Specific implementation mode
Decentralized bus protection system embodiment
In the present embodiment, decentralized bus protection system (referred to as decentralized bus protection) using cable directly sample with
Cable directly trips, and external input and output use standard connector, is installed on the spot close to primary equipment.Therefore, distributed busbar
The decentralized bus protection handset repair method used in protection can be adapted for the distributed busbar arranged close to primary equipment
Protective device.
Decentralized bus protection includes N number of bus protection handset (hereinafter referred to as handset), N >=2, each complete phase of handset
Together, the specific number of N is configured according to actual needs.In the present embodiment, decentralized bus protection uses building block design, most
It is big to be configured by 4 handsets.It is connected with each other by communication line between each handset, each handset can obtain other each handsets
Relevant information in the present embodiment, is connected between each handset by kilomega optic fiber Ethernet, and the inside of highly reliable seamless redundancy is formed
Special Double-direction double-ring net, each handset can obtain the relevant information of other each handsets, also, each son by the Double-direction double-ring net
Machine being capable of complete independently whole defencive function.Also, the fixed M interval of access of each handset, is responsible for corresponding M interval
The acquisition of analog quantity and switching value and sequential trip outlet, the numerical value of M >=1, M are set according to actual conditions, this implementation
In example, M=8, then, each handset fixes 8 intervals of access, is responsible for the acquisition of the analog quantity and switching value at corresponding 8 intervals
With the sequential trip outlet at corresponding interval.Each handset has SV, GOOSE, MMS unification of three nets optical port output function, which adopts
With 100,000,000 optical fiber interfaces, wherein SV data output formats are IEC 61850-9-2, sample rate 4kHz.All handsets all access
It protects private network, each handset that can issue SV messages, receives and dispatches GOOSE and MMS messages, wherein SV messages include corresponding handset institute
The analog quantity information of acquisition interval, GOOSE sends the trip signal that message includes a whole set of bus protection and corresponding handset is acquired
The switching value information at interval, it is spaced start failure protection signal that GOOSE, which receives message,.
Fig. 1 is a kind of specific handset arrangement schematic diagram of decentralized bus protection, and certainly, the invention is not limited in this
Specific implementation.
Each handset is respectively provided with N number of maintenance pressing plate, that is to say, that each handset is pressed maximum handset number setting handset and examined
Pressing plate is repaiied, how many handset, each handset is respectively provided with how many a maintenance pressing plates, each maintenance pressing plate in each handset and each son
Machine corresponds.By in this present embodiment, site decentralized bus protection maximum is configured by 4 handsets, then, each handset
, totally 4 maintenance pressing plate corresponding with handset 1, handset 2, handset 3 and handset 4 is all set.
Existing bus protection mostly uses Centralized layout, i.e., completes whole defencive functions with a protective device, because
The problem of this is overhauled there is no single handset, and decentralized bus protection completes whole defencive functions jointly by more estrade machines, when
There are problems that single handset maintenance when primary equipment maintenance or plant failure.
(handset of the maintenance is known as to overhaul handset) when some handset is overhauled, which puts into all handsets
Corresponding maintenance pressing plate, each handset other than the maintenance handset put into maintenance pressing plate corresponding with the maintenance handset, than
Such as：When needing to overhaul handset 2, handset 2 be exactly overhaul handset, then, handset 2 puts into handset 1, handset 2, handset 3 and handset 4
Corresponding maintenance pressing plate, handset 1, handset 3 and handset 4 put into maintenance pressing plate corresponding with handset 2.It is all to overhaul handset input
The processing mode of maintenance pressing plate put into other each handsets other than overhaul handset and overhaul the corresponding maintenance pressing plate of handset
Processing mode it is different, wherein when overhauling handset and putting into the corresponding maintenance pressing plate of all handsets, i.e., handset 2 puts into all sons
When the corresponding maintenance pressing plate of machine, the corresponding analog quantity information of maintenance handset is only received, does not receive the corresponding simulation of other each handsets
Information is measured, the protection act behavior that this processing mode can verify maintenance handset further overhauls the protection act of handset
The specific verification process of behavior is：Electric current is applied by relay-protection tester when handset is overhauled, is detected and is filled by administrative unit
Whether the sampled value set and application electric current are consistent, can examine maintenance handset current loop correctness；Moreover, corresponding by applying
Current verification protection act behavior, such as：Differential protection should be moved reliably when applying 1.025 times of differential protection starting current definite values
Make, differential protection should reliably be failure to actuate when applying 0.975 times of differential protection starting current definite value.For other than overhauling handset
Any one handset, i.e. handset 1, handset 3 or handset 4, when the corresponding maintenance pressing plate of input maintenance handset, i.e., input is sub
When 2 corresponding maintenance pressing plate of machine, these each handsets other than overhauling handset no longer receive the corresponding analog quantity of maintenance handset
Information, and the analog quantity information interaction between these handsets (each handset i.e. other than overhauling handset) is unaffected.
