Description
Technical field
The invention belongs to intelligent substation technical field of automation.More particularly to a kind of intelligent substation secondary deficiency and excess link
Topological Mapping method.
Background technology
In traditional transformer station, secondary circuit is transmitted based on point-to-point cable information, and the information of transmission channel is to supervise
Control, the state of passage is also knowable, also there is no so-called virtual link.And in intelligent substation, secondary circuit by
Hardwire mode is changed into empty circuit type, with optical fiber circuit come data communication information of shared procedure layer etc..
The framework of secondary circuit can be subdivided into and directly adopt straight jump, directly adopt that net is jumped, net is adopted net and jumped etc. in intelligent substation.Directly adopting
Under the straight network architecture jumped, because empty loop and actual fiber loop are one-to-one relations, deficiency and excess can be very easily realized
The mapping and monitoring in loop.And also there are many intelligent stations at present is that net is jumped and net adopts the framework that net jumps and carries out capital construction based on directly adopting
Or technological transformation, the simultaneous transmission multiple signals in each optical fiber under this framework, it is impossible to go from direct external physical line
Whole secondary circuit is analyzed, secondary virtual circuit is the substitute is.
The topology of secondary virtual circuit in passing through whole station configuration file (SCD file) in intelligent substation to describe transformer station
Structure, including sampled data (SV) control block, GOOSE control blocks (towards the abbreviation of the transformer substation case of general object), IED it
Between subscription information and process layer communication physical port information etc..But these information are incomplete, it is impossible to complete two
The mapping relations of secondary deficiency and excess link, so as to cause when virtual circuit breaks down, it is impossible to which which bar physical link ring judgement is
Section breaks down.
The content of the invention
To overcome the shortcomings of in prior art, the present invention provides a kind of Topological Mapping of intelligent substation secondary deficiency and excess link
Method, that is, realize the mapping between virtual link and real physical links, enables operation maintenance personnel intuitively to obtain virtual link
With the corresponding relation of physical link, when a certain bar virtual link breaks down, its corresponding all physics can be quickly obtained
Link, to facilitate follow-up lookup trouble point.
The technical solution used in the present invention is：
A kind of Topological Mapping method of intelligent substation secondary deficiency and excess link, it is characterised in that include：

In virtual local area network No., Port represents actual physics port, and VLAN-ID is the numeral between a 0-4095, represents the thing
Virtual local area network No. belonging to reason port, represents that some physical port only allows to forward VLAN and physical port VLAN-ID to set
Consistent message is put, Port and VLAN-ID can have multiple.Increase the network information of neighbor port node simultaneously.
In step 2, with four-tuple D (<Device name-board number-port numbers-VLANID>) defining port, the wherein whole story
The VLANID of port is 0, and all of port definition constitutes model P.
The incidence relation C set up between port, C=<D1-D2>Represent the incidence relation between two ports.To become successively
The corresponding relation of power station network all of the port is deposited in relational database, generates the model P, P=of the physical port of whole station
{ C1, C2, C3, C3 ... }, each Cn represents the connection status of a physical port, and model P is the connection of all physical ports
Set.
Parsing SCD file, obtains secondary virtual circuit, and the virtual link is the network topology knot in units of control block
Structure, while the receiving port of virtual link can also be accessed.The topological structure cannot be mapped directly in physical topological structure.
In step 2, extend SCD file, show definition device control block sending port, with four-tuple Vn (<CBName-
Both port of origination-end port-VLANID>) defining a virtual link, all virtual links constitute model V=V1, V2,
V3, V4 ... }, each Vn represents a virtual link, and each of the links receives and dispatches port by control block title, and VLANID is only
One represents.
In step 3, the P-V relational models of generation include, the quaternary of all of physical port incidence relation and virtual link
Group definition composition.
In step 4, corresponding physical link set is found according to the definition of virtual link, according to port definition in physics chain
All spanning trees of certain Single port are searched in the model P of road, is confirmed and void according to receiving port and VLAN-ID in all spanning trees
Intend the corresponding physical link set of link.
The invention has the beneficial effects as follows：
(1) present invention provides the virtual link of whole station and the topological corresponding relation of physical link, contributes to lifting transformer station
The direct feel and O＆M level of operation maintenance personnel.
(2) when intelligent substation communication failure, the present invention can rapidly orient the void according to the virtual link of failure
Intend the corresponding physical link path of link, facilitate operation maintenance personnel rapid to failure with reference to the monitoring means of other physical link states
Positioning, contributes to lifting the O＆M efficiency of transformer station's operation maintenance personnel, reduces O＆M cost and time.
(3) invention is not affected by intelligent substation network topology structure, contains shadows of the VLAN-ID to network topology
Ring, be applicable to directly adopt directly jump, the intelligent substation that the frameworks such as net jump are adopted in net jump, net directly adopted, with the very strong suitability.
