Research on Automatic Evaluation of Power Quality in Power Supply and Distribution Systems Considering Multi-Indicator Fusion
The evaluation methods for power quality in power supply and distribution systems often focus on individual indicators,resulting in significant discrepancies between the evaluation results and the actual situation.To this end,a method for automatic evaluation of power quality in power supply and distribution systems considering multi index fusion is proposed.This method processes the evaluation indicators of power quality in power supply and distribution systems,standardizes their data,and eliminates the influence between different dimensions.At the same time,this method reduces the dimensionality of the original data through principal component analysis,extracts principal components that reflect the main characteristics of the data,calculates the objective weights of each indicator based on the results of principal component analysis,and automatically evaluates power quality based on indicator weights and thresholds.The results show that this method comprehensively considers the impact of the maximum values of various indicators and can accurately evaluate the power quality of the power supply and distribution system,with good results.
