Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
During the embodiment of the present invention is realized, inventor has found pitch point importance blending algorithm of the prior art
In, a kind of node communication net node importance evaluation method (abbreviation prior art one) based on the electric network influencing factor be present, its
Mainly pass through the topological correlation degree between the Shortest Path Analysis arbitrary node between node.Its specific method is as follows：
(1) the definition node electric network influencing factor：Impact analysis of the website in power network with reference to where network node, establishes section
Point electric network influencing factor evaluation system, the evaluation index as communication net node weight.
(2) node relative influence matrix is established：Each index under same index is weighed according to the score value between index
Relative influence.
(3) definition node polymerizing factor：Represent other nodes of nodal distance and consider the weighted average of node weights
Beeline.

(3) node topology importance is assessed：Influenced each other and formed with local message by global information, corresponding index difference
For node betweenness and the inverse of node degree；
(4) analysis node integrated risk value：Node integrated risk be will the node traffic importance that be obtained in step (2) with
Topological importance carries out comprehensive consideration.
However, it is found by the inventors that there are the following problems for above-mentioned prior art two：
What above-mentioned prior art two and prior art one considered is influence of the power network factor to communication net node, therefore together
When the process of establishing of electric network influencing factor index system be present, but service attribute is separately added to evaluation model and worked as by prior art two
In, make the Process of Comprehensive Assessment of pitch point importance more comprehensive.Using two kinds of representative topological importance indexs：Node
Betweenness and node degree.Business Stream and may be not present when real network is run for shortest path between the arbitrary node that the former considers
It is dynamic, and the conclusion that the latter and the important transmission node number of degrees may be not high has differences.And with real network structure not
Disconnected to expand, prior art two will make the assessment of pitch point importance more difficult.Therefore the communication of actual electric network structure is not considered
Net node importance assessment method still has space to be modified in terms of business flowing is reflected.
It is different from above-mentioned prior art one and prior art two, lead to as shown in figure 1, the embodiment of the present invention provides a kind of electric power
Believe net pitch point importance evaluation method, including：
Step 101, according to the voltage class of each node of power telecom network each node of power telecom network is categorized as it is more
Individual level, form power telecom network hierarchy Model.
Wherein, the power telecom network node with same voltage class is divided into same level, and each level is with voltage etc.
Level is arranged from high to low.
Step 102, according to power telecom network hierarchy Model, determine power telecom network node and relative upper strata

Step 103, according to power telecom network hierarchy Model, determine power telecom network node and relative same layer
The same layer cooperation center property value of node.
Step 104, according to power telecom network hierarchy Model, determine power telecom network node and relative lower floor
Node and the convergence center value with node layer.
Step 105, associate according to the upper strata of power telecom network node centrality value, with layer cooperation center property value and convergence
Centrality value, superposition is weighted, forms power telecom network pitch point importance initial value.
Step 106, power telecom network pitch point importance initial value is carried out to linear normalization, formation power telecom network node
Importance normalized value.
The embodiment of the present invention provides a kind of power telecom network pitch point importance evaluation method, each according to power telecom network first
The voltage class of node carries out each node of power telecom network to be categorized as multiple levels, forms power telecom network hierarchical structure mould
Type；Under the power telecom network hierarchy Model, based on the efficiency of transmission (being showed by shortest path between node) between node,
Respectively determine power telecom network node associated with the upper strata of relative upper layer node centrality value, power telecom network node and
The same layer cooperation center property value of relative same node layer, power telecom network node and relative lower level node and same layer
The convergence center value of node, and then power telecom network pitch point importance initial value is obtained, form the important of power telecom network node
Normalized value is spent, so as to evaluate the importance of each node of power telecom network.The present invention can solve to be difficult in the prior art
The importance difference of the similar node of specification configuration, it is difficult to the problem of carrying out the evaluation of power telecom network pitch point importance.
In order that those skilled in the art is better understood by the present invention, a more detailed embodiment is set forth below,
As shown in Fig. 2 the embodiment of the present invention provides a kind of power telecom network pitch point importance evaluation method, including：
Step 201, according to the voltage class of each node of power telecom network each node of power telecom network is categorized as it is more
Individual level, form power telecom network hierarchy Model.
