Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1, the distributed feeder automation method based on network peer-to-peer communications that the present invention provides a kind of, including with
Lower step:
Step S101 configures processing terminal for all switches of rack of power feeder.At each switch corresponding one
Terminal is managed, passes through optical fiber between processing terminal to be connected to the network, constitutes network topology.
Step S102, by predetermined set interaction topology information between the processing terminal.
Specifically, processing terminal of the invention is arranged according to preset time in route fault-free, fixed time broadcast processing is eventually
A locating rack of end and processing terminal are the location of in a rack.
Step S103, when route generates failure, the processing terminal adjacent with the fault point detects fault message.
When a failure occurs it, processing terminal detects that power feeder generates failure, broadcast transmission fault message, itself detection
To fault message or after receiving the fault message that other processing terminals are sent, starts feeder automation logic, utilize power feeder
The difference of fault point power supply side and load side fault message can fault point by distributed computing.
Step S104 carries out Fault Isolation processing according to fault message.
Step S105 after all processing terminals receive isolation successful information, obtains available recovery according to network topology
The switch of non-faulting section power supply.
The present invention can control the switch trip close to fault point two sides after completing fault location, complete Fault Isolation.Therefore
After phragma is from success, the successful signal of Fault Isolation is issued using network communication, according to network frame topology, processing terminal automatic seeking
The power supply point that can be restored electricity is looked for, the power supply of non-faulting section is restored.
Detection logic of the invention is as shown in Figure 2-5, and by above-mentioned processing, the present invention can not largely put into construction master
In the case where standing, quick positioning, isolation and the restoring power supply in non-broken-down section of power feeder line failure are realized, big unison raising supplies
Electric reliability reduces power off time, reduces the working strength of electric power operation maintenance personnel, provides strong branch for power failure maintenance
Support.
Referring back to embodiment illustrated in fig. 6, a kind of typically method of the distributed feeder automation based on network communication
Application scenarios, all switches of rack of power feeder, which are respectively mounted, has processing terminal of the invention (automation equipment), when
When route generates failure, feeder automation processing can be carried out.
When operating normally, topology information is periodically interacted between processing terminal, making each processing terminal can establish completely
Network frame topology structure of power feeder.When route is when diagramatic curve position generates failure, processing terminal detects route
Failure interacts fault message.
Since the SW2 that the CB1 on front side of fault point is switched and SW1 is switched on rear side of the fault message detected and fault point is switched
It is different with the SW3 fault message that detects of switch, by the distributed computing of processing terminal, can fault point be located at SW1
Between switch and SW3 switch.
The haplotype distribution terminal control SW1 switch and SW2 switch of SW1 switch and SW2 switch separate at this time, realize failure
Isolation.
After being isolated successfully, the processing terminal of SW1 switch and SW2 switch issues isolation successful information.All processing terminals
After receiving isolation successful information, by distributed computing, can select SW4 switch and SW8 switch is available recovery non-faulting
The switch of section power supply.By sort algorithm, a preferential selected switch is as the switch and conjunction for restoring the power supply of non-faulting section
The upper switch, then can restore the power supply for not having faulty section between SW2 to SW4, to complete entire feeder automation process.
In conclusion the present invention provides a kind of distributed feeder automation method based on network peer-to-peer communications, including
Following steps: all switches for rack of power feeder configure processing terminal；It is set between the processing terminal by predetermined
Set interactive topology information；When route generates failure, the processing terminal adjacent with the fault point detects fault message；According to failure
Information carries out Fault Isolation processing.Preferably, the present invention can also carry out recovery processing after detecting fault message.Whereby,
The present invention utilizes network low latency, and the extra operational capability of the characteristic and automation equipment of high speed uses distributed computing
Method realizes fault location, and isolation and non-faulting section restore, and improves power supply reliability, and avoid existing master station-centralized
The shortcomings that feeder automation and on the spot coincidence formula feeder automation.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe
It knows those skilled in the art and makes various corresponding changes and modifications, but these corresponding changes and change in accordance with the present invention
Shape all should fall within the scope of protection of the appended claims of the present invention.
