摘要

针对气体绝缘组合电器（gas insulated switchgear，GIS）现场振动检测中存在其他设备产生的低频噪声、高频噪声以及环境随机噪声，难以提取其有效振动信息的问题，提出一种基于FFT奇异值分解（singular value decomposition，SVD）和改进变分模态分解（variational mode decomposition，VMD）的联合降噪方法。该方法首先利用FFT奇异值分解对原始信号进行预处理，直接滤除低频噪声；然后利用混沌灰狼优化算法（chaotic grey wolf optimization，CGWO）对VMD进行参数优化，得到一系列本征模态函数（intrinsic mode function，IMF）；再将IMF与预处理后信号进行互相关系数以及阈值的计算，对大于计算阈值的IMF通过FFT奇异值分解二次去噪；最后重构振动信号，GIS现场本体振动数据的特征得到增强。结果表明：与CGWO-VMD和小波阈值降噪相比，所提出的算法可以去除高幅值低频噪声、高频噪声以及随机噪声信号，保留GIS本体振动的基频和谐波分量，为GIS现场振动抗干扰检测和机械缺陷诊断提供了技术支持。

Abstract

In view of the problem that it is difficult to extract effective vibration information from low-frequency noise

high-frequency noise generated by other equipment

and environmental random noise in the field vibration detection of gas insulated switchgear(GIS)

a joint noise reduction method based on FFT singular value decomposition (SVD) and improved variational mode decomposition(VMD) is proposed. Firstly

the method uses FFT singular value decomposition to pre-process the original signal and directly filters out low frequency noise. Then

the parameters of VMD are optimized by using the chaotic grey wolf optimization (CGWO) algorithm to obtain a series of intrinsic mode functions (IMF). After that

the cross-correlation coefficient and threshold of IMF and preprocessed signal are calculated and IMF larger than the calculated threshold is denoised again by FFT singular value decomposition. Finally

the vibration signal is reconstructed

and the GIS field ontology vibration data characteristics are enhanced. The results show that compared with CGWO-VMD and wavelet threshold noise reduction

the proposed algorithm can remove high amplitude low frequency noise

high-frequency noise and random noise

and retain the fundamental frequency components and harmonic components of GIS body vibration

which provides technical support for field vibration anti-interference detection and mechanical defect diagnosis of GIS.
