Accompanying drawing explanation
Fig. 1 is a kind of circuit diagram of electrical network.
Fig. 2 is that Fig. 1 is converted to the electrical network topology be made up of line between node and node.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Topology analyzing method during a kind of high-performance electric network implementation, comprises the steps:
Step one: the describing mode of application drawing opinion, be a node by the some region representations in electrical network, its inside do not exist affect connecting and disconnecting of the circuit state equipment as all kinds of switch, disconnecting link, circuit breaker etc., wherein be joined together to form by various element the entirety that one has identical electriferous state, all components and parts of each node region are charged or dead electricity simultaneously simultaneously.
Equally, from the angle of graph theory, line between node is regarded as the high abstraction of the switch of connection two nodes, between two nodes, have line segment to connect, represent that the switch of connection two node closes; Without direct line between two nodes, represent that the switch of connection two node disconnects.
Step 2: when all nodes are not all connected with switch, carry out electrical network configuration, comprising: configuration node, configuration node comprise information and configuration association matrix S; Specific as follows:
(1) configuration node: according to the definition of node, mark node Pn, marks electric pressure simultaneously in node, and as run into transformer, then the electric pressure on both sides is different, needs to do special processing.Can suppose that all switches all close, from power supply node, perform BFS (BFS), mark each node voltage grade, run into the configuration change electric pressure of transformer according to transformer, also can manual configuration node.As shown in Figure 1, be a kind of circuit diagram of electrical network, Fig. 2 is that Fig. 1 is converted to the electrical network topology be made up of line between node and node.
(2) configuration node comprises information: comprising: the v_level attribute (can use during topology coloring) of the whether charged isEnergized attribute of configuration node, connected_points attribute (also inquiring this attribute by adjacency matrix) that configuration node current time is connected with other nodes, configuration node electric pressure.
(3) configuration association matrix S: incidence matrices is the matrix of the relation on measuring point and limit.In practical operation, only need in each switch memory node information, can table 1 be obtained according to Fig. 2, as follows:
Table 1:
| S0 | S1 | S2 | S3 | S4 | S5 | S6 | S7 | S8 |
| (P4,P8) | (P1,P3) | (P2,P4) | (P3,P4) | (P3,P5) | (P4,P6) | (P0,P5) | (P0,P6) | (P4,P7) |
Step 3: the static analysis of distribution network: before electrical network comes into operation, according on off state and the incidence matrices S of electrical network, creates adjacency matrix C and the full-mesh matrix L of electrical network;
(1) create adjacency matrix C: according to the on off state of power distribution network, and incidence matrices, the adjacency matrix of power distribution network can be gone out by fast creation.In adjacency matrix, 0 represents that two nodes directly do not connect or switch disconnects, and 1 represents that two nodes directly connect and switch closes.If electrical network is containing n node, then adjacency matrix is C (n × n).Now suppose that S1, S2, S4, S5 in Fig. 2 are closed, according to table 1, obtain adjacency matrix C as follows.
(2) create full-mesh matrix L: because this topology analyzing method mainly lays particular emphasis on the dynamic characteristic of power distribution network, therefore the full-mesh matrix creation method when static configuration can adopt the accurate quadratic method of connection matrix, system now for real-time without particular/special requirement.In full-mesh matrix, 0 represents that two points do not connect, and what 1 expression, two points were directly or indirectly connects together.Full-mesh matrix is indifferent to two nodes and is linked together in which way.In fact, if system is started working when all switches all disconnect, then full-mesh matrix is initialized to the matrix that all elements is all 0, also directly can adopt this topological method.According to adjacency matrix C, suppose the switch S 1 in Fig. 2, S2, S4, S5 close, other switches disconnect, then obtain full-mesh matrix L as follows
Step 4: the dynamic analysis of distribution network: be divided into switch to close according to the change of electrical network and disconnect two kinds of situations with switch:
Situation one: switch closed condition analysis:
First, when the switch s is closed, first obtain two node i of switch connection and the information of j according to incidence matrices, now change the Elements C of adjacency matrix
ijand C
jibe 1, together with expression adjacency matrix interior joint i is connected in node j.Node i is added the connected_points attribute of ingress j, node j is added the connected_points attribute of node i.
