Abstract

Harmonic distortion commonly occurs with the use of non-linear loads which causes serious voltage fluctuation in power system network. PPF is the most common way to solve harmonic problems. On the other hand, APF has higher initial cost but is more effective because it injects harmonic voltage or current with the appropriate amount of magnitude and phase angle into the system to cancel-off the harmonics of non-linear load. These limitations can be reduced by using HPF as it is cost effective on high power non-linear load and has effective real-time compensation. The research objectives for this project are to investigate the 5th and 7th current harmonics in the power system network, to study various filters and control schemes in the power system network, and to analyse the THD present in the power system network before and after compensation. This research aims to contribute a step-by-step methodology and analysis of all three type of filters especially for HPF. In conjunction, different control schemes will also be used and analysed.
