Power transmission and transformation operation and maintenance data quality evaluation method and system

Abstract

In order to solve the problems in the prior art, the invention creatively provides a power transmission and transformation operation and maintenance data quality evaluation method, includes the steps:respectively establishing evaluation models from dimensions such as effectiveness, redundancy, information amount, integrity and accuracy for evaluating the quality of power transmission and transformation equipment operation and maintenance data; establishing a data validity evaluation model based on the invalid ratio; establishing a data redundancy evaluation model based on the repetition rate;establishing a data information amount evaluation model based on the logistic growth model; establishing a data integrity evaluation model based on the relative missing information amount; and establishing an accuracy evaluation model based on a weighted local factor algorithm and the anomaly degree. The invention further provides a power transmission and transformation operation and maintenancedata quality evaluation system, capable of effectively solving the problems that existing data quality evaluation is single and not comprehensive enough, and effectively improving the comprehensive evaluation effect and the evaluation reliability of the power transmission and transformation equipment operation and maintenance data quality.

Description

technical field [0001] The invention relates to the field of data quality evaluation, in particular to a method and system for evaluating the quality of transmission and transformation inspection data. Background technique [0002] With the rapid development of the power grid scale, the capacity of the power grid is continuously expanding, and the amount of inspection data for power transmission and transformation equipment is increasing exponentially. The contradiction between the huge number of equipment and limited manpower will become more and more serious. The main working method can no longer meet the development requirements of intelligent operation and inspection of power grid equipment, and there is an urgent need for intelligent sensing technology to improve the accuracy, integrity and work efficiency of data. [0003] In the era of big data, the inspection data of power transmission and transformation equipment has the characteristics of diversity and richness. Th...
