Embodiment 1

[0071] A description method for multi-source heterogeneous data in the field of power grid regulation and control of the present invention, see figure 1 shown, including the following steps:

[0072] Step S1: By describing the data source type, data source name, and data source version information of multi-source heterogeneous data, a data source information description item is formed.

[0073] The data source may be a database, or any system platform that provides data, which is not limited. Such as figure 1 As shown, business applications such as big data analysis and mining can obtain multi-source heterogeneous data from the database through the data read-write service for front-end display and data analysis processing, and can also write the data to be stored into the corresponding database through the data read-write service, and then Realize data exchange and sharing.

[0074] In this embodiment, it is assumed that the source of multi-source heterogeneous data in the ...

Abstract

The invention discloses a method for describing multi-source heterogeneous data, which comprises the following steps of describing data source information of the multi-source heterogeneous data to form a data source information description item; describing metadata information of the multi-source heterogeneous data, and forming metadata information description items; describing data of the multi-source heterogeneous data to form a multi-dimensional data description area; and sequentially combining the data source information description item, the metadata information description item and the multi-dimensional data description area to obtain a complete multi-source heterogeneous data description. According to the multi-source heterogeneous data description method, self-description, self-check and expandability of the multi-source heterogeneous data description method are achieved by describing data source information and metadata information; multi-level nested complex data structure storage is supported through a multi-dimensional data grid and a hierarchical description method.

Description

technical field [0001] The invention belongs to the technical field of electric power control, and specifically relates to a description method and device for multi-source heterogeneous data in the field of power grid control, and also relates to an analysis method and device for describing multi-source heterogeneous data generated by the above description method. Background technique [0002] With the rapid expansion of the smart grid construction and the business scope of the power grid regulation system, the number of data sources has increased, the types of data have been diverse, and the scale of data has increased sharply. The power industry has entered the era of big data. The application prospect of electric power big data is broad, but it faces problems such as scattered data, multiple types of data sources, and inconsistent data structures. [0003] In the power dispatching control system, business applications in the field of power grid control aim at data stored ...
