Power distribution network line fault rule mining method and system and storage medium

Abstract

The embodiment of the invention discloses a power distribution network line fault rule mining method and system and a storage medium. The method comprises the following steps: acquiring a power distribution network line fault tripping record, generating a marking event in a power distribution network line fault and reason scene, and generating a power distribution line fault information base; adopting the k-means based data discretization method to cluster each piece of attribute information in a distribution line fault information base to obtain an attribute primary classification set; and performing equal-frequency optimization on the attribute primary classification set, performing fault frequent item set mining on each type of fault attributes in the fault attribute classification setbased on an apriori algorithm, constructing a frequent candidate set, and performing distribution network line fault tripping strong correlation rule screening. According to the technical scheme of the embodiment of the invention, clustering of the fault attributes is realized to mine the fault association rules, and the patrol operation and maintenance range of the power distribution network is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of power system distribution network operation, and in particular to a method, system and storage medium for mining fault rules of distribution network lines. Background technique [0002] As a power network directly facing users, the distribution network has large-scale equipment and wide coverage, and the external environment in which the equipment is located is complex. According to statistics, 80% of the faults in the current power grid are distribution network faults. The related factors that cause the fault tripping of the distribution network include temperature, line length, service life, the number of distribution transformers, and the dynamic operation data of the line. In order to improve the reliability of power supply, it is necessary to inspect the lines in advance. Due to the wide distribution of the distribution network and the large scale of equipment, it is difficu...
