고정 좌표축상에서의 전압 보상 기능을 가진 능동전력필터 제어기설계 및 시뮬레이션 = A Controller Design and Simulation for APF with Voltage Regulation on Stationary Reference Frame

다국어 초록 (Multilingual Abstract)

This paper deals with a simple control algorithm of shunt active power filter (SAPF) to reduce the source current total harmonic distortion (THD) and compensate the point of common coupling (PCC) voltage distortion caused by the interaction current harmonic components with system impedance. The proposed SAPF is implemented with three-phase IGBT based voltage source inverter (VSI) with a dc bus capacitor. The proposed simple control algorithm is based on not the synchronous reference frame but the stationary reference frame. Therefore, compared to the conventional SAPF, the proposed SAPF provides reduction of computation. To prove the validity of the proposed control algorithm, computer simulation is executed.
