[0002] Research on power reliability mostly focuses on proposing new reliability indicators and calculation methods of indicators, and now a mature index system and evaluation method have been formed; in terms of reliability application and management, the current power supply reliability management of domestic power companies The system collects a large amount of power outage event data, and records every power outage event in the distribution network in detail, covering the responsible department, power outage time, equipment where the power outage occurred, responsibility reasons, technical reasons, power outage scope, protection actions, etc.; However, for a long time, the role of these large power outage event data is limited to the statistics of various distribution network reliability indicators and used for the assessment of each unit, but lacks the means to analyze and mine its deep-seated laws, which has virtually caused data corruption. Waste, but also bound the improvement of the reliability of my country's power distribution system;

A method for mining weak links in the reliability of power distribution systems based on multi-dimensional analysis. It includes data collection and sorting of power outage events in distribution network, CUBE modeling of power outage event data in distribution network, CUBE reconstruction of outage event data based on mining targets, single-dimensional analysis of outage event data on CUBE, and multi-dimensional comprehensive analysis on power outage event data on CUBE. and so on. The invention breaks through the limitation that the power failure event data is only used for reliability index statistics in the traditional distribution network reliability management, establishes a multi-dimensional model for the power failure event data itself to analyze, and excavates the weak reliability of the power distribution network from multiple angles and different levels. It can effectively discover the regular characteristics of the influencing factors of power outage events in the distribution network and the weak links in the reliability of the distribution network. The management unit provides valuable decision-making basis.