Wherein, the power telecom network node with same voltage class is divided into same level.Generally, support
The voltage class of key power telecom network node 35kV and more than, be generally divided into 500kV, 220kV, 110kV and 35kV tetra-
Kind voltage class, therefore can typically mark off 4 levels.
Step 202, each level arranged from high to low with voltage class.
So, can according to the convergence effect of voltage levels node and the service access feature of low-voltage-grade node
To determine the converging information of each hierarchy node and other voltage class nodes and issue relation, the power communication stratum reticulare being built into
Secondary structural model (can be illustrated only) with 3 levels herein as shown in Figure 3.
Step 203, according to formula：Determine power telecom network node i and it is relative on
The upper strata association centrality value R of node layeri。
Wherein, Vi TCollection is interacted for the upper layer node of power telecom network node i, i.e., is in identical with power telecom network node i
Neighboring communication set of node under the grid nodes covering of level, dijFor power telecom network node i and relative upper layer node j
Between shortest path length.
Specifically, the shortest path between node can embody the node degree of approach, so as to the flat of major embodiment node
Upper transfer efficiency, it is how much unrelated with the aggregation node carried under the node.(saved on upper strata when it reaches all voltage levels websites
Point) distance get over hour, nodal distance network core position is closer, its flow upload efficiency it is higher.
Step 204, according to formula：Determine power telecom network node i and
The same layer cooperation center property value EC of relative same node layeri。
Wherein, SkInteraction is connected for same layer to collect, it is same where the same layer connection interaction set representations power telecom network node i
The set of node in node connection piece k under the power telecom network coverage of voltage class；N is power telecom network node total number.
Herein, it is necessary to which explanation, can be used for observing position criticality of the node in similar node with layer connection piece.
The residing connection piece of node is bigger, shows that it is higher with the extent of polymerization of similar node, and interaction intensity is bigger, thus between these nodes
Cooperation efficiency it is higher；Compared with the node in connection edge, the node-node transmission efficiency in connection piece center is also higher.
In addition, lower floor's access node of node carrying is more, convergence property is higher, then it is assumed that the convergence effect of the node is got over
Greatly.High-level node on the one hand by having converged flow caused by the direct-connected access node of low level itself, on the other hand also between
The traffic aggregation process that take part in many more lower access nodes is connect, therefore to study convergence center.
Step 205, according to formula：TZi=TCi+LCiDetermine power telecom network node i and relative lower level node and
With the convergence center value TZ of node layeri。
Wherein, TCiPower telecom network node i and the convergence center value of relative same node layer are represented,LCiPower telecom network node i and the convergence center value of relative lower level node are represented,Wherein, Sp kTo belong to same level and direct-connected node set with power telecom network node i；Lp kFor
The lower level node set direct-connected with power telecom network node i；TCjFor power telecom network node j and relative same node layer
Convergence center value；RjFor power telecom network node j centrality value is associated with the upper strata of relative upper layer node；LCgFor
Power telecom network node g and relative lower level node convergence center value；RgFor power telecom network node g and with its phase
The upper strata association centrality value of the upper layer node of pass.
Due in the same voltage class node of higher level there is also convergence relation, as shown in figure 4, node 92,94, the former
In the absence of direct-connected higher voltage hierarchy node, thus node 92 using as 94 it is unique can uploading nodes flow is carried out to it
Successively convergence is until 220kV websites 82 indirectly.It can be seen that the convergence center of node will be converged by same layer convergence center and lower floor
Centrality together decides on.
Node convergence center is associated with the convergence center of all access nodes direct-connected therewith with associating centrality, as
The convergence total amount of itself.And while calculate node converges total amount, emphasis simulates the traffic conditions of all access nodes：Aggregation
Poly- amount is higher, shows that the node load is heavier, and its reliability service plays an important role for the maximum integrality of Logistics networks load.
Step 206, according to formula：Superposition is weighted, forms power telecom network
The importance initial value of node i
Wherein, w1、w2、w3Respectively upper strata associates centrality value, with layer cooperation center property value and convergence center value pair
The weighted value answered.
