摘要

本文提出了一种变分模态分解(VMD)算法，并首次将其应用于间谐波的检测。给出了基于VMD的间谐波检测的具体过程。将待检测的功率信号通过VMD分解为若干个本征模态函数(IMF)分量，然后通过Hilbert-Huang变换(HHT)提取得到的IMF分量，得到其间谐波频率和幅值参数。仿真和实测结果表明，VMD是一种有效的间谐波检测新方法。

A Novel Methodology of Inter-Harmonic Detection Based on VMD

This paper presents a variational mode decomposition (VMD) algorithm and applies it to the detection of inter-harmonics for the first time. The specific process of inter-harmonics detection based on VMD is provided. The power signal to be detected is decomposed into several Intrinsic Mode Function (IMF) components by VMD, then the inter-harmonics frequency and amplitude parameters is obtained by extracting the resulting IMF component through Hilbert-Huang transform (HHT). The simulation results and practical measurements show that VMD is an effective new method for detecting inter-harmonics.
