Description of the drawings
Fig. 1 is the principle of the present invention block diagram.
Specific implementation mode
The following is a clear and complete description of the technical scheme in the embodiments of the invention, it is clear that described embodiment
Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
The every other embodiment that art personnel are obtained without making creative work belongs to the model that the present invention protects
It encloses.
The technical scheme is that increasing data processing application specific processor (FPGA) and dedicated network in a switch
Processing unit D is realized.It should be noted that dedicated network processing unit D may be present but be not limited to be present in interchanger.
Cognitive method, including data processing application specific processor A, institute are moved back in a kind of throwing of layer 3 ethernet switch process layer devices
Some FE GE optic electric interfaces are all drawn from the processor；Dedicated ethernet exchange chip B, at Ethernet data exchange
Reason；Application specific processor C is managed, for carrying out configuration pipe to data processing application specific processor A and dedicated ethernet exchange chip B
Reason, and realize that IEEE1588v2 protocol procedures are handled, dedicated network processing unit D knows for SCD file analysis, IED equipment
Not, business automation configures；GOOSE, SV message that IED equipment generates are inputted by some port, at data application specific processor A
Reason identification message, APPID, data application specific processor A establish the port and the storage table of APPID；Dedicated network processing unit D is led
Enter intelligent substation SCD file, establish IED equipment and the storage table of equipment correlation APPID, two storage table correspondences are compared
Merge and completes to connect and bind relationship between private branch exchange system port and IED equipment.
GOOSE, SV message that IED equipment generates are inputted by some port, through data application specific processor A processing identification reports
Text, APPID, data application specific processor A establish the port and the storage table of APPID；Dedicated network processing unit D imports intelligence and becomes
Power station SCD file establishes IED equipment and the storage table of equipment correlation APPID.Two storage table correspondences are compared into merging
To complete to connect and bind relationship between private branch exchange system port and IED equipment.
Special network processing unit D analyzes SCD file, the especially parts Communication in this programme, obtains IED
Correspondence between equipment and APPID is the key that design, and specific solution principle is as described below.
The parts Communication refer specifically to how IED by accessing points is connected to network.
Process 1, the parts dedicated network processing unit D parsing communication, obtains between IED equipment and APPID
Corresponding table：
Process 2, dedicated network processing unit D perceive IED equipment.Data processing application specific processor A identifies GOOSE, SV industry
Business, establishes switch port and the storage table of APPID：
A certain moment T, dedicated network processing unit D read this table by management passage, based on this table, with APPID
Corresponding IED equipment is obtained for keyword query " equipment and APPID tables ".
It is based on a certain moment T as a result, dedicated network processing unit D can be established " equipment and port table ", identify IED equipment
Relationship is connected and bound between switch port, private branch exchange system will perceive IED equipment in particular port and reach the standard grade.
Process 3, dedicated network processing unit D awareness apparatus exit.
Dedicated network processing unit D sets a timer, 20 seconds periods.Implementation procedure 2 in the timer a certain period, special
It will be generated with the ends network processing unit D and simultaneously " equipment and port table " save as table 1, data processing application specific processor A will empty " end
The storage table of mouth and APPID "；Implementation procedure 2 again in timer next cycle, will give birth at the ends dedicated network processing unit D
Table 2 is saved as at simultaneously " equipment and port table ".
IED equipment appears in table 1 but does not appear in table 2 (all of the port), then can perceive IED equipment from
Line.
For SV messages, timer could be provided as 10 seconds.SV message sampled points are not less than at 4000 points, and transmission intercal is little
In 250 μ s, 10 sampled points of delay, which go out error protection equipment and will alert, reports SV chain ruptures, and is returned after 1s, and communication channel delay is more than
3ms, protection will alert report delay exception, and continuous 10s delay recoveries then alert elimination, thus if interchanger does not receive SV and disappears
The time of breath is more than 10s, then it is assumed that related IED is offline.
For GOOSE message, timer could be provided as 20 seconds.The GOOSE message retransmitted for one, can in messages
The parameter of a subsidiary Time Allowed to Live (generally 10s), the parameter inform that recipient waits for next repeating transmission
GOOSE message maximum duration, if within the time, recipient does not receive the message of repeating transmission, so that it may to be considered to send out
Communicating interrupt is given birth to.Next frame message, recipient are not received in 2 times of Time Allowed to Live times (i.e. 20 seconds)
Send out GOOSE chain ruptures alarm.If thus interchanger does not receive the time of GOOSE message more than 20s, then it is assumed that related IED
Offline, IED equipment is set to IED device offlines.
To sum up, timer is set as being reasonable for 20 seconds.
SV messages:
A kind of message format used by transformer station process layer network analog quantity (current-voltage sampling value) transmission.
GOOSE message:
It is a kind of general object-oriented transformer substation case abstract model that IEC61850 standards define, provides
(such as
Order, alarm etc.) mechanism quickly transmitted, it can be used for tripping and failure wave-recording start etc..
IED equipment:
IEC61850 standards define, and are applied to digital transformer substation.It is made of, has from outside one or more processors
Source receives and any equipment of transmission data or control external source, i.e. multifunction electronic instrument, Microcomputer Protection, controller, in spy
The entity of one or more logic contact tasks is able to carry out under fixed environment in the limited range of interface
IED equipment：
SCD is the abbreviation of substation configuration description in transformer substation IEC 61850 standard,
That is whole station system configuration file.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
