Description
Technical field
The invention belongs to power system telecommunications technology system regions, more particularly to a kind of pilot protection multiplex channel fault location
Method.
Background technology
With fiber optic communication and the development of Protection Technology, power line main protection more and more employs logical based on optical fiber
The differential protection in road.Supertension line generally uses multiplex channel due to due to line length.Supertension line protects passage
Once break down, the property of protection and the necessary rapid failure judgement of Communication Personnel, position, and channel service is repaired in time.
In channel failure process, a crucial step is exactly to be accurately positioned trouble point.Due to the intermediate link that multiplex channel is related to it is many, passage
Trouble point investigation location difficulty.Channel failure localization method general both at home and abroad and flow process investigation problem are slow at present, and
Need to rebuild communication link to realize fault location, destroy original communication running status and environment, it is impossible to realize that passage is online
Fault location.
On the other hand, passage operation maintenance personnel must to fiber optic communication principle and protection with communicate cooperation be appreciated and understood by depth
Carve, and principle, method and the flow process positioned with good channel failure, there could be a clearly thinking in troubleshooting,
Can quick, correctly fix a breakdown, recover the normal of passage.The path monitoring method being previously mentioned in CN103616160A needs to increase
Plus channel unit is individually monitored, what is can monitored is only fiber direct connection passage, the energy automatic alarm when optical fiber occurs to rupture,
But the fault location to multiplex channel can not be realized；The channel failure monitoring method mentioned in CN101825668A is by mould
Intend channel failure, the transmission performance of passage is detected, the related content of multiplex channel fault location is had no.
The content of the invention
The purpose of the present invention, is to provide a kind of method of pilot protection multiplex channel fault location, and which can not destroy
Under original communication running status and environment, the quick positioning of pilot protection multiplex channel trouble point is realized, it is not necessary to increase extra
Equipment, it is achieved thereby that the positioning of channel failure point.
In order to reach above-mentioned purpose, the solution of the present invention is：
A kind of method of pilot protection multiplex channel fault location, including following content：
A. increase the byte for channel monitoring in pilot protection multiplex channel transmitting message, in channel monitoring byte
Define independent channel failure；
B. each monitoring of equipment channel case forwarding channel transmitting message in passage；
C. when monitoring of equipment is to channel failure in passage, channel monitoring byte is changed, equipment is only capable of modification correspondence in passage
The byte position of this device channels trouble point, and continue downward forwarding channel transmitting message；
D. channel failure point is reported to the police and is sent by protection device；
E. after channel failure recovers, channel monitoring byte is recovered by equipment, and channel failure point is reported to the police and returned by protection device.
In the above A, the position and independent channel failure for defining channel monitoring byte corresponds.
In the above A, when passage point failure is monitored, the corresponding position of Air conduct measurement byte becomes 1, independent passage
Failure is corresponded with channel failure point.
In the above C, in passage, equipment is only capable of the byte position for changing this device channels of correspondence trouble point.
The concrete mode of the above D is：When protection device monitors channel failure, by recognizing in channel monitoring byte
Position be whether 1 to carry out fault point；If there is byte position to be 1, send corresponding channel failure point and report to the police；If byte position is all
0, then protection device will correspondence itself channel monitoring byte position become 1, and send channel failure point warning.
After such scheme, the present invention proposes multiplex channel Online Fault self-diagnosis technology, it is not necessary to increase extra
Equipment, only increases some expenses in passage message, it is achieved thereby that the positioning of channel failure point, can mitigate passage dimension significantly
The workload of shield personnel, can placed channel out-of-the way position rapidly, the rapid pilot protection that recovers normally runs.
Description of the drawings
Fig. 1 is that longitudinal differential protection system multiplex channel connecting link of the present invention and trouble point divide schematic diagram；
Wherein, 1 to 12 for definition trouble point, link 3/4 is considered as same trouble point, and this fault distinguish at two needs logical
Communication network equipment is supported；Link 9/10 is same with this.
Specific embodiment
Below with reference to accompanying drawing, technical scheme is described in detail.
As shown in figure 1, the present invention provides a kind of method of pilot protection multiplex channel fault location, the guarantor in transformer station 1
Protection unit A is received and dispatched optical fiber through a pair and optical signal is converted to after the signal of telecommunication by photoelectric conversion device A, is accessed by cable logical
The optical transmission device A of credit, completes the signal of telecommunication to the photoelectricity in offside transformer station 2 using the transmission channel of optical transmission device A and B
The transmission of conversion equipment B, photoelectric conversion device B convert electrical signals to optical signal transmission to protection device B.In table 1,2 institute of table
Under the channel monitoring byte definition shown, the method realization of pilot protection multiplex channel fault location is as follows：
1 channel monitoring byte 1 of table is defined
2 channel monitoring byte 2 of table is defined
A. increase the byte for channel monitoring in pilot protection multiplex channel transmitting message, in channel monitoring byte
Define independent channel failure；Wherein, defining independent channel failure in channel monitoring byte is in channel monitoring byte
Well-determined, concrete mode is：The position and independent channel failure for defining channel monitoring byte corresponds；Monitoring to lead to
During road point failure, the corresponding position of Air conduct measurement byte becomes 1, and independent channel failure is corresponded with channel failure point；
B. each monitoring of equipment channel case forwarding channel transmitting message in passage；
C. when monitoring of equipment is to channel failure in passage, channel monitoring byte is changed, equipment is only capable of modification correspondence in passage
The byte position of this device channels trouble point, and continue downward forwarding channel transmitting message；
D. channel failure point is reported to the police and is sent by protection device；
Concrete mode is：When protection device monitors channel failure, by recognizing whether the position in channel monitoring byte is 1
Carry out fault point；If there is byte position to be 1, send corresponding channel failure point and report to the police；If byte position is all 0, protection dress
Put and the correspondence channel monitoring byte position of itself is become into 1, and send the warning of channel failure point.Specific in Fig. 1, protection device A and
Protection device B is according to the warning to send trouble point corresponding with channel monitoring byte of the channel failure point shown in table 3, table 4；
3 channel failure point of table is corresponding with channel monitoring byte
4 channel failure point of table is corresponding with channel monitoring byte
E. after channel failure recovers, channel monitoring byte is recovered by equipment, and channel failure point is reported to the police and returned by protection device.
Above example technological thought only to illustrate the invention, it is impossible to which protection scope of the present invention is limited with this, it is every
According to technological thought proposed by the present invention, any change done on the basis of technical scheme, the scope of the present invention is each fallen within
Within.
