Problems solved by technology

However, the information managed by CIM is complicated. There are 257 classes in the IEC61970 CIM standard (CIM10_030501), and there are thousands of related attributes, and this is only the objects involved in scheduling operation, plus the objects in asset management and operation. , a larger variety of data
At the same time, the common information model (CIM) i

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] see figure 1 , a kind of grid enterprise integrated information model metadata management method of the present invention, comprises the following steps:

[0023] Step A: Maintain metadata in the data dictionary.

[0024] Step B: Automatically establish the relationship between the model storage table and the model storage table according to the metadata.

[0025] Step C: When importing model data, query the metadata to determine whether the structure of the metadata is the same as the structure of the model data to be imported. If they are the same, store the model data into the database according to the metadata.

[0026] Step D is also included after the step C: the metadata management can export the metadata into a model structure file. In the step B, the model storage table is automatically established, and the metadata management syste...

Abstract

The invention relates to a metadata management method of a power grid enterprise integrated information die, which comprises the following steps of: A. maintaining metadata in a data dictionary; B. automatically establishing a relationship between every two die storage tables based on the metadata; and C. inquiring the metadata when introducing die data, judging whether a structure of the metadata is the same with a structure of the die data to be introduced, and if yes, warehousing the die data based on the metadata. The invention relates to the metadata management method based on a CIM die of IEC, and a data interface accords with a universal standard because the CIM die of the IEC is adopted. The adopted metadata management method can ensure automatic variation of the die table and the structure ability along with the variation of the metadata and keeps flexible configuration of a database structure. A database table structure accords with a power industry standard to provide a feasible way for solving the problem of power enterprise information integration.

Description

technical field [0001] The invention relates to a data management method, in particular to a metadata management method for an integrated information model of a power grid enterprise based on an IEC CIM model by configuring metadata to automatically generate a model table to maintain a flexible configuration of a database structure. Background technique [0002] At present, with the improvement of informatization in electric power enterprises, a large number of comprehensive distributed application systems have been built. These systems may use different computer platforms, different database technologies, and different information expression support tools to complete their own functions. However, The systems cannot be well interconnected, which is mainly manifested in the systems at the same level. These separate subsystems are responsible for different functional contents in the system, and there is almost no information exchange between them, which hinders the overall syst...
