Real-time topology active state in power grid result.Specifically such as, some switches have connected power supply point, power supply point can be made to pass through this
Switch and power to power grid, some switch current failures, in inspecting state, it is necessary to the electronics that can be just powered by the switch
Element, it is clear that off position may will be in, the state of these switches all directly acts on power network topology, therefore in this implementation
The real-time topology active state also finally can be also can determine whether in example, with the topological structure of Overall Acquisition power grid, realize that power grid is opened up
The automatic identification flutterred.
The step S130 may include:
Using a node as topological starting point, along power network line building topology node linked list;
The direct-link node of the topological node and/or power supply point are added to the topological node chained list as newly-increased node
In;
According to the initial topology data set for increasing node in the topological node chained list newly, by the newly-increased node
Direct-link node and/or power supply point are added in the topological node chained list as follow-up newly-increased node, until all traversal institutes
There is node, form complete topology node linked list, obtain the power network topology nodal information.
1 node is added in topological node chained list, which as newly-increased node, the initial of node just is increased newly using this
Topological data set, it is possible to determine the direct-link node and power supply point connected around (for example, drawing out) the newly-increased node, repeatedly
Each node and the power supply point that traverse in the power grid that aforesaid operations obviously can be easy are performed, so as to obtain in power grid
By the topological structure of electric switched and power supply point stars are crossed.
This complete topology node linked list can be the topological structure of the whole power grid finally identified.
As further improvement of this embodiment, the step 130 may include:
The initial topology data set A of node m in the complete topology node linked list and the node m are connected directly and appointed
One node n initial topology data sets B of meaning does intersection operation, produces intersection C;Wherein, the node m is the complete topology section
Any one node on point chained list;
Calculate supplementary set Ds of the intersection C relative to the initial data set A;
Node m is identified to add in supplementary set D and obtains data set E;
Intersection C and data set E interior joints are two sector data collection positioned at the node m not homonymies;Wherein, the area
Segment data set is used to characterizing the data set of the node that the power grid section includes and power supply point;
The element number included according to the sector data, determines the section property of each power grid section;Wherein, it is described
Section property includes trunk section and end segments;Wherein, the trunk section is the section for including two or more element;It is described
End segments are only to include the section of an element;
According to the power grid attribute of the node m both sides power grid section, the nodal community of the node m is determined;Wherein, it is described
Nodal community includes trunk node and endpoint node;The trunk node is the nodes that both sides are the trunk section;It is described
End segments are the node that at least side is the end segments.
Take a particular example below:
Below using power network line topology as shown in Figure 2 as example, introduction how to determine the Grid, area attribute and
Nodal community etc. characterizes the information of power network topology current state.As shown in Figure 2, in the power grid, there are 3 power supply points, 5 stations
Institute, 5 rack ceases to be busys switch.Switch is considered as node.Solid blockage represents the switch in conjunction state in fig. 2, hollow small
The switch in isloation state that square represents.This 3 power supply points are power supply point A, power supply point B and power supply point C respectively.Power supply point A
Numbering be 9001, the numbering of power supply point B is 9002, and the numbering of power supply point C is 9003.5 station electricity are station institute 1, institute of standing respectively
2nd, stand institute 3, stand institute 4 and station institute 5.The numbering of each node is respectively from 6001 to 6033.
Utilize the initial topology data set of the step S110 configuration nodes 6001 described in the present embodiment to node 6033, configuration
As a result shown in table 1.
The initial topology data set of 1 node of table configuration
By information channel, distributed devices can obtain data all in above-mentioned table 1.
It can start to build topological node chained list using the step S130 described in the present embodiment, obtain electric topology letter
Breath.For example, by taking node 6006 as an example, initial topology data set be configured to 6006,6005,6007,6008,6009,6010,
6011}.6006 corresponding distributed devices of node are using this node as starting point building topology node linked list, and by direct-link node
6005th, 6007,6008,6009,6010,6011 chained list is added to, is searched with node serial number 6005 for keyword by information channel
For rope to the initial topology data set { 6005,6006,6007,6008,6009,6010,6002 } of 6005 issues, 6002 be newly-increased section
Point, is added to topological node chained list, then the initial topology data set with node serial number 6002 for keyword search to 6002
{ 6002,6001,6003,6004,6005 }, and so on, extend step by step to next stage direct-link node along node is newly increased, directly
The identification of all nodes is completed on to power network line, the corresponding distributed devices of each node identify in table 1 all nodes and
Its initial topology data set.
Power grid section is identified using step S140 described in the present embodiment.For example, by taking 6002 nodes as an example, 6002 with
The intersection of 6003 initial topology data sets is { 6001,6002,6003,6004 }, and the intersection { 6001,6002,6003,6004 } is right
In the supplementary set of 6002 node initial topology data sets be { 6005 }.Data set will be obtained in node 6002 to supplementary set { 6005 }
{ 6002,6005 }.{ 6001,6002,6003,6004 } and { 6002,6005 } two data set node isolates on power network line
Two power grid sections, be 6002 node both sides direct-connected section, two sector datas integrate the left sector number as node 6002
According to collection and right sector data collection.The two sections are increased newly into topological section chained list, it is clear that what the two sector data collection included
Element number is both greater than 1, it is clear that the two Grids are all trunk section;Node 6002 is determined as trunk node.
For another example, it may recognize that the side sector data collection { 6003,6001,6002,6004 } of node 6003, the section is
In the presence of with topological section chained list;Opposite side sector data collection is { 6003 }, is increased newly into topological section chained list, is end segments;
6003 therefore, it is determined that be endpoint node.
Again for example, the side sector data collection { 6001,6002,6003,6004 } of node 6001, another lateral areas be may recognize that
Segment data set is { 6001,9001 }, and comprising power supply point, which is one of power supply section of Global Topological, and 6001 both sides sections are equal
It is trunk node for trunk section, 6001.
All nodes are traveled through, identify all sections on the both sides section, nodal community, topology of each node in topology one by one
And its sector data collection, each section property, the trunk node that each trunk region segment data set includes form the corresponding trunk of the section
Node data collection, so that the topology pass between establishing the node in each section and topological node chained list in topological section chained list
Connection, it is as shown in table 2 for the node both sides section identified and nodal community of Fig. 2 instantiations, each section and its data set,
Section property is as shown in table 3, is to complete the automatic identification of power grid shown in Fig. 2 by above method.
2 power network topology node of table and nodal community
3 power network topology section of table and section property
Certainly when carrying out power network topology identification, in order to avoid because of initial topology data set configuration error
Or the incomplete caused power network topology of information identifies the problem of abnormal, the method further includes in the present embodiment:
Based on the power network topology nodal information, anti-error school is carried out to the initial topology data set of each node
Test, determine the initial topology data set whether configuration error;
If there is the initial topology data set configuration error, initial topology data set configuration error information is exported.At the same time
Pass through the output of error message, using the teaching of the invention it is possible to provide the lifting of the stability and security of power grid.
This usual initial topology data set configuration information whether the verification of mistake, be normally at the step S140 it
Before.Specifically, described be based on the power network topology nodal information, the initial topology data set of each node is prevented
Verify by mistake, including:If the initial data set of the direct-link node of a node includes the node identification of the node, it is determined that the section
