Problems solved by technology

The traditional power grid operation data platform can no longer meet the needs of enterprise operation data storage optimization and parallel processing
The traditional data storage structure is intuitive, but its significant disadvantage is the large amount of data redundancy
The operation information is stored repeatedly, which brings certain difficulties to the fusion operation between different operation data tables, resulting in low query efficiency of operation data

Abstract

The present invention provides a high-efficiency data cleaning and conversion method based on CIM. The method includes: receiving a data cleaning and conversion task requested from a power system user; interpreting the data cleaning and conversion task into a workflow diagram; converting the workflow diagram and Optimizing, executing the cleaning conversion task based on the optimized workflow graph. The present invention proposes a high-efficiency data cleaning and conversion method based on CIM. With the support of the improved power grid operation data model and the distributed data platform, the source data is extracted, cleaned, and integrated to ensure data quality and reliability. The unified standard data output of the database has wide applicability to support cluster deployment and concurrent computing, and can provide reliable support for grid data automation integration and analysis.

Description

technical field [0001] The invention belongs to the field of big data mining and information retrieval, and in particular relates to a CIM-based efficient data cleaning and conversion method. Background technique [0002] With the wide application of various power transmission and transformation equipment, the amount of power grid operation data has shown geometric growth. For the rapid analysis and processing of massive operating data and the detection and mining of abnormal data, the challenge is how to perform effective data processing and efficient data analysis on the big data of power grid operation. Due to the large differences in the software and hardware systems and resources of companies in various network provinces, it is more difficult to build a data online analysis platform. The traditional power grid operation data platform has been unable to meet the needs of enterprise operation data storage optimization and parallel processing. The traditional data storag...
