Problems solved by technology

[0003] Under normal circumstances, the judgment of the aging degree of the power distribution room is generally based on experience alone. In the early days, the design life of the power distribution room did not match the actual operating life. After the power distribution room exceeded the design life, it was still safe. Therefore, the method of judging the aging degree of power distribution room based on experience has limitations and uncertainties

Abstract

The embodiment of the invention discloses a power distribution room aging evaluation method and device, terminal equipment and a storage medium, and the method comprises the steps of building a power distribution room aging evaluation model which comprises first-level indexes and second-level indexes, and determining the subjective weight of each first-level index and each second-level index according to an analytic hierarchy process; determining the objective weight of each secondary index according to the actual survey data of each influence factor of the aging degree of the power distribution room and an entropy weight method; coupling the subjective weight obtained by the analytic hierarchy process and the objective weight obtained by the entropy weight method to obtain a first comprehensive weight of each secondary index; multiplying the first comprehensive weight of each secondary index by the subjective weight of the corresponding primary index to obtain a second comprehensive weight of each secondary index; and solving an aging evaluation result of the power distribution room based on the second comprehensive weight of each secondary index. Through the method, the problem that the aging degree of the power distribution room is not accurately judged only by experience is solved, so that the aging evaluation of the power distribution room is more effective and reasonable.

Description

technical field [0001] Embodiments of the present invention relate to the field of power systems, and in particular, to a method, device, terminal equipment, and storage medium for aging evaluation of a power distribution room. Background technique [0002] With the increasing demand of users, the scale of my country's power grid is also expanding. What comes with it is that when the power grid fails, it will often impact the power distribution room in the distribution network. The aging degree of the power distribution room affects the service life. [0003] Under normal circumstances, the judgment of the aging degree of the power distribution room is generally based on experience alone. In the early days, the design life of the power distribution room did not match the actual operating life. After the power distribution room exceeded the design life, it was still safe. Therefore, the method of judging the aging degree of power distribution room based on experience has li...
