Technical field
The present invention relates to power system automation technology, especially relate to Power System Analysis and simulation technical field.
Background technology
Power grid operation state is fast changing, the highest to requirement of real-time, and active distribution network intelligence degree for a long time
The lowest, reason is just because the emergency reaction ability of system and does not reaches Operational requirements greatly, and that fearness has only to several seconds kinds
Calculating be delayed, be also enough to the impact of electrical network bringing on a disaster property of production system.So the intelligent dispatch of active distribution network is past
Toward being by simulation calculation (actual operation data based on electrical network), the various unusual conditions of simulating grid, it is found for various
The solution of unusual condition, is set in the production system of electrical network in advance.When production system runs into abnormal conditions, the most automatically
It is switched to corresponding solution, thus saves and protect the expensive calculating time, be exactly a kind of method of space for time in fact.
The many scenes of what is called of power industry are concepts being manually set, such as security scenario, abnormal scene and algebra of events
, there is multiple choices scheme in scapes etc., the most polymorphic under each scene.The polymorphic hierarchical relationship such as figure with Simulation Application of many scenes
Shown in 1.Simulation Application needs to revise the parameter of data base when carrying out Power System Analysis with planning, and production system is not fill
Permitted arbitrarily to revise data, so to generate a single data base based on storage facility located at processing plant, be referred to as runing state, analyzed state, planning
State etc..Carry out Power System Analysis and first determine many according to scene (security scenario, abnormal scene and event scenarios) with during planning
State database version, is analyzed in conjunction with creation data, historical data and assistance data and plans.
In prior art, many scenes Multi-state data extracts and the deployment of Simulation Application is all artificial realization, automatization
Degree is the lowest, inefficient, disposes a set of Simulation Application and typically requires one day even time a couple of days.Owing to being accomplished manually workload
Greatly, efficiency is low, is also easy to make mistakes, and because relating to substantial amounts of polymorphic edition data library management, it is easy to cause confusion.
It addition, in prior art, many scenes Multi-state data resource-sharing rate is the lowest, a polymorphic example generally requires exclusive

After C11, event sniffer listen to delete the logout uniquely indicated corresponding to specific polymorphic version to be deleted, delete
Polymorphic version information corresponding with described unique sign in distributed event and state memory cell, and delete the storage of distributed cloud
The specific polymorphic edition data storehouse of unit.
8. according to the management method of the electric power many scenes Multi-state data system described in claim 5, it is characterised in that work as step
When operation described in A is to inquire about all polymorphic versions, step A includes:
A12, application interface unit receive client application instruction；
A22, application interface unit search distributed event and the version querying unit of state memory cell, obtain all polymorphic versions
This information,
Correspondingly, step B includes:
B12, to client application return all polymorphic version informations.
9. according to the management method of the electric power many scenes Multi-state data system described in claim 5, it is characterised in that work as step
When operation described in A is to inquire about specific polymorphic version, step A includes:
A13, application interface unit receive client application instruction, obtain specific polymorphic version to be checked and uniquely indicate；
A23, application interface unit search distributed event and the version querying unit of state memory cell, obtain spy to be checked
Fixed polymorphic version uniquely indicates the polymorphic version information of correspondence；
Correspondingly, step B includes:
B13, to client application return specific polymorphic version uniquely indicate correspondence polymorphic version information.
