Abstract

The invention relates to a distribution network equipment group state evaluation method, device and system and a computer storage medium, and the method comprises the following steps: building a second-level evaluation index set corresponding to a to-be-evaluated equipment group, and building a comprehensive first-level index corresponding to the second-level evaluation index set; establishing andprocessing a directed relation matrix corresponding to the second-level evaluation index set to obtain a second-level index importance degree value corresponding to each second-level evaluation index; establishing a lambda fuzzy measurement model based on the importance degree value of each secondary index; obtaining fuzzy measure values corresponding to the secondary evaluation indexes accordingto the lambda fuzzy measure model; and obtaining a first-level index evaluation value corresponding to the to-be-evaluated equipment group according to each fuzzy measure value and each preset second-level index score value. According to the invention, equipment group division is carried out on the distribution network equipment and state evaluation is carried out on the equipment group by usingthe fuzzy measure, so that single-machine troubleshooting is avoided, the workload is reduced and the state evaluation efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of distribution network state evaluation, in particular to a distribution network equipment group state evaluation method, device, system and computer storage medium. Background technique [0002] As the terminal link between the power system and the user, the distribution network has a direct impact on the overall efficiency of the system and the quality and reliability of the user's power consumption. Most of the user's power outages are caused by the failure of the distribution system. There are a large number of distribution network equipment and scattered geographical locations; equipment states are diverse, there are many state parameters, and the evaluation workload is large. Their operating status has an important impact on the reliability of power supply. Therefore, it is necessary to evaluate the status of distribution network equipment. [0003] During the implementation process, the inv...
