1.2.3 Panoramic Modeling Requirements
1.2.3.1 Common Information Model Requirements
The OS2 data center (see the description of some data centers in BRP for details) is constructed with the panoramic model as the core, and the panoramic model design should comply with the "Technical Specifications for the Integrated Power Grid Operation Intelligent System of China Southern Power Grid Part 3: Data Part 6: Panoramic Modeling Specifications "Require.
The panorama model adopts a hierarchical structure and is divided into three parts: the public area, the application area and the extension area for design. The requirements for each partition are as follows:
a) Common Area Model
The panorama model The public area model is extended from CIM, mainly including the modeling of primary equipment and secondary equipment, which is the core of the panorama model, and the definitions of various types should conform to the "Technical Specifications for China Southern Power Grid Integrated Power Grid Operation Intelligent System No. 3" Part: Data Part 5: Power Grid Public Information Model Specification "Requirements. The model in this area contains classes that may be reused by various application modules. The attributes of this class will be expanded uniformly in the public area according to different application requirements, and will not be expanded separately in the application area.
b) Application Area Model
The model of the application area of the panorama model will be modeled separately according to different modules. The model defined in this area takes this module as the source, and is the data model generated during the operation of the module, and is standardized and shared through modeling.
c) Extent model
The panorama model extension area model mainly provides users with a custom extension method for the application area model. When a user needs to extend the model of a module in an application area, the data center should be able to extend the corresponding object or attribute online in the corresponding module in the extension area according to the rules defined in the specification, and provide access to the extended model/data. At the same time, the data center should provide the extension model transfer function, which can transfer the mature extension model to the corresponding module in the application area and encode it.
The OS2 prefecture-level master station data center performs data integration according to the definition of the panorama model, and builds a data center-specific real-time database to provide various real-time/non-real-time data access services through OSB. The data center can store some data, and the other part of the data is still stored by the source module, but through distributed data management, the data center can provide external access services uniformly. The principle of storage solution selection should ensure that the data function of the data center does not affect each source module. running. Among them, the public area model is generally provided by each factory station (direct mining part) or the lower-level OS2 master station (non-direct mining part) through the intelligent remote machine source modeling method, and the model merger is completed through the model splicing module; and can Manual maintenance through the mode management module. The application area model corresponds to each module of the master station side one by one, and can be manually maintained through the mode management module; in addition, it should be possible to expand the lower-level master station application area model by connecting the model at the "panorama model" node in the above figure , and realize model and data sharing through model splicing function and vertical OSB. The extension zone model provides online extension services through the model maintenance function open to users.
1.2.3.2 Encoding and Naming Requirements
Object coding and naming should comply with the requirements of "QCSG 110017.37-2012 China Southern Power Grid Integrated Grid Operation Intelligent System Technical Specification Part 3: Data Part 7: Object Naming and Coding".
In the panoramic model, all objects in the public area and application area should be coded according to the specifications, and the objects in the extension area can be required by the actual application of the functional modules, and the construction unit can decide whether to code or not.
The source of coding includes the intelligent remote machine at the plant station, the panoramic modeling of master stations at all levels, and the object registration center as a technical measure to ensure the standardization of object naming and coding. All global naming and coding must be registered in the object registration center.
The object registration center uses a principle similar to DNS, with a unified interface, but adopts distributed storage of object data vertically, and manages registered objects according to the jurisdiction of each region. For cross-regional object registration, one party is responsible for maintenance, and Synchronized for use by the other party.
1.2.3.3 Modeling scope requirements
From a vertical point of view, the modeling scope of the prefecture-level main station public area should at least include some plants and stations of the 35kV and above main network in the whole region and the distribution network of each voltage level. Part of it should cover 20kV/10kV/6kV medium-voltage feeders, including switch stations, power distribution rooms, section switches, tie switches and other distribution network equipment on the feeders. The prefecture-level main station models are divided into two categories, one is the direct mining factory station, which can be spliced at the main station side after real-time factory station source-side modeling through the intelligent telemotor (factory stations that do not meet the above conditions, temporarily by Modeling at the master station); the other type is the non-direct mining plant station, which can implement model splicing with the provincial master station through vertical OSB.
From a horizontal perspective, panoramic modeling should include the public area with the primary and secondary equipment models of the power grid as the core, and expand the application area model on this basis to form a panoramic model of the power grid that can meet the business needs of the main station.
