基于logistics回归的直流偏磁现象判断

DC Bias Discrimination Based on Logistics Regression

本文中作者基于电网直流偏磁监测平台中中性点直流、振动、噪声监测变量,建立了logistics回归模型,用于判断变压器是否发生了直流偏磁现象。

Based on the monitoring variables of neutral point DC,vibration and noise in DC bias magnetic monitoring platform of power grid,a logistics regression model is established by the authors in this paper to judge whether DC bias magnetic phenomenon occurs in transformer.
