Cluster Analysis Method for Reliability of Circuit Breakers in Low-voltage Distribution Systems
The time of user power outage is not regular,and different types of circuit breakers have different performance characteristics and failure mechanisms.To accurately analyze the reliability of low-voltage distribution systems,a reliabili-ty clustering analysis method for low-voltage distribution system circuit breakers is proposed.Collect performance degra-dation data of low-voltage distribution systems during long-term operation,combine the low-voltage distribution system partition model,divide the sample space of performance degradation data,introduce clustering algorithm,establish a coarse clustering label matrix,process performance degradation data samples in an orderly and informational manner based on graph regularization constraints,design unlabeled performance degradation data clustering,obtain reliability a-nalysis indicators of low-voltage distribution system circuit breakers under interference factor graph regularization con-straints,and perform equivalent processing to determine the reliability of low-voltage distribution system circuit breakers.The experimental test results show that whenthe anchor numberis set to 35 and the regularization coefficientis 101.5,the normalized mutual information and clustering purity of the clustering results tend to stabilize.The reliability clustering a-nalysis method for circuit breakers is practical and applicable.
