Adaptive Harmonic Current Compensation Method with SAPF based on SOGI
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018The shunt active power filter (SAPF) cannot compensate harmonic and reactive current completely when capacity is limited. Aiming at the problem, an adaptive harmonic compensation control method based on second order generalized integrator (SOGI) is proposed with calculating APF’s capacity strictly.

Adaptive control for MMC-SAPF with balanced and unbalanced PCC voltage
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017Three-phase three-wire shunt active power filter (SAPF) with traditional positive-sequence control can only compensate part of the nonlinear load current harmonics if the PCC voltage changes from balanced to unbalanced condition. Changes of both nonlinear load current harmonic components and equivalent circuit for modular multilevel converter based ...
