【摘要】 为了提高评估指标权重的合理性,实现电力变压器剩余技术寿命的合理预测,采用三标度法构建判断矩阵,将和行归一法与特征向量法相结合,实现了对模糊层次分析法的改进;并将该方法运用到变压器剩余技术寿命评估模型中,提高了判断矩阵的客观性和合理性,丰富了评估的依据,评估结果更加准确并具有实际指导意义.更多还原

【Abstract】 In order to make the evaluation index weight more reasonable,and achieve the reasonable prediction of the remaining life of the power transformers,this paper used three-scale method to construct judgment matrix,and combined the line normalization method with eigenvector method to achieve the improvement of the fuzzy analytic hierarchy process.This method is applied to the transformer remaining life assessment model,has improved the objectivity and rationality of the judgment matrix,and enriches the basis for this assessment,the results of the assessment are more accurate and have the practical guiding significance.更多还原
