This method for detecting and locating deviations in coal mine electric energy metering system in-volves forming a network topology based on a tree structure,calculating real-time data such as current,volt-age,power,and electricity consumption to generate a deviation detection correlation dataset,obtaining the sam-ple standard deviation and correlation coefficient of metering nodes and their child nodes,and determining de-viations in the electric energy metering system and accurately locating the deviating electric energy metering devices through the analysis of sample standard deviation and correlation coefficient.This method can up-grade the current electric energy metering system,effectively addressing the issues of difficult detection and inaccurate localization of deviations.
