Replacement Priority Assessment Model of Distribution Transformer
摘要
Abstract
To solve the problem of replacement priority assessment model of distribution transformers,we propose an assessment model for multi-level distribution transformer replacement priority,including the establishment of the evaluation system and presentation of corresponding calculation method.This model is based on fuzzy analytical hierarchy process and grey fuzzy comprehensive evaluation,and it covers different kinds of assessment factors.Firstly,a fuzzy analytical hierarchy process is adopted to establish the multi-level analysis model and determine the weight of different kinds of factors.The grey of the weight is calculated by considering the expertise,which is used to describe the abundance of information,then the weight matrix is established.Secondly,the deterioration function is used to process the different magnitude data and the membership function is used to describe the relationship between the data and different levels.Grey is adopted to describe the abundance of the data,then a grey fuzzy matrix is established.Finally,the weight matrix and the grey fuzzy matrix are synthesized to get the comprehensive assessment results.The calculation shows that the model takes multi-factors into consideration and improves fuzziness and grey of data.It can evaluate the transformer replacement order reasonably,and provides a kind of reference for the economic operation of distribution transformers.关键词