The information of two node i be joined together and the electrical island at j place is stored in the i-th row and the jth row of full-mesh matrix.With i-th behavior example, in the i-th row promising 1 this node of element representation be connected with i node.I.e. L
ik=1 (k gets 0-n, lower same) represents that node i is communicated with k, and the i-th row of full-mesh matrix L must be identical with row k.Before switch carries out closed action, the set of all nodes be connected with i of the i-th line display of full-mesh matrix, is designated as electrical island a.The set of all nodes be connected with j of jth line display of full-mesh matrix, is designated as electrical island b.After switch is closed, electrical island a and b connects for same electrical island c.All nodes of electrical island a and b are contained in electrical island c.
Concrete operations are as follows:
I-th row of inquiry full-mesh matrix and jth row (row at node Pi and Pj place), carry out the element being positioned at same column in two row elements or operate, obtains a brand-new array T containing n element, i.e. T
k=L
ik|| L
jk, in T promising 1 the set of element be the electrical island c newly obtained.Array T is rewritten to the row k in full-mesh matrix, k represents all T
kthe value of k when=1.The new adjacency matrix now obtained and full-mesh matrix be switch close after adjacency matrix and full-mesh matrix.More than operation all carries out rewrite operation in original matrix, and the interim array T created discharges after calculating terminates, the memory headroom not outside occupying volume.As the switch S 1 in Fig. 2, S2, S4, S5 close, existing switch S 3 (P3, P4) carries out closed action, and adjacency matrix C is modified to as follows:
Then by the 3rd of full-mesh matrix the, 4 row carry out or operate, and obtain array T as follows, T
k=L
ik|| L
jk
012345678
L3＝[010101000]
L4＝[001010100]
T＝[011111100]
Then by the 1st of full-mesh matrix the, 2,3,4,5,6 row array T rewrites, and obtains L as follows
Note: the isEnergized attribute of two nodes only having switch to connect carries out or is 1 just can change electriferous state, i.e. the electriferous state difference (electrical island c is charged) of switch ends after operating.But in any case, all first change adjacency matrix and full-mesh matrix.If two nodes are all charged or all not charged, the electriferous state of distribution does not change, now without the need to carrying out the operations such as topology coloring.
Situation two: switch off state analysis:
When switch S n disconnects, first obtain two node i of switch connection and the information of j according to incidence matrices.Now change the Elements C of adjacency matrix
ijand C
jibe 0, represent that adjacency matrix interior joint i and node j does not directly connect together.Node i is deleted from the connected_points attribute of node j, node j is deleted from the connected_points attribute of node i.
The information being disconnected two node i of connection and the electrical island at j place is stored in the i-th row and the jth row of full-mesh matrix.Because two nodes in same electrical island M, therefore only need must be searched for from any one execution 1 BFS node i or j before the switch-off.The all nodes be communicated with node can be traversed fast according to the connected_points attribute stored in node.The set of the point that this BFS travels through is designated as electrical island x, then compare with the node in electrical island M, and the point do not traversed is then electrical island y, wherein electrical island x ∪ y=M.When switch disconnects, the electrical island M originally linked together solution may be classified as electrical island x and y.If now still there is path between node i and j, then one in x and y is empty set.Result is re-writed full-mesh matrix L.
Concrete operations are as follows:
If switch is connected with node i and j, then from node i, perform BFS search, the connected_points attribute of query node i, and continue to access to lower floor according to the connected_points attribute of the point obtained.The point had access to is made marks, prevents the node that repeated accesses is identical.Then all traversed nodes are designated as electrical island x, and its available array X containing n element represents, wherein X
k=1, k represents the numbering of the node be comprised in electrical island x.The node be not traversed in electrical island M is designated as electrical island y, represents with the array Y containing n element.Array Y carries out xor operation by the element step-by-step i-th row (n element) of full-mesh matrix and array X (n element) being positioned at same column and obtains, i.e. Yg=Xg ⊕ Lig (g gets 0 ~ n).Then replaced by the row k of full-mesh matrix array X, k allly makes X
kthe value of the k of=1.Replaced by the capable Y of g of full-mesh matrix, g is all values making the g of Yg=1.The new adjacency matrix now obtained and full-mesh matrix are the adjacency matrix after switch disconnection and full-mesh matrix.
