Embodiment Construction

[0023] Data modeling method based on power information:

[0024] Refer to attached figure 1 , the power information data is structured according to the physical dimension of the data subject, the index application dimension and the time dimension, and the label management is carried out on each dimension label according to the power information hierarchical rule base, and the three-dimensional positioning management of the power information data (physical dimension, application dimension, time dimension) to establish a structured storage and control mode for three-dimensional positioning power information data.

[0025] The main purpose of modeling and controlling power information data:

[0026] 1) Unify the power information data structured storage standard;

[0027] 2) Atomize power information data according to the smallest unit;

[0028] 3) On the basis of the atomic processing of electric power information data, hierarchical coding and identification are carried out a...

Abstract

The invention discloses a method for modeling on basis of power information data and applying metadata management. The method comprises the following steps of: establishing a power information main body coding and application index coding rule base first; constructing a structured power information data storage mode in a database according to a physical dimension, an application index dimension and a time dimension of the main body, and according to coding rules, marking the physical dimension, the application dimension and the time dimension on the structured data to form power information statistical analysis service application-oriented modeling data. The modeling data is managed and defined by using a power information application-oriented metadata management technique which realizes application of a main body metadata management method and application of an application index metadata management method. The method solves the problem of performing atomization and structuring treatment on the power information service data in practical application, and realizes a basic data model for standard storage of the power information.

Description

technical field [0001] The invention belongs to the technical field of electric power information management, and relates to a data modeling and metadata management application method based on electric power information. Background technique [0002] With the development of power system automation, informatization and interactive technology, the massive characteristics of power information have become increasingly prominent, covering all aspects of power dispatching, trading, finance, production and operation, and office business. How to effectively build a unified standard power information data storage structure, how to effectively count, analyze and mine power information data in various business systems, and how to support users to effectively use business data through flexible platform tools have become problems that plague various Bottleneck problem for users of electric power information business system. In addition, with the continuous emergence of various business-...
