摘要

电力设备绝缘诊断的结果受很多不确定因素的影响，模糊集理论是处理这类问题的一种有效工具。文中介绍了输电线路绝缘子绝缘状况检测的模糊推理方法尤其是模糊关系矩阵的实现过程。通过对模糊运算输入输出参数的选择和模糊隶属度函数建立过程的分析，在对试验样本实验数据分析的基础上，利用最小二乘法实现了对模糊关系矩阵的求解。利用所求解的模糊关系矩阵在实验室和110 kV输电线路上分别进行了实验。实验结果表明，利用模糊推理方法实现输电线路绝缘子串在线检测是完全可行的，其操作的方便性和检测的准确性与现有方法相比具有较明显的优势。

Abstract

There are many uncertain factors affecting the result of fault diagnosis of power equipment. Fuzzy set theory is one of the effective tools to solve the problem. This paper proposes the insulation detection of insulator strings based on the realizing process with a fuzzy logical reasoning method

especially the establishment of the fuzzy relation matrix. The selecting process of the input and output fuzzy reasoning parameters and the establishing process of the fuzzy membership function is analyzed. By use of the least square method

the fuzzy relation matrix is derived from the input-output data of a large number of experiment results. With the aid of the established fuzzy relation matrix

the insulation condition of the insulator strings can be detected easily and correctly by using the new developed on-line detection algorithm. The correctness of the proposed method has been verified by experimental results from both the laboratory and 110 kV transmission line.
