A proposed methodology to analyze systems with distributed harmonic sources

Abstract

Harmonics is one of the major disturbances that affect the power quality of electric utilities. Many techniques were used to analyze the harmonics in power systems. These techniques generally have difficulties in determining the collective impact of distributed harmonic sources. This paper introduces a proposed methodology for analyzing harmonics in distribution systems with distributed harmonic sources. The method takes into account the effect of diversity and attenuation. The method is illustrated through a numerical application applied on a real distributor.
