1, model cloud system architecture and expansion system
Model cloud system structural framing is divided into three class roles with the server node of the whole network scheduling model at different levels system: management server, model service device and client.Management server is management node, and the metadata of memory model system (model area under one's jurisdiction sign, model service device and standby server position thereof, model version sign, the information such as model file storage directory) is responsible for the management of model service device information; The model service device is responsible for the storage of area under one's jurisdiction model data or the storage of redundant area under one's jurisdiction model, and provides the area under one's jurisdiction model relevant service interface and other local model service interfaces; Client provides the access interface of application program, and provides with the form of service.The client models service interface possesses the model service device situation of returning according to management server, the functions such as merging of the decomposition of execution model access task and return results collection.Client is at first obtained the information of model service device alternately with management server, carry out Task-decomposing, and specific tasks are finished the data storage with the model service device again.Because only there are control stream in client and management server, and only there is data stream in the model service device, and the volt that can greatly reduce management server exists, and so that the highly-parallel work of system, and then the overall performance of raising system.
2, the storage of the data of model cloud and maintenance
The model service device is responsible for model cloud data storage and maintenance.Model data in the model cloud is divided three classes: area under one's jurisdiction model, real-time model, application model.Safeguard that the whole network model is commonly referred to as and safeguard the area under one's jurisdiction model, on the model service device of the storage of area under one's jurisdiction model profile formula and the whole network, jointly consist of the whole network model.Real-time model refers to the electric network model of the scheduling institution real-time system use at model service device place, and it is comprised of the online model of Real-time external network equivalence model and area under one's jurisdiction that the higher level provides.Application model is that certain grade of scheduling institution is in order to satisfy application demand, the privately owned model of the application of foundation.
The file layout of model exists for two classes: model bank and CIM/E data format file.Model bank storage area under one's jurisdiction is safeguarded states model or for application provides execution environment, is online, historical, the main store and management form of following attitude area under one's jurisdiction model based on CIM/E form model file.
3, the unified of large electric network model safeguarded and dissemination method
The version identifier of large electric network model should be the combination sign that comprises each area under one's jurisdiction model version sign of Grading And Zoning.Can obtain more than the online large electrical network electric pressure or the version information in certain grade of certain district by model management servers at different levels.Current issue model is the set that management servers at different levels are specified the online version area under one's jurisdiction model of master cast server stores.Model service devices at different levels provide the model data of this administrative area, and the area under one's jurisdiction model version of management scheduling at the corresponding levels.
The user according to authority in the distributed maintenance of safeguarding implementation model data on the attitude database of the whole network, by making up area under one's jurisdiction test states model, after building the test environment checking, Maintenance Model drops into online, generate based on the online model version in the area under one's jurisdiction of CIM/E file on the model service device, and test model is synchronized to real-time system.The real-time states model of conduct of model service device storage test model.
Management server detects the variation of higher level, peer's (comprising the corresponding levels), subordinate's management server area under one's jurisdiction model version; When dropping into, master cast server area under one's jurisdiction model version notify management server at the corresponding levels, management server at the corresponding levels to notify higher level, peer, subordinate's management server.The model service device provides service to realize: obtain up-to-date external network equivalent model and local maintenance model that higher level's model service device generates for this area under one's jurisdiction, generate the test states model; The area under one's jurisdiction that provides according to real-time states model and subordinate's model service device is the Equivalent Model that subordinate's model service device generates the area under one's jurisdiction at line model, and the model management server is stored up-to-date Equivalent Model for each subordinate's scheduling.The version identifier of test states model and the version identifier of real-time states model are consistent with large electric network model version identifier.
4, model cloud model version management
Model service device node supply a model version management and relevant service interface.
Model version is divided three classes: area under one's jurisdiction model, real-time model, application model.
The model version memory contents comprises: Description of ××× (Release name) file, CIM-E form model file, also will comprise corresponding CIM-G format graphics file and communication point table according to release type, the Description of ××× (Release name) file should record rise time, the whole network model version sign of this version, release type.The model service device is realized vertical time dimension and is laterally used the model management of dimension.Should adopt the mode of full model and incremental model combination for the storage of model and graph data.
5, model cloud service interface
The model cloud system adopts the service of architecture (management server, model service device, client) the implementation model cloud of SOA.Client provides the client embedded interface, management server supply a model server, and the management information of model version, and the model service device is realized the concrete operations such as concrete model maintenance, model access, model subscription, model version management.
What need statement is that content of the present invention and embodiment are intended to prove the practical application of technical scheme provided by the present invention, should not be construed as the restriction to protection domain of the present invention.Those skilled in the art can do various modifications, be equal to and replace or improve inspired by the spirit and principles of the present invention.But these changes or modification are all in the protection domain that application is awaited the reply.
