摘要

提出了一种基于小波的低成本电压缺口检测与分析虚拟仪器。一个简单的小波分解树已经被用于检测和分析电压陷波的两个主要特征:与换相陷波的开始和结束相关的瞬态和信号频谱的平稳高频成分。实验结果表明了该方法在电压陷波时频特性检测和分析中的有效性。

Voltage notch detection and analysis using wavelets

This paper presents a low-cost virtual instrument for detection and analysis of voltage notches in voltage supply using wavelets. A simple wavelet decomposition tree has been used for detection and analysis of the two main features of voltage notching: the transients associated with the beginning and the end of the commutation notches and the stationary high-frequency components of the spectrum of the signal. The results obtained show the performance of the method proposed in the detection and analysis of the time-frequency characteristics of voltage notching.