Therefore, because decentralized bus protection completes whole defencive functions jointly by more estrade machines, when primary equipment overhauls
Or there are problems that single handset maintenance when plant failure.N number of son is corresponded to respectively provided with N number of maintenance pressing plate in each handset
Machine need to put into the maintenance pressing plate of all handsets in the maintenance handset when certain estrade machine overhauling, overhaul handset at this time and only connect
The analog quantity information of oneself is received, does not receive the corresponding analog quantity information of other each handsets；Other handsets need to only put into maintenance
The maintenance pressing plate of machine, other handsets, which no longer receive, at this time overhauls the corresponding analog quantity information of handset, and other than overhauling handset
Each handset between analog quantity information interaction it is unaffected, therefore the maintenance of single handset does not interfere with the normal operation of protection.
Moreover, when single handset maintenance pressing plate input, primary equipment corresponding with the handset is already off, has not had in secondary circuit
Electric current, therefore other handsets no longer receive the corresponding analog quantity information of maintenance handset, do not interfere with the normal operation of bus protection.
Because when handset is overhauled, needs to apply electric current by relay-protection tester and examine maintenance handset current loop and protective value
Correctness, if other handsets receive maintenance handset, corresponding analog quantity information may cause the bus protection of normal operation to miss
It is dynamic, therefore other handsets cannot receive the corresponding analog quantity information of maintenance handset.And it overhauls handset and only receives the simulation of oneself
The influence of other handsets can be isolated in amount information, be used for the inspection of bus protection performance.
Decentralized bus protection completes whole defencive functions jointly by more estrade machines, when normal operation each handset definite value and
Pressing plate is completely the same.When the definite value of some handset or pressing plate inconsistent with other handsets, show the definite value or pressing plate of the handset
There is exception, false protection may be caused, therefore latch-up protection is needed when each handset definite value and inconsistent pressing plate.Therefore, usually
In the case of, i.e., system normal operation when, to carry out the inconsistent differentiation of definite value, pressing plate between each handset and alert.When maintenance handset is thrown
When entering the corresponding maintenance pressing plate of all handsets, it is also desirable to carry out the inconsistent differentiation of definite value, pressing plate, wherein when maintenance handset input
When the corresponding maintenance pressing plate of all handsets, maintenance handset is alerted and is exited with the definite value of other each handsets, the inconsistent differentiation of pressing plate,
He exits definite value, the inconsistent differentiation logic of pressing plate of each handset and maintenance handset.It is deposited when primary equipment maintenance or plant failure
The problem of single handset is overhauled.When certain estrade machine overhauling, the maintenance pressing plate of all handsets is put into the maintenance handset,
His handset need to only put into the maintenance pressing plate of the maintenance handset, and the pressing plate input state of other handsets and maintenance handset is to differ at this time
It causes, and overhauls handset there is still a need for complete independently bus protection function tests, therefore no longer differentiate maintenance handset and other handsets
Definite value it is whether consistent with pressing plate.
Further, respective definite value, pressing plate are calculated as transmitting by internal proprietary Double-direction double-ring net after CRC by each handset
It gives other each handsets, each handset to carry out definite value, pressing plate consistency discrimination by comparing corresponding CRC information, one kind is given below
Concrete implementation process：Each handset is using respective definite value, the pressing plate data block total as one, using cyclic redundancy check code meter
Calculate CRC：Splice R check codes again after K information codes, entire code length is N, and therefore, this coding is also named (N, K)
Code.For given (N, a K) code, it can prove that there are the multinomial G (x) that a highest power is N-K=R.According to G
(x) check code of K information can be generated, and G (x) is called the generator polynomial of this CRC code.The specific of check code generated
Cheng Wei：Assuming that the information to be sent is indicated with multinomial C (x), C (x) is moved to left into R (can be expressed as C (x) * 2R), such C (x)
The right will vacate R, here it is the positions of check code.The remainder obtained with C (x) * 2R divided by generator polynomial G (x) is just
It is check code.Any one code being made of bit string can be only with a coefficient ' 0 ' and ' 1 ' value it is multinomial
Formula corresponds.Such as：1010111 corresponding multinomial of code is x6+x4+x2+ x+1, and multinomial is x5+x3+x2+ x+1 pairs
The code 101111 answered.Each handset independently carries out definite value, pressing plate consistency discrimination by CRC information.Each handset receives it
After the CRC information of his N-1 handset, the CRC information of oneself is compared respectively with other handsets, if the CRC letters of oneself
Breath maintenance pressing plate inconsistent with the CRC information of any one handset and the handset is not put into, is reported definite value, pressing plate inconsistent and is closed
Lock protection.
Then, maintenance handset is overhauled.
After the completion of maintenance, maintenance handset exits all maintenance pressing plates, and each handset other than overhauling handset exits
Maintenance pressing plate corresponding with maintenance handset, each handset normally participate in the logic discrimination of decentralized bus protection.
Specific embodiment is presented above, but the present invention is not limited to described embodiment.The base of the present invention
This thinking is decentralized bus protection handset repair method, it is not limited to the system structure that this method is applied, i.e., not
It is confined to the above-mentioned specific system structure provided, any distributed bus-bar system based on the repair method is the present invention's
In protection domain.Without departing from the principles and spirit of the present invention to embodiment carry out variation, modification, replacement and
Modification is still fallen in protection scope of the present invention.
