All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a first step of a method for compiling an over-planned power utilization limit circuit modification table according to an embodiment of the present invention, which may specifically include the following steps:
step S101, analyzing graph-model data of a power distribution network area to be analyzed to obtain corresponding graph-model parameters; the graph model data is obtained from a preset equipment center; the graph model parameters are used for constructing a target database;

In the embodiment of the invention, GIS graph-model data is obtained from the power distribution network to be analyzed, and the file data contains the detailed equipment information of the 10kV line and the connection topological relation between the equipment. And exporting CIM files from the graph model data according to a preset CIM exporting rule, analyzing the CIM files by adopting a prefabricated CIM structure template so as to obtain equipment parameters corresponding to the equipment model data and connection parameters corresponding to the connection point model data, and taking the CIM files, the equipment parameters and the connection point parameters as a data base established by a target database. And the target database comprises various tables such as a transformer information table, a switch information table, a line conductor information table and the like which are sorted, and topological relation information of the equipment is obtained after the connection relation of various equipment is analyzed.
In a specific implementation, the device parameters corresponding to the device model data and the connection parameters corresponding to the connection point model data include detailed description items of element type labels (devices such as transformers and cables or graphic model connection points) of the CIM file, relative to the element code of the CIM file.
It should be noted that GIS refers to a Geographic Information System (GIS), which is a technical System for collecting, storing, managing, computing, analyzing, displaying and describing Geographic distribution data in the whole or a part of the space of the earth's surface layer (including the atmosphere) under the support of a computer hardware and software System. The method has strong spatial information analysis and spatial topology modeling capabilities, and is enabled to be based on natural advantages in the application of power distribution network topology analysis.
The CIM (common Information Model) is based on ICE61970/IEC61968 standard, is used for describing a conceptual Model of management Information, and can provide standards and applications for Information inheritance and interaction contribution between management systems in a store. One of them is used to describe the management information and the conceptual model, independent of the specific implementation. CIM is divided into two parts: CIM Specification (CIM Specification) and CIM Schema (CIM Schema). The CIM specification provides a formal definition of the model, which describes the language, naming, meta-schema, and mapping techniques to other management models (e.g., SNMP MIB); the CIM mode gives a description of the actual model. The CIM model is composed of a core model, a public model and an expansion model. The core model is a set of classes, connections and attributes, the set of objects providing a basic information model common to all administrative domains: the common model provides a common information model for specific administrative domains, such as systems, applications, networks, devices, etc.; the extension model represents a technology-specific extension of the generic model.
Through CIM modeling, the idleness and representation of entities in the management domain, including their attributes, operations and relationships, can be derived. Such a model is independent of any specific database, application, protocol, and platform. Therefore, the CIM model requires that different platform-based applications provided by different developers all describe management data in a standard format to enable data sharing among multiple applications. CIM adopts an object-oriented mode to construct a new structure and conceptual model suitable for a management system and a network. CIM modeling is a general method. CIM modeling of a specific management domain is extended on the basis of a core model and a common model.
