Abstract

The invention relates to a power transmission and transformation equipment data quality evaluation method and system, and the method comprises the steps: determining data quality evaluation indexes which comprise data access, accuracy, completeness, consistency and timeliness; quantifying the data access index, the accuracy index, the completeness index, the consistency index and the timeliness index respectively; and determining a quality score of each index according to the quantized numerical value of each index and the weight of each index, and determining the overall evaluation of the data quality according to the quality score of each index. The method is beneficial to improving the accuracy and practicability of data governance.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment operation, in particular to a data quality evaluation method and system for power transmission and transformation equipment. Background technique [0002] With the continuous popularization of information technology applications, more and more attention has been paid to data quality issues in information systems, especially in statistics, management and computer fields. Research on data quality issues began in the late 1960s in the field of statistics, in the early 1980s in the field of management, and in the early 1990s in the field of computers. Research on data quality mainly includes data quality definition and dimension identification, data product manufacturing process, quality measurement and evaluation, and data quality management system. [0003] In terms of data quality definition and dimension identification, foreign researchers believe that the ...
