Node;
Specifically, in chain type power network, sent in each 220kV plant stands 3 nodes (first node, section point, Section three
Point) status information give Region control layer, wherein, first node, the 3rd node are that two circuits of corresponding 220kV plant stands break
Face node, each line section node are made up of the double-circuit line between Liang Ge transformer stations, and the section point is corresponding
The mother of 220kV plant stands/block switch section node, mother/block switch section node is by mother or block switch group
Into mother/block switch section node here refers to bus connection switch section node or block switch section node, with Fig. 2
220kV stand exemplified by 1 (or referred to as 220kV plant stands 1), its first node is (or the referred to as line section of section 1 on the left of it
1), its section point is the section 2 (or referred to as line section 2) on the right side of it;
Each 220kV plant stands in the station domain key-course report first node, section point, the 3rd node respectively
Status information to before the Region control layer, it is necessary to first obtain the state letter of first node, section point, the 3rd node
Breath, therefore, the recognition methods of chain type topological structure of electric in one of the embodiments, before above-mentioned steps S101, also

Running status;
Here, current line section node is a line section node for being currently needed for judgement state;
2. if all circuits are in inspecting state in current line section node, the current line section node is inspection
Repair state;
3. if other all circuits are that can throw state in addition to the circuit in inspecting state in current line section node,
Then the current line section node is that can throw state;
If 4. current line section node be not running status, inspecting state, can be in throwing state any one state,
Current line section node is that can not throw state.
The recognition methods of chain type topological structure of electric in one of the embodiments, before above-mentioned steps S101, also
Including:Each 220kV plant stands in the station domain key-course identify the state of each mother/block switch in our station respectively, and
It is true according to default mother/block switch section node decision logic respectively according to the state of each mother/block switch in our station
The status information of mother/block switch section node corresponding to fixed;
Specifically, the state recognition of each mother/block switch of our station " can be transported according to the definition of traditional prepared auto restart
OK ", " maintenance ", " can throw ", " can not throw " four states;
Wherein, the mother/block switch section node decision logic is:
1. if at least two mother/block switches, which are in, divides position or maintenance, and at least one standby can throw mother/point
Duan Kaiguan, then corresponding mother/block switch section node is that can throw state;
2. if corresponding mother/block switch section node is not that can throw state, the mother/block switch section node
For running status.
In the present embodiment, do not consider the inspecting state of mother/block switch section node, be because if mother/point
Then chain type power network can throw node to the maintenance of Duan Kaiguan sections node without other, and this time domain prepared auto restart does not possess operation condition, therefore
Without the concern for.
Step S104:First node that the Region control layer reports according to each 220kV plant stands, section point,
The status information of three nodes, the state letter of the line section node reporting of 500kV transformer stations in the station domain key-course
Cease, the status information for the line section node that the 500kV transformer stations in the Region control layer provide, and the plant stand
The topological structure of the chain type power network is identified for sequence, the middle plant stand number definite value, wherein, in the Region control layer
500kV transformer stations corresponding to line section node as start node, the 500kV transformer stations in the station domain key-course are corresponding
Line section node as end node.
Specifically, the node of node to be searched can be determined according to plant stand sequence and the middle plant stand number definite value
Sequence, node searching is carried out from the start node based on the node sequencing, and record the state letter of the node searched
Breath, end node is directly arrived when completing the search to each node of n-th 220kV plant stands, here, N represents middle plant stand number
Definite value, obtain the topological structure of the chain type power network.In this way, each 220kV plant stands after n-th 220kV plant stands
Node need not scan for again, therefore, be adapted to the change of electric network composition.
Wherein, stand a line section node that the 500kV transformer stations in the key-course of domain report status information according to upper
The line section node state decision logic stated is determined, the circuit that the 500kV transformer stations in Region control layer provide
The status information of section node is determined also according to above-mentioned line section node state decision logic, will not be described here.
Illustrated below by taking the 220kV chain structure power networks in Fig. 2 as an example.500kV station B is in the domain key-courses of station
500kV transformer stations, 500kV stations A are the 500kV transformer stations in Region control layer,
500kV stations B:The line section node that 220kV line section of the station on chain type power network is stood according to 220kV judges
Logic (i.e. above-mentioned line section node state decision logic) provides the status information of a line section node, and the circuit breaks
Face node is as end node.
500kV stands A as identification of the Region control station to chain type topological structure of electric, specifically:
The line section node decision logic that 220kV line sections of the 500kV stations A on chain type power network is stood according to 220kV
(i.e. above-mentioned line section node state decision logic) provides the status information of a line section node, the line section section
Point is used as start node.
Plant stand number definite value, determines the 220kV plant stand numbers between the power supply of chain type power network both ends among setting.
The sequence of transformer station on chain type power network is determined according to chain type power network topology plant stand sequence parameter definite value, and determines chain type
Nodes on power network.
The Topology identification table of chain type power network is as shown in institute's table 1.
Table 1:Chain type topological structure of electric identifies table
If normal one completely go here and there in addition to the power supply of both ends among stand containing n 220kV (situation of consideration actual electric network,
It is that 5 settings substantially can be with meet demand by n maximums), then the string node total number is 3n+2;Assuming that actual chain type power network is as schemed
2, then n be equal to 4, share 14 nodes on chain type power network.Therefore " middle plant stand number " is set to 4, such as table 1, then does not have to judge section
Point 13,14,15 is directly by node 12 to end node.
According to each node status information sent on the plant stand order combining station domain key-course of chain type power network, chain structure is identified
The topological structure and running status of power network.Chain type power network as described by according to Fig. 2 and table 1, then 14 on whole chain type power network
Individual node state is as shown in table 2, therefore the open loop point that the chain type power network can be thrown in the presence of 220kV plant stands 1, other nodes are in
Running status.
Table 2:Each node state table of Fig. 2 chain type power networks
In addition, in order to prevent the first node of each 220kV plant stands, the 3rd node sequence from overturning, a reality wherein
Applying the recognition methods of the chain type topological structure of electric in example can also include:Each 220kV factories in the station domain key-course
Stand respectively according to the plant stand sequence determine corresponding to the first node, the 3rd node.
