基于大数据的局放在线监测与诊断
|
摘要
局放是高压电气设备绝缘的重要表现特征。本文基于现有局放值求解局放的RMS值,掌握局放变化情况,同时设计了局放特征提取方法,采用Xgboost算法对标准故障局放的特征信号进行建模,实现对局放故障的准确诊断。
Partial discharging is the main performance characteristics of high voltage electric equipment insulation.The RMS value is calculated on the basis of the existed partial discharging value, so as to master the situations of changing of partial discharging, and on the basis of designing of a method for feature extraction of partial discharging,and establishing of model for characteristics signals in standard faulty partial discharging by means of Xgboost algorithm, the accurate diagnosis for faulty partial discharging is realized.
