【Abstract】 This paper presents an analysis of a parallel dynamic monitoring system for APF based on the load current detection,including the system structure and a control scheme.The proposed APF can be provided with a multifunction,such as power compensation,harmonic suppression and current balance in a three-phase power system.Experimental results have proved that the control method is more adaptive to the change of the system parameters and obtained a better power compensation effect.更多还原
