# 基于模糊综合评价的大型变压器油质SOH研究Study on State of Health for Large Power Transformer Oil with Fuzzy Comprehensive Evaluation

Abstract: Rational use of transformer oils is inseparable from the evaluation of the health status of the oil quality. The transformer oil testing information is more, and part of the amount of factors exist un-certain characteristics. In this paper, based on the fuzzy comprehensive evaluation method, the mathematical model is constructed to evaluate the status of health for the transformer oil quality. The factor set and the evaluation set are built on the basis of this model. Then the ridge distribution is used as a membership function to establish the fuzzy relation matrix, and AHP method is used to quantify the weight. This paper presents a fuzzy comprehensive evaluation method to analyze oil qualitative health status, and the method is verified by examples. Examples analyses show that this method is reasonable and effective.
