ZHANG Zhiwen, ZENG Lingxiong, XIE Bin, et al. Control method of hybrid inductive filtering system based on energy model[J]. 2018, 38(10): 101-107. DOI: 10.16081/j.issn.1006-6047.2018.10.016.
A novel HIAF( Hybrid Inductive Active Filtering) system is proposed for industrial distribution network.The path of harmonic flow and the benefits to converter transformer and system with HIAF added are analyzed. The compensation mechanism of HIAF is analyzed according to the three-phase equivalent circuit of the system and the mathematical model of HIAF is built. Based on the idea of PBC( Passive-Based Control)
the EL( Euler-Lagrange)model of the system in dq coordinate system is established. The controller is designed with the damping injection method and the compensation characteristics of HIAF. Simulative and experimental results verify the correctness of the proposed compensation system and control method.
