چکیده
This paper presents an adaptive harmonic current extraction scheme using notch filters combined with a modified discrete wavelet-packet transform (DWPT). The is applied to MMCC-STATCOM for mitigating harmonics distortion in power line. DWPT incorporates data expansion technique overcome the limitations of boundary effect. It identifies rms values dominant elements non-stationary real-time, these being used update order and stop-frequency filter chain. embedded control system generate reference current. results have shown that tracks changes faster more accurately than conventional method. enables STATCOM adapt quickly load changes, hence giving accurate elimination real-time.

متن کاملOn the Discrete Harmonic Wavelet Transform
The discrete harmonic wavelet transform was developed by Newland in 1993 1, 2 . Similar to the ordinary discrete wavelet transform, the classical harmonic wavelet transform can also perform multiresolution analysis of a function. In addition, it has a fast algorithm based on fast Fourier transform for numerical implementation. A distinct advantage of harmonic wavelets is that they are disjoint ...
متن کاملNoise Cancellation by Combining the Discrete Wavelet Transform With the Wiener Filter
In this study by using noise-free signal estimation the reduction of noise in the image is being proposed. The dyadic stationary wavelet transform is used for both the wiener filter and in estimating the noise free signal. Finding a suitable filter bank and choosing other parameters of the wiener filter with respect to obtained signalto-noise ratio (SNR) is our goal. Testing was being performed...
متن کاملAn Lifting-Based Discrete Wavelet Transform and Discrete Wavelet Packet Processor with Support for Higher Order Wavelet Filters
The major challenge in the wavelet transforms is that there exist different classes of wavelet filters for different kinds of applications. In this chapter, we propose a generalized lifting-based wavelet processor that can perform various forward and inverse Discrete Wavelet Transforms (DWTs) and Discrete Wavelet Packets (DWPs) that also supports higher order wavelet filters. Our architecture i...
متن کاملAn efficient approach to machine health diagnosis based on harmonic wavelet packet transform
This paper presents an efficient approach to machine condition monitoring and health diagnosis, based on the Discrete Harmonic Wavelet Packet Transform (DHWPT). Specifically, vibration signals measured from a bearing test bed were decomposed into a number of frequency sub-bands, and key features associated with each sub-band were selected, based on the Fisher linear discriminant criterion. The ...
