Comprehensive data quality management method in field of power distribution networks based on three-layer architecture

Abstract

The invention discloses a comprehensive data quality management method in the field of power distribution networks based on a three-layer architecture. The invention relates to the technical field ofpower distribution network data processing. The method comprises a comprehensive data quality management framework of data evaluation, data quality control and visual interaction, and comprises the following steps: firstly, acquiring multi-source data related to a power distribution network through a data evaluation layer, performing data fusion and metadata extraction on the multi-source data, and then performing descriptive statistical calculation and data annotation on metadata; the data quality control layer performs abnormal data detection and correction on the data processed by the dataevaluation layer; and finally, enabling the visual interaction layer to perform visual display and visual analysis on the data acquired by the data evaluation layer, the data processed by the data evaluation layer and the data before and after processing by the data quality control layer. The data quality related to the power distribution network is perfected and improved, meanwhile, the related data of the power distribution network is conveniently managed and monitored, and the problems of power distribution network data characteristics and low generated data quality in the new environment of the current power system are solved.

Description

technical field [0001] The invention relates to the technical field of distribution network data processing, in particular to a comprehensive data quality management method in the distribution network field based on a three-layer structure. Background technique [0002] With the continuous deepening of smart grid and energy Internet construction, the construction of ubiquitous power Internet of Things strategy is proposed, and the deployment and application of power grid dispatching automation system, intelligent operation and inspection system, power distribution automation system, and power consumption information collection system, etc., on the one hand The ability to operate, control, and maintain equipment has been improved. On the other hand, the ability to collect data has also been greatly improved. The distribution and consumption data acquired by power companies have the characteristics of massive, polymorphic, heterogeneous, and high-dimensional . At present, the...
