Analytic hierarchy process-based power data quality evaluation model construction method

Abstract

The invention discloses an analytic hierarchy process-based power data quality evaluation model construction method. The method comprises the steps of constructing an analytic hierarchy process-basedquality evaluation model of power data in a metering automation system; acquiring electric power data in the metering system, and determining a corresponding data quality evaluation object; selectingand accurately defining evaluation dimensions according to requirements of data quality evaluation; designing evaluation rules of different dimension indexes in combination with different metering data object business calculation rules; combining metering business reality, fully applying expert experience, constructing a judgment matrix to determine the weight of each evaluation index, and endowing each evaluation index with an expected value; and running the configured evaluation rule for evaluation, and calculating a data quality score according to the qualified percentage. According to themethod, the mass data in the metering automation system can be accurately and effectively evaluated, the hidden danger that the power data quality is reduced is discovered in time, and the managementlevel of a power grid company on the power data quality is improved.

Description

technical field [0001] The invention relates to a method for constructing an electric power data quality evaluation model based on an analytic hierarchy process, and belongs to the technical field of electric power data management. Background technique [0002] With the rapid development of new-generation information technologies such as big data, cloud computing, and the Internet of Things, the high degree of integration of the ternary world of humans, machines, and objects has led to explosive growth in data scale and highly complex data models.
