Abstract
This paper presents a simple of Hybrid Power Filters System(HPFs) design techniques to minimize harmonic distortion that caused by a harmonic source such as ac drive and solar rooftop inverters. The predominant harmonic component is the fifth harmonic corresponding. As can be seen, there is heavy resonance at fifth harmonic when solar inverter are connected to the system, the consequences was that the equipment will eventually fail or sometimes by literally exploding. A novel method for implementation of the HPFs is presented to avoid this problem. The HPF arrangements where are three branches for fifth and seventh harmonic filter by tuning to the 250, 350Hz and active filter which, can be reduced harmonic more than the other techniques. The major objectives of this paper are to improve the power factor, to reduced current and voltage distortion and to reduce resonance problems at a system. Practically, it is ensured that the HPFs are best applied for grid-connected solar rooftop power system. After installing the HPFs, the harmonic distortion can be lowered than IEEE 519 standard. The results show that the association of HPFs is a very good solution for harmonic problems.
