Multidimensional Data Model and Analysis Method of Power Outage Factors in Distribution Network

With the increasing dependence of the customers on the power supply, users are becoming more sensitive for the power outage events, and the proportion of frequent outages is on the rise. This paper established a multidimensional data model of the event of a power outage through the online analytical processing technology (OLAP), the main causes of the power outage in the distribution network and the existing weak link of power supply can be found out from multiple perspectives and the multi-dimensional analysis and mining of power outage data can be realized. The power supply company can take the analysis results to improve the scientific rationality of the route inspection and maintenance plan of the distribution network, and improve the quality of power supply service in electric power enterprises effectively.
