present invention uses the information development technology of present main flow, further investigate, develop, carry out data mining for high speed, intensive data.Set up four-dimensional data target information pool, a kind of efficient distribution network system data intelligence self-healing exchange method is provided.
The realization flow of distribution network system data self-healing exchange method provided by the invention as shown in Figure 1, the present invention adopts J2EE as technological core, power distribution network real-time running data index is carried out rationalization utilization, life cycle to index, the index definition key factor, the coherent application of achievement data, the index hook is checked relation and is made up four-dimensional index application message pond, realize the index bracketing method, the data that hit the target realize the intersection various dimensions application of data target in the real time execution process, finishing the risk oneself healing of data adjusts, use dual array locational decision method, realize effective reduction of data, and the fault of collector carried out effective and reasonable verification, concrete steps are as follows:
(1) data acquisition unit gathers power distribution network real-time running data index;
(2) make up four-dimensional index application message pond;
Four-dimensional index application message pond comprises that index life cycle, index definition key factor, achievement data are used and the index hook is checked relation.
(3) adopt the index bracketing method to make up 4 grades of relational application of one-dimensional degree achievement data;
With the four-dimensional index of power distribution network real-time running data respectively with the association of comparing of the four-dimensional index of other service datas, with the achievement data of all one-dimensional degree according to its four-dimensional index cross correlation in twos, the final level Four relational application that forms one-dimensional degree achievement data that makes up.
The index bracketing method mainly refers to use by the real time execution achievement data being carried out one point data, 4 grades that make up one-dimensional degree achievement data concern the magic square application, the index hook is checked the cross-reference of relation, and effective excavation of data depth realizes risk profile assessment and the self-healing of power distribution network.
The index bracketing method has made up multilayer index network of personal connections in length and breadth, adopts the realization flow figure of index bracketing method as shown in Figure 2, and it is mainly realized in the following manner:
1. gather the data message value of the real-time achievement data of operation;
2. key factor (Key Term in the index definition), the coherent application of achievement data, the index hook of the life cycle of nominal data, definition index are checked relation, finish the multistage crisscross of operating index;
3. index contrast, mined information being carried out the ms level pushes: index contrast and information excavating refer to that the achievement data that the index bracketing method is made up the level Four relational application of one-dimensional degree achievement data excavates comparison, obtains valuable information, such as Risk-warning information.
4. finish the quick Risk-warning of operation of power networks index.
(4) data target intersection various dimensions are used;
(5) adopt dual array localization method that achievement data is reduced, and the fault of data collector is carried out verification.
In the information compilation process, as the variable elements A, real time data is configured to the dual array of index as the variable element B with index, and dynamic-change information makes up array of pointers.
The self-healing of data height intelligence is realized based on the index bracketing method in dual array location, finishes data and effectively reduces the DSH process.
Data are in the high speed acquisition process, the data that gathered by single extraction are because the restriction of data value itself, only finished the application of achievement data, it is defined dual array, realize that in the group unit operation of power networks computation process merges, calculate through trend, the efficient algorithm fusion such as load prediction, the index that produces in the index cyclic process is used, intersect the power grid risk early warning that produces with index, finish the data height intelligence self-healing of real time data index, realize effective reduction DSH of data, and the fault of collector is carried out effective and reasonable verification, adopt the realization flow of dual array location as shown in Figure 3, comprise the steps:
＜1〉determines dual array: power distribution network real-time running data and the dual array of four-dimensional index constitutes;
＜2〉the dual array after determine merging: adopt trend in the power distribution network operation computation process to calculate and Load Forecast Algorithm carries out verification to power distribution network real-time running data and four-dimensional index, with the dual array of the data definition after the verification after for fusion;
＜3〉the dual array after merging intersects with data target that various dimensions are used and the power grid risk early warning is combined, and finishes that data are effective reduces and to the verification of data collector fault.
Collector belongs to terminal device, breaks down such as failure problems such as the superfluous unrest of situation generating program such as extraneous factor network interruptions.
If data acquisition unit breaks down, might cause the achievement data that gathers not accurate enough, exceed continuously the index normal range such as majority parameters data under this collector, at this moment just can not be simple data are carried out self-healing reduction, but need to carry out the verification alarm to the collector fault.
For the in-problem achievement data of a certain possibility on certain node in the power distribution network, can adopt trend in the power distribution network operation computation process to calculate and Load Forecast Algorithm etc., recalculate this achievement data of this point, and carry out verification, if this achievement data has problems really, then with the data that calculate it is covered reduction.
If the achievement data major part of certain collector collection all goes wrong or goes wrong for a long time etc., then may there be fault in this collector, will carry out the collector fault warning.
Distribution network system data self-healing exchange method provided by the invention, well solve the market demand bottom carries out oneself's control to data when carrying out risk assessment problem, the raising power distribution network is unusual, voluntarily diagnosis, isolation and the recovery capability of fault, improves management work efficient.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present invention.
