Abstract
The operation state assessment of dry-type transformers mainly depends on various parameters such as temperature, humidity, voltage and current acquired by on-line monitoring. This paper presents a synthetic evaluation model for dry-type transformers based on fuzzy analytic hierarchy process (FAHP). First, 16 basic factors are selected to establish evaluation index system. The index constant weights are determined based on FAHP. Then, the index variable weights are evaluated by the balance function of the variable weight theory, by which the constant weights are modified according to the level that the factor deviates from the normal data. And then, a comprehensive assessment for operation situation of dry-type transformers is illustrated with the established multi-layer fuzzy evaluation method. The practical application shows that synthetic evaluation for dry-type transformers' condition based on FAHP is valid and reasonable, which can give an effective theoretical support for the change from planned maintenance to condition-based maintenance.关键词
