Power failure range analysis method and system based on power failure correlation cluster

Abstract

The invention relates to the technical field of power distribution network fault analysis, and discloses a power failure range analysis method and system based on a power failure correlation clustering cluster, and the method comprises the steps: carrying out the clustering analysis of the power consumption data of each user through a K-means clustering algorithm, classifying the power consumption data with the highest similarity into a same cluster group, and carrying out the clustering analysis of the power consumption data with the highest similarity; calculating a power failure correlation coefficient between every two power consumption data in the same cluster, generating a correlation coefficient matrix, determining a corresponding characteristic user, and performing polling of power failure and power consumption states on a transformer area, a feeder line layer connected with the transformer area and other users in the cluster in a multi-level manner by adopting a polling technology based on power failure active alarm of the characteristic user. Therefore, the power failure range can be determined, and the positioning precision of the power failure range of the low-voltage transformer area can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of distribution network fault analysis, in particular to a method and system for analyzing power outage range based on power outage correlation clustering. Background technique [0002] At present, the informatization level on the user side of the distribution network station area is low, the management is chaotic, and there are still shortcomings in the service level of power users. There are generally problems such as inaccurate user power outage information, inability to realize active alarms, and long power supply recovery time. When a fault occurs on the low-voltage side, due to lack of or inaccurate low-voltage wiring information in the station area, power outages in the low-voltage station area mostly rely on user phone reports and emergency repair personnel to investigate door-to-door. . At the same time, the current technical method of installing a large number of monitoring devices on the low-volt...
