Control Strategy of Active Power Filter Based on Modular Multilevel Converter
To improve the capacity,pressure resistance and the equivalent switching frequency of active power filter(APF),a control strategy of APF based on Modular Multilevel Converter(MMC)is presented.In this Control Strategy,the indirect current control method is used to achieve active current and reactive current decoupling control; Voltage Balance Control Strategy is to stabilize sub-module capacitor voltage,the predictive current control method is used to Track and control of harmonic currents.As a result,the harmonic current is restrained,and power quality is improved.Finally,the simulation model of active power filter controller based on MMC is established in Matlab/Simulink,the simulation proves that the proposed strategy is feasible and correct.
