Harmonic Analysis of Electrospindle System with Wavelet Packet Transform

Abstract

The electrospindle systems have been used in the maritime industry, they have recently become operative in automation systems. Along with the widespread use of harmonic generating machines and semi-conductor-based circuits in power and control systems, known reactive power compensation methods have been replaced by the use of filter- based compensation systems that consider harmonic distortion. This study used a voltage signal generated by an electrospindle generator with high harmonic distortion to obtain the amplitude time variation of the fundamental component by using Discrete Wavelet Packet Transform (DWPT). As a result of the analysis, it was observed that this method gives fast and accurate results that can be also used in real-time applications.
