Characteristic Analysis and Control Method of a Novel Hybrid Injection Active Power Filter
摘要
Abstract
Due to high harmonic current and low reactive power in 35kV bus of a substation, a kind of high-power hybrid active power filter with dual-resonance injection branch is studied, which is suited for high-voltage level. In the analysis of its topology, the filter characteristics, reactive power compensation characteristics, voltage-sharing and current-sharing characteristics of dual-resonance injection branch are discussed. In order to enhance the stability of the system, dual closed loop control strategy of harmonic is proposed. The control aim of inner-loop is the output current of inverter and its controller is traditional PI controller. The control aim of outer-loop is the harmonic current of power grid. The novel recursive integral PI control method based on improved PSO-BP neural network is proposed for the non-straight control aim. The improved PSO-BP neural network is used to adjust the proportional and integral factors, with good steady state and dynamic performance. Research case study results verify the effectiveness and correctness of the content.关键词
