3 do not have a power failure reorganization and expansion
3.1 do not have a power failure reorganization and expansion technical scheme
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, causes the route protection at other intervals of putting into operation to be forced to carry out checking work, in increase workload, complexity
While degree, difficulty, the security risk for the related work that more increased severely, the reorganization and expansion of intelligent substation is set to work than normal station difficulty
Much, it has to arrange " whole station power failure " to coordinate reorganization and expansion work, have impact on production run.
During reorganization and expansion, avoid dress and the technical scheme of expanded scope checking 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, propose that " scapegoat's device " is general
Read, any satisfactory intelligent apparatus is arranged to " scapegoat's device ", and only need configure the line protection, intelligent terminal,
Combining unit is sent to GOOSE, SV service of bus protection, and other services wouldn't use configuration.The debugging efforts of newly-built station also should
Debugging and checking including scapegoat's device Yu bus protection mutual communication.
(2) bus protection, which should possess 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
Overall throw move back soft pressing plate and be set to exit state, such interval is considered as by bus protection to be not present, and is not involved in computing and alarm.
(3) when carrying out the system configuration of reconstruction and extension project, new equipment is upper in the original location to change scapegoat's device, that is, continues to use scapegoat
Device IED titles, MAC Address, the control block title with service and application identities etc., and good all kinds of services are configured, but IED
Description attribute can change.Debugging and later stage, overall throw corresponding to new upper interval is moved back into soft pressing plate (bus protection
On) it is set to input state.
3.2 are modeled based on IEC 61850
Standby spacing modeler model is formed as shown in Fig. 2 concrete methods of realizing is：

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 to bus protection need to be fixed
The data set of device, including the title of data set, the order 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.
The route protection GOOSE data sets of table 1
Step 2：Construction logic equipment
After the function of specifying scapegoat's device, realized for scapegoat's device construction logic equipment class model between multiple logical nodes
Communication.Logical device has merged multiple logical nodes and related service (such as GOOSE, SV service).Logical device is typically 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, directly replaced with new equipment
Body device.According to the standards of IEC 61850, server model can use P2P (Publish-subscribe) patterns or Client-Server (visitors
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, for the reality for the reorganization and expansion work that do not have a power failure in next step
Apply and established theoretical foundation.