Step 207, according to formula：By power telecom network section
Point i importance initial valueLinear normalization is carried out, forms the importance normalized value L of power telecom network node ii。
Wherein, V represents power telecom network node total collection；Represent the electricity in power telecom network node total collection
The minimum value of power communication net node importance initial value；Represent the power telecom network in power telecom network node total collection
The maximum of pitch point importance initial value；X is the parameter value pre-set, and its span is (0,1), can avoid the occurrence of LiFor
0 unreasonable situation.It is unsuitable excessive for the difference directly perceived for embodying node topology importance, X value.
Preferred embodiment is elaborated below.It is emphasized that what the description below was merely exemplary, rather than
In order to limit the scope of the present invention and its application.
Using somewhere electric power Backbone Communication cable network as experimental subjects, by the phase in the network structure after abstract
Artis and link information are emulated.As shown in figure 4, in the pitch point importance evaluation procedure of the present invention, statistics obtains net
139 nodes, wherein 500kV websites 5, respectively node 18,37,38,43,100,220kV websites 26 are shared in network,
110kV websites 82,35kV websites 26.The node for before ranking 10 integrates importance evaluation result (i.e. quite as shown in table 1
In importance normalized value).
Table 1：10 pitch point importance before ranking：
Observable obtains from table 1, and the voltage class correlation that the significance level of node is corresponding is larger, node voltage
Higher grade, and significance level is higher.Evaluation result has distinguished the pitch point importance of different voltage class, and in ad eundem node
The central careful judgement that can also make relative importance, meets actual motion needs.Pitch point importance ranking is by node voltage etc.
The influence of level, therefore in actual motion, voltage class weight vectors should rationally be set.
Table 2：10 pitch point importance ranking results before ranking under four kinds of algorithms：
The result that the method for the embodiment of the present invention obtains is referred to not differentiating between the pitch point importance of power network hierarchical structure and evaluating
Mark is contrasted, and mainly lists the method for most common betweenness center, node degree centrality number and the embodiment of the present invention most
For these three indexs of the node efficiency of correlation, as shown in table 1,2, obtained through summarizing as drawn a conclusion：
(1) four kind of evaluation all thinks that most important node is 18.It can be seen that while it is as highest voltage level node, and
The most crucial nodes of locations of network under pure topological environmental.
Larger difference be present in the secondary important node ranking under (2) four kinds of evaluations.
1) by taking 500kV nodes 100 as an example, in addition to node degree centrality, it is all in row in other three kinds evaluations
The name important node of first five, and 17, the 18 and 82 node degree centrality numbers to rank the first are 10.As can be seen from Figure 4 220kV
Website 17 and 500kV websites are direct-connected, higher with each upper layer node degree of closeness, and as the direct-connected convergence section of same layer of node 82
Point, neighbor node 82 of the node 17 either all relatively with layer in upper layer node association centrality and convergence center is big, therefore
The significance level of node 17 is obvious higher than 82.But because the grid nodes voltage class supported by it is limited, by its with
500kV nodes 100 contrast, although both are almost identical on convergence center, the difference of association centrality and cooperation center's property
It is different so that comprehensive significance level is high not as node 100.
Therefore, node degree centrality can not be acted in the convergence of node and commented comprehensively with being made on topological core level simultaneously
Valency.
2) 110kV websites 97 are more forward in betweenness center ranking, but in practical topology figure, its lower floor, which does not have, to appoint
Practical significance is not present in what access node, the betweenness center for calculating the node.Depart from power network practical structures, betweenness center method
It will be unable to be applied to pitch point importance evaluation procedure.
3) there is also larger limitation on the premise of power network hierarchical structure is not considered for the evaluation of classical node efficiency：In net
The 220kV nodes 24 of network more core position all have similar topological attribute to 500kV nodes 100, are all most important nodes
18 direct-link node, is computed, its convergence center less than the latter half, if the efficiency of transmission ratio only in accordance with node 17
The latter is high by 10%, obtains the higher conclusion of the former importance, it is clear that be unilateral.
Before each algorithm ranking 10 pitch point importance ranking result is only listed in above table.To analyze the total of all nodes
Body ranking, Ken Deer (abbreviation Kendall) correlation analysis method provided in an embodiment of the present invention and its can be passed through
The ranking correlation of excess-three kind evaluation algorithms：
Assuming that the two ranking sequence Xs and Y, X=(x on N number of node1,x2,…,xN), Y=(y1,y2,…,yN), by X
