POWER CONSUMPTION ABNORMALITY DETECTION METHOD, APPARATUS AND TERMINAL, AND COMPUTER-READABLE STORAGE MEDIUM

WIPO Patent Application WO/2020/006841

A1

A power consumption abnormality detection method, an abnormality detection apparatus, an abnormality detection terminal, and a computer-readable storage medium. The power consumption abnormality detection method comprises: collecting sequence feature values at each target time point from all power consumption time series according to a preset time interval, so as to generate a feature data sequence corresponding to each power consumption time series (S10); performing averaging calculation on sequence feature values corresponding to each target time point in all feature data sequences to obtain an average feature value of each target time point (S20); generating a corresponding average feature sequence from all the average feature values chronologically (S30); calculating a relative entropy between each feature data sequence and the average feature sequence according to a relative entropy algorithm (S40); and if the relative entropy is greater than a preset value, setting the feature data sequence as an abnormal sequence corresponding to the relative entropy (S50). The method improves the accuracy of abnormality detection of power consumption, eliminates the interference of an abnormal value, reduces computational complexity, and improves detection efficiency.
