Abstract

The invention relates to the technical field of data processing and analysis, and discloses an abnormal voltage data detection method and device. The method comprises the steps: firstly, obtaining original voltage data and carrying out per-unit processing to make attributes of the original voltage data converted into dimensionless numerical attributes, and determining a to-be-measured voltage data set; then, acquiring to-be-measured voltage data attributes in one-to-one correspondence with all pieces of to-be-detected voltage data, and determining a to-be-detected voltage data attribute set; further mining association rules in the to-be-detected voltage data attribute set according to the definition of function dependence and in combination with topological structure information of the power distribution network, and determining an abnormal data discrimination rule; and finally, judging whether each to-be-detected voltage data attribute meets the abnormal data judgment rule or not, and judging the to-be-detected voltage data corresponding to the to-be-detected voltage data attribute which is not met as abnormal data. By mining the association rules in the attribute set of the to-be-detected voltage data, effective abnormal data detection can be performed on the voltage data in the power distribution network voltage monitoring system.

Description

technical field [0001] The present application relates to the technical field of data processing and analysis, in particular to a method and device for detecting abnormal voltage data. Background technique [0002] With the digital transformation of society, the popularization of informatization, and the rapid development of various advanced IoT sensor technologies, the scale of power data is growing at an alarming rate. Power data includes voltage data, power sales data, transaction power price data, and power user data, etc. These power data will be stored in the corresponding power system, and each power data has broad application prospects. [0003] The power system includes a distribution network voltage monitoring system, where the voltage data in the power data is stored in the database of the distribution network voltage monitoring system. If the stored voltage data can be deeply excavated and researched, it can bring strong technical support to power consumption pr...
