Power distribution network line fault rule mining method, system and medium of frequent item set

Abstract

The embodiment of the invention discloses a power distribution network line fault rule mining method, system and medium of a frequent item set. The method comprises the following steps: collecting a power distribution network line fault tripping record, and generating a mark event under a power distribution line fault and reason scene; generating a power distribution network line information base containing multiple attribute information according to the mark event; based on an apriori algorithm, performing fault frequent item set mining under different fault reason scenes, and constructing the frequent item set covering different frequent attribute numbers; and performing power distribution line fault tripping strong-related rule screening based on the power distribution line fault information base according to the frequent candidate set. Through the technical scheme disclosed by the embodiment of the invention, the existing power distribution fault sample data is integrated with the frequent item set data mining method, thereby mining a fault association rule, reducing the power distribution network patrolling operation and maintenance range, and solving the problem that the patrolling and overhauling charge of the whole region line of the existing power distribution network and the equipment is huge.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power system distribution network operation, and in particular to a method, system and medium for mining distribution network line fault rules of frequent itemsets. 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, and the number of distribution transformers. 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, without fault assistance strategies, the inspect...

Problems solved by technology

In order to improve the reliability of power supply, it is necessary to conduct inspections on the lines in advance. Due to the wide distribution of the distribution network and the large scale of equipment, without fault assistance strategies, the inspection and maintenance of all regional lines and equipment will cost a lot

[0003] Therefore, the problem of huge inspection and maintenance costs for all regional lines and equipment of the existing distribution network needs to be solved urgently
