基于距离函数的绝缘子故障诊断

Insulator Fault Diagnosis based on Distance Function

本文提出利用现代时间序列分析理论和距离函数，对输电线路绝缘子故障诊断的新方法。以输电线运行状态下绝缘子电晕脉冲电流为特征信号，采用Ｉｔａｋｕｒａ距离和Ｂｈａｔｔａｃｈａｒｙｙｓ信息距离为判别函数，分别进行绝缘子的故障诊断。诊断结果证明了该方法的有效性。

A new approach to diagnose insulator faults of a power transmition line is proposedbased on modern time series analysis theory and distance funetion. while the power line is inrunning state,a test on insulators is made to take the corona impulse current of the insulatoras characteristic signals and.Itakura distance as well as Bhattacharyya information distance ascritical function,to determine whether the insulator is sound or not. The result is proved tobe effective.
