基于灰关联分析的MOA绝缘监测和诊断参量研究

Investigate on Monitoring and Diagnosis of MOA Parameter Based on Grey Relational Analysis

对MOA进行在线监测是非常必要的,为了选取合理的监测和诊断参量,从灰色系统理论的基本思想出发,将灰关联分析应用于MOA的监测和诊断参量的分析中,并以实例经计算比较,认为采用阻性泄漏电流基波峰值作为参量来监测和诊断MOA的绝缘状态是比较合理的。

It is necessary for on-line MOA monitoring.To select the MOA parameter monitoring and diagnosis,the grey system theory is introduced.The grey relational analysis is used in MOA parameter monitoring and diagnosis.With verification and evaluation on an example,it proved that it is reasonable to take the peak value of basic wave of resistive leakage current as the reference one.
