저압 전원계통에서 고조파 양상의 분석에 관한 연구

초록

Abstract This study aims to describe the theory of harmonics as a basic research of harmonics reduction of low voltage power system and to examine the aspects of harmonics being made at low voltage power system. At first, the study investigated the effect of harmonics upon power system and equipment, etc and examined advanced countries' harmonics control standards in various ways. Based on the research results, the study investigated carefully not only current measures of harmonics reduction but also the advantages and disadvantages of the application to low voltage power system. In addition, more than 10 consumers were selected to examine harmonics of various kinds of power systems by power analyzer and to measure voltage and current waveform de! pending upon kinds of loads and to evaluate the inclusion of harmonics and investigate harmonics depending upon each load.
