Abstract

The invention relates to a mixed storage method for distribution and utilization multi-source heterogeneous data. The method includes the steps that the data type of the distribution and utilization data in a target distribution and utilization data source is judged according to the target distribution and utilization data source; the data extraction mode and data storage mode of the distribution and utilization data in the target distribution and utilization data source are determined according to the data type; the distribution and utilization data in the target distribution and utilization data source are extracted from the target distribution and utilization data source according to the data extraction mode of the distribution and utilization data in the target distribution and utilization data source; the extracted distribution and utilization data are stored according to the data storage mode of the distribution and utilization data in the target distribution and utilization data source; data cleaning and conversion are carried out on the stored distribution and utilization data in various distribution and utilization data sources to obtain cleaning and conversion results, and the cleaning and conversion results are stored in the Oracle database. By adopting the scheme, convenience of reading calculation is ensured while achieving storage of mass distribution and utilization multi-source data.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a hybrid storage method and system for multi-source heterogeneous data of distribution and consumption. Background technique [0002] With the construction of smart grids and the application of the Internet of Things, unstructured data and massive time-series data are showing a rapid growth trend. However, the storage and calculation forms of traditional relational databases have been difficult to meet the data storage, real-time query and high-performance computing requirements of the PB (petabyte, a storage unit) level of electric power meters. [0003] The Hadoop architecture is currently the most mainstream storage and computing solution in the field of big data. It greatly optimizes the analysis environment and can provide features such as accurate and fast reports, cross-domain business drivers and dynamic discovery of key indicators. The Hadoop architecture is als...
