In this seminar a method for wideband harmonic compensation is presented. The main circuit configuration of the system is shown in Fig. 2. The system compensates the low order harmonics using a simple computational control delay compensation method, while the high order harmonics are filtered with a small passive high pass filter. In the system the whole filtering band of the APF is utilized and the filtering performance is recovered with an HPF when the ability of the APF to filter harmonics effectively is impaired. This way the size of the pa ....etc

ABSTRACT

This paper focuses on a shunt active filter based on the detection of harmonic voltages at the point of installation. The objective of the active filter is to attenuate harmonic propagation resulting from series/parallel resonance between capacitors for power factor correction and line inductors in a power distribution line. The active filter acts as a low resistor to the external circuit for harmonic frequencies, and it is installed on the end bus of the power distribution line, just like a 50 O terminator installed on the end ter ....etc

Iam a final year b.tech student of EEE branch. I hav just started with my project work(Harmonic Reduction in Three phase Parallely Connected Inverter).Iam facing problem in triggering the thyristors using MATLAB,Simulink software as i do not know anything about the MATLAB software. Can anyone please guide me in solving this problem and give information regarding my project? The methods which i want to use to reduce harmonics are:
1.filters
2.transformer connections
3.Pulse Width Modulation(PWM)
4.Third Harmonic Injection Pulse Width Modulat ....etc

Abstract

A filter is a system that processes a signal in some desired fashion.
A continuous-time signal or continuous signal of x(t) is a function of the continuous variable t. A continuous-time signal is often called an analog signal.
A discrete-time signal or discrete signal x(kT) is defined only at discrete instances t=kT, where k is an integer and T is the uniform spacing or period between samples

NOVEL ACTIVE POWER FILTERS FOR HARMONICS SUPPRESSION



INTRODUCTION
CONCEPT OF HARMONICS
Harmonics can be defined as entities having a frequency in integral multiples of the fundamental frequency. This means, if we have a fundamental frequency of ‘f’ Hz, the entities 2f, 3f, 4f, 5f etc. are called as harmonics. During the past decades many power electronic devices such as 6-pulse converters, variable speed motor drives, and other power electron ....etc
