Abstract With the rapid development of wind power industry, total installed capacity has increased dramatically worldwide, and a large number installations need to be connected grid. In turbines, voltage flicker due output fluctuations caused by speed changes, application Voltage Source Converter (VSC) cause harmonic richness other quality problems become more prominent. this regard, research i...

This paper presents practical experiments on a harmonic rejection down-mixer, which offers up to 75 dB of harmonic rejection, without an RF filter. The down-mixer uses a two-stage approach; the first stage is an analog multi-path/multiphase harmonic rejection mixer followed by a second stage providing additional harmonic rejection based on blind adaptive interference canceling in the discrete-t...

A new method for designing uniform and nonuniform digital filter banks with a specified composite response is presented. The composite response of the filter bank can be met either exactly or to within a given tolerance. We focus on filter banks in which the individual filters are finite impulse response (FIR) digital filters of possibly nonequal length, although the new method is applicable ev...

The diffusion of nonlinear loads and power electronic devices in systems deteriorates the signal environment, increases difficulty measuring harmonic phasors. Considering accurate phasor information is necessary to deal with related issues, this paper focuses on realizing dynamic estimation when contaminated by certain interharmonic tones, i.e. out-of-band interference (OBI). Specifically, work...

Here we report a new motion illusion where the prevailing motion direction is strongly influenced by the relative phase of the harmonic components of the stimulus. The basic stimulus is the sum of three sinusoidal contrast-reversing gratings: the first, the third, and the fifth harmonic of two square wave gratings that drift in opposite direction. The phase of one of the fifth components was ke...

In this paper presents a fast new PI controlled DSTATCOM used to compensate for harmonic distortion in threephase system. The DSTATCOM employs a simple Method for the calculation of the reference compensation current based. The presented DSTATCOM is able to operate in balanced, unbalanced and Variable load conditions. Classic filters may not have satisfactory performance in fast varying conditi...
