摘要/Abstract

摘要： 为解决变压器状态评估指标具有模糊性和灰色性的问题,将灰色模糊理论应用于变压器状态评估中.建立了变压器状态评估指标体系;采用模糊层次分析法计算指标权重集模部,根据专家经验和信息裕度确定权重集灰部;使用隶属度函数描述评估指标与状态等级的对应关系,以点灰度描述模糊关系的不可信度,建立灰色模糊评判矩阵,对变压器进行了状态评估.通过实例分析,并和其他评估方法进行比较,验证了该方法更加合理有效.

Abstract: As the indicators of transformer condition are fuzzy and gray, we propose an assessment method comprehensively based on gray-fuzzy theory. Firstly, the transformer condition assessment indicators system is established. Then, the weight set is made up of fuzzy part and gray part. Its fuzzy part is calculated based on the fuzzy analytic hierarchy process, its gray part is calculated based on the redundancy degree of information and the experiences of experts. Finally, the subordinating degree function is used to describe the relationship between the data and different levels, the incredibility of fuzzy relation of data is described by the gray. The gray fuzzy judgement matrix is established and the transformer condition is assessed. The example shows that the method can assess the transformer condition effectively and the comparison with other evaluation methods proves that this method is more reasonable and effective.

Key words: transformer, gray-fuzzy theory, fuzzy analytic hierarchy process, condition assessment
