Embodiment
The present invention provides a kind of method for drafting and device of electrical network bird pest distribution plan, can solve the problem that relies on artificial drafting, lack of scientific foundation when drawing electrical network bird pest distribution plan in the prior art fully.
As shown in Figure 1, the method for drafting of a kind of electrical network bird pest distribution plan of the present invention may further comprise the steps:
Step S1, the record of existing excision bird's nest in the integration electrical network.The network operation personnel can regularly overhaul each circuit and shaft tower in the network system, if on certain circuit or shaft tower, find bird's nest, then extract, and record should the excision incidents in the electric network data storehouse.
Step S2 calculates the bird's nest density of each shaft tower, and said bird's nest density is the bird's nest number of extracing in the setting-up time.Bird's nest density can think also to a certain extent and be equal to bird pest density that bird's nest density representes that more greatly then bird pest density is also big more.Suppose that above-mentioned setting-up time is 1 year, and the bird's nest number of extracing in this year is 1000,, can representes that then to bird's nest density that should shaft tower be 5 if the bird's nest number of wherein extracing on some shaft towers is 5.
Step S3 carries out cluster analysis according to the bird's nest density of said each shaft tower to bird pest density.
Cluster analysis is called cluster analysis again, and it is a kind of statistical analysis technique of research (sample or index) classification problem.Development along with human sciences's technology; To the classification require increasingly high; So that only be difficult to classify definitely with professional knowledge by rule of thumb sometimes; So people have little by little referred to mathematical tool in the taxonomy, have formed numerical taxonomy, again the technology of multivariate analysis is incorporated into numerical taxonomy afterwards and has formed cluster analysis.Cluster analysis is meant that the set with physics or abstract object is grouped into a plurality of types the analytic process that the similar object of serving as reasons is formed.It is a kind of important human behavior; The target of cluster analysis is exactly on similar basis, to collect data to classify; For example the present invention carries out cluster analysis to bird pest density; Can choose some shaft towers (the bird's nest number of excision) arbitrarily and create a cluster, will all add in this cluster with other close shaft towers of bird's nest number of extracing on this shaft tower then, finally form several clusters for the basis.
As an embodiment preferably, the present invention adopts the K-means cluster algorithm to come bird pest density is carried out cluster analysis through combining with the actual conditions of electrical network, drawing the bird pest distribution plan of science, for the installation of artificial birdcage provides foundation.Need to prove, do not get rid of and to adopt the possibility that is more suitable in other cluster algorithm of current application scene.
The K-means algorithm is the most classical clustering method based on division, is one of ten big classical data mining algorithms.The K-means basic idea is: with k in the space point is that cluster is carried out at the center, to sorting out near their object; Through the method for iteration, upgrade the value of each cluster centre one by one, until obtaining best cluster result.The K-means basic idea is: at first select k object as initial cluster center arbitrarily from n data object; And, then, respectively they are distributed to (cluster centre representative) cluster the most similar with it according to the similarity (distance) of they and these cluster centres for other object of be left; And then calculate the cluster centre (average of all objects in this cluster) of each new cluster that obtains; Constantly repeat this process till the canonical measure function begins convergence.Generally all adopt mean square deviation as the canonical measure function.K cluster has following characteristics: each cluster itself is compact as much as possible, and separates as much as possible between each cluster.
Extend in the middle of the bird pest analysis, the specific algorithm flow process is following:
Input: k (the shaft tower bird's nest density number of choosing), data [n] (all extract the shaft tower density array of bird's nest record);
(1) select k initial center point, c [0]=data [0] for example ... C [k-1]=data [k-1] (c is the set of the shaft tower bird's nest density chosen);
(2) for data [0] ... Data [n] is respectively with c [0] ... C [k-1] relatively supposes with c [i] difference minimumly, just is labeled as i;
(3) be labeled as the i point for all, recomputate c [i]={ all are labeled as data [j] sum of i }/the be labeled as number of i;
(4) repeating step (2) (3), up to the variation of all c [i] value less than given threshold value.
Step S4 can obtain several clusters after the cluster analysis through step S3, and each cluster has been represented different bird's nest density areas, so this step need distinguish the different bird's nest density areas that obtain after the cluster analysis, obtains the bird pest distribution plan.
As an embodiment preferably; For with different bird pest density the showing of visual pattern on same distribution plan; Can the zone of the different bird's nest density that obtain after the cluster analysis be distinguished by color, and represent the size of bird pest density with the depth of color.If promptly a certain field color is dark more, expression is should zone bird pest density big more; In like manner if a certain field color is very shallow, then expression is should zone bird pest density smaller.
Sometimes based on demand to the region situation; The staff can want to obtain the bird pest distribution plan divided by the administrative region; In this case; The present invention can also comprise step S5: according to Administrative boundaries said bird pest distribution plan is cut, obtain certain and set the bird pest distribution plan under the administrative region.
After utilizing employing method for drafting of the present invention to draw out the bird pest distribution plan of science; Just can be according to this bird pest distribution plan at the serious artificial birdcage of regional intensive installation of bird pest; At the bird pest artificial birdcage of the sparse installation of serious area relatively not too, reliable basis is provided to the bird pest work that prevents and treats of electrical network.
Can find out by above scheme; The method for drafting of electrical network bird pest distribution plan of the present invention; Carry out cluster analysis to draw out the bird pest distribution plan according to the data recording of existing excision bird's nest; This model through science comes the method for drafting that science is arranged and managed is carried out in the installation site of birdcage; Can stop to install the way of birdcage, thereby solve the conventional bird pest distribution plan resources allocation difficult problem in drawing, for electrical network provides important references in the management decision of artificial birdcage being installed, prevent and treat aspect the bird pest according to artificial experience; And this method for drafting of the present invention is to combine with the actual conditions of electrical network, has scientific basis, and is with a high credibility, guaranteed the security of power supply, has huge economic benefit.
