3 do not have a power failure reorganization and expansion
3.1 do not have a power failure reorganization and expansion technical solution
In intelligent substation reorganization and expansion works, because needing to bus protection (by taking 220kV double bus scheme situations as an example)
The lower dress of configuration is performed, the route protection at other intervals of putting into operation is caused to be forced to carry out verification work, is increasing workload, complexity
While degree, difficulty, the security risk for the related work that more increased severely makes the reorganization and expansion of intelligent substation work than normal station difficulty
Much, it has to arrange " whole station power failure " cooperation reorganization and expansion work, affect production run.
During reorganization and expansion, avoid dress and the technical solution of expanded scope verification under unnecessary bus protection as follows：
(1) the transformer substation system configuration (SCD configurations) during newly-built station by considering together on long term all line segregations.For still
The intelligent apparatus (route protection, intelligent terminal, combining unit) for not building line segregation of non-type selecting proposes that " scapegoat's device " is general
Read, any satisfactory intelligent apparatus is set as " scapegoat's device ", and only need configure the line protection, intelligent terminal,
Combining unit is sent to GOOSE, SV service of bus protection, other services wouldn't use configuration.The debugging efforts of newly-built station also should
Debugging and verification including scapegoat's device Yu bus protection mutual communication.
(2) bus protection, which should have to be spaced integrally to throw, moves back soft pressing plate.Before newly-built station puts into operation, line segregation is not built for all
Whole throw move back soft pressing plate and be set as exiting state, such interval is considered as by bus protection to be not present, and is not involved in operation and alarm.
(3) when carrying out the system configuration of reconstruction and extension project, new equipment is upper in the original location to replace scapegoat's device, that is, continues to use scapegoat
Device IED titles, MAC Address, the control block title for having matched service and application identities etc., and good all kinds of services are configured, but IED
Description attribute can change.Debugging and later stage will move back soft pressing plate (bus protection corresponding to new upper whole throw being spaced
On) it is set as input state.

Determine which function of scapegoat's device needs to carry out data exchange with other intelligent apparatus, then by each data exchange that needs
Function Decomposition is logical node (LN).
To avoid filling under bus protection after the completion of reorganization and expansion, the intelligence that GOOSE, SV information are sent out to bus protection need to be fixed
The data set of device, the title including data set, the sequence and quantity of data set member.Such as route protection is sent to after fixing
The GOOSE data sets of bus protection are as shown in table 1.
1 route protection GOOSE data sets of table
Step 2：Construction logic equipment
After the function of specifying scapegoat's device, between the multiple logical nodes of scapegoat's device construction logic equipment class model realization
Communication.Logical device has merged multiple logical nodes and related service (such as GOOSE, SV service).Logical device is generally wrapped
Include three logical nodes：The one logical physical equipment (LPHD) for representing facility information and health status；One provides GOOSE controls
The logical node 0 (LLN0) of the communication services such as clamp dog, SV control blocks；N number of logical node (LN) comprising concrete function.
Step 3：Establish server model
Scapegoat's device is modeled as a server model, during later stage reorganization and expansion, is directly replaced with new equipment
Body device.According to 61850 standards of IEC, P2P (Publish-subscribe) patterns or Client-Server (visitors can be used in server model
Family end-server) pattern, so as to the transmitting of GOOSE information and SV information between complete intelligent apparatus.
By " do not have a power failure reorganization and expansion strategy " to reduce the hourage that has a power failure during reorganization and expansion at a specified future date, while avoid other throwings
Fortune interval repeats verification experimental verification, reduces workload and O＆M complexity, the reality for the reorganization and expansion work that do not have a power failure in next step
It applies and has established theoretical foundation.
