摘要

在传统的变压器状态评价方法中

常权无法客观反映变压器部分参数偏离正常值时对整体评价影响。基于此

笔者提出了基于变权重的变压器模糊综合状态评价方法。首先采用层次分析法确定变压器各影响因素指标的权重

然后考虑实际情况对各影响因素权重进行变权处理

减少评价的主观性

使变压器的状态评价结果更为合理。应用文中方法对实际变压器进行状态评价

验证了该方法的合理性和可行性。

Abstract

In the traditional evaluation methods of transformer condition

constant weight value is unable to objectively reflect the impact of deviation of some parameters on the evaluation. Therefore

a fuzzy synthetic evaluation method of transformer condition with variable weight value is proposed in this paper. The analytic hierarchy process is adopted to determine the weight value of each influencing factor index of a transformer

then the practical condition is considered to deal with the basic weight values of all influencing factors. The proposed method weakens the subjectivity of evaluation and make evaluation result of transformer condition more reasonable.The condition evaluation of an real transformer validates the feasibility of the proposed method.
