Application of correlation analysis method in power quality disturbance identification and source assessment
Correlation analysis is a statistical method that can identify correlation patterns between different monitoring points and multi-source heterogeneous monitoring data from power quality monitoring datasets.This method uncovers the inherent operational characteristics of the power grid,making it widely applicable in the field of power quality.First,this paper provides a detailed analysis of the correlation analysis method.Next,it summarizes three main application scenarios of this method in power quality:disturbance identification,disturbance source tracing,and comprehensive assessment.Finally,the paper discusses the applicable conditions for correlation analysis in power quality and presents prospects for its future applications in this field.
