基于改进灰靶理论的油纸绝缘状态评估
Evaluation of Oil-paper Insulation Condition Based on Improved Grey Target Theory
摘要
Abstract
The improved grey target theory is applied in the research of transformer oil-paper insulation aging state.First the data are measured by recovery voltage method and relative parameters are identified by equivalent circuit of ED,using extracted parameters as the characteristic quantity of assessment of oil-paper insulation aging state.Second,because of the different influence of several characteristic quantities on oil-paper insulation aging state,the improved AHP method and entropy weight method is used in the weight distribution of these characteristic quantities.Last,the data of transformer are collected and grades of oil-paper insulation aging states are calculated.Experimental results show that this method can effectively and reasonably evaluate the transformer oil paper insulation aging status and provide a reference for the transformer condition maintenance.关键词
