摘要/Abstract

摘要： 由于有载分接开关(on-load tap changer, OLTC)需要频繁切换和具有严格的运行条件,OLTC已成为电力变压器中最脆弱的部分之一,OLTC故障的准确诊断对保障电力系统稳定运行意义重大。基于变分模态分解将OLTC振动信号分解为数个模态分量,基于模态分量提取OLTC振动信号的时域特征参数,并利用一系列故障模拟对OLTC振动信号时域特征参数进行统计性分析。通过这些时域特征参数建立OLTC振动信号数据库,从而实现OLTC故障的诊断。

Abstract: Due to the frequent switching and strict operating conditions of on-load tap changers (OLTC), OLTC has become one of the most vulnerable parts of power transformers. The accurate diagnosis of OLTC fault is of great significance for ensuring the stable operation of the power system.Based on variational modal decomposition, the OLTC vibration signal is decomposed into several modal components. The time-domain characteristic parameters of the OLTC vibration signal are extracted based on the modal components, and a series of fault simulations are used to statistically analyze the time-domain characteristic parameters of the OLTC vibration signal. By establishing these time-domain characteristic parameters, an OLTC vibration signal database is established to achieve OLTC fault diagnosis.
