Problems solved by technology

[0009] There are some problems in the existing dispatch management system, such as the redundancy of basic data among various disciplines in the horizontal direction, which requires the maintenance of data at the source of the basic data; the poor synchronization of data among vertical dispatching agencies, and the inability to realize automatic collection and wide-area retrieval of data information; data association Poor performance, inflexible and inaccurate data query, etc.

Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0053]Metadata, also known as intermediary data and relay data, is information about the organization of data, data domains and their relationships. In short, metadata is data that describes data, or is used to provide some Structural data for information about a resource. It mainly describes objects such as information resources or data and data attribute information, and is used to support functions such as indicating storage location, historical data, resource search, and file recording. It is also used to identify resources; evaluate resources; track changes in resources during use; realize simple and efficient management of a large amount of networked data; realize effective discovery, sea...

Abstract

The invention discloses a regulation and control cloud power grid model data management method and system based on metadata management. The method comprises the following steps of S1, abstracting anydata in regulation and control cloud power grid scheduling as a data object; S2, performing ID coding on each data object, wherein each data object has a unique ID; S3, establishing a metadata structure table based on the relationship between the data objects; and S4, scanning the information stored in the metadata structure table to realize the full correlation of the data. According to the method, the data is abstracted into the data object, the data object ID coding scheme is innovated, and the ID is used as the management mode of the unique data identifier, so that the data structure is standardized, the data maintenance is standardized, the accuracy is improved, the data quality is greatly improved, and the scientific management is facilitated.

Description

technical field [0001] The invention belongs to the technical field of standardized management of model data in an electric power dispatching system, and in particular relates to a management method and system for controlling cloud grid model data based on metadata management. Background technique [0002] With the rapid formation and development of UHV large power grids, the characteristics of power grids are becoming more and more complex, the transmission and reception terminals, AC and DC are tightly coupled, and the characteristics of grid operation integration are obvious. Dispatch control support means, support business functions such as unified decision-making for regulation and operation, hierarchical control, real-time collaboration, etc. Objectively require grid equipment models and dispatch operation management data to be shared and kept consistent with dispatch agencies above the provincial level to achieve refined management and intelligence decision making. I...
