An Investigation Into The Design Of Dft- Based Controller For Reducing Harmonic Content In Active Power Hunt Filters

Sandeep Sunori, Parvesh Saini.


Selective harmonic compensation is essential for power quality evaluation, harmonic restoration, and other applications. There are many methods for correcting harmonics in a network, but discrete Fourier transform (DFT)-based solutions have gained popularity because of features including their ease of use and exceptional capabilities for selective filtering. For signals known only at N instants separated by T sample durations, the discrete Fourier Fourier transform (DFT) is equivalent to the continuous Fourier transform. In this work, a discrete Fourier transform (DFT)-based controller coupled with an active power filter (APF) is used for selective harmonic removal. The transient performance of the APF and the modeling approach are given careful, suitable design.

Key words: closed-loop, Active power, controller, compensation,
