| 摘要: |
| 为了评价绝缘子污闪状态，提出基于熵权法的绝缘子污闪状态模糊综合评价模型。建立表征绝缘子污闪状态的模糊评价指标体系以及评语集，运用熵权法确定各评价指标的权重，采用三角形和半梯形结合的隶属度函数描述各指标的模糊性。重点研究和分析了评价模型的建立过程，包括评价指标选取及层次划分、权重确定方法。对某500 kV线路绝缘子污闪案例进行分析评价，结果与实际状况相符，证明了所提方法的正确性。 |

| Abstract: |
| A comprehensive fuzzy evaluation model based on entropy weight method is proposed for insulator flashover pollution，for which，a fuzzy evaluation index system and its comment set are established to represent the insulator flashover conditions. The entropy weight method is applied to determine the weights of evaluation indexes and the combined triangular and semi-trapezoidal membership function is adopted to describe the ambiguity of each index. The steps of evaluation model establishment are emphatically studied and analyzed，including evaluation index selection，hierarchical division and weight determination. A case of 500 kV line insulator flashover is analyzed and the results coincide with the actual conditions，verifying the validity of the proposed method. |
