불평형 전원시스템을 고려한 3상 능동전력 필터에 관한 연구
A Study on a 3-phase Active Power Filter Under Unbalanced Input Voltage
초록
An important assumption for the active power filter design using instantaneous power theory and the d-q transformation method in a 3-phase power system is based on balanced 3-phase system. However, under pratical conditions, the 3-phase power system can not be continuously balanced due to unbalanced loading. In this paper, a method to control the 3-phase active power filer using instantaneous power theory and the d-q transformation under unbalanced power system is presented and the theoretical results are verified by simulated results.
