Specific embodiment
With reference to embodiment, the invention will be further described.
Embodiment one：As shown in Figure 1, the distribution network model that a kind of connectedness for electricity distribution network model is verified is opened up
Connectivity checking method is flutterred, including two aspects of analysis are extracted based on Hierarchical clustering analysis and based on topological model.
It is based on Hierarchical clustering analysis：After the feeder line hierarchical relationship of electricity distribution network model extracts single-line model, gathered
Alanysis and obtain several cluster islands, cluster island be divided into the main island comprising root feeder line section or power supply and not comprising root feeder line section and
Power supply from island.When being more than 1 for clustering island quantity（Unit feeder model is there may be to be divided or other feeder line model quilts
Mistake is appointed as the situation of this feeder line）Breadth-first search is carried out, between the quantity and each cluster island according to cluster island most
Short distance and primarily determine that the overall connectedness of feeder line, i.e., primarily determined that from the beeline between Dao Daozhu islands according to each
The overall connectedness of feeder line.If the beeline very little not between homology group, can primarily determine that the two islands are probably connection
Property；If two islands, apart from excessive, can primarily determine that small-scale may be not belonging to this feeder line from island.Wherein include power supply
The Dao Weizhu islands of point, other are from island.
For example it is assumed that needing the feeder line F for checking, the distribution that the ID inquiry distribution net equipment hierarchical relationships according to F belong to F is opened
Pass, feeder line section set, cluster analysis is carried out further according to its equipment connection.As shown in Fig. 2 as a result potentially including three clusters
Island C1, C2, C3.The scale of C1 is 1 for the scale that the scale of 13, C2 is 2, C3.Because the quantity for clustering island is more than 1, count respectively
Calculate each beeline C2-C1 from Dao Daozhu islands：G1, C3-C1：B5B4B3B2B1.It can be seen that from terms of hierarchical relationship angle, C1-
C2 may be belonging to the situation that an island, i.e. "current" model have " segmentation "；C3 is probably that other feeder plant mistakes are poured into F
In feeder line.
However, in general, hierarchical relationship is not necessarily reliably.Therefore need to be carried out using the topological relation of distribution network model
Assistant analysis.
Extracting analysis based on topological model is：Extracted according to decimation rule by the feeder line topological relation of electricity distribution network model single
After line model, based on general place-and-route algorithm（Such as elastic force placement algorithm）Generation distribution topological diagram, so as to according to distribution
Distribution topological diagram is regenerated after the decimation rule of the overall connectedness of topological diagram assistant analysis feeder line or modification single-line model simultaneously
Carry out assistant analysis.
Refer to be laid out based on elastic force according to the distribution net equipment model set for extracting based on general place-and-route algorithm
Algorithm is laid out, and generates distribution topological diagram.Detailed process is：Mathematical modeling is carried out according to distribution net equipment model set, will be opened
Close, feeder line section is abstract is " side ", it is " point " that tie point is abstract, construct a figure G.Tearing the stretch fabric of power model open using gravitation
Office's algorithm is laid out, and is coloured according to switch, feeder line segment type and node type, forms readable distribution topological diagram.
It refers to again to be searched according to particular topology into figure to carry out connectivity analysis or modification model extraction rule according to topological diagram
The topological diagram binding hierarchy cluster result of rope rule generation is analyzed, while can for example be expanded with correction model extraction condition
The modes such as maximum search depth, regenerate topological diagram, carry out generalized analysis, determine this feeder line reasonable topology boundary and
Internal connectivity.
For example, extracting single-line model by feeder line topological relation, the rule of model extraction including starting as shown in figure 3, advise
Then：Specify node number, selection feeder line object；Search rule：The normal fortune side that is carried out according to switch contact type topology, according to opening
The maximum step for close the real-time remote signalling topology real-time fortune side for carrying out, specifying maximum search depth；Termination rules：Specify major network section
Point, non-circuit station institute.
It is laid out based on elastic force placement algorithm further according to the distribution net equipment model set for extracting, net topology is matched somebody with somebody in generation
Figure.As shown in figure 4, wherein：
The hollow node of light color：Represent major network node；
Dark hollow node：Represent distribution ordinary node；
Dark solid node：Represent distribution bus nodes；
The solid node of light color：Represent distribution distribution transforming or load bus；
Double-head arrow line：Represent closure cut-offs kind equipment；

Black line：Represent common feeder line section；
Whole distribution network contact diagram can be coloured according to the affiliated feeder line of equipment.
Global alignment analysis chart 2 and Fig. 4, it can be seen that cluster island C2 should belong to the scope of feeder line F, C3 is not belonging to feedback
, there is model hierarchy exception in the scope of line F.Additionally, as the basic function of assistant analysis instrument, mould can be readjusted here
Type topology decimation rule, expands topology visualization scope, again comparative analysis.
The present invention simultaneously ancillary information comprehensive assessment such as bonding apparatus title in terms of hierarchical relationship and topological relation two
A kind of distribution network model connectedness quality, the problems such as solving distribution network model relation " overlap ", lack, there is provided the connective inspection of distribution network model
Checking method, is distribution network model quality check work provided auxiliary technological means, General Promotion Distribution Network Practical analysis level.
The above embodiments merely illustrate the technical concept and features of the present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implement according to this that it is not intended to limit the scope of the present invention.It is all according to the present invention