Close as S1, S2, S3, S4, the S5 in Fig. 2 is closed, existing switch S 3 carries out disconnection action, then adjacency matrix C is modified to as follows
From node 3, performing BFS search, to obtain array X as follows
012345678
X＝[010101000]
Element Yg=Xg ⊕ Lig in array Y
012345678
X＝[010101000]
Li＝[011111100]
Y＝[001010100]
Array X and Y is write full-mesh matrix L respectively, obtains new full-mesh matrix as follows
Note: the isEnergized attribute of two nodes only having switch to connect carries out and the electriferous state that just can change electrical network when being operating as 1, and namely two nodes are all charged.If the isEnergized attribute disconnecting first-half point is different, then mistake of dishing out.
Step 5: according to new adjacency matrix and full-mesh matrix, carries out electriferous state analysis to each section of circuit and electric equipment, element.
The inventive method processes respectively for the closed and disconnected action of switch, the maintenance of an adjacency matrix C and full-mesh matrix L is carried out after each switch motion, and all can discharge for the array of the interim establishment of rewrite operation, therefore EMS memory occupation is little, and the program easy to use of full-mesh matrix is expanded, as topology coloring, electrical island inquiry etc.
Below the correctness of the inventive method and complexity are analyzed:
One, correctness of algorithm analysis:
Situation one: when switch closes:
If switch S is connected with node i and j arbitrarily.Before switch is closed, node m is any one node with node i in same electrical island, and node n is any one node with node j in same electrical island.When the switch is closed, node i and j must link together, and node m and i links together again, then m and j must link together.N and j is positioned at same electrical island again, then m must be connected with n for same electrical island.
Situation two: when switch disconnects:
Because switch S is connected with two nodes at most, and switch disconnects first-half point is communicated with, thus switch after disconnecting at the most solution be classified as two electrical island.
If switch S is connected with node i and j arbitrarily.Before switch-off, node m is not by arbitrary node that switch S is connected with node i.Node n is not by arbitrary node that switch S is connected with node j.If switch S is path unique between i and j, then, when switch S disconnects, node m and n one is decided to be and is divided into two electrical island.Give counterevidence it, if m and n is now still in same electrical island, because i and m connection, j and n connect, then i can be passed through m and n and is connected to j, and so now switch S is not path unique between i and j, contradiction.
If switch S is not the unique path between i and j, then, when switch S disconnects, node m and n must in same electrical island.Because m and i connects, i and j connects by other paths without switch S, and j and n connects, therefore there is path connection m and n.
Two, algorithm analysis:
This analysis of complexity is mainly for analysis of complexity during system cloud gray model.In fact, if system just brings into operation, then without the need to adopting additive method to obtain initial adjacency matrix C and full-mesh matrix L, because now all elements of C and L is all 0 when disconnecting from all switches.
Situation one: when switch closes:
Adjacency matrix need change two elements, therefore complexity is O (1).Full-mesh matrix needs to perform n time or operation, and the k a be connected together node overwrite is entered full-mesh matrix, performs k rewrite operation.Therefore complexity is O (n).But due to involved are all internal memory operations, and single operation very simple (only need carry out once or computing), therefore real-time performance is fine.
Situation two: when switch disconnects:
Adjacency matrix need change two elements, therefore complexity is O (1).When performing BFS search to node, owing to only needing traversal once, therefore least ideally, need to traverse all n node.Carry out n xor operation simultaneously and perform n rewrite operation to full-mesh matrix, complexity is O (n).Can see single operation simple and fast, wherein the BFS of relative complex also only needs traversal once.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
