摘要
This paper presents a shunt active power filter (SAPF) based on voltage detection method to control harmonic voltage in a radial distribution feeder. The harmonic voltage distortion is suppressed by injecting appropriate harmonic currents into the system. The proposed voltage-detection SAPF has a novel multi-channel complex-gain controller, which is designed to improve system stability margins and to make the SAPF output tunable. The system model including both the proposed SAPF and a typical building distribution system is developed. Transfer functions in the s domain are derived for both SAPF and distribution components in multiple reference frames. Characteristics of the proposed SAPF in the system are then investigated. The computer simulation and experimental results verifies the analytical analysis.
