摘要:
合理利用变压器油离不开对油质健康状态的评价。针对变压器油质信息较多,且部分信息量存在不确定性等特点,本文采用模糊综合评价方法,构建了用于变压器剩油质健康状况的评价数学模型。结合该模型并从实际出发,建立了用于变压器油质评价的因素集、评价集,在此基础上,采用岭形分布作为隶属函数来确立模糊关系矩阵,同时利用层次分析方法量化权重,提出了采用模糊综合评价方法来评价油质健康状态,并以实例进行了验证,实例分析表明了该方法的合理性和有效性。

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.
