A Study on the Harmonics Analysis in Distribution System using SuperHarm

배전계통에서의 Superharm을 이용한 고조파 분석에 관한 연구

In recent years, both utilities and users have expressed their deep concerns about the quality of electric power. The harmonic is the one of power quality disturbance, it can raise a problem on the power system. In this paper, the increasing application of power electronic equipment [especially (ASDs adjustable speed drives)] on distribution systems has led to a growing concern for harmonic distortion and the resulting impacts on system equipment and operations. The purpose of this study is to calculate the quantity of harmonic voltage by varying the RECT side ASD load and to design the optimal harmonic filter for the elimination of harmonics.
