Abstract

The invention discloses a power distribution network fault diagnosis method and system, and relates to the technical field of power distribution networks, in particular to a power distribution network fault diagnosis method and system. The method comprises the following steps: obtaining target power grid data; analyzing the target power grid data and a preset key feature set to obtain a key feature value; classifying the key feature quantity to obtain preliminary fault data; screening the preliminary fault data to obtain target fault data; and analyzing the target fault data to obtain target power grid operation state data. The target fault data is screened from the numerous data, and the target fault data is analyzed to obtain the power grid operation state data, so that the power grid operation state is visually fed back to a user, the user can quickly identify a power grid fault state, and the technical problem that the running state of a power distribution network cannot be obtained in time due to huge and complex data in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to a fault diagnosis method and system for a distribution network. Background technique [0002] With the development of intelligent power distribution technology, the traditional passive power grid has evolved into an active distribution network including distributed power sources, and with the development of distribution network automation, there are more and more types of power supply equipment in the power grid. Data and information materials are becoming more and more complex, and the amount of data collected by terminal acquisition devices in the distribution network is increasing exponentially. [0003] Data statistics require many planners to carry out statistics and analysis. Due to the large amount of data and many models in the distribution network, the operation and maintenance personnel have a large workload and a long period of statistical analysis, and it...
