Embodiment Construction

[0024] Hereinafter, the present invention will be further described in detail with reference to the drawings and examples.

[0025] Such as figure 1 As shown, the overall framework of the holographic time scale measurement data extraction and conversion of the present invention is divided into three levels, from bottom to top, respectively, the resource layer, the analysis layer, and the management layer. Each layer is composed of several blocks, and each block represents a meta-model.

[0026] Among them, the resource layer describes the metadata model of various different types of data resources. The metadata refers to the abstract information of the data, and here mainly refers to the holographic time scale measurement data. The analysis layer defines the further description and various rules of the model in the resource layer. It is the most critical part of the data extraction framework model, including the extraction, transformation and loading of the meta-model. The extract...

Abstract

The invention discloses a power-grid-operation-oriented holographic time scale measurement data extraction conversion method, and belongs to the technical field of a database. According to the method, firstly, the holographic time scale measurement data extraction is carried out; then, the holographic time scale measurement data conversion is carried out; finally, the holographic time scale measurement data loading is carried out; and the holographic time scale measurement data is integrated with power grid models stored in a relational database and various other kinds of service data. The method has the advantages that data extraction conversion can be carried out in the field of holographic time scale measurement data processing; the effective extraction, cleaning and conversion are realized; the cost and the complexity degree of subsequent application development are greatly reduced; the total size of the data can be reduced; the quality of the data can be improved; function modules of the conventional system are effectively extracted and utilized; efficient up-application is realized on the premise of not influencing the functions, safety and stability of the conventional system; the value of the conventional system is sufficiently found; automation and intellectualization of the power grid operation processing are realized at a higher level; and the safe and stable operation of a power grid is guaranteed.

Description

Technical field [0001] The present invention belongs to the technical field of database, and more precisely, the present invention relates to a method for extracting and converting holographic time scale measurement data for power grid operation. Background technique [0002] With the continuous expansion of power grid construction and the deepening of research and application of smart grids and smart substations, dispatch automation systems face more and more collection points. Significantly different from previous regional dispatch automation systems is that the scale of data collection faced by large-scale regional power grid dispatch automation systems has risen sharply, and individual regions will reach the scale of millions of collection points, and the scale of data storage will shift from the current GB level to TB level. In addition, with the continuous improvement of the dispatch automation level, various business systems have put forward higher requirements on the disp...
