Abstract

The invention relates to a distribution automation terminal state maintenance method based on a state evaluation grade, and the method comprises the following steps: a state index generation step: obtaining the state quantity data information of a distribution automation terminal, and setting a state index; a state index weight determination step: determining the weight of each state index by using an entropy method; a state index scoring step: scoring each state index according to a preset state index scoring standard; a state evaluation grade determination step: calculating a total score according to the scoring result and the weight of each state index, and determining a state evaluation grade according to a preset total score and state evaluation grade comparison table; and a distribution automation terminal maintenance step: according to the state evaluation grade, adopting a pre-made state maintenance strategy to maintain the distribution automation terminal. Compared with the prior art, maintenance resources can be effectively utilized, and the method has the advantages of objectivity, comprehensiveness, reliability and the like.

Description

technical field [0001] The invention relates to the field of condition-based maintenance of secondary equipment in a distribution automation system, in particular to a method for condition-based maintenance of a distribution automation terminal based on a state evaluation level. Background technique [0002] The distribution automation construction project is the key to building a strong smart grid. As an important intelligent monitoring device in the distribution network, the distribution automation terminal is the key equipment for the safe and stable operation of the distribution network. At present, the condition-based maintenance of distribution automation terminals is still in its infancy, and there is a lack of relevant maintenance strategies and standards. The existing maintenance work is carried out according to the traditional troubleshooting and regular maintenance. The maintenance method of "replacement instead of repair" is often used in troubleshooting, which w...
